The SR-Endurance 7.0 is a general purpose semi-autonomous aluminum workboat designed to meet the needs of numerous coastal and offshore operations. The SR-Endurance 7.0 meter workboat was initially designed to provide a cost effective and low noise deployment platform for towed hydrographic and research sonar systems, as well as research and development of dipping sonars. The battery powered electric propulsion system provides a quiet towing environment with extended endurance when coupled to the diesel generator. The diesel generator operates between periods of low noise operation to recharge the battery system. The series hybrid propulsion system is an established configuration utilized in terrestrial busses and various marine vehicles.

The SR-Endurance 7.0 has diesel electric hybrid propulsion, an automated A-frame boom type launch and recovery system (LARS), which can be operated as a manned or unmanned vessel. The level of autonomy for the unmanned system can be configured for the task at hand. Autonomy levels range from remote control (no intelligence/man in the loop), basic (minimal intelligence), mature (manned oversight), and advanced autonomy (man out of the loop/full automatic mission implementation).

The LARS utilizes an aluminum electric winch, and instrumented overboarding sheave, a constrained docking head with home sensor, and an instrumented boom assembly driven by a closed loop hydraulic unit.

In addition to the sonar deployment and towing capability, a 6 inch pipe flange is provided under the hull for hull mounted sonar systems. A sealed cable way to the deck provides a simple method for customer integrated sonars.

The LARS system is sized to allow deployment of small ROV system such as the SAAB Seaeye Falcon. The winch pull force, boom lateral and vertical clearance as well as the clearance over the transom are designed to accommodate the ROV deployment.
