With bases in the Netherlands, U.K., India, Africa and the Middle East, integrated subsea infrastructure services provider N-Sea serves all major North Sea operators and service companies, supporting customers through survey, inspection and assessment of their assets. N-Sea also installs, inspects, repairs and maintains infrastructures throughout the entire lifecycle, in addition to near shore, offshore and survey services.

The company’s personnel and fleet deliver a range of subsea activities and subsea interventions including: air diving services and the innovative TUP Diving System (Transfer Under Pressure); construction and positioning support; excavation services; inspections by diver/ ROV; pipeline and cable inspections using WROV; geophysical survey and geotechnical investigations; UXO management. N-Sea is particularly known for its safety innovations within the diving sector. The TUP Diving System (Transfer Under Pressure) is a modular system consisting of a three-man closed diving bell, launch and recovery system, triple-lock decompression chamber, gas diver control (air/mixed) and hyperbaric rescue craft. N-Sea also deploys a modern fleet of ROVs/ROTVs and vessels for survey, diving and construction purposes. The DPII DSV and Survey/ROV support vessel the Noordhoek Pathfinder accommodates 40 people and is equipped with a 25 metric ton offshore crane, single and multibeam echosounder. This survey spread can be supplemented by ROTV mounted sidescan sonar and/or multibeam echosounder, geotechnical equipment and\or ROVs as required. The DPII DSV Siem Stork is a dive, multi-support and construction vessel equipped with azimuth thrusters for economic operations. The vessel is fitted with complete air and nitrox diving spread and diving daughter craft. 
The ship, with its diesel electric propulsion system and optimized hull lines, is designed for low fuel consumption and excellent seakeeping.
