SUBSEA CONNECTORS SERIES 40
7.6.1. General
The hybrid connector range series 40 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 40 connectors are only dry pluggable.
All GISMA connectors require the following acceptance tests during the terminations:
Mating test
Insulation Resistance test
High Voltage test
Attenuation 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 40 hybrid connectors should only be undertaken by trained personnel.
All series 40 hybrid 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 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 40 hybrid connectors cannot be used generally for oil compensated
systems or oil compensated hose terminations. Special versions are available, please
contact our design department.
For further technical information refer to the catalogue of series 40 or special drawings.
