A B S T R A C T MEANS FOR SEALING A GAP AROUND A CONDUCTOR PIPE Conductor pipes on an offshore drilling and production platform pass through openings in the decks of the platform. The openings are to be sealed off to prevent spreading of hot and/or noxious fluids from one deck to another. The sealing means consists of two annular elements arranged around a conductor and connected to the conductor and the deck, re- spectively, thereby forming an annular trough in which one of the elements protrudes. The trough is filled with a flexible substance, such as a silicone foam.
