pounds per square foot on the tank top, 350 on the 'tween deck and its hatch covers, and 332 psf on the main deck and hatch covers. Cargo-handling gear comprises two Hagglund 20-ton cranes, one 8-ton boom, and two 5-ton booms. The Hagglund cranes are of the automated tandem type, which enables one operator to control both cranes simultaneously, there- by doubling the lifting capacity when necessary. Tandem crane operation is coordinated and syn- chronized by a mini-computer.
