摘要:
The present invention relates to a method for determining an operational state of a subsea connector unit (10, 10a, 10b), wherein the method comprises at least the steps of: Providing at least one operational value (12) and/or a plurality of operational values (12) of at least one operational parameter (14, 16) describing a specific operational condition at at least one selected location (18, 20) of the subsea connector unit (10, 10a) and comparing the at least one provided operational value (12) and/or the plurality of provided opera- tional values (12) and/or at least one derivative (22) derived from the at least one provided operational value (12) and/or at least one derivative (22) derived from the plurality of provided operational values (12) with at least one predefined reference (24, 24'; 26, 26') and thus determining an operational state of the subsea connector unit (10, 10a, 10b) on the basis of the comparison. The invention further relates to an assembly (38) for monitoring an operational state of a subsea connector unit (10, 10a, 10b) and to a subsea connector unit (10, 10a, 10b).
摘要:
A subsea electrical connector or electrical cable comprising a conductor (2), an insulator (4) coaxial with the conductor; and at least one of a volumetric compensating diaphragm (15) located radially outwardly of the insulator, or a termination boot (40); wherein the diaphragm or termination boot comprises a compound layer, the compound layer comprising a graphene nano-platelet additive incorporated (23) into a cross-linked polymer matrix to produce a polymer composite.

A pressure compensator for compensating volume variations of a medium is provided. The pressure compensator has a first compensator part and a second compensator part. The first compensator part encloses a first volume and the second compensator part encloses a second volume. The first and second volumes are in flow communication. The first compensator part includes a first bellows portion and the second compensator part includes a second bellows portion. A moveable element is further provided, to which the first bellows portion and the second bellows portion are mechanically coupled such that movement of the moveably element along a predetermined axis results in the compression of one of the bellows portions and in the expansion of the other of the bellows portions.

The present invention relates to a connector part (10, 10a) of a connector unit (12), wherein the connector unit (12) comprises a male part (14) and a female part (16), comprising at least one volume compensating arrangement (18, 18a) with at least a first flexible layer (20, 20a; 22, 24, 24') and at least a first chamber (26, 26a), wherein the at least first flexible layer (20, 20a; 22, 24, 24') at least partially encases the at least first chamber (26, 26a). The at least one flexible layer (20, 20a; 22, 24, 24') comprises at least one thermoplastic material.
