Submarine Technology Limited

STL Research is a consultancy, design, development and ‘one-off’ project implementation group, specialising in the offshore and sub-sea industies. Initially operating from Aberdeen and now based in Cowes, STL Research has been involved in many leading edge projects within the offshore and subsea markets. Two key focus areas are safe and efficient personnel access (Neptune), and the safe launch and recovery of autonomous marine equipment under local or remote control (Proteus). The Neptune 20M Personnel Access System enables transfer of personnel with equipment, or cargo, from a vessel via a gondola, to a fixed or floating, offshore structure with full (6DoF) motion-compensation to remove wave-induced motion. Proteus is an innovative, stand-alone, deck mounted launch and recovery system, which uses computer vision to automatically synchronise movement of the interchangeable coupling tool with the target, to eliminate wave-induced motions, which eases attachment and safe retrieval of ROV, AUV, ASV. Legacy projects include diving systems, hyperbaric lifeboats, HP/HT valves, well head control & monitoring systems and automatic ultrasonic NDT.
