Offshore Instrumentation Cable

offshore-instrumentation-cable

Application:

Offshore Instrumentation Cables (also named communication cable or signal cable)are used for signal transmission on Drilling ships & drilling platforms ( jack up, semi-submersible), Production Platforms ( TLP, semi-submersible, SPAR, fixed platforms) and FPSO/FSO. These cables classified by DNV and ABS are vital in offshore platforms and ships, in order to control and drive sensors, valves, measurements devices, alarm systems.

Standards: IEC, NEK 606 :2009 & IEEE 1580 P

Cable Specification:

Mud Resistant:

The suitability of sheathing materials for use in areas in which the cables are exposed to drilling fluids is heavily dependent upon the type of fluid present. Each type of fluid contains additives which can have a deleterious effect on the sheathing material.

According to NEK 606, the mud resistant cables shall have a SHF Mud sheath that comply with the requirements in IEC 60092-359 for SHF2 and the below specified. The mud resistant cables shall be designed with sheathing compounds suitable for installation and operation in contact with MUD unless otherwise specified.

The MUD resistance test requirements for sheathing compounds SHF Mud are as follows:

Test fluid	Temperature	Duration
Mineral oil type – IRM 9O3	100°C	7 d
Calcium Bromide Brine (Waterbased)	70°C	56 d
Carbo Sea (oil based)	70°C	56 d

Oil Resistance

All thermoset sheathed cables shall be suitable for an oil production installation. The oil resistance properties shall be demonstrated by a test according to IEC 60092-359 SHF2.

Flame Retardance

The cables shall withstand the test specified in IEC 60332-3-10, -22, -23, -24, -25. Single,earth and bonding wires shall withstand the test specified in IEC 60332-1 or IEC 60332-2.
