Analysis of Stability, Resistance, and Seakeeping Accord to Dimension and Form of Fishing Vessel 10, 20, 30 GT

Abstract

Fishing vessels used to catch resources from the sea has to pass some of the regulations from International Maritime Organization for sea-worthiness of the vessel especially about stability, resistance to acquire the highest velocity, and the vessel’s motion. This research discusses the effect of the vessel’s dimension and the hull shape by using the stability standard from IMO.The result shows that the ratio of the B/T which meets the stability criteria is 2.50 with the ratio of KG/H of the vessel is 0.65, with the assumption that the KG and H of the vessel are more than 0.70. Whereas if the resistance ratio B/T is big, the resistance for the vessel will be relatively smaller. In terms of the vessel motion, a vessel with a V-type hull will better than a U-type hull in seakeeping.

The Effect of Trim on Stability and Seakeeping of Tanker, Container, and Bulk Carrier

“…To calculate the stability used each ship load case conditions which IMO Stability Criterion A.749 (18) Ch.3 become standard calculate, that will be shown on Table 4, and table 5 will show the seakeeping criterion [4].…”

“…The shape of a ship hull is also a huge factor in determining ships stability and seakeeping performance, also can be affected the ship resistance factors. Meanwhile the ratio more higher between draft and breadth of ship, the stability will be increased [4].…”

Investigation of Seakeeping Performance of Trawler by the Influence of the Principal Particulars of Ships in the Bering Sea

“…Three categories were defined according to the results considering various Froude numbers, loading conditions and the wavelength to the ship length ratio. Manullang et al (2017) discussed the influence of the ship dimensions and the ship hull shape on the ship motion responses in the following wave, beam wave and head wave.…”
