Ecosse Subsea Systems (ESS) has successfully
completely a major boulder clearance and seabed preparation campaign on
behalf of one of the leading energy groups in northern Europe, DONG Energy.
The subsea engineering specialist cleared
almost 50,000 boulders and other obstructions from 33 routes spread over
a distance of 40km at the Westermost
Rough wind farm, located eight
kilometres off the Yorkshire coast.
ESS deployed its multi-functional SCAR
seabed plough and, working from the Havila Jupiter vessel, completed ploughing
and surveying operations within 20 meter corridors located between 33 turbines
and the offshore sub-station.
The 72 day campaign, which had been mobilised
in a 47-hour time-frame from Aberdeen, was delivered on time and within
budget, and demobilisation took less than 24 hours. ESS’s highly experienced
offshore management and operations team included survey and ROV specialists.

Mike Wilson, managing director of Aberdeenshire
based ESS, said: “Another successful seabed clearance project has been
completed safely and ahead of schedule on behalf of a leading European
energy group.
“The workscope covered multi-pass
boulder clearing on up to 33 routes, covering an area of 720,000 sq meter
and involved complex seabed navigation with ROV back-up to ensure pinpoint
accuracy between passes.
“Our SCAR plough is now well-established
as preferred tool by leading oil, gas and Renewables companies and its
credentials as a safe, economic and reliable seabed clearance solution
has caught the attention of many of the major operators.”
The Westermost campaign was ESS’s third
seabed clearance contract in the renewable sector – following on from
Baltic 2 and Humber
Gateway projects - and the
subsea specialist has carved out a reputation for speedy, accurate and
cost-efficient seabed clearance expertise.
