Peterhead Port to support EOWDC construction

Peterhead Port Authority is set to support offshore construction work for the European Offshore Wind Deployment Centre (EOWDC) after signing an agreement to harbour the suction bucket jacket foundations for the project.

The contract for Peterhead Port Authority was awarded by Boskalis which is Vattenfall’s key supplier for the offshore construction and installation including the foundations and cabling.

Ian Laidlaw, chief executive at Peterhead Port Authority, said: “The Port Authority is very pleased to be able to play a key role in the EOWDC project as it emphasises Peterhead’s experience and the range of services that the Port can offer. It also provides important opportunities for our established supply chain partners.

“Peterhead has been an integral part of the UK’s energy industry for the past 50 years and the EOWDC represents a new chapter in the vital role that the energy sector plays in support the national economy.”

Further to foundations, the agreement will also see the Port play host to one of the world’s largest floating cranes, with a maximum lifting capacity of 5,000 tonnes, and up to six barges that will transport the 11 foundations. Five of  the barges will carry two foundations each while the sixth will transport the final one- the heaviest which weighs around 1,800 tonnes and is about 77m high.

Peterhead Port Authority will also accommodate two supporting offshore construction vessels while a project site office will be established at the harbour for the installation operations which are due to start later this year.

The foundations will be transported to Peterhead for mooring via the six barge vessels, . The installation vessel will be moored alongside the barges for heavy-lift operations. When offshore work starts, more than half the foundations will be installed under the water within the seabed.

Adam Ezzamel, Vattenfall’s project director for the EOWDC, said: “We welcome the selection of the experienced Peterhead Port Authority to marshal the massive steel structures needed for the cutting-edge EOWDC, and which builds on our investment with the project in the north east.

“We are sure the sheer scale and prominence of the pioneering technology and work involved with the EOWDC will create a positive renewables momentum for the region putting the north east at the centre of international offshore wind innovation.”

Peterhead Port is to support the installation operations for at least four months with the offshore work expected to take around four to six weeks.

Andre Andringa, project director at Boskalis, said: “Peterhead Port Authority’s facilities provide a natural fit to support the foundation installation work for a number of reasons. With more than 3km of deep-water berthing, it can comfortably accommodate a large heavy lift vessel while the harbour is also sheltered which helps minimise the impact of weather conditions for loading.”

The EOWDC is believed to be the first UK offshore wind project to deploy suction bucket jackets of this kind on a large scale. The buckets have been designed to enable faster offshore installation, while keeping noise to a minimum, and allow easier decommissioning as the installation process is reversed. Vattenfall stated that the technology will contribute to driving down the cost of clean power as offshore wind moves into deeper waters and more complex seabed conditions.

The project is valued in excess of £300m (€332m) and will feature 11 MHI Vestas V164-8.0MW turbines. With an installed capacity of 92.4MW the project is expected to produce enough electricity every year to meet the equivalent annual demand of 78,000 homes.

The project has been awarded up to €40m (£36m) of funding from the European Union and is supported by Aberdeen Renewable Energy Group (AREG). It is anticipated to generate first power in 2018 and be operational for 20 years. MHI Vestas will carry out a maintenance agreement during the projects operation.

Vattenfall stated that the project will enable it to help the industry reach its goal of continuously reducing the Levelised Cost of Energy (LCOE) by allowing the testing of evolving technology. Furthermore, it will be only the second wind farm in the industry to use 66kV.

At the end of November 2016, Vattenfall signed a lease totalling 24 years with Aberdeen Harbour Board. The company plans to establish its construction team’s base within the Regent Centre and also move into a warehouse unit at Commercial Quay.
