All information contained within this section is generic. Where customer or project-specific
information is required, please refer to the relevant project specification or scope of supply.
For further technical information refer to the catalogues of the different series or special drawings.
Note: It is important to isolate and earth prior to disconnect in order to remove any stray
charges in the system. If left, this can induce corrosion on the exposed pins once the plug is
removed.
The connector shall have the following periodic maintenance checks:
Examine the connector for signs of damage.
Check the locking sleeve, these shall be tight, if loose refer to assembly instruction
for torque values, where appropriate.
SUBSEA CONNECTORS SERIES 10
7.1.1. General
The series 10 sizes 1 to 7 range of connectors has been developed for long term reliable signal
and low power control system applications associated with offshore installations. The underwater
mateability of the range of signal connectors series 10 (contact-Ø 1mm and 1,5mm) is achieved
by using a patented, conical sealing system at each contact and a lip gasket.
For further technical information refer to the catalogue of series 10 or special drawings.
The connector range series 10 comprises standard
power connectors
for high voltage and high
current application as well.
NOTE!
These connectors are not underwater pluggable. Please ask
for detailed product information.
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.
