SUBSEA CONNECTORS SERIES 22
7.3.1. General
The connector range series 22 is especially designed for long term subsea use under harsh
conditions, e. g. submarines. It can be supplied either singularly or as part of a harness assembly.
Series 22 connectors are only dry pluggable.
All GISMA connectors require the following acceptance tests during the terminations:
Mating test
Insulation Resistance test
High Voltage test
Continuity test
Cable terminations can be performed on-site or offshore by GISMA trained personnel where the
cable cannot easily be moved or transported. Each GISMA connector is fitted with a pin or socket
insulator which has been tested prior to despatch.
Termination of series 22 connectors should only be undertaken by trained personnel.
All series 22 connectors must be fitted with a mating connector or a pressure watertight protective
cap prior to subsea installations. Connectors must not be energised subsea unless coupled with
a mating connector or fitted with a pressure watertight protective cap, in order to prevent
electrolytic damage to the contacts when exposed to sea water.
All mild steel sealing interfaces shall be inlayed with Inconel 625, or similar, where no additional
protection can be provided. This is to prevent localised pitting of the interface. If not possible
grease the mounting hole and the supporting surface with corrosion preventing fluid (for example
Fluid Film) as a minimum.
Stainless steel (1.4404/ 1.4571 comparable to 316L/316Ti) or titanium grade 5 stab plate
connectors must be connected to the CP (Cathodic Protection) system at all times. If the
connector is designed with a fixed flange and screw mounting, an additional CP connecting would
not be required. Super Duplex stainless steel connectors should be isolated from the CP system
to reduce the possibility of hydrogen embrittlement.
Attention: The customer is responsible for the safe operation of the connectors and cable
systems. All necessary protective measures must be taken.
NOTE: Series 22 cannot be used for oil compensated systems or oil compensate hose
terminations.
For further technical information refer to the catalogue of series 22 or special drawings.
7.3.2. Live Mate / Demate
The series 22 range of connectors are designed to be mated / de-mated with POWER OFF.
