Rapido Gee, a 42m steel monohull utility vessel, has been delivered and is currently in transit to the Middle East. The vessel will be operated by Rashied Marine Services in the service of offshore platforms. Designed by Incat Crowther and built by Strategic Marine, Rapido Gee is a further development of the design used for the 10 vessel fleet of Infield Utility Vessels delivered by the shipbuilder. In response to calls for construction simplicity, Incat Crowther reengineered the vessel with mild steel used in the hull in place of the original high tensile steel.

The Forum looked at a broad spectrum of topics concerning container shipping including: stowage and lashing, the potential for LNG vessels and bunkering, trends in the liner markets, high tensile steel and thick materials for ship building, pilotage and maneuvering XXL container ships in the Hamburg harbor and the advantages of having an Emergency Response Service. Some 50 representatives from the container industry met with GL experts at the Container Ship Forum, to hear the presentations and participate in informal discussions.

Ever Lambent Named in Korea.

The CMA CGM Group has just acquired another 18,000 new units, bringing its eco-container fleet to nearly 140,000 teus. For many years, the Group has attempted to minimize its impact on the environment through the following initiatives. Since 2005, the Group has been offering containers with bamboo floors. The result of a collaboration between CMA CGM and one of its main customers, these containers meet two objectives: to limit the use of wood from primary forest and to improve the technical qualities of the containers. Today, more than 10% of the Group’s fleet is equipped with this type of flooring. What’s more, the Group is currently testing new synthetic resin flooring.

Technical proposals for the shipment of natural gas under compression rather than in the refrigerated, liquefied state have surfaced from time to time over the years, but have received a lukewarm response from the marine industry. The considerable cost of the shipboard containment methodology has been a major stumbling block. Now, a Canadian engineering contractor has come up with an altogether more economic solution to the cargo carrying needs of compressed natural gas (CNG), and pitched at relatively short-distance sea transport applications. Instead of the prohibitively expensive pressure bottles that have earlier been central to CNG transport concepts…

Leading international classification society Bureau Veritas and French shipowner Services & Transport have developed an Ecomax tanker design intended to address all the major causes of large oil spills. The Aframax design has two independent engine rooms, power supply systems and steering gear, increased hull scantlings, reduced high tensile steel content, duplicated navigation equipment with off-track monitoring and full inerting of all ballast spaces. The Ecotanker design is based initially on an Aframax vessel, but studies have also been done for larger and smaller vessels. same. The possibility of machinery and systems failure is addressed by duplicating the engine rooms, stern tubes, propellers, steering gears and rudders.

"While smaller oil spills are getting less frequent, the occurrence of large spills due to tanker accidents is remaining constant," says Philippe Anslot, technical director of services & transports. "When we looked at the underlying causes of those spills we saw that the four main factors were machinery failure, navigation error, fire and explosion and hull damage.

Mark van Schaick Marine Services is a relatively new company, based in Schiedam (Port of Rotterdam) specializing in crankshaft repair, repair of engine and industrial parts, technical consultancy, and marine and industrial spare parts. The company has capacity at its workshop for grinding crankshafts up to 20 ft. (6 m) on a lathe built by Naxos Union. As a result of a co-operation with Mitchell Shackleton in the U.K., crankshafts up to 39.5 ft. (12 m) can be repaired. Every possible kind of crankshaft can be checked, ground, polished, straightened, hardchrome-plated and hardchrome-ground. If a client requests, the company will undergo inspection by certification and classification societies. Repairs can also be carried out on turbine parts, engine blocks, connecting rods and pistons.

Continuity is a valuable asset in the marine field, especially so in relation to the most essential products pivotal to vessel design and operation. The diesel engine producers' adeptness at enhancing existing, successful designs at intervals through power and performance upgradings is a prime example of the development potential built into ships' machinery, making for longevity of the series involved. The ensuing continuity of the product line offers practical benefits to the client market and also to the licensors and manufacturers, given the huge investment costs entailed in developing entirely new engines and putting the requisite tooling in place.

Innovation on the tanker front comes from many venues, and one of the latest — the Ecomax tanker design — is offered from the minds and experience of a pair of French companies, classification society Bureau Veritas and shipowner Services & Transport. The new Aframax tanker design is intended to address all the major causes of large oil spills, and features two independent engine rooms, power supply systems and steering gear, increased hull scantlings, reduced high tensile steel content, duplicated navigation equipment with off-track monitoring and full inerting of all ballast spaces.

To great fanfare, Iñigo Tapias, the new 138,000 cu. m. liquefied natural gas (LNG) carrier was launched on January 29 by IZAR's Sestao yard in Bilbao. The ship — standing in testament to the 1,213 workers at Sestao who physically made the ship a reality as well as the underlying strength of the IZAR company — is a highly significant one for many reasons, both technical and business. The 933-ft. (284.4-m), 19.5 knot ship embodies the hopes of a shipbuilding nation that is seeking to re-establish its presence in the LNG niche that it has not occupied for more than three decades, as the production of gas ships generally lays in the hands of Far East builders today.

I am a naval architect, and when I, in the 80's, as a shipowner, was approached by that class society, now trying to pose as leading the way to more robust ships, with the proposition that we should reduce scantlings in our newbuildings by using more high tensile steel, I refused. company, but we got the safe and robust ships we wanted.

Europe's fledgling offshore wind power industry has produced an order for an entirely new breed of vessel designed to transport and position wind turbines. U.K.-based engineering firm Mayflower Energy has contracted one such vessel from Shanhaiguan Shipyard in northern China on the strength of emerging demand for alternative, 'clean' energy sources. U.K. government plans call for 1,300 new 2-MW offshore turbines to be brought on stream over the next 10 years, and other littoral European countries have formulated large-scale projects for wind power generation systems. The perceived environmental acceptability of harnessing wind power for electricity generation is a strong motivator for the evident political approbation.

While catamaran and multi-hull vessel technology is increasingly being explored for its potential in high-speed military and logistical support applications, Rolls-Royce has unveiled a proposal for a fast naval sealift ship based on a monohull RoPax ferry design. The impulse for developing a vessel type with that rare combination of exceptional speed and relatively high payload capacity originates from the changing emphasis in military support requirements, not least the deployment of rapid response forces to distant areas at short notice. The project has also been driven by a general trend towards faster combatants and the complementary need for a faster speed of back-up and replenishment. The Rolls-Royce proposal entails a 4,000-dwt vessel of 581 ft.

Representing an important milestone for U.S. commercial shipbuilding, the delivery of the 141,740-dwt Polar Endeavour signaled the unfolding of a major new chapter of investment in the fleet dedicated to coastwise transportation of Alaskan crude oil. Giving first form to the Millennium concept, the tanker has been purpose-designed for trade in the world's most environmentally-sensitive waters. While Polar Tankers' main requirement of the Millennium-class is to ship crude to Puget Sound from the Trans Alaska Pipeline terminal at Valdez, the series is also suited to the needs of the traffic to California and Hawaii. The program had been implemented in 1997…
