SUBSEA CONNECTORS SERIES 34
7.4.1. General
The series 34 range of connectors has been developed for long term reliable signal and low power
control system applications. The watertightness of the dry mateable connectors series 34 is
achieved by using O-ring seals. The insulator inserts are longitudinally watertight.
For further technical information refer to the catalogue of series 34 or special drawings.
NOTE!
These connectors are not underwater pluggable.
Connectors are usually supplied with dust caps. The dust caps need to be removed prior to mating
the connectors.
The connnectors 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.
If the connectors are to be left unmated in seawater for any length of time, pressure watertight
protective caps must be used to protect the connector interface.
The appropriate test connector must always be used to make electrical contact during testing.
UNDER NO CIRCUMSTANCES
should a foreign object (such as a screwdriver, test probe or
crocodile clip) be used as a test connection as this could damage the seals and insulation. Such
actions will invalidate the warranty of the connector.
Attention: The customer is responsible for the safe operation of the connectors and cable
systems. All necessary protective measures must be taken.
Test connectors or free touchable connectors with metal shell must be connected to the
earth conductor.
The series 34 range of connectors can be supplied either singularly or as part of a harness
assembly. All series 34 connectors require the following acceptance tests during termination:
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 series 34 connector has been mated,
hydrostatically tested (applies to receptacles only) and electrically proven prior to despatch.
Termination of these connectors should only be undertaken by trained personnel.
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.
