MacArtney has won a contract to deliver electrical cable winches which will pull array cables and export cables from the seabed onto the substation decks of DONG Energy’s 1.2GW Hornsea Project One wind farm off the Yorkshire coast.
Hornsea Project One is equipped with three offshore substations. The scope of supply covers three MacArtney 160 kN electrical cable pulling winches including three comprehensive spare parts packages for each of the three winches.
The power cables are to be pulled through a total of 15 J-tubes onto each substation for connection. The actual winch is rotatable for direct 360 degrees operation and the pull is generated through 250 m Ø32 Dyneema rope.
MacArtney will also provide additional equipment consisting of a DNV approved password-secured ‘capacity reduction mode’ which enables cable installers to use smaller sheave blocks to install the inter array cables. In addition, the supply includes an integrated data logger with an extra large 15.4 inch HMI, and 360 degrees rotation for optimised operation, which reduces the costs of reversible units and sheave blocks. Additionally, Dyneema ropes have been chosen for reasons of simplified operation, the company said.
The scope is designed and manufactured according to DNV/GL 2.22 certification, to CE marking, and to LOLER.
”We are happy to be part of this project. We believe in setting the bar high and the project reflects both good team work and long-standing competences when it comes to project management, designing, engineering, and constructing appliances required by the offshore wind sector,” said Søren Hartvigsen, Technical Director of MacArtney Manufacturing.
