launch and recover remote vehicles such as large AUV/UUVs or ROVs for missions including deep-water bathymetry, offshore and subsea asset inspection and hydrographic survey with reduced risk to personnel, decreased costs and lower environmental impact. A large payload capacity, long range and over-the-horizon endurance means that multiple missions can be undertaken in a solo capacity or as part of a larger fleet of crewed or uncrewed vessels. Data can be transmitted via broadband link or satellite following on-board processing and compression, or stored on board for future retrieval. 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. The SEA-KIT X class design holds Unmanned Marine Systems certification from Lloyd's Register. Maxlimer is long and wide. She has a diesel-electric propulsion system, which gives her a top speed of around and extended endurance capability up to 14 days. Although her speed is low, SEA-KIT claims that Maxlimer uses only 5% as much fuel as a comparable crewed vessel as a result of weight savings and efficiencies in the propulsion system. Maxlimer can operate autonomously, depending on conditions, or under remote control from a shore-based command facility. References Unmanned surface vehicles Research vessels of the United Kingdom
