Another Successful project to complete a successful year for N-Sea!

The consortium N-Sea - SeaRenergy complete another successful offshore retrofit solution campaign for TenneT

N-Sea Renewable and Utilities Services (N-Sea RUS), part of N-Sea Group, based in Dordrecht and Aberdeen, as part of a consortium with SeaRenergy Offshore Holding GmbH & Cie. KG based in Hamburg and Den Haag  have successfully completed a project to engineer, supply and install a retrofit subsea cable protection system (CPS) for an HVDC grid connection. 
SeaRenergy provided engineering services, developed the installation procedure, and assisted in obtaining the necessary approvals. N-Sea were responsible for the project management, procurement and installation of the CPS, including the supply of equipment, project personnel and vessel chartering. The retrofit installation needed to be performed subsea by divers under difficult weather conditions but as efficient as possible, in order to minimize downtime of the client’s grid access system.  Searenergy field engineers where present during the complete offshore operation in order to support the successful installation in accordance with the manufacturers, clients and BSH requirements.
The project required a collaborative way of working with the operator to ensure the correct solution was found and to secure the assets integrity before the winter season. Thereby, the consortium faced further challenges such as very short preparation time and various COVID-19 restrictions and repercussions. Moreover, the installation had to be performed during running operations to minimise the shutdown time. The consortium was able to manage these difficulties successfully.
Johann Philipp, Head of Engineering of SeaRenergy, commented on the project: “We are pleased to have been able to successfully complete the retrofit of the cable protection system together with our consortium partner N-Sea. It has been a challenging project due to the tight schedule for engineering, fabrication and installation works. In these circumstances the consortium’s history and past project experience proved to be of great value to the client.” 
Dale McDonald, Operations Manager of N-Sea Group, endorses this statement: “We are very proud to again demonstrate our abilities to work with our clients and find the correct solutions, in challenging circumstances. The way in which N-Sea and our Consortium Partner SeaRenergy were able to react to our Clients needs, is testament to our shared vision for a “first time right” way of working. It is the full intention for N-Sea and our partners, to continue to cement this effective way of working, which is benefiting our clients and making a real change in the industry.”
