Angular boom tip by Ampelmann lets workers safely install new north sea offshore wind farm

Thursday, 14 December, 2017 - 12:15

Ampelmann, the global leader in offshore access solutions, has created, in cooperation with Seaway Heavy Lifting, an industry first innovation allowing workers safe and efficient access to install the jackets for 84 wind turbines on the Beatrice Offshore Windfarm Limited project in the Outer Moray Firth.

Global offshore contractor Seaway Heavy Lifting awarded the EPCI contract to Ampelmann to design and create an Angular Boom Tip. This will allow secure connection at difficult angles for safe gangway transfer between the 5,000 tonne heavy lift vessel (HLV) Oleg Strashnov and the 2,500 tonne HLV Stanislav Yudin to install 84 individual wind turbines.

Conventional gangway tips are rounded which can fit on the majority of offshore wind turbines or offshore assets. However, due to the size of the HLV, its close proximity to the jackets and the location of its access gates, Ampelmann custom-made the V-shaped tip at the end of the 25-metre gangway to give workers easy access to build and manage each new wind structure.

Friso Talsma, Ampelmann’s Manager Sales and Business Development for Offshore Wind said: “Though the tip is a quite a straightforward piece of steel, the rubber covered angular shape now allows us to land at difficult angles as small as 45 degrees, while eliminating the risk of gaps between gangway and structure. It’s a new innovation, tailor-made for this particular project and overcomes a significant safety and potentially costly challenge faced by the operators to ensure safe access to the structures. It’s an industry first and no other competitor has such a solution.”

The design, development and installation of the detachable tip took around two months and is deployed on the Beatrice project using the company’s A-type motion compensated gangway system which is able to transfer people with zero movement in significant wave heights of up to three metres.

Talsma continued: “This type of solution can also be adopted by the oil and gas industry in certain situations. For example, if the type of angles change, the tip can be adapted to suit
and solve that problem or a new bespoke version created. Ampelmann is always open and flexible to find solutions for our customers. No is never the answer. We have so much experience of Walk to Work in the offshore industry that we are fully aware of the challenges and the potential solutions.”

The Beatrice Offshore Windfarm Limited Project is expected to power approximately 450,000 homes - around three times the number of homes in the Moray and Highland regions of Scotland. Offshore construction began in 2017 and is expected to become fully operational in 2019.
