The Nautilus is an IP68 rated, Ex e enclosure manufactured from marine grade 316 stainless steel. One specific application for this enclosure is to ensure the protection of essential electrical connections within an FPSO turret system. Two Nautilus units are on an FPSO operating in the cyclonic region off the coast off Western Australia.

When severe storms are expected, the FPSO is de-mounted from its umbilical system. The vessel can then be at sea for several weeks with the turret area fully submerged. In this application, the enclosures were required to maintain their IP68 rating for the whole period. The Nautilus enclosure has been independently tested to maintain ingress protection at fifty metres for two weeks. Further testing confirmed one hundred metres of submersion protection for a period of five days.

Further details on the Nautilus can be found on the product page.
