ALE’s marine investment, the SARAH S barge, has been deployed on its inaugural project to transport transition pieces (TPs) for the world's biggest offshore wind farm.

ALE was contracted to provide specialist offshore engineering services as well as the marine transportation, sea-fastening, load-out and ballasting of over 100 TPs for Ørsted’s Hornsea Project One. For the engineering, the Conbit team performed the structural integrity and sea fastening calculations of the grillages on the barge deck.

ALE began the project in March, preforming the load-out the TPs from the fabrication yard onto the barge. Each TP weighs 337t and measures 25m high.

Once on the barge, the TPs are transported along the River Tees to the discharge berth. The SARAH S is 3m narrower than most North Sea barges, making it ideal for this project, as it can fit between the quayside and the offshore installation vessel and falls in line with the vessels crane radius limits, for transferring the TPs.

“This project demonstrates our ability to offer the full, specialist marine scope of work. From utilising our internal expertise and engineering unique solutions, to offering an extensive fleet and operative skills, we can manage the complete project,” explains Steve Small, Commercial Manager – Marine.

Furthermore he added, “we have the variety to select the most suitable vessel for the project location and scope, ensuring the client saves time and costs on the project”.

So far, ALE has loaded-out the first five TPs and completed the first discharge onto the installation vessel. ALE expects the project to last until the end of 2018.

Poised to become the world’s biggest wind farm, Hornsea Project One is anticipated to produce enough clean energy for over one million UK homes. It is located 120km off the Yorkshire coast and will consist of 174 turbines due to be commissioned in 2020.

Offshore construction recently kicked off with installation of the first foundations by GeoSea’s jack-up vessel, Innovation in late January. The vessel will carry up to four monopiles at a time, each one is 65m long, weighs around 800t and has a diameter of 8.1m.
