XOCEAN completes Hornsea One survey using Uncrewed Surface Vessel

XOCEAN recently delivered a site investigation survey on the Hornsea Project One wind farm using an Uncrewed Surface Vessel (USV).

The purpose of the survey was to demonstrate the ability of XOCEAN’s XO-450 USV platform to monitor scour around wind turbine generator (WTG) foundations and the cable depth of burial of inter-array cables. The USV conducted the offshore operation in three-and-a-half-days, mobilising from Bridlington Harbour in Yorkshire. The vessel was launched and recovered from shore, approximately 120 kilometres from the offshore surveying location.

The USV was launched and recovered from shore and transited 120km to the survey location in the southern North Sea during the three-day mission.

The USV completed the survey in site conditions of up to 1.9m maximum wave height, providing accurate and high-resolution seabed data in 30m water depths. XOCEAN’s uncrewed vessel was remotely monitored and controlled 24/7 via a satellite connection by a team of USV Pilots and Online Surveyors who remained onshore, working from their home offices, monitoring the vessel and data quality throughout the mission.

The USV incorporates a hybrid power system with approximately one-thousandth of the emissions of a conventional crewed survey ship. XOCEAN stated that all carbon produced during the project was offset, resulting in fully carbon neutral data.

Developed by Danish energy giant Ørsted, Hornsea Project One is the world’s largest offshore wind farm to date. It is located in the North Sea off the east coast of England. The site consists of 174 Siemens Gamesa Renewable Energy. SWT-7.0-154 turbines, spanning across an area of 407km², all of which have been installed. The site was fully commissioned at the end of 2019 and is anticipated to power over one million homes in the UK.

Commenting on the project, James Ives, CEO of XOCEAN, said: “We are delighted to be working with Ørsted on this ground-breaking project. This mission demonstrates how our uncrewed systems deliver a safe, reliable and carbon neutral solution to ocean data collection for the Offshore Renewables sector.”

In a separate announcement, XOCEAN revealed that it has entered into a framework agreement with SSE Renewables to support survey operations across their project portfolio. Under the agreement, its USV completed further survey operations at the Greater Gabbard offshore wind farm in late December 2020.
