Extensive analyses and inspections in 2013 revealed a need to reinforce the Njord A platform structure. To be on the safe side, Statoil opted to keep production shut down until the reinforcements were in place.

"We have extended Njord's lifetime by improving recovery on the field, and by finding more oil and gas in the area. The Njord A platform has been with us the entire time, and we want to make sure that the structure can withstand the loads it will be exposed to," says head of Njord operations Arve Rennemo.
The work that has been done through the winter and spring has strengthened the structure, so the platform can resume production. The work of reinforcing the structure has mainly consisted of bracing the primary beams and struts, and increasing the length of the secondary beams under the platform.
The long-range plan is to further bolster the platform to prepare it for future drilling operations and an extended lifetime on the Njord field.
"Njord A will produce oil and gas until the summer of 2016, after which it will be taken to shore for additional upgrades which will allow us to use the drilling system on board, and prepare it for many more good years of service on the Norwegian shelf," says Rennemo.
Statoil also has studies in progress to assess how the Njord area and the Haltenbanken area in the Norwegian Sea can be further developed. The Njord A platform has been in production since 1997.
