Swedish Power Company, Vattenfall, commissioned a bespoke heavy-duty pontoon for Aberdeen Harbour to provide a robust berthing facility for crew transfer vessels (CTVs) and working vessels during the commissioning and ongoing maintenance of the Aberdeen Offshore Windfarm.
|Where||Aberdeen Harbour, East Coast of Scotland|
Space in the busy commercial port is at a premium so we limited the pontoon’s footprint on the quay wall by mooring it off the wall on three driven tubular piles. The size of the piles (0.9m diameter x 24m long) meant using a jack up barge for this marine installation, which we completed with subcontractor ABCO Marine.
We worked closely with Vattenfall and the Aberdeen Harbour Board during the design phase to ensure we maximised use of space, while not compromising on the functionality and durability of the pontoons.
The pontoons are equipped with electrical points to offer power to the vessels as well as high level mast lighting and an anti-slip Glass Reinforced Concrete (GRC) pontoon decking, allowing for year-round safe working conditions on the pontoon, day or night.
Finished in 2018, the 30m x 6m floating pontoon system with a 1m freeboard, matching the that of the vessels’, is now essential for operatives working on the offshore windfarms to safely gain access to their transport.
