The construction of high-voltage infrastructure is a specialism of Bakker Sliedrecht. After consulting with the client, grid operator and power supplier, the company advised the best solution for the high-voltage grid. After that the company ensured the engineering, the installation and the connection to the high-voltage grid.
"During these kind of projects we act more as a system integrator than as an electrical installer,” says Jan Grauss, Tender Manager Industry & Offshore Wind at Bakker Sliedrecht. ,,Now we can really show our specialism. You must be certified and employ specialized people to be allowed to work on high-voltage installations. For example, if you do not use the correct cables or components, you risk distorting the grid.”
Allseas Group is a world leading contractor in offshore pipeline installation, heavy lift and subsea construction. The new facility in Heijningen is located at a former shipyard with quay’s and is used, among others, for the training of its own personnel, for example in welding. Furthermore, large equipment and constructions for Allseas’ own ships and projects are manufactured and tested there.
The equipment used demands a lot of power. That is why a high-voltage installation is needed. Bakker Sliedrecht realized this through a large transformation station and multiple smaller sized transformer stations on the site. The project was completed in mid-May after a successful commissioning, after which the rest of the complex can be completed in mid-August. ,,The high-voltage installation is the lifeline of the site. Without power everything shuts down and nothing works anymore,” says project manager Fred Hordijk of Bakker Sliedrecht.
For this project, the electrical installation company acted as a subcontractor for low-voltage installation company Hoppenbrouwers Techniek, with whom it has previously worked on various projects. For Allseas, Bakker Sliedrecht previously supplied various electrical installations for energy generation and automation for the ships in its fleet of specialized heavy-lift, pipe-laying and support vessels.
The new facility in Heijningen is being built by Heembouw. Bakker Sliedrecht has also gained the contract for the service and maintenance of the high-voltage installation after completion, including installation responsibility.
