Chouest contracts three 145-ft boats from Bollinger
Gary Chouest, president of Edison Chouest, said, "We look forward to building boats with a yard which has quality people, and products. It is also always nice to build boats with great friends!"
Vessels will meet new regulatory standards and will be less than 100 GT (U. S. Reg.) and less than 500 GT (ITC) registered tonnage. Each vessel will be 145-feet long with a 36-foot beam and maximum draft of 11.5-feet. Normal operating draft will be eight feet.
The first vessel will be powered by two Cummins KTA-38MO diesel engines rated @750BHP at 1600 RPM. The Cummins package will drive Bollinger 72 inch by 57 inch, four-blade, stainless steel propellers through Twin Disc MG5301 reverse/reduction gears with a ratio of 4.96:1.
The second and third vessels will be powered by two Caterpillar 3508B-diesel engines rated at 855 BHP at 1600 RPM. They will drive 72 inch, four blade NIBRAL propellers through Twin Disc MG 5301 reverse reduction gears with a ratio of 4.96:1.
International Marine Systems Hydraulic steering will be installed at two pilothouse stations and a 272 HP Schottel, STT-110 bow thruster will aid steering on all three vessels.
The engines feature a "package" that meets new IMO (International Maritime Organization) emission standards.
The boats' electrical power will be provided by two Cummins 6CTA8.36 diesels driving two Cummins 99 KW generators with direct drive liquid mud pumps off of the generator engines thereby eliminating belt systems.
Each of the new Chouest OSV's will be equipped with 4 liquid mud tanks and 2 methanol tanks.
Their large 95 foot by 32 foot aft decks will be able to carry up to 390 long tons of cargo. Their crew/passenger decks will emphasize crew comfort with larger staterooms and living quarters with extra sound proofing and carpeting and 20 tons of Carrier air conditioning and 25 kW heating.
Delivery of the first vessel will be summer 2002 with the remaining vessels following in October and December 2002. Contract terms were not disclosed.
