46 Maritime Reporter & Engineering News ? AUGUST 2013 duel fuel diesel generator engine system. Four Wärtsilä-Hyundai diesel engines in each ship, fuelled either by gas or fuel oil, will power two propulsion motors driving a single Þ xed pitch propeller. Registered in the Marshall Islands, the ships will operate on charter to Gazprom and Statoil.The ships? bridge design complies with LR?s NAV1 notation, which con Þ rms the bridge layout and level of equipment are suitable for safe periodic operation under the supervision of a single bridge watchkeeper. The accommodation ar- rangements fulÞ ll the new requirements in accordance with the Maritime Labor Convention (MLC, 2006).Another Korean yard, Daewoo Ship-building & Marine Engineering (DSME), has been active as usual, and recently signed a contract with U.S.-based Atwood Oceanics, for the con- struction of a drillship, an option of last year?s contract with a value of approxi- mately $570m for delivery at the end of 2015. The drillship is a DSME-12000 type drillship which was developed using DSME?s own technology. It is able to drill down to a maximum of 12km in water up 3,600m in depth and will pos-sess dual derricks so pipe assembly work and drilling operations are possible at the same time. This will increase its effec- tiveness and reduce working hours by 25% when compared to a single derrick system.Atwood Oceanics has placed orders for drillships consistently since the Þ rst con- tract in January 2011. This latest contract puts DSME?s se- cured orders for 2013 at 14 vessels and offshore platforms worth $4.7 bil- lion. By earning 85% of the contracts won through offshore projects, DSME strengthens its competitiveness in the offshore market. DSME also recently delivered the Þ rst electrical LNG carrier to be ordered by Maran Gas incorporating induction-based electric propulsion motor technol-ogy from GE?s Power Conversion busi- ness. The Woodside Rogers was built at DSME?s shipyard near Busan, complet- ed sea trials in late April and was deliv- ered to Maran Gas on July 1. It is the Þ rst of seven LNG carriers incorporating the GE power and propulsion technology that Maran Gas has ordered from DSME for delivery between now and 2015. For the Woodside Rogers, GE supplied a complete system comprising of four 9.85-MVA generators, main and cargo switchboards, four transformers, two converters, two 13.26-MW motors and remote control. GE also provided project management, system and equipment en-gineering, commissioning and assistance for sea and gas trials.The electric drive system for the Wood- side Rogers is powered by tri-fuel en-gines that run on natural gas, marine diesel gas or heavy fuel oil. The ship op- erator can choose the mode according to current prices of the different fuels, mak- ing the system very cost-effective. In ad- dition, the layout of the tri-fuel engine provides a high level of redundancy, which improves the safety of the carrier avoiding off charters. Fuel consumption and emissions also are lower. Vantage ordered its Þ fth drillship, Co- balt Explorer, to be built at Daewoo for an August 2015 delivery. The company will issue convertible debt to fund the initial $60 million yard payment. Cobalt Explorer will be one of the highest-spec drillships in the global ß eet. To that end it will be able to drill in 10,000 ft. of wa-ter and to depths of 40,000 ft. It will be equipped with two seven-ram BOP?s and will be capable of dual-activity opera-tions. The Cobalt is the fourth rig VTG has ordered from DSME, and it will have the same equipment on board as its sister ships Tungsten, Titanium and Platinum Australian shipyard Incat Tasmania Pty Ltd. is building for Buquebus what is claimed to be the world?s fastest high- speed ferry, Francisco, which is powered by Wärtsilä?s axial waterjets and fueled by liqueÞ ed natural gas (LNG). The ves- sel has passed its sea trials and is now ready to commence commercial opera-tions.The ferry is built to transport passen-gers and cars between Uruguay and Ar- gentina.According to Incat, Francisco is now the fastest ship in the world. While there are speed boats that can surpass 58 knots, there is no vessel aß oat that can reach these speeds and that is able to carry 1,000 passengers and 150 cars. The ferry will have an operating speed of 50 knots, and in crossing the River Plate (Rio de la Plata) at high speed, the ferry will be able to viably compete with air trafÞ c between Uruguay and Argentina. Dubai-based Grandweld has now com-pleted its move to its new ultramodern ship construction site on the premises of Dubai Maritime City, and with that the shipyard recently celebrated a steel cut-ting ceremony to signify the commence-ment of the construction of the Þ rst of four new class Crane/Workboats for Ku- wait Oil Company (KOC)The contract was signed in February 2013, to design and build a series of four heavy-duty Crane / Workboat class ves- sels for Kuwait Oil Company. These vessels are powered by two 1068kw main engines driving ASD Thrusters. They are designed to under- take tasks such as lifting and moving heavy equipment, oil pollution control, SBM hose handling, FO/FW supply, and other related duties. Each vessel comes with a crane capable of lifting 20 tons at 10 meters radius.Portugal?s Lisnave, Setubal has re-cently carried out repairs on-board EMAS? 5,096 grt self-elevating lift boat Lewek Leader. The main work scope for this project was to replace the lower part of one self-elevating leg, which has suffered cracking, with new leg sections (four) which includes spud can with 10 ft. The new leg, which will measure 97.5 x 3 m, and spudcan was prefabricated in U.S. and installed at the Mitrena ship-yard. The Lewek Leader is a self-elevat- ing lift boat measuring 56.4 x 44.2 x 6.9 m classed by ABS. It is self-propelling and self-elevating, with a large deck area and high capacity cranes (two 181 tons at 9.10 m). The unit, which has accom- modation for up to 160, is designed for use in shallow waters up to 65 m. Its propulsion machinery comprises three 1,100 kW azimuth thrusters, a 440 kW bow thruster. Lisnave also completed general repairs to the 13,688 grt seismic research ves-sel Ramform Sovereign, owned by Nor- way?s PGS. amform Sovereign was built in 2008 in Langsten, Norway and has re-The Shipyard EditionHyundai Heavy Industries Hyundai Heavy IndustriesDSMEDSMEArctic Aurora, the second of two new ice-class LNG carriers for Dynagas built by Hyundai Heavy Industires.
