Safeway reaches record transfer speeds at latest offshore wind charter

Monday, 16 April, 2018 - 14:30

As from early October last year the Safeway motion compensated offshore access system of the Dutch Van Aalst Group is installed on the 95-metre long OCV ‘Olympic Intervention IV’, owned by Olympic Subsea ASA, Norway. Without any significant downtime, the 28 m long walk-to-work Seagull-type has safely transferred workers and their tools at a high pace from the ‘Olympic Intervention IV’ to offshore wind turbines of Adwen, part of Siemens.

“Our gangway in combination with the ‘Olympic Intervention IV’ proved to reach new record speeds in transferring people and cargo. Last year Siemens gave us a challenging benchmark for this vessel/gangway combination; from sail away to turbine, DP positioning, deploy and transfer 6 people and 3 cargo loads, return in sailing position within 30 minutes. We, together with Olympic are very proud of this achievement, proving a realistic base for preparing offshore operations. This will contribute to the overall industry costs savings, lowering installation and maintenance costs of offshore windfarms”, said Remko de Boer, General Manager at Safeway.

The transfer operations proved an remarkable score in reducing costs where Safeway could reach positions on Borkum-West and Wikinger windfarm without any modifications to the gangway or pedestal. This is due to the standard 10 m vertical height adjustment of the gangway.

During the previous charter at Borkum West, Safeway performed over 10 average daily cargo transfers and topped at 13 transfers in 12 hours. These transfers were performed using the tip hoist of the gangway, acting as a 3D lift. The shift from personnel to cargo transfer mode does not take up any time thanks to the new designed load handling A-frame arrangement.

Frank de Vries, Project Manager at Safeway indicates: “Safeway unique hover mode allowed the client to land on all sides of the turbine. This allowed maximum flexibility in vessel positioning in given weather conditions. Being  the only class approved hover system in the market, its safe and successful deployment contributed to the efficiency of the vessel - gangway combination to great satisfaction of the client.”

Wijnand van Aalst, Managing Director at Safeway, says: “In recent months this combination of vessel and gangway has undeniably demonstrated to be able to outperform others in offshore wind farm projects during commissioning as well as maintenance campaigns. With our aggressive fleet building plan well underway at this very moment, we continue to expand our presence in more challenging areas and soon more customers will be able to benefit from Safeway’s unique features such as roll compensation, height adjustment, zero impact bumpering/hover and counterweight. It is an absolute ‘game changer’ as promised one year ago during the introduction. We are always focused on making life safer and easier for our customers by providing them with a safe, reliable, cost-efficient and more effective method of transferring offshore personnel and cargo.”
