3. Health and safety
It is the intention of Deepwater Corrosion that all test and inspection procedures are carried out in
a safe manner in accordance with the Health and Safety At Work Act and any other relevant leg-
islation. If required by the client, Deepwater personnel will attend any site safety induction courses
before carrying out work on-site.
4. Installation procedure
4.1 Dive spread
4.1.1 When used with diving operations, assemble a cable with a SEA CON
®
RMG-3FS connec-
tor at the subsea end. In our experience, the most suitable cable is the four (4) conductor armored
spiral comms cable used by most divers for diver communications; it has two twisted pairs and
is very rugged. A whip with this connector is provided with the probe and should be soft-spliced
onto the end of the comms cable (see Fig. 1). Ensure that the connection is taped back to the
armored wire to provide strain relief to the subsea connector.

4.1.2 If required, Deepwater Corrosion can provide a complete assembly on a 500-foot-long
umbilical cable.
4.1.3 The appropriate length of cable should be married into the dive hose, leaving 4-6 feet (1.2m
– 2m) of slack at the subsea end and at least 50 feet (15m) at the topside end. Always install
the dummy plug on the connector when the probe is not attached.
4.1.4 The topside end of the cable will be run to the dive control area along with the platform
ground cable and any ground from pipeline risers. The connections can be made to a pair of dig-
ital multimeters (refer to g. 6, wiring schematic for diver-assisted platform survey.)
