4. UNPACKING
Remove wrapping material taking care to inspect for any surface damage or items that may have
become separated from the conn
ector, such as ‘O-ring' seals. Do not use a knife to cut the wrapping
material, as this may cause damage to any elastomeric parts of the connector. Do not remove any
kind of protection caps until connectors are ready for installation. On removal do not allow the cables
to drag over the edges of the packing crate.
5. STORAGE
Short Term Connector Storage
Prior to installation the connectors are sensitive to environments where grit and dirt are present.
To prevent ingress of the above, they should be stored in a clean dry area and be protected by
bubble wrap or similar wrapping and packing material. Protective caps must be fitted if supplied.
Long Term Connector Storage
The connectors must be stored in a clean dry area and be protected by bubble wrap or similar.
Suitable protective caps must be fitted, and the storage temperature should be ideally between
+5°C and +20°C. For short times and during transport storage temperature can be between -40°C
and +70°C. Humidity of the store room should be below 75%. Very moist or very dry conditions
should be avoided. The connectors should be protected from sunlight and artificial light with a
high ultra violet content.
The connectors should not be allowed to come into contact with solvents, oil, greases or any other
semi-solid materials.
If storage time is longer than 2 years, outer o-rings have to be replaced prior to installation.
6. Jumper handling and mounting
Jumper handling
GISMA connectors can be delivered as part of the jumper assembly. All terminated connectors
are delivered with dust caps for protecting the contacts and the insulator against damage and
dust.
These caps have to be removed before subsea usage.
Before mounting inspect the jumper and especially the cable for damages and debris.
Lightly grease the locking threads of the receptacles, pressure hull penetrators and the through
bulkhead receptacles e.g. with GISMA-FETT LP 430 (strongly recommended at stainless steel and
titanium threads).
After mounting the cable has to be fixed closed to the structure (first fix point 500 mm behind the
connector
’s endbell and then every 500 mm) to prevent movement and turning of the jumper
cable.
Take care that all connectors are correctly mated and locked with the correct mounting torque or
protected by pressure watertight protective caps before going subsea. For defined mounting
instructions refer to the different connector series and special jumper drawings.
Prior to installation the connectors are sensitive to environments where grit and dirt are.
