4DOcean, XOCEAN Deliver 2,000 Hours Bathymetric Survey

4DOcean and XOCEAN have recently completed over 2,000 hours of unmanned bathymetric survey off the coasts of Scotland and England.

The survey is part of the UK’s Lot 2 Civil Hydrography Programme (CHP), administered by the Maritime & Coastguard Agency (MCA) subcontracted by Meritaito.

Operating two different unmanned vessels, 4DOcean and XOCEAN completed surveys of multiple nearshore locations between December 2018 and March 2019.

Duncan Mallace, managing director of 4DOcean, said: “These were ground-breaking surveys as both ASVs were operated independently, without mothership but monitoring and watch-keeping from shore 24/7. The unmanned vessels were used to map the shallow uncharted waters, while the manned vessel completed the deeper areas. A normal single survey team was used to collect and process data from both unmanned vessels.”
