| dc.description.abstract | Sri Lanka Naval fleet consists of 55 Fast Attack Craft (FACs) belonging to the Sri Lanka Navy (SLN) and Coast Guard which are propelled by water jets, conventional V-drive propulsion systems, and Articulated Surface Drive (ASD) powered by twin diesel engines. Recently, the drop in speed of FAC’s has been a challenging problem to SLN. The objective of this research is to find out the reasons for the speed drop of FACs, and the effect of hull cleaning/routine underwater maintenance as a solution. The research mainly focused on gathering information related to speed with RPMs and observing changes to the hull, and finally modelling of a similar shaped hull and analysing effects on speed due to the changes in the hull form. | |
