Location: Irish Sea, United Kingdom
Client: Ormonde Energy Ltd
Period: July - September 2010
Scaldis was awarded the contract, along with GeoSea, its sister company, to transport and install substructures for 5MW wind turbines in the Ormonde field. Additionally,HLV Rambiz and Swiber Else Marie installed 31 jackets in pre-installed piles in the Irish Sea, offshore Barrow in Furness, UK.
The Ormonde wind farm construction started in the spring of 2010. The scope of work included :
- transportation, installation and measuring of pin piles (GeoSea)
- transportation and installation of jackets including grouting (Scaldis)
- lifting and placing of the substation deck (Scaldis)
Scaldis transported the 31 WTG foundation jackets and substation jacket on extended North Sea barges from the fabrication yard on the northeast coast of the UK to the mid-west coast. Each barge contained four jackets, positioned vertically. Once on site the HLV Rambiz lifted the jackets from the barge and inserted them in the pre-installed piles. Once a jacket was placed, a separate DP II grout vessel inserted grout into the annulus between jacket and piles. Finally the 1000 ton substation deck was lifted by HLV Rambiz onto the substation jacket foundation.
