Firefighting solutions

Case: Vineyard, US

Firefighting for Vineyard Wind 1

800MW transformer platform project for a wind farm, located off the coast of Massachusetts US.

Active fire protection consists of one self-expanding foam system, two large inert gas systems, and one DIFF system.

The foam system is object protection of the oil-filled equipment, HV transformers, HV shunt reactors, and EATS. Inert gas systems are full flood and protect all the electrical utility rooms. 

The DIFF system is propelled with Nitrogen and covers the helideck in a water/foam mix within 15 seconds.

Case: Arcadis

Arcadis Ost substation

Offshore transformer platform for a wind park located off the coast of Germany. The project consisted of design, procurement, installation & and commissioning of active fire protection systems.

On the Arcadis OST platform were installed stand-alone Inert Gas systems for electrical utility rooms, a fully redundant premix foam system for all oil-filled equipment HV transformer, shunt reactor & and EAT. Furthermore, a pump-driven, non-popup DIFF system protects the helideck.

Case: Ørsted

Hornsea Project One

Design and EPCI of firefighting systems for the Hornsea Project One offshore substation in the UK sector (2016-2018). Transformers, auxiliary transformers and shunt reactor rooms are protected by a stand-alone foam system (fluorine-free foam). All other rooms requiring fire protection are protected by an argonite inert gas system.

Case: Bladt Industries and Vattenfall

Sandbank

A very large offshore substation project as far as the scope is concerned since high voltage systems, SCADA and fire protection are part of this project. The project phases include engineering, procurement, installation and commissioning of topside equipment in the German North Sea. The project was completed in August 2016 after which intensive testing and training took place.
