The SEA-KIT H-Class USV’s highly configurable design, with a retractable gondola and dual sensor deployment options, is based on a operational data and feedback collected from the proven and established X-Class USVs. This USV is available in both 12m and 15m variants. Both 12m and 15m variants can be davit launched, with the 12m transportable in a standard shipping container.
As well as increased power, seakeeping and fuel capacity, the vessel has a composite hull, reducing the ship’s weight with the resulting fuel saving and endurance benefits. Active stabilisers minimise roll and improve data collection quality.
The H-Class design also further reduces surface and subsurface noise and vibration. Reduced risk to personnel as well as significantly decreased costs and environmental impact remain an integral aspect of the H-Class – SEA-KIT’s latest step towards the company’s ultimate zero emissions goal.
Enhanced design development means that this vessel offers flexible operational parameters. It can accommodate a variety of sensors in its retractable gondola, such as a Single or Multi Beam Echo Sounder or a Sub Bottom Profiler. In addition, the USV can deploy a tow cage, SVP, MAPR, CTD and towfish/side scan sonar for successful deepwater and nearshore bathymetric and hydrographic survey missions.
The SEA-KIT H-Class is designed to MCA Category 0, ensuring over-the-horizon endurance capability. Its increased endurance means that multiple missions can be undertaken without the need for frequent returns to shore for refuelling.
SEA-KIT USVs are controlled using SEA-KIT’s proprietary G-SAVI control and surveillance platform, which provides safe and secure operation from remote control centres. Data can be transmitted via broadband link or satellite following on-board processing and compression or stored on-board for future retrieval.
The SEA-KIT H-Class design will hold Unmanned Marine Systems certification from Lloyd’s Register as well as Lloyd’s Register approval for design and hull construction.
