Power Modules Gaz de FranceMichel Jansen
Around the end of February, three so-called Power Modules and an HVAC module for Gaz de France were commissioned by Hertel and fully tested at Hertel at the former Verolme yard in Ridderkerk. Several of these modules have been built by Vageri in collaboration with Hertel in the past, Gaz de France Netherlands has again chosen the well-proven Power Module concept. And this time no less than three offshore platforms at the same time. Namely for the D18-A, L5-AD and the Q13-1 platform. The Q13-1 module was slightly larger in size, and a separate HVAC (Heating Ventilation Air Conditioning) was built for this platform.
How does it work?
The technical “nerve center” of a new platform (the Power Module) is built and tested as completely as possible, while at the same time the rest of the platform is being built and tested at a shipyard elsewhere. When the Power Module is ready, it is transported in its entirety to the shipyard and placed on the platform and welded to the structure. Subsequently, the cabling is transferred from the platform to the relevant components in the Power Module. By working in this way, time is saved during construction, but also for the test phase of the platform before it goes to the sea.
In a Power Module of this concept there are, among others, a .; three micro-gas turbines, an (emergency power) diesel generator, diesel-driven fire extinguishing water pump, the electrical distribution system, the control system, ventilation and heating system, batteries, battery chargers and rectifiers.
