LARS (2)

The Okeanus launch and recovery systems (LARS) are designed for dependability, ease-of-use and safe handling of subsea equipment in the harshest environmental conditions. SOSI handling systems have an exemplary track record for safe and efficient operation in high sea state and are designed with the operator in mind.

The fully integrated system, designed and built to launch and recover a free-flying ROV, contains a winch / level wind assembly, self-erecting A-Frame, docking head / over-boarding sheave assembly and electro-hydraulic power unit, all mounted to a single skid. This innovative design allows the entire system to be placed into an ISO flat rack for ease of transport and deployment. To further facilitate rapid mobilization, the ROV is stored on the skid assembly during transport.
