Bollinger Marine Fabricators on Lytal Ashley - an oilfield supply vessel (OSV) for Lytal Ocean. In addition, a contract has already been formalized for a nearly identical sistership Lytal Andre, which is scheduled for delivery in April 2001. Both vessels will measure 146 ft. (44.5 m), each with a 36-ft. (10.9 m) beam and a depth of 11 ft. (3.3 m) Normal operating draft will be 10 ft. (3 m) and speed is expected to be 12.5 knots. Bollinger's engineering department designed the vessels to meet and exceed new regulatory requirements, which is less than 100-gt and less than 500-gt registered tonnage. Two Detroit Diesel engines developing a total of 1,400-bhp will power each OSV. They will drive 70-in. diameter by 67-in. pitch, four-blade Bird Johnson propellers through Twin Disc gears.
