Videos Show Wind Farms Need Logistics Too - Cooperation with Project Freight Forwarding Outfit

Fascinating Animation Demonstrates How Technology Enables Fitting of Giant Pieces
Shipping News Feature

NETHERLANDS – WORLDWIDE – The Dutch firm of Conquest Offshore which has assisted recently in such projects as the salvage of the Costa Concordia and the construction of London’s new super port at London Gateway, also specialises in assisting in constructions for the burgeoning wind turbine industry, working alongside project freight forwarding outfit Deugro to help with the logistics required to locate the giant pieces accurately on the seabed. Conquest has now released a set of animated videos to demonstrate just what is involved, something which turns out to be a lot more interesting to view than might be expected.

In the two films just released, an animated version of the company’s Conquest MB1 barge can be seen demonstrating the efficient system it has worked out, in collaboration with Deugro, for installing Monopiles (MP’s), Transition Pieces (TP’s) and the Pre-piling of sub surface Jackets. The Animation for Floating Installation of Monopile and Transition Pieces can be seen HERE whilst the Pre-piling of Jackets is viewable HERE.

The 136 metre long Conquest MB1 barge is the perfect tool to execute this kind of work. Three monopiles, or up to 16 Transition Pieces, can be stored on deck via the effective skidding system. Upending of the giant, cumbersome pieces can be done on deck or floating but the real challenge is the floating installation of the MP’s. As the video shows, the specially designed motion compensated pile gripper (MCPG) is the key to success.

Conditions at sea are of course particularly challenging so, while hammering the pile, hydraulic cylinders actively compensate the surge, sway and heave motions of the barge to ensure the verticality within limits. Conquest says the gripper and the relative good workability of the Conquest MB1 barge with its anti-heeling system (8000 m3 per hour), creates a game changer in offshore wind industry.
