As the month of April comes to a close, Kemplon Engineering looks back on some of the most compelling maritime industry developments of the last 30 days, in this edition of the Monthly Maritime News Roundup:

One of the most important humanitarian issues unfolding in our time is the European Migration Crisis – where hundreds of thousands of irregular migrants from North Africa and the Middle East flee conflict or poverty from their homelands for a better life in Europe. Many of them make the journey by treacherous sea routes, on overcrowded or barely sea-worthy boats. Read More

Waterjet technology utilizes water that travels at extremely fast speeds and very high pressure to erode a material being cut. It is a basically a six-process technology that involve a high velocity stream of rough particles suspended in a stream of extremely high pressure water. A big assortment of heat-sensitive, delicate or very hard materials is used in machining. Sintered boride usually comprises the nozzles. The technology also produces no damage caused by heat to the work piece edges and surface, and a taper of less than one degree on most cuts. Lastly, this technology shows that the distance of nozzle from work piece affects the size of the kerf and the material’s removal rate. Read More

Global Calamity in the Making

Transfer of aquatic invasive species is among the prime threats to the long term health of our oceans. And ballast water operations are the chief instrument of such transfers. These species leave their toxic imprint on the environment, economy, and public health.

More than a decade after the International Maritime Organization (IMO) first introduced the Ballast Water Management (BWM) Convention 2004, the convention remains a paper tiger for want of sufficient number of signatories. Read More

Types of Metal for Custom Metal Fabrication

By | Article, Technology | No Comments

We are fortunate to be endowed by nature with the most useful metals we can get our hands on. As early as the previous century, the sue of metals have changed the way we live, paving the way for more production of maritime transportation by using a variety of metals. We have naval ships, pressure vessels, cargo ships, leisure yachts, commercial boats and more that help make our lives easier. As for the types of metals that are commonly used in fabrication, this list shows you the importance of three of the most common metals used in shipbuilding. Read More

Copper alloys are used in shipbuilding mainly because of its ability to resist corrosion by salt water or salt-laden atmosphere.

Copper and copper alloys are largely used for shipbuilding are used to the greatest extent, specifically in engine and boiler rooms.  They are also utilized in cooling systems, evaporators, low temperature steam lines, feed heaters, pumps, valves, and coolers. The electrical equipment in a ship that consist of generators, lighting, electric motors and communications systems depend largely on copper and copper alloys to function properly whether on land or water.

For Venturing into Icy Wilderness

Cammell Laird will build a cutting edge polar research vessel for the UK Natural Environment Research Council (NERC) at Birkenhead Shipyard. Designed by naval architects Houlder, this will be the first UK-built polar research ship with a helideck.

After the steel cutting ceremony slated for late 2016, the vessel will go operational in 2019. It will replace NERC’s two existing icebreakers viz. the RSS Ernest Shackleton and the RSS James Clark Ross. Read More

First Methanol-Powered Tankers Set for Delivery this April

By | Marine News | No Comments

Waterfront Shipping Company Ltd., Mitsui O.S.K. Lines, Ltd., Westfal-Larsen Management, and Marinvest/Skagerack Invest will be welcoming seven advanced, clean-burning, fuel-efficient, 50,000 dead weight tonne vessels to the sea later this month.

This is first-of-its kind vessels capable of running on methanol, gas oil or fuel oil. This kind of technology will surely lessen the emissions while offering ship owners an efficient, feasible and convenient fuel alternative. Methanol is a biodegradable marine fuel that lessens smog-causing emissions like particulates, sulphur oxides and nitrogen oxides.

A Monumental Engineering Marvel

Located in the vicinity of and across the confluence of the Gulf Intracoastal Waterway (GIWW) and the Mississippi River Gulf Outlet (MRGO), is the 1.8 mile long Inner Harbor Navigation Canal Lake Borgne Surge Barrier (IHNC-LBSB).

Built in response to the carnage unleashed by Hurricane Katrina, the purpose of this barrier, lying about 12 miles east of downtown New Orleans, is to protect parts of New Orleans from the deleterious effects of a storm surge.

Focus on the Human Element

Researched and developed by the United States Coast Guard (USCG) over a span of a quarter century and successfully tested by the USCG and the US Army is the Crew Endurance Management System (CEMS), a comprehensive instrument for dealing with sailor’s fatigue.

But, just how serious is fatigue in the maritime world? For one, the USCG blames human errors for 75-96% of maritime casualties. And the same USCG also identifies fatigue as the paramount agent of human error.  Read More
