TWO NEW WORKBOAT BERTHING FACILITIES FROM WALCON MARINE GREAT YARMOUTH (DUDGEON WIND FARM) AND SEAWORK INTERNATIONAL 2016
Walcon Marine has recently completed work on two berthing facilities, designed and built specifically to take the rough and tumble of workboat operations. One of these is an installation (pictured) at Great Yarmouth for vessels supporting the build and future maintenance of the 402 MW Dudgeon Wind Farm. This forms part of the infrastructure of the purpose- built Operations & Maintenance base for the windfarm, which will provide 24/7 access to the project throughout its lifetime.
Walcon was contracted by Offshore Design Engineering to design and install the 52-metre jetty on one section of the waterfront. A series of heavy duty System 21 pontoons three metres across and 11.5 metres in length form the basis of the structure, with 600 mm of freeboard. Handrails have been fitted at each end and along the back edge, and the decking is tough GRP mesh. Additional features include fresh water, safety pedestals, lighting, navigation lights and CCTV.
The foundations for the 67 turbines for the windfarm and the offshore cabling are currently being installed, and it is expected to be fully commissioned by the end of 2017.
This year Seawork International, Europe’s largest commercial marine and workboat exhibition, has a new location within the port of Southampton and a new marina to go with it. Built as in previous years by Walcon Marine, it will accommodate over 60 boats for the duration of the show, ranging from RIBs and small pilot boats right up to a 300 GT, 27m x 12.5m Multi Cat workboat by Damen Shipyards.
Over 7,500 visitors are expected to attend the three-day show and walk the heavy duty, System 21 pontoons. The outer units are Waliflote wave attenuating pontoons. Facing south west, their near continuous concrete wall will protect the vessels inside from any wave action coming across Southampton Water. To allow safe access for the exhibitors and guests, Walcon has also built and installed the 30 metre Warren Truss access bridge.
All three of Walcon’s barges have been involved in the build; undertaking activities including driving in the piles and bringing in materials by sea.
