Development of a Twin Stern Ramp Launch & Recovery System for Rigid Hull Boats on a Multi-Role Naval Vessel

Deployment of fast response craft at sea is essential for a range of littoral missions including maritime security and search-and-rescue. Traditional launch and recovery of fast response craft like rigid-hull boats (RHB) employ side davits and cranes. In light of evolving technology, multi-role navy ships like the Republic of Singapore Navy’s Independence-class Littoral Mission Vessel have incorporated stern ramp Launch and Recovery Systems (LARS) to overcome the slower deployment times associated with cranes and davits. Twin stern ramp LARS are suitable for requirements of multi-RHB operability, while achieving faster craft launch and recovery with fewer deck crew required. The paper identifies the design considerations, safety considerations, and qualification process for twin stern ramp LARS.
