Ecosse Subsea Systems (ESS) has secured a boulder clearing and multi-pass trenching contract for EnBW's Baltic 2 offshore wind farm project in Germany.

As part of the deal, ESS will deploy its SCAR plough system for clearing and pre-lay trenching operations over a 90km route.

Baltic 2 is an 80 turbine development located 32km north of Rügen island in the Baltic Sea.

ESS will provide a trench design for each array cluster and all pre-engineering services, including the provision of plough tips for variant soil conditions and plough cut depth configuration.

Under the project, boulder clearance and multi-pass trenching to 1.5m depth is also due to take place.

ESS said it will use its own ROV system to monitor, survey and record operations, while a vessel-mounted multi-beam will be used to determine the trenching's quality.

ESS managing director Mike Wilson said that the SCAR ploughing system can work in shallow and very deep waters, and handle diverse soil types.

"Its multi-functional capacity allied to being able to work from almost any type of vessel with smaller crews is a real game changer for contractors and operators who want to control costs while obtaining consistent results which offer optimum subsea cable protection," Wilson said.

Baltic 2 follows on from Germany's first commercial offshore project, Baltic 1, which was commissioned in May 2011.
