The tube is operatively conectu00e3vel ascending sub between a platform and a superfu00e3u00adcie subsea equipment. The unit of shutter includes a shutter housing, and at least one shutter.The accommodation of the shutter posicionu00e3vel around a unit telescu00e3u00b3pica. The unit telescu00e3u00b3pica operatively connects the ascending tube submarine with platform superfu00e3u00adcie.The shutter (s) (s) - (su00e3u00a3o) posicionu00e3vel (s) over a superfu00e3u00adcie internal shutter housing, to form a vedau00e3u00a7u00e3u00a3o with unit telescu00e3u00b3pica and include a plurality of segments shutters.Each of the segments shutters have male connectors at each end thereof and fu00e3u00aamea harmoniously conectu00e3veis to male connectors and fu00e3u00aamea of another one of the segments to form a conexu00e3u00a3o of vedau00e3u00a7u00e3u00a3o between them. The conexu00e3u00a3o of vedau00e3u00a7u00e3u00a3o defines a leak path nu00e3u00a3o linear, whereby the leakage of fluid between the plurality of segments is held.
