PFP helps maintain operations in the Arctic
Operating in arctic temperatures, our customer has three gravity-based structures (GBS) with LNG and condensate storage in the hull. Each structure needed protection to ensure it would remain operational and exceed health and safety requirements. We recommended that the GBS have winterisation and acoustic protection that met fire and blast criteria and would exceed health and safety requirements.
The highlights
40-year design life
Our solutions are designed and tested to have a 40-year operational life with zero maintenance requirements.
50 dB noise reduction
ContraFlame® MS400 delivered a better noise reduction than the 45 dB project specification.
2 hours hydrocarbon fire protection
ContraFlame® C50 had a 239 °C temperature rise after two hours. This significantly exceeded the 500 °C project specification.
Solution
Each GBS was constructed from concrete with dimensions of 330 m, 152 m and 30 m. As well as the demanding operational requirements in a high risk environment where daily temperatures can be as low as -52 °C, the project had a proposed operational life of 40 years. On top of this, any solution needed to be zero maintenance in that time.
We worked with the project team to show how a combination of ContraFlame® MS400 and ContraFlame® C50 systems would meet or exceed all the project specifications.
Results
ContraFlame® MS400 was specified for the undersides. ContraFlame® C50 was specified for the steel structures. Both were developed for a 40-year design life in extreme environments.
ContraFlame® MS400 was 670 tonnes lighter per GBS than alternative solutions. This was important because they were moved into position via a shallow river estuary. Also, its 50 dB noise reduction when applied to an 8mm steel deck far exceeding the 45 dB specification.
ContraFlame® C50 was ISO tested and proved at -52 °C with no failures for tensile strength, impact strength, shearing, density or flexural performance. In hydrocarbon fire testing it had a 239 °C temperature rise after two hours, exceeding the 500 °C specification.
