SUBSEA TITANIUM CONNECTORS SERIES 16
7.2.1. General
The series 16 sizes 3,4,5,6 ranges of connectors has been developed for long term reliable signal
and low power control system applications associated with offshore installations.
The long term watertightness of the mating area at the signal connectors series 16 (contact-Ø 1,5
mm) is achieved by using a patented, conical sealing system at each contact, a lip gasket and an
O-ring seal.
NOTE! These connectors are not underwater mateable.
A part of series 16 connectors are especially designed for oil compensated systems and are
pressure proof from both sides.
NOTE! Please make sure to use the appropriate connector in your system.
For further technical information refer to the catalogue series 16 or special drawings.
Connectors are usually supplied with dust caps. The dust caps need to be removed prior to mating
the connectors.
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.
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 contacts. Over exposure will increase the risk of
corrosion damage or marine growth on the contact surfaces of the pin contacts. This could lead
to damage to the seals and insulation within the socket contacts.
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 16 range of connectors can be supplied either singularly or as part of a harness
assembly. All series 16 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 16 connector has been mated,
