Stillwater River

Stillwater River is the first advanced high-speed crew boat using the SWATH (small water plane area twin hull) technology.

The all-aluminum vessel was designed specifically as a crewboat for operation in the Campos Basin offshore Brazil with a capacity for 250 passengers.

Owned by TRICO Marine

Services, Stillwater River is 120 ft. in length, and operates at a loaded draft between 11 and 12 ft. It is particularly suited for high-speed transportation of offshore rig per- sonnel to and from platforms in the rough waters of Campos Basin.

The SWATH design produces slower motions, less likely to cause passenger discomfort due to the fact that the portion of the hull that gives displacement, rides below the surface of the ocean.

During sea trials, the vessel reached a trial speed of 31 knots.

Power is provided via a pair of

Allison 501 KFS gas turbines, which produce 9,600 total hp.

Reduction is provided through a pair of custom-built Philadelphia

Gear Model HP-25 gearboxes with 28:1 ratios, that also furnishes power for an assortment of other

Jeffboat's Santa Elena

Jefiboal lu tened Santa Elena. Designed to carry a crew of 16 for shallow draft operations, the vessel was built by Jeffboat for American Commercial

Line's South American operations. The vessel may operate on the Ohio and Mississippi Rivers for sonic period of time before being shipped to

South America.

Power is provii d to

Haley reduction gears and 100-in. live bladed propellers in custom fab- ricated Kort Nozzles. The boat has two 150-kW generators driven by

Detroit Diesel 8V-71. engines. Fuel capacity is 70,000 gal. Water capac- ity is 18,000 gal.

The boat has a design draft of 8.25 ft. and the maximum height is 42.5 ft. above the water-lino. Outfitting includes Kuruno radars and fathometer, Zeeland swingmeter and autopilot. Xabrico winches, and a Scholellhom Albrecht capstan.
