Abstract

Weights engineering feeds into hydrostatic trim and stability analysis and hydrodynamic analyses of many sorts. It is an important task that requires attention to detail and hours spent carefully reviewing drawings and manufacturers cut sheets to develop data at the necessary level of detail. What do you do when the ship was built far in the past and few or no drawings exist? What if there are a few drawings and references but they conflict on critical details? Will we ever be able to do an adequate weights analysis? This paper describes several such analyses and the detective work and re-engineering that has gone into developing reasonable weights and centers information for these historic vessels. These analyses were used to support sinking analyses in several cases and the problem is significantly different for a wooden vessel than a iron or steel vessel. The just-submerged analysis is significantly different from the surface analysis. Many tricks of geometry and integrating the results from different software can be used to further the understanding of the missing data.
