Home>Projects>Load testing of gas turbines for Equinor
Our customer Equinor requested us to execute a comprehensive load test before installing gas turbine generators on their offshore vessel. This is the largest load test we have delivered in Norway ever.
At Kværner Stord, two 11 kV / 40MVA gas turbine generators are under construction.They will supply power to Johan Castberg FPSO, located at the Johan Castberg oilfield which is situated 240 kilometers north of Hammerfest (Norway). We executed a load test to secure full operation of the gas turbines before installing them on the vessel.
The HV transformer and load bank package can generate up to 50MVA load. This equals the power consumption of a city with 65 000 residents. A 2500A HV switchgear with a high-level shortcircuit performance is custom-built in a 20ft container.
The delivered package includes all ancillaries that distribute supply from the high-voltage grid via 8x 11kV–400V transformers, HV and LV cables, cable ramps, cable ladders, LV switchgear and distribution boards, as well as UPS to ensure power supply of all critical systems.

Red-D-Arc Welderentals leases welders, welding positioners and welding-related equipment. They required an offshore power solution during the decommissioning of gas platforms Kinsale Alfa and Kinsale Beta, at the South coast of Ireland.
Heerema is a company specialised in the engineering and fabrication of complex structures for offshore oil & gas and energy-related industries. Delivering on-time and with high quality and safety standards is firmly set in their DNA.
Equinor will start the Johan Castberg oil field in the Barents Sea in 2023. It will consist of a seabed field and an anchored production ship – a so-called FPSO. The ship travelled from Singapore to Norway and we were challenged to design a temporary power solution for this voyage.
