Challenge

EnBW contracted MRE to assist with the provision of temporary power during the construction and commissioning phase of the 71 Siemens SWT-7.0-154 type turbine installation at the Hohe See offshore wind farm.

Solution

MRE supplied modular temporary power packages, consisting of a 116 kVA generator, custom-built fuel tank and bespoke lifting frames.

The MRE owned Manor Venture and associated offshore personnel were also contracted by EnBW to maintain and refuel the offshore generators.

Based out of the port of Esbjerg in Denmark, the Manor Venture delivered over 450,000 litres of fuel to the 65 generators required during the construction phase of the windfarm.

Over the 170 days worked on the project and often remaining in the field for up to 5 days at a time, the vessel completed over 3,300 safe transfers of personnel, to maintain a 99% serviceability record of our generators.

On completion of the temporary power requirement, MRE chartered the DP2 offshore crane vessel, Olympic Ares, to demobilise all sets from their respective transition pieces; all 65 units were then delivered by the vessel to MRE’s home port of Portland, Dorset.

Conclusion

MRE successfully assisted EnBW during the construction phase, supplying the temporary power that resulted in the completion of the turbine build and generation of power from the Hohe See OWF.
