Stability Calculations for ARAPAHO Feasibility Demonstration,
Abstract
A review was conducted of ARAPAHO as it would be configured for the upcoming feasibility demonstration aboard C5-S-73b (Export Leader) containerships, as requested. This review has included contact with the U.S. Coast Guard, the Maritime Administration (MARAD), the Norfolk International Terminal, and a visit to the ARAPAHO system on site at NAEC in Lakehurst, N J. The C5-S-73b ships will be compatible with ARAPAHO for the feasibility demonstration. Visibility for the ship's officers from the navigation bridge will be adequate, as the entire ARAPAHO system will be aft to the forward house. Deck area and load capacity are sufficient for the intended application, and stability is satisfactory. Metacentric height should be approximately 8.5', compared to the minimum requirement of approximately 4.0'. It is anticipated that the mean draft of the ship during the demonstration will be about 15'-2 in, with a trim of 9'-1 in. by the stern, which provides a trim angle of less than 1.0 deg. It is concluded that, as far as naval architectural aspects are concerned, the ship 'Export Leader' is matched to the purpose intended and the demonstration should be technically sound and effective.
