Penilaian Performa Ketegaran Kapal BMA-10 Pada Tahap Initial Design

Abstract

Ships dynamically depend on hull behavior and response to operational conditions. At the time of operation, ship body will experience movement caused by the ship itself (maneuverability) or from external factors (seakeeping). External factors, for example in the form of bad weather that can cause large waves can endanger the safety of the ship if the ship is unable to respond to the waves. BMA-10 operating in waters with dynamic wave characteristics require seakeeping assessment so that they are technically feasible and can be a reliable public health service facility by taking into account the comfort of the crew and patients. Physical rigidity performance assessment uses an empirical approach that refers to the parameters of the main dimensions, hydrostatic characteristics, variations in heading angles and water characteristics. The physical rigidity aspect in accepting external forces is analyzed in 5 (five) variations of heading angle 0o , 45o , 90o , 135o and 180o . The biggest heave condition is at 135o . Greatest pitch condition with a heading angle of 180o and a roll condition at a heading angle of 135o . From these conditions, it becomes a concern for ship operators to be alert and pay attention to the direction of arrival and wave height so that the ship when operating remains comfortable to use.
