(CMS) has won a 10-year contract from Alyeska Pipeline Service Co. to design, build and operate two 10,192-hp tractor tugs, specially designed for tanker escort opera- tions in Valdez Harbor and Prince William Sound, Alaska, The 153 x 48-ft. (47 x 15-m) tugs will feature Voith Schneider twin cycloidal Model 36 GII/269 propulsors driven by Caterpillar 3612 turbocharged four-stroke diesel engines. Both vessels will be outfitted for tanker escort services, ship han- dling, firefighting, emergency response and spill response capa- bility in Alaskan waters. Design features include welded steel construction, transverse framing, wing tanks and ice belt- ing. "We had a well-founded strategy that has involved four or five years of research and develop- ment. The design for the Prince William Sound tugs was built from the keel up, so there is a total integration of design fea- tures which permits seamless transitions during the perfor- mance of the varied missions of the boat," said Gary Faber, CMS vice president, Operations. Upon their delivery, the new tugs will be dedicated to serve as part of Alyeska's Ship Escort/Response Vessel System (SERVS), escorting laden tankers as they depart from the terminus of the Trans-Alaska Pipeline at Valdez and proceed southbound through Prince William Sound.
