ASIE DUA Halter Marine The second of Halter Marine's new high-speed Sea Shuttle class crewboats was delivered last year to Asie Crewboats SDN BHD of Kuala Lumpur, Malaysia. The all-alumi- num Asie Dua, like her sister vessel Asie I, is 112 feet long with a 25-foot beam and 11-foot depth. Her spa- cious 60- by 20-foot aft deck can carry up to 80 long tons of cargo together with 15 tons of consuma- bles below deck. She can accommo- date 55 passengers and has quarters for a crew of five. Asie Dua is powered by four De- troit Diesel 12V71TI diesel engines developing a total of 2,040 bhp. They drive two Federal propellers through Twin Disc MG514 reverse reduction gears with a ratio of 2.5:1. An interesting feature of the new vessel is her 1,200-square-foot aft deck, which is completely level and not cambered as on many other ves- sels engaged in similar work. Another design innovation of the Sea Shuttle crewboat is the place- ment of the passenger compart- ments. All are above the main deck and away from the engine room. This reduces noise and allows rig crews to arrive fresh and ready for work. Passenger well-being is also enhanced by large windows provid- ing excellent visibility and lighting of the spacious, airy passenger com- partments. The extended visibility is carried through in the pilothouse high atop the passenger compartment, where the captain has a 360-degree view through extra-large windows.

The Asie Dua was built at Halt- er's Chalmette, La., division, one of six shipyards operated by the com- pany in the Southeastern United States. Halter builds more than 30 different types of vessels, and is the world's largest builder of supply boats for the offshore oil and gas industry. Halter was purchased re- cently by Trinity Industries, Inc. of Dallas. ASIE III Fjellstrand Fjellstrand A/S of Omstrand, Norway, recently completed the 96- passenger crewboat Asie III.
