PROPULSION UPDATES WWW.MARITIMEPROPULSION.COMHT900s for High Speed Crew BoatHamiltonJet reports that four HT900 waterjets were selected by Incat Crowther’s latest project, a ? rst-of-type 70m Catamaran Fast Crew Boat for op-erations in the Caspian Sea oil industry in Azerbaijan. When completed later this year, the vessel reportedly will be the world’s largest high speed crew boat. The new 70m, DP2 class vessel class will feature four control stations, each using Hamilton Jet’s MECS control sys-tem integrating with a DNV DYNPOS-AUTR dynamic positioning system. Powered by four 2880kW MTU engines each turning 900mm diameter waterjets, expected top speed is 36 knots with an ef? cient service speed of 30 knots at full load and 90% MCR. The vessel will be capable of carrying 150 passengers and 14 crew, along with 200 tons of deck cargo, in up to 40 knot wind and seas of 3m signi? cant wave height.
