5000+ Boulder Clearance success in winter

Home | News | Projects | 5000+ Boulder Clearance success in winter

Offshore Marine Management (OMM) has successfully cleared 5,000+ boulders from 30km of the Baltic seabed ahead of schedule during the winter months in the German Baltic Sea.

Utilising three specialist vessels to clear the pathway of boulders ranging in sizes up to 2M, the offshore marine project team successfully created a suitable pathway for an export cable for the on an Offshore Wind Farm connection to the shore landing site.  This was going from deep water to working within 5metres of water and less.

Completing the boulder removal across a range of depths, including exceptionally shallow watersOMM showcased their expertise and understanding of the marine environment by adapting their techniques, which required a high level of control when mitigating the risk of weather and collision with boulders on the seabed, and continuing to deliver the highest level of safety.

Though a combination of project planning and execution skills, seamless team work and the application of the latest technology, a clearance rate in excess of 100 boulders per day was achieved. The opportunity to utilise their approved supply chain to pull together the offshore management and team, specialised tools for water depths and the importance of the selection of the right vessel partner saw the project complete a month earlier than expected, exceeding expectations of our client.


Perry Symons, Chief Operating Officer for OMM commented:

“The success of this job is testament to the high calibre of people at OMM and their offshore partners.

We were able to effectively and efficiently coordinate and manage the vessels, team and boulder extraction. We are thrilled at the outcome and to have achieved a fantastic result.

OMM coordinate and manage a range of offshore requirements and have a strong track record in supporting clients through their flexible and adaptive approach.
