Turbine Installation Start

Turbine (tower + WTG) installation at Offshore Windpark Egmond aan Zee (OWEZ) commenced on 30 May 2006 per the agreed project schedule between NoordzeeWind and the Bouwcombinatie Egmond (BCE) EPC consortium, as recorded in the Section 5 "Planning Versus Execution" Gantt chart of the OWEZ-R-141 General Report (Task 34 "Installation towers and WTGs", Start Tue 30/05/06, Finish Sat 19/08/06). Installation ran in parallel with monopile + transition piece installation (Wed 29/03/06 → Tue 25/07/06), with the offshore works themselves opening on 21 March 2006 with the first scour-protection filter layers. The turbine installation campaign deployed A2Sea's specialist installation vessel The Sea Energy, working out of the IJmondhaven (IJmuiden) pre-assembly quayside. Nacelles, hubs and two-blade pre-assemblies were prepared on-quay; The Sea Energy carried two complete WTG sets (two nacelles + two blades each + two towers) per round trip, lifting them onto monopile transition pieces using its onboard crane. The schedule planned completion by 19 August 2006, with first power following by 1 November 2006 (MEP subsidy commencement) and substantial completion of Sections A and B on 31 October 2006 plus Section C on 31 December 2006. Pre-assembly site readiness, harbour logistics, and parallel foundation + WTG vessel utilisation made OWEZ an important workflow precedent for subsequent European offshore wind installations.
