Hulls of Steel & Co.

By | Article, Technology | No Comments

Hull: Bulwark Against the Seas

Sailing in high seas was never a task for the faint at heart. Giant waves toss the ship up and down while ferocious, howling winds and angry raindrops lash out with full might. Life hangs in balance as the deck beneath your feet shivers violently and the skies literally turn dark while it is still day time.

You can tide over such hostile waters only with nerves of steel. Of course, it helps if your ship has a hull of steel or other tough materials to complement your steely nerves. Forget rough seas, even calm seas are lethal because seawater is amongst the most corrosive of environments.

Hulls are the most important technical and economical design parameter of a ship. They determine its safety, stability, and structural integrity while making up around 20% of the ship’s total cost.

Shipbuilding Steel is the most common hull material. Other materials include aluminum and titanium alloys, fiberglass, composite materials, and wood. Workmanship though is equally important. Skilled workmen will build wonders out of humble wood while unskilled craftsmen will make a mess out of the finest aerospace-grade composites.

Hull-Building Materials

Following properties are important for hull-building materials:

  • Strength is the resistance to permanent deformation and breaking. It can be:
  • Yield Strength: stress i.e. force per unit cross-sectional area at which materials are unable to recover their original shape
  • Ultimate Strength: stress at which materials break

  • Strength Efficiency is strength relative to density. Equivalent to the Strength-to-Weight ratio, it is an excellent measure of structural efficiency
  • Stiffness is the resistance to deformation under load. A material may be strong enough not to break, but may not be stiff enough and will bend making is useless. Deflection depends on the material stiffness and the situational geometry

Young’s Modulus measures a material’s stiffness. It is the ratio of stress applied on the material to the strain produced

  • Stiffness Efficiency is stiffness relative to density
  • Flexibility
  • Weld-ability
  • Manufacturability
  • Repair-ability
  • Cold Resistance

Fiberglass and steel have great strength while aluminum alloys and wood possess lesser strength. However, fiberglass has higher strength efficiency and so does wood and aluminum with heavier steel falling behind. All steels have high values of Young’s Modulus while aluminum, fiberglass, and wood have lower values. The stiffness efficiency of all these materials is nearly same.

Stiffness increases with increasing thickness of the cross section in the direction of the load. Doubling the thickness of a rectangular beam makes it eight times stiffer. But making the sections thicker adds to the weight. This is precisely why we use I-beams – increasing thickness without adding much weight.

Considerations when choosing materials:

  • Steels are heavy and corrosion-prone but hard, easy to fabricate into large hulls, and abrasion resistant

Cold-Proof Welding Hull Steels perform well up to temperatures of -600C. They find application as icebreaker hulls and lighter-abroad ships. They are highly process-able and resistant to layered failures and cracking

High-Strength Clad Corrosion-Resistance Steel makes hulls of ice-ships and icebreakers. The material increases serviceability, eliminates corrosion-erosion wear, reduces required quantity of metal per structure, and lowers loads on hulls arising from breaking away of ice-floes and heavy sticking

High-Strength Non-Magnetic Steels make good hulls with high-strength, non-magnetic properties, reliability, durability, compatibility with pearlitic steels when operating in corrosive media, and top mechanical properties over wide temperatures

Nitrogen-Alloyed Steels provide high-strength, absolute corrosion resistance, flexibility, and non-magnetic behavior due to the unique combination of the atoms of iron and carbon with nitrogen. Pearlitic Steels are two-phased steels with alternating layers of alpha-ferrite (88% weight) and cementite (12% weight)

  • Fiberglass is the most environment-friendly hull-building material. Its chemical and biological stability translates into least emission of chemicals into water and air. It is also perhaps the strongest material, is inexpensive, and even unskilled labor can mass-produce fiberglass hulls

It does however require enormous initial investment making it compatible only with large scale production. Plus, it hides second-rate workmanship making buyers apprehensive

Trawlers, yachts, high-speed airfoil and hydrofoil crafts, and sweepers typically use fiberglass hulls

  • Aluminum is lighter, easier to work, and corrosion resistant vis-à-vis steel. It has saved many riverboats from sinking because it deforms on impact, it does not break. However, it is tougher and more expensive to weld aluminum

Hydrofoil and airfoil ships, high-speed crafts, and aerostatic vessels use aluminum-alloy hulls

  • Wood is visually captivating but piles up maintenance bills. Wood-Fiberglass composites are inexpensively maintained but are suitable only for short or one-off production


All said and done, there is no single material with all the desirable properties. The application determines the choice of material and there is always a trade off. Fiberglass and composites hold great promise for advances in material science have always furthered human development.

A Luxury Cruise With ‘Secret’ Stops

By | Article, Technology | No Comments

Would you go on a luxury cruise not knowing the exact ports of call? A luxury liner is betting some adventurous cruisers would, as they make a gutsy offer for an increasingly discerning cruise industry market—an itinerary with ‘secret’ destinations.

Germany-based Hapag-Lloyd Cruises offered a “surprise cruise” on the 2-year-old, 516-passenger MS Europa 2 earlier this May. The most passengers would know about the trip before it begins is that it takes them from Istanbul to Athens, with stops in between to be decided only when the ship sets sail. How does it work? The Captain was to present possible destinations, and a lecturer was also available to talk about the merits and charms of the ports. The guests would then come together to design their trip.

Included in the potential list of stops are destinations with each of their own thrills, like the Byzantine town of Kavala, the beaches of Limenas, the biblical metropolis of Thessaloniki, the excavation site of Dikili, diving destination Chios… just to name a few of the exciting possibilities. The ten-night sailing was priced starting at $5,990 per person on double-occupancy.

We at Kemplon Engineering, as proud service providers to the maritime community since 2005, are always floored by what the cruise industry has to offer the tourism market. From the floating engineering wonders that are today’s magnificent cruise ships to stunning destinations and, like the news above, fresh ideas and offerings, there is always something new and exciting to watch out for and talk about.

Drilling Anew Near Site of Deepwater Horizon Disaster

By | Article, Technology | No Comments

Environmental disasters of unprecedented scale cast long shadows. 2010’s Deepwater Horizon oil rig explosion and oil spill may have occurred five years ago, but memories about it are still fresh and many of its consequences are still unfolding. News still comes out on legal accountabilities and penalties, and the extensive environmental impact of the event is yet to be understood. It is no wonder then, that news of plans for drilling to start near the site of the disaster is worrying to many.

The Deepwater Horizon Disaster began with the explosion of an oil rig in the Gulf of Mexico, leading to what is believed to be the biggest marine oil spill of all time. 11 workers were killed, and millions of other lives were affected when thousands of barrels of oil per day discharged into the water. The Gulf Coast economy was particularly hard hit, with fears of contaminated fishing, a moratorium on drilling, and a slump in tourism. Thousands of marine animals suffered from the oil too, with illnesses and deaths tracked years later still being linked to the disaster.

Louisiana’s LLOG Exploration Offshore LLC is planning to drill near the site, with a permit for a new well approved by authorities. According to a representative for the company, their staff maintain fresh memories of the disaster and is committed to prevent it from happening again. The development is worrying some, however, who find the site particularly dangerous. Worries have also been raised on this smaller company’s financial capacity to respond to a potential disaster and make consequent pay outs, if it does not have the ‘deep pockets’ of a player like BP. Authorities have reportedly reviewed the company’s plans extensively, however.

Like many all over America, we at Kemplon Engineering, watched the 2010 disaster with grief and worry for the future. As providers of engineering services to the maritime industry for over a decade, we are one with the maritime community in hoping such a disaster will never happen again – for the safety of workers, marine life and the communities that depend on the water for livelihood, and for the continuing operations of responsible and sustainable drilling. May this latest development bring the area a more positive outcome.

Ocean Eagle 43 Trimaran Offshore Patrol Vessel (OPV)

By | Uncategorized | No Comments

A Wonder Offshore Patrol Vessel (OPV)
French shipyard Constructions Mecaniques de Normandie (CMN) launched the first of the three Ocean Eagle 43s in January this year and conducted sea trials in February. CMN will now deliver the vessels to Mozambique. H2X Shipyard at LA Ciotat, France built the hull.

In a €200million, September 2013 deal, the Mozambican government ordered three Ocean Eagle 43s, 24 fishing vessels, and three HSI 32 Interceptors from CMN to guard the facilities around its recent offshore gas and oil discoveries.

These days, navies have to undertake diverse missions including low intensity ones. Combining aerial surveillance with follow-up surface action is important to protect against a range of threats. And, navies have to do so within tight budgetary constraints.

Currently, the Mozambique navy is powered only by a couple of Namacurra Class Harbor Patrol Boats donated by South Africa, one Conejera Class Patrol Craft (Pebane) donated by Spain, and about ten small patrol crafts including Rigid Hulled Inflatable Boats (RHIBs).

Mozambique & East Africa: Sitting Atop Resource Gold
A former Portuguese colony, Mozambique gained independence in 1975. The joy was short lived for a civil war erupted in 1977 and lasted till 1992. The country held its first multiparty elections in 1994 and has been stable since. The government then embarked on reform programs but the country remains poor and underdeveloped.

With offshore oil and gas discoveries, things are looking bright for Mozambique, Tanzania, Kenya, and Uganda. In 2012, operators in Mozambique hit 100Tcf of natural gas. The U.S. Geological Survey estimates Mozambique and Tanzania’s reserves at 250Tcf gas and 14.5billion barrels of oil.

Although politically stable, East Africa is plagued with deficits in infrastructure, regulatory framework, and skills. The political leadership has its task cut out to address these if it has to retain foreign investors, exploit resources, and use the proceeds for development.

Ocean Eagle 43 Trimaran OPV: Technical & Other Details
Back in 2012, specialist designer-operator of sea based projects ProLarge and air-marine service company Sea Team Aviation joined forces with CMN to create a light, fast, and yet reliable patrol trimaran employing innovations in ocean racing crafts. Soon, Nigel Irens, the designer of multi hulls such as Brigitte Bardot and Ilan Voyager, joined them.

KE - image 3

Ocean Eagle 43 Trimaran Offshore Patrol Vessel (OPV) (Source:

Ocean Eagle 43 OPV comes with a creative trimaran design specifically built for patrolling shallow waters. It coasts along at 15 knots for 238 nautical miles while using up a meager 1 ton fuel.

Combining a very slender hull with two floats lends the craft exceptional stability, fantastic fuel economy, incredible speed, and autonomy with reasonable comfort levels in moderate to rough seas.

Special features:

  •  Fantastic Fuel Economy: the craft can cover 238 nautical miles at 15knots consuming only 1 ton of fuel. At the same speed and using the same amount of fuel, a mono-hull OPV will cover only 50 nautical miles
  • Unmanned Aerial Vehicle: substantially raises the line and range of sight
  • High Modularity Levels: make the vessel compatible with diverse maritime surveillance missions
  • Exceptional Operational Viability
  • Simple Maintenance and Top Reliability: you can change the main propulsion engine within 24 hours

Ocean Eagle 43 Trimaran OPV Data Sheet

KE - table

Adaptable for special operations support, side scan sonar operations, coastal oceanography, and surveying, the Ocean Eagle 43 can undertake:

  • state action at sea
  • sea policing
  • safety at sea
  • combating smuggling, piracy, illegal immigration, and trafficking
  • search and rescue (S&R)
  • convoy escort
  • defense of offshore installations and vulnerable vessels
  • safeguard against asymmetric threats, boarding of terrorists, and speedboats
  • overseeing marine environment
  • inspection of fishing zone and exclusive economic zone

Asymmetric Threat is an unfair threat. It comes from weaker forces that do not try and match the size of its larger adversary but exploit its adversary’s weaknesses. These asymmetrical forces are small, mobile, efficient, elusive, high tech, and inventive. Guerilla warfare for example is asymmetrical warfare.

For conducting missions, the craft is loaded with:

  • 1 x electro-optical observation system
  • 1 x 20mm remote-controlled gun turret
  • 1 x radio direction finder
  • 2 x 12.7mm side gun
  • 1 x rotary UAV
  • 1 x C2 system

Main equipment and auxiliaries:

  • RHIB: stern ramp-mounted, 7m outboard RHIB for transshipments, policing intervention, or naval special operations
  • 4 x diesel engines
  • 2 x main generators
  • 2 x CPP

Through a ‘what’s needed when its needed’, the Ocean Eagle 43 undertakes a whole range of missions. Just what the Mozambique navy ordered.

Asia’s Migration Crisis: Saving the Rohingya Muslims

By | Article, Technology | No Comments

Refugees fleeing poverty and persecution in their home countries by boat are being turned away from landing on other countries. This is the plight of so-called ‘boat people’ in the waters of Southeast Asia, reportedly comprised of poor Bangladeshis and Rohingya Muslims fleeing the predominantly Buddhist country, Myanmar, where they are not considered citizens. Thousands of people are said to be drifting – and dying – at sea in inhumane conditions, rejected from going on shore by Thailand, Indonesia and Malaysia.

Rohingya have been described by the United Nations as one amongst the most persecuted peoples of the world. Many of those striving to reach refuge on foreign shores are stateless Muslims from Myanmar and Bangladesh. By some estimates, in the first months of 2015 alone, about 25,000 poor Bangladeshis and Rohingya migrants have gone on smugglers’ boats in hopes of a better life in foreign shores. A tougher stance on human trafficking in Thailand, however, triggered an uptick in arrivals to neighboring Malaysia and Indonesia too – countries that have also been wary of taking in the new arrivals.

There have been reports of navies refusing loaded migrant boats from reaching shore, and of boats being turned away and even being pushed back out to sea to uncertain fates. Many migrants have reportedly died of drowning, starvation and sickness as they drift aimlessly, abandoned by the smugglers who have arranged for their passage.

The three nations concerned have since been in coordination on a proper course of action. Indonesia and Malaysia have decided to give the migrants temporary shelter of up to one year, and Malaysia is now actively involved in search and rescue in areas of their responsibility. It is said that over 3,000 refugees could still be drifting at sea.

International pressure has also been focused on Myanmar to address the root of the problem – the persecution of the Rohingya.

Like Europe’s Migration Crisis, this issue prompts us all to ask very important questions about humanitarian aid in modern times. How much should foreign governments like Thailand, Indonesia and Malaysia be responsible for the influx of irregular migrants literally dying to reach their shores? Controlling the border and simply keeping the migrants out, irrespective of the fate that awaits them on the open seas seems inhuman, and yet how much should these nations be expected to do search and rescue, on top of accepting, processing and looking after the migrants who do reach their shores? Can national economies sustain the financial burdens associated with these tasks? And because Asia’s waterways are among the busiest in the planet, sooner or later, commercial operators may also have to ask themselves similar questions posed to national coast guards and navies – how much assistance can and should be given to hundreds of people struggling at sea?

Kemplon Engineering, as a provider of engineering services to the maritime community since 2005, is concerned with this important issue. Like the maritime industry we so proudly serve, we have a great love and respect for our seas. The world’s waters have witnessed humanity at its best and worst. It has seen our engineering marvels, spirit of exploration and adventure, and heroism. It has, unfortunately, also seen us in war, environmental exploitation, tragedy and desperation. It is our sincere hope that this crisis brings out the best in all of us, instead – cooperation among governments, inventive solutions, and compassion for each other.

Italian Navy on a Modernization Spree

By | Article, Technology | No Comments

Continued Expansion
Recently, the Italian Navy ordered six Multipurpose Offshore Patrol Ships (PPA) and One Logistic Support Ship (LSS). This comes shortly after it ordered two more FREMM Frigates in April this year completing its planned quota of ten frigates.

This latest contract is worth €3.5billion ($3.9billion). Italian shipbuilder Fincantieri’s share in the expansion is worth €2.3billion ($2.6billion) while Finmeccanica will undertake €1.2billion ($1.4billion) worth expansions.

Apart from the geo-political implications – these vessels will renew Italy’s naval role in the Mediterranean – the development has benign implications for Italy’s shipbuilding industry and overall economy for the contracts will deliver value many times the worth of investments.

Scheduled date for the delivery of the first of the six PPAs is 2020 while the LSS will be ready for operations by 2019. Integrated Shipyard at Riva Trigoso and Muggiano will build the PPAs.

Italy is a crucial participant in European Union (EU) operations for patrols and migrant rescue in the Mediterranean. Migrants are a massive crisis in the Mediterranean as thousands risk their life and limb to illegally crossover into the EU aboard flimsy, unsafe boats. Disasters are only waiting to happen.

Migration Zone of the Mediterranean (Source:

Migration Zone of the Mediterranean

Libya is the dispatch point for migrant vessels. Conflict-ridden people from Libya, Syria, Somalia, Nigeria, and Congo seek to cross the Mediterranean. Most migrant boats head for the Italian island of Lampedusa, a tourist haven near the North African coast.

In October 2013, over 300 migrants drowned near the Lampedusa Island. The tragedy made the Italian government launch the Mare Nostrum Search and Resuce Operation that saved 140,000 migrant lives between October 2013 and October 2014. EU Border Agency Frontex-executed Operation Triton succeeded Mare Nostrum in November 2014 and has saved 22,300 migrants till February 2015.

Unlike, Mare Nostrum that operated in international waters to ‘search and rescue’, Triton is active only within 30 nautical miles of the Italian coast and focuses on ‘border control and surveillance’. Plus, Triton worked on a third of Mare Nostrum’s budget. These limits proved fatal for many. Already 1,700 have drowned in 2015.

Now, the EU has tripled Triton’s budget to €120million ($130million). Maritime law requires private ships to rescue in-trouble vessels if they are in the vicinity. However, ships go off the radar when rescue centers call them to aid distressed vessels making official rescue operations absolutely necessary.

The Vessels
Both classes of vessels operate as vessels of war, on-sea rescue operation ships, and as civil protection vessels. Incorporating innovation, these vessels are efficient and flexible for operating in numerous capacities.

Most importantly and in sync with the current climate favoring green technologies, these ships leave a low environmental impact on account of their cutting edge biological waste control and low emission auxiliary propulsion system.

Multipurpose Offshore Patrol Ship (PPA) will cruise at speeds exceeding 31knots and is capable of accommodating a crew of 171 on its 129m long frame. The PPA:

  • works as a first line fighting vessel in its most equipped version as well as a sea rescue ship and patrolling vessel in less developed forms
  • operates high-speed Rigid Hull Inflatable Boats (RIB) of up to 11m length using lateral cranes or a hauling ramp located at the far end of the stern
  • embark on diverse containerized logistic, operating, or healthcare modules
  • Combined Diesel and Gas Turbine Plant (CODAG)-equipped
    Logistic Supply Ship (LSS) (Source:

    Logistic Supply Ship (LSS)

  • provides modular healthcare and residential zones
  • supplies 2,000kW power and drinking water to land

Logistic Support Ship (LSS) will sail at 20knots and accommodate 200 specialists and crew aboard its 165m length. Housing a hospital with radiology chamber, operating rooms, dentist office, and analysis rooms, the LSS can house up to twelve seriously wounded persons.
Equipped with four replenishment stations abeam and one station astern, the LSS will undertake:

  • at-sea repair and maintenance for other ships
  • transport of food, emergency spares, ammunition, freshwater, jet fuel, and diesel fuel to other ships
  • supply of drinking water and 2,500kW power to land
  • rescue operations with its offshore stabilized crane of 30ton capacity
  • base operations of rescue missions via special vessels and helicopters
  • communication, command and control in tactical situations, and dissuasive non lethal defense systems in routine scenarios
  • complex defense system by changing over to an electronic and intelligence war platform when necessary

Fincantieri is a reference player in the naval shipbuilding industry and is among the world’s largest shipbuilding groups. It will provide lifecycle support for the vessel over the first ten years.
Finmeccanica is a leader in Italy’s high-technology sector and intends to take this opportunity to refine its capacity for critical and novel high-technology naval combat systems viz. multifunctional radar, sensors, and multi-sensor integration. With such capable players on board, Italy’s naval expansion can look forward to astounding success.

Surveyor Interceptor Remotely Operated Vessel (ROV)

By | Article, Technology | No Comments

Groundbreaking Development
Survey Interceptor Remote Operated Vehicle (ROV) completed its first commercial mission in March 2015 for the natural gas pipeline operator Gassco. The ROV inspected the external condition of the Knarr Gas Pipeline and the rock berm protection.

Kystdesign built the Surveyor Interceptor ROV for the joint venture (JV) between Reach Subsea and MMT Sweden. The ROV acquires stable data at high speed via a totally new technology used by Survey ROVs (SROVs) that generously cuts inspection cost and time.

Since March 1, 2015, Gassco is the official operator of the Knarr Gas Pipeline. The Knarr Gas Pipeline Joint Venture owns the 12inch pipeline that possesses a technical capacity of 1.7million standard cubic meters per day.

Located about 100km north of Statfjord in the northern part of the North Sea is the Knarr Oil and Gas Field. The Knarr Gas Pipeline will supply gas to St. Fergus, Scotland via the Far North Liquids and Associated Gas System (FLAGS) and the Shell-Esso Gas and Liquids System (SEGAL).

Rock Berm is a rock embankment that prevents the inflow or outflow of material from an area. Underwater rock berms improve the lateral resistance of pipelines to buckling and protect pipelines against possible damage from dragging anchors and hydrodynamic loads created by waves and currents.

Rapid & Reliable Inspection
Inspecting the Knarr Gas Pipeline along 106km of its length, the ROV comfortably traversed water depths of 140-400m and completed the inspection in just 17hours, three times faster than a conventional ROV would. It logged an average speed of 3.33knots and top speed of 4.5knots.

Knarr Oil-Gas Field Location

Deployed from the Edda Fonn, the Surveyor Interceptor was stable throughout the operation. The ROV executed the exercise in one go and acquired high quality data. It swam 4-5m over the pipeline to conduct the multi-beam SONAR survey with a 0.1m grid size to collect a full 3D photomosaic.


  • Fast, Accurate, and Stable with High Resolution\
  • Two Main Inspection Modes and One Manipulator Skid. Main Inspection Modes:
     ‘high fly’ high speed acoustic pipeline surveys
     ‘low fly’ full three camera inspection in known problem areas
  • Can be operated:
     with tether management system
     in free swimming mode
     with special umbilical handling system
Surveyor Interceptor ROV (Source:

Surveyor Interceptor ROV

  • Combines Ultra-Short Baseline and Inertial Navigation aided by Doppler with data acquisition through fiber-optic interfaces and real-time quality control
    Inertial Navigation System (INS) is navigation utilizing dead reckoning that uses computers, rotation sensors, and motion sensors to calculate the direction and speed of movement of mobile objects
    Dead Reckoning finalizes an object’s position based on its previous position and the direction plus speed of subsequent travel
    Ultra Short Base Line (USBL) employs acoustic signals through a transceiver to detect the distance and direction to a target
  • Wide Operational Window
  • Low Pump and Thruster Noise for exceptional data quality. Earlier trials had provided multibeam data with less than 0.4% noise
  • Developed Capabilities of Sensors, Camera, and Lighting for better video and data quality
  • ‘Unlimited Power’ because of no batteries
  • Easy Interfacing with existing survey vessels
  • Compatible with future sensors

After successful offshore trials on Europipe 2 last year, MMT Sweden and Reach Subsea refined the ROV’s cameras and developed a new launch and recovery system capable of operating in sea states of up to 3.8Hs. Earlier trials had also demonstrated an 8knot design speed with high density data acquisition at 6knots when moving close to pipelines.

MMT Founder and Project Director Ola Oskarsson described the 4.5knot inspection speed as a world record and said the Surveyor Interceptor was well capable of reaching inspection speeds of 6knots, 3knots faster than conventional ROVs.

According to Gassco, the Surveyor Interceptor could slash expenditure on submarine pipeline inspection by as much as 30%. These savings will result from the high speed of the ROV and because the ROV is conveniently operated from smaller, cheaper vessels.

It is this potential to massively lower inspection time and cost saving that makes the offshore oil and gas industry eye the Surveyor Interceptor with great interest. Inspection of submarine pipelines is expensive business. The ROV, vessel used to deploy the ROV, ROV technology, and ROV efficiency determine the total cost of inspection.

Gassco is particularly delighted with the Surveyor Interceptor for the company operates the Gas Transport System that delivers Norwegian gas to the U.K., and continental Europe via pipeline of over 8,000km length. And, most of Gassco’s pipelines are located on the ocean floor.

Oil and gas explorers are moving into deeper, more perilous waters to quench our thirst for energy as older fields reach the end of their lifecycles. Pipelines in such water face newer and more lethal threats. Inspecting these pipelines with conventional ROVs may not be technically and financially viable. Thank God, we have the Surveyor Interceptor!

Study: Blue Whales ‘Play Dead;’ Unable to Avoid Ships

By | Uncategorized | No Comments

A Stanford study reveals that blue whales may not have evolved to avoid ships. Their behavioral response? To “play dead,” which makes them even more vulnerable to deadly collisions. Kemplon Engineering takes a closer look at this insightful discovery.

Blue Whales are the biggest of the ocean’s creatures. Their imposing size have kept them from becoming prey for millions of years, sparing them from predatory attacks. Though this helped them survive for a long time, a new study suggests they did not evolve to have defensive behaviors or evasive responses, which would protect them, say, from deadly collisions with the cargo ships now traversing their ocean territory.

In a study directly observing blue whale behaviors with cargo ships – the first of its kind – it appears they have not yet developed an evasive response to this particularly modern threat. Scientists used GPS and dive-logging equipment attached to blue whales to track them, and cross-referenced the information with ship traffic. Their findings indicate blue whales resort to a “startle response;’” essentially, ‘playing dead.’ This reaction makes them vulnerable to getting struck, as it keeps them from diving quickly enough away to avoid collision.

The study is set for a second round of tests, and will be expanded to other species of whales. It is hoped that the information gleaned from the study can improve existing methods of protecting whales from collisions. Currently, methods being employed include the re-routing of ships away from breeding or feeding fields, and setting speed limits.

We at Kemplon Engineering, have been providing engineering services to the maritime community for over a decade. Like many clients we’ve served throughout the years, we have a great respect for our world’s majestic waters and the wonderful and mysterious creatures living within it. While it’s admirable that humanity’s great vessels allow us to take to the high seas, unfortunately, some of our encounters with marine life end poorly for these creatures. We hope that by sharing studies like those mentioned above, we can help disseminate information that would be useful in promoting practices that would allow the sea to be a safe place for everybody.

Cruise Packages & Itineraries For Alcohol Aficionados

By | Article, Technology | No Comments

For many merry tourists, cruise vacations are the time to let loose – not to mention a time to enjoy some moderate amounts of ‘booze.’ For some aficionados, however, alcohol isn’t just a perk, but the main attraction of an itinerary. Luckily for these discerning tourists, there are now several alcohol-themed cruise options for them to choose from.

The American Queen Steamboat Company recently announced plans for a Bourbon-themed itinerary aboard the American Queen, on a nine-day trip between St. Louis, MO and Cincinnati, OH. “The Insider’s Bourbon Trail” includes seminars, lectures and tastings onboard; distillery tour options from iconic producers including Jim Beam; and Bourbon-enhanced menus served daily. Fares start at $2,699 per person based on double occupancy, and tours kick off this summer.

Norwegian Cruise Line is offering all-you-can-drink on short sailings of the Norwegian Sky from Miami to the Bahamas. For passengers of drinking age, alcoholic beverages of up to $11 come at no extra charge. Minors on the other hand, can get unlimited juice and soda. The all-inclusive drink approach is seen as a means of attracting new cruisers interested in short sailings, and to edge out competition that is heating up in the short sailing segment. The offer takes effect in January, 2016.

Un-Cruise Adventures offers four cruises on the SS Legacy geared toward wine lovers. Sailings include onboard wine tasting, activities and presentations, and visits to wineries by the Columbia River. Avalon Waterways, on the other hand, will be catering to fans of craft beer with onboard tasting, lectures and brewery tours on select European cruises.

These are just some of the few and exciting ways alcohol aficionados can merge their passion with traveling. Visit the company websites for more exciting offers and information.

Wartsila’s Innovative WSD 4628 Anchor Handling Tug Supply (AHTS) Design

By | Article, Technology | No Comments

Another Stunner from Wartsila

Wartsila launched a fresh, innovative Anchor Handling Tug Supply (AHTS) vessel design at the Sea Asia Exhibition held at Singapore from April 21 to 23, 2015. The company predicts the design to slash fuel use by up to 20-25% vis-à-vis traditional diesel mechanical four engine systems with a proportional trim down in emission levels.

Sea Asia is the premier maritime event in Asia that witnesses the convergence of a cross section of the global shipping community. Sea Asia 2015 was hugely successful with 16,185 participants from 85 countries. Once again, this importance of Singapore as a leading global maritime center stood emphasized.

Efficient and simple, the vessel uses less fuel and leaves behind lower environmental footprint. It is particularly compatible with large and medium AHTS equipped with a 2-speed gearbox. Such a gearbox is a crucial part of large-medium AHTS for it slashes the cost and complications without cutting back on operational safety.

AHTS vessels tow an oil rig to and from its destination and transport supplies to and from rigs. Sometimes, they serve as Emergency Rescue and Recovery Vessel (ERRV). The winches of AHTS vessels tow oil rigs. Once the rig is in position, the AHTS’ anchor handling equipment drops the rig’s anchor and keeps the rig steady.

Technical & Other Details

Designed for a bollard pull of 180tons, the WSD 4628 AHTS vessel comes with options for 150tons or 220tons of bollard pull. The design boasts of a hybrid propulsion system and a 2-speed gear box built in accordance with American Bureau of Shipping (ABS) and Safety of Life at Seas (SOLAS) norms.

Hybrid diesel-mechanical and diesel-electric propulsion system with 2-speed gear boosts efficiency when operating at fluctuating loads. Directly driven mechanical parts lose less power during transmission at higher loads. Generating power from both main engines and gen-sets with load-optimized engines is advantageous at low loads.

On account of optimization of engines for various loads, this design consumes 17% less fuel as compared to

twin-engine, diesel-mechanical propulsion system. Special hull contours hike fuel savings to 25%. Engine-Load optimization results from:

  • electric boost during high bollard pull mode
  • smooth load sharing with 4 medium-speed engines and mode selection in Power Management System (PMS)
  • electric propulsion during low power mode
  • steaming on both main propellers from one main engine or gen-set

Design Features:

  • Based on Proven Technology
  • Lower Fuel Consumption and Emissions with optimization of engine with loads
  • Economical
  • Safe and Easy Operations via seamless load sharing through four medium-speed engines and mode selection in PMS

Compliant with IMO Tier II exhaust regulations, Wartsila 32 engines were developed because the market required 320mm cylinder bore engines. The engines incorporate latest combustion technology for simple, efficient, and infrequent maintenance.

These engines offer great fuel flexibility, fast starting, high power-to-weight and power-to-space ratios, and high reliability.


Greener and cost-effective shipping is the order of the day and Wartsila has once again delivered the goods. You can hardly expect otherwise from an operator with over half a century of experience.
