A lightweight Launch and Recovery System for an Intervention class Remotely Operated Vehicle. Comprising a winch with integrated Hydraulic Power Unit and an A-Frame with docking head. The ROV is securely handled from above deck to outboard whilst latched into the motion damped docking head. Once outboard the load is transferred to the umbilical winch by un-latching for deployment.

This system has been designed to meet Air-Portability requirements so can be rapidly deployed on a worldwide basis. On arrival at a ship of opportunity mobilisation simply consists of connecting the system to the vessel deck via sacrificial weld down brackets and connecting power. The HPU, Winch and A-frame controls are integrated, and hydraulic connections are made via quick release couplings.

By keeping the design and function as simple as possible but no simpler this system has been designed around the intention of being robust, reliable and easily maintained.
