L27/38 GenSets for TML Heavy Transport Vessels

February 12, 2008

SeaMetric International AS, Stavanger, Norway has during December 2007 ordered a package of 24 MAN Diesel marine generating sets type 8L27/38 for four specialized heavy-lifter transport vessels. Additionally, a Memorandum of Understanding has now been agreed upon between MAN Diesel and SeaMetric International for future identical GenSets to power planned newbuildings. The agreement was officially signed on January 18, at a special ceremony at the Copenhagen DieselHouse. The GenSets ordered (six sets for each vessel) will power a diesel-electrical propulsion and positioning system with four thrusters, specified for SeaMetric’s new TML type heavy-lifter ships. TML is the abbreviation for the innovative Twin Marine Lifter system developed by SeaMetric. Two of the dynamically positioned (DP3 type) heavy transport vessels are 140 m long, with 40 m beam and have a dwt capacity of 25,000 tons, while two are 180 m long with same beam and have a dwt capacity of 35,000 tons. They will have accommodation for 41 persons, a helideck, and will be capable of submersion to -20 meters. As such, they will be capable of transporting very large construction sections, the world’s jack-up drill rig fleet and the majority of semi-submersible drilling rigs as well as topsides modules and other major loads. “By having a DP Class 3 heavy lift system and accommodation facilities, we will not be dependant on anchor handler vessels, tugs, daily helicopter shuttling and accommodation offshore, which will reduce the operational costs significantly. We will also be capable of secure operation in congested areas and above subsea pipelines. The flexibility of use of the base vessels in the heavy transport market will maximize our utilization and therefore improve our potential profitability” says Managing Director of SeaMetric International, Johan F Andresen. The Chinese CNPC, Liaohe Shipyard will deliver the first vessels in the 4th quarter of 2009. The GenSets, which are of the classic MAN Diesel Holeby design with common baseframe for engine and alternator, will be supplied from the South Korean MAN Diesel licensee, STX Corporation during 2nd and 3rd quarter of 2009. The ships’ GenSet package is specified as 6 x 8L27/38 – in order to meet the special operating demands of each of the four newbuildings with accumulated GenSet outputs of 15.840 kW (21.500 BHP) mechanical power.
