Elliott Bay Develops New

Tug Design For Crowley

Elliott Bay Design Group (EBDG), a Seattle-based naval architecture and marine en- gineering firm, has developed a new ship escort and assist tug design for Crowley Marine

Services, Inc., of Oakland, Calif.

Crowley plans to build two of the new-generation tugs, stationing one in Long Beach, Calif., and the other in Puget Sound; with deliv- ery anticipated in the fall of 1996.

The new boats will feature ABS- classed hulls and machinery, ABS

Class 1 firefighting capability, and

Voith-Schneider 36GII/200 propul- sion units. The design features special acoustic insulation for crew protection and comfort, and the main decks inside the deckhouse are to be fitted with floating floors, with floating bulkheads and over- heads in the deckhouse staterooms.

The 120-ft. (36.8-m) steel tugs will oper- ate at 14 knots, each propelled by a pair of

Caterpillar 306 diesels, rated at 2,750 bhp, driving the Voith-

Schneider units. "These will be truly state-of-the- art ship handling and escort tugs," said Crowley Vice President of

Engineering Maynard Williams; "based on research and experience, we've very carefully thought out their size and power to match their mission."
