Moment to Change Trim - an overview ScienceDirect …
Web5 jun. 2024 · 1. On a ship of W 5000t , GM 0.3m, 20t was shifted transversely by 5m. Find the list. Solution: W = 5000t, GM = 0.3m, Weight shifted (w) = 20t & d= 5m Listing moment = (20 x 5 ) = 100tm Tanθ = ( Listing Moment) /(W x GM) = 100/(5000 x 0.3) = 3.8 degree. 2.

MCTC= ∆×GML 100×LBP CoT= Trimming Moment MCTC WebMoment to Change Trim 1 cm (MCTC) Now we have seen that to change the Trim we need to move weights in the fore and aft line of the ship. This then brings about a moment, and the moment required to change the trim by 1 cm is given by: MCTC = (W x GMl) / 100 x L.
