Sealing Technology

Seals for door frames on board a marine vessel Applicant: Marine Systems Technology Ltd, UK A watertight door system for a marine vessel is described. It comprises a door and a door frame with a threshold. The frame is adapted so that it can be connected to the bulkhead and has two sides, a top member and a floor trough. The latter has a lid to close the trough at least when the door is in an open position, so that the floor is rendered substantially level through ̅iÊ`œœÀÊ>«iÀÌÕÀi°Ê/…iÊÃi>Ê“>ÞÊiÝÌi˜`Ê>œ˜}Ê the lid (in the case of a pivoting door) or in the trough, in the case of a sliding door.
