The rapid four-week installation of an ultra-lightweight fire insulation blanket from Morgan Advanced Materials is providing extensive thermal protection for three separator vessels on the Statoil Mariner offshore platform.
Morgan’s FireMaster vessel fire protection system is being used to maintain structural integrity of the separators against jet and hydrocarbon pool fires. Fire protection is crucial because these separators contain hydrocarbon inventory, which can become additional fuel to a fire in the event of structural failure. Thermal weakening and failure occur when the walls of the separator are heated by the exposing fire case. With increased temperature of the steel vessel shell, the applied stress on it increases, causing rupture. Morgan’s FireMaster protection ensures that the steel shell temperature does not reach breaking point as temperatures surge.
The design fire scenario stated that the separators should be able to withstand fire loads of five minutes of jet fire at 350w/m2, followed by five minutes of jet fire at 250kw/m2, and an additional 50 minutes of hydrocarbon pool fire. Morgan’s FireMaster solution was considered the most effective and easy-to-install option for the project, which had to be completed within the space of just one month.
