RECOMMENDED MAXIMUM VALUES OF METACENTRIC HEIGHT FOR SHIPS CARRYING TIMBER DECK CARGO

The aim of this paper was to develop a set of values for maximum allowable metacentric height for vessels loaded with timber deck cargo. The total required restraining force on the cargo was calculated for various maximum roll angles and rolling periods. It was found that rolling periods of 25 seconds or more limit the initial stability of a vessel sufficiently to reduce excessive forces on the cargo. Based on these data, the author developed a table of maximum allowable metacentric heights for vessels of various beams loaded with timber deck cargoes. The maximum values shown will produce a rolling period equal to or greater than 25 seconds.
