Unexploded mine and bomb specialist Ordtek has secured its first offshore windfarm contracts in the US and Taiwan with energy giant Ørsted.
The Norfolk, UK-based unexploded ordnance (UXO) risk management experts will support Ørsted on two offshore windfarms to be developed off the US east coast, Bay State Wind and Ocean Wind. It will work with Ørsted in Taiwan.
The contracts were secured after Ordtek’s UXO risk management work with Ørsted on the Walney Extension and Hornsea Project One windfarms in the UK.
Hornsea Project One rewrote the records for UXO finds on an offshore windfarm, exceeding the 40 items identified by Ordtek on Race Bank in 2015.
In Taiwan, Ordtek will research and risk assess for contamination ahead of construction of Ørsted’s Formosa 1 and Greater Changhua offshore windfarms.
Ordtek launched its interactive online ‘MineMap’ for UK waters in 2016.
The risk map shares data the company has collected about areas mined by the British and Germans during the wars, and UXO from military armament training and munitions dumping. MineMap, which reveals previous UXO finds, has helped to find and remove scores of UXO munitions for offshore wind developers. The mobile-friendly mapping service was extended to Danish waters and, more recently, to Belgium and the Netherlands.
Ordtek has also entered a partnership to produce UXO and boulder detection best practice guidelines for the offshore environment with offshore geoscience and geotechnical engineering consultancy Cathie Associates.
The work will examine new and existing survey technologies as well as acquisition and interpretation methods to enable developers to identify the best methods to address the UXO and boulder risks to their projects, and ensure they are undertaken at best practice standards.
