FoundOcean has been awarded the offshore grouting contract for Walney Offshore Wind Farm (OWF) Phase 2 substation installation by Volker Staal en Funderingen BV.

The substation jacket is a four-legged steel structure with one pile sleeve per leg. The jacket will be secured to the seabed by injecting grout into the annuli between the pile and the sleeve. The type of cement used will be Portland Cement CEM I Type 52.5N.

The jacket has been designed with a conventional grouting system with primary and secondary grout lines. The grout line connections are located on the work platform.

Jim Bell, Managing Director for FoundOcean commented, “We are delighted to be working with VSF once more on the Walney OWF project following our successful completion of the Phase 1 substation in 2010.”

“The two companies have worked together several times already, and FoundOcean complements our professional approach to ensure a fast and perfect execution of the project,” acknowledged Laurent van Mansfeld, Manager International Operations for VSF.

VSF is performing the piling works for Scaldis Marine Contractors.

The grouting operation is due to mobilise in April 2011, weather permitting.
