Offshore Supervision

Information

Client: C-Power - SENVION

Location: Belgium Nord See

Power: 325,65 MW

Construction: Feb08 - Jul13

Wind turbine: Senvion 5 x 5M and 48 x 6M


Description

This challenge was presented by "C-Power", a consortium of Belgium and other European companies. The project is located in the north see approximately 30 km north from Oostende where the onshore site was based. The site water depth is between 12m and 27,5m and the occupied area is 19,84 km2. The task consisted in supervision and trouble shooting of the commissioning works with special emphasis on communication, radar & navigation signals, webcams, documentation and field work instructions.

Challenges

In generally the see environment the whether and the accessibility of the turbines by itself was a challenge. The other main challenges in this project were methodology, onshore-offshore work organization and site coordination. The coordination of works was also a challenge as team shifts demand constant training and tight supervision of works. Finally the challenge of the industry being still inexperienced, balancing between performing activities onshore (downside of having a long waiting time for transport, installation etc) or performing the activities offshore (later on but expensive and more risky).

Solutions

New methodology and works organization needed to be introduced to cope with the works onshore-offshore. Everything needed to be well prepared and double checked, personnel needed constant training before being shipped offshore. Because of work shifts and training needs on the teams (installation, commissioning, etc.) the supervision and training activities needed strong reinforcement.
