Beatrice Offshore Windfarm OTM 1 & OTM 2

Located in the Moray Firth, the Beatrice Offshore Windfarm project is Scotland’s largest offshore wind farm, comprising of 84 Siemens turbines and providing 588MW capacity since being fully operational in 2019, enough to power some 450,000 homes.

Wescott Industrial Services were contracted by Siemens to complete the two Offshore Transformer Modules (OTM) hook up works. We took on the scope of work on a target cost, reimbursable contract model with KPI conditions attached based on delivery and completion of the service. We completed the works to a very high standard and worked extremely closely with the Siemens management team to execute the works.

We had 55 POB working on the two assets at any given time over the period, which meant that our project management and logistics team had to ensure we were as efficient as possible at all times, including in period of inclement weather to ensure our client was receiving value for money. Our crew performed many alternative tasks and moved scopes around daily to ensure we were always working, this allowed us to complete the scope in a timely manner.

One of the main influences in Wescott being awarded this contract was our innovative approach in dealing with SWARF / Fly Rust, which is caused from hook up, commissioning, grinding and cutting activities offshore. Fine metal particles which are carried by the wind are transported to all structures on the platform, which causes many problems as they are generally hot when created an embed themselves into the coatings and rapidly amplifies and speeds up the corrosion process. The normal approach is to remove the coatings and reapply the protection system wherever it is affected, generally meaning a new coat is applied to the majority of the asset. Wescott, however, came up with a solution that allowed us to apply a product, leave it for 24 hours, scrub and high pressure wash the area to remove SWARF. This saved over 4000 productive hours offshore for our client, one month offshore and approximately £1,500,000.

All work carried out is supported by a three-year warranty.
