Greek Assodivers Underwater Contractors have taken delivery of two MERMAC winches from MacArtney to be used on the Kriegers Flak offshore wind project in the Danish Baltic Sea.
The delivery consists of one 19.5 ton AHC (active heave compensation) winch and one 6 ton umbilical winch. In addition, the scope of supply includes electrical slip rings, junction boxes, MRUs, extra level wind guide roller kits and wireless remote controls.
The AHC winch is intended to relocate huge stones from the seafloor, and the umbilical winch is to be used for pulling a cable plough.
Electric AHC winch solutions are often preferred for ROV systems and for handling equipment that is to operate near or on the seabed, MacArtney said. AHC immediately compensates for vessel movement caused by waves, even in heavy seas. This feature reduces weather-related downtime and considerably facilitates launch and recovery of tethered equipment, the company said.
”This is not the first time we’ve placed an order with MacArtney. Our business relations go further back and emphasize the fact that we always rest assured to be granted superior customer service and product quality on the part of MacArtney,” said Sarantos Konstantatos, Procurement Officer, Assodivers Underwater Contractors.
The Kriegers Flak offshore wind farm is owned by Vattenfall and will comprise 72 Siemens Gamesa 8MW turbines, expected to be fully operational by 2021.
Assodivers is responsible for cable burial works at the Kriegers Flak Combined Grid Solution (CGS), a project that will interconnect Danish and German grids via Kriegers Flak and Baltic 2 offshore wind farms.
