MacArtney has provided offshore cable handling equipment for Hornsea Project One offshore wind farm.
The scope of supply of this DONG Energy order for the Hornsea Project One offshore wind farm covers three MacArtney 160 kN electrical cable pulling winches including three comprehensive spare parts packages for each of the three winches.
The purpose of the winches is to bring array cables and export cables from the sea-bed onto the substation decks. The power cables are to be pulled through a total of 15 J-tubes onto each sub-station for connection. The actual winch is rotatable for direct 360 degrees operation and the pull is generated through 250 m Ø32 Dyneema rope.
MacArtney supplies 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.
