In the English Channel, located approximately 13 km South of Brighton, Volker Staal en Funderingen finished the installation of an offshore substation platform comprising a piled jacket and topside construction for the Rampion Offshore Windfarm.
Scaldis SMC was awarded the Transport & Installation contract by E.ON Climate & Renewables UK Rampion Offshore Wind Ltd. Subsequently VSF was awarded the subcontract for pile installation and grouting operations of the jacket.
Mid-September the heavy lift vessel Rambiz was mobilized in Flushing and hereafter sailed directly to the South coast of England. After a successful jacket touchdown, VSF performed the piling operations of all jacket piles. An IHC S-1400 Hydrohammer, fitted with an 2500mm sleeve and powered by one P-300W power pack, has been used. The provision and operation of an Internal Lifting Tool also formed part of the VSF scope, required for upending/stabbing of the jacket piles.
The grouting scope also formed part of the VSF subcontract. In total 77 tonnes of OPC CEM I 52.5N was supplied, mixed and pumped into the jacket sleeves.
Pile dimensions:
- 4 piles Ø2200 x 50 mm with a total length of 38,3 metres
Depth:
- Penetration into seabed 24,0 metres.
Weight:
- Net pile weight approx. 101,4 tonnes
