Work on the project began in May of 2006 and by July the piles which form the foundation for the turbines had all been installed by the specialist jack-up vessel ‘Jumping Jack’, from which the piles were driven into the seabed using a powerful Menck hammer.

At this point in time, a diving team from first time Seawork exhibitor Osiris Underwater Engineering Services was deployed to lay pipes and cables between monopiles before the turbines were installed atop them. Working at water depths to 18m, the five man Osiris team spent six months using jetting and airlift systems to liquefy sand on the Liverpool Bay seabed into the pipes and cables could sink. Osiris also provided some ten tons of equipment to main contractor SeaScape, much of which is still in service.

Also operating as specialist consultant regarding safety procedures, Osiris provided its own decompression chamber and demonstrated solid professionalism in meeting all client requirements.

West Yorkshire based Osiris Underwater Engineering Services travels this summer to Seawork 2007, where it will occupy a stand in the DiveWork component of the show. Aiden West and colleagues will welcome visitors to discuss how the Osiris range of services, broadly split into General Construction, Inspection, and Specialist areas, can be delivered in support of wide ranging marine activities.
