    Vessel Management Services to build escort tug

    Vessel & ROV News // June 15, 2001
    Vessel Management Services, a subsidiary of Crowley Maritime Corporation in the US has placed an order with Marco Shipyard in Seattle for a Protector II class tug, which will be used to escort and assist oil tankers in Puget Sound. The vessel is scheduled for delivery in May 2002.

    The new tug features twin Voith Schneider 32G II/250 cycloidal propellers, powered by two Caterpillar 3608 DITA engines, and a high lift and streamlined hull designed to meet the indirect forces and speed requirements of the tankers operating in Puget Sound.

    The hull is derived from a design for the tug Boxer and was developed by Bukser og Berging, Norway.

    The tug will be 129.5ft long, 45.5ft wide and 24.25ft deep. It will have direct bollard pull of 150,000 pounds and indirect forces in excess of 340,000 pounds at 12 knots.
