Effect of longitudinal bulkheads to longitudinal strength on double hull tanker

Abstract

Abstract The longitudinal bulkhead also plays an essential rule in dividing the cargo hold into several compartments. Besides, the longitudinal bulkhead is one of the construction elements which to strengthen the longitudinal strength of the ship, and it is always used primarily for a tanker. In the present study, the effect of the longitudinal bulkhead is investigated to the longitudinal strength under a vertical longitudinal bending moment. Two ships of double-hull tankers are considered having the same dimension but different for the number of longitudinal bulkheads. The force rotation is applied one side, and the other side is constrained. The result obtained by the numerical method is compared to the analytical method. It is observed that double bulkheads have larger longitudinal strength than a single bulkhead.
