Trimaran Preliminary Structural Design Procedures for a Large High Speed Sealift Ship

by John C, Daidola, Andrew Arnold, and Michael J. Imbesi

Structural design characteristics for a large high speed trimaran sealift ship are determined using the Lloyd’s Register Trimaran Rules. These are compared to characteristics determined utilizing a more traditional naval approach for monohulls and also with a combination of naval and American Bureau of Shipping commercial criteria. The analysis also considers additional approaches for determining transverse hull loads and wet deck pressures by alternative procedures.
