One vessel, three solutions and multiple applications.
The Accession USV is a unique solution for the emerging Unmanned Surface Vessel (USV) market offering one vessel design at three different vessel lengths. Specifically designed to meet the challenges of surveying in the nearshore and offshore environments this vessel has a base design length of 3.50m with optional additional hull sections to create 4.25m and 5.00m variants.
The modular design of the Accession USV follows Unmanned Survey Solutions (USS) core desire to make surveying easier, safer and cheaper compared to manned vessel solutions.
The USS team created her specification from in-depth knowledge and experience of operating sonars and sensors for survey operations. Our Naval Architect then applied extensive sea keeping knowledge and commercial MCA experience to create a design which was modelled and tested in numerous environmental conditions. The Accession modular design starts at 3.50m and offers 12 hours endurance for hydrographic surveying at typical survey speeds. Then, with either the addition of a 0.75m or 1.50m section of hull and various payload and/or fuel combinations, the vessel can operate in excess of 8 days at sea.
Built by surveyors for surveyors, this adaptable USV is simple to operate, reliable and robust enough to withstand operating in offshore conditions. The Accession Class USV can operate as a lone survey vessel or as a force multiplier from a mother ship increasing productivity and lowering costs.
Additional capabilities include the integration of Unmanned Airborne Vehicles (UAV’s) for combined autonomous operations on the sea and in the air offering inspection and security capabilities. Other optional payload integrations include mobile laser scanning, Sound Velocity Profiling (SVP), Geophysical senor towing and Remotely Operated Vehicle deployment (ROV).
The Accession USV is the first truly modular USV adaptable for nearshore operations by Port Authorities to offshore applications by survey companies.
The definition of Accession is the 'attainment of power', and she is available to rent or buy.
