Cable Testing & Test House

Before laying cables, proper development and testing must be undertaken in order to ensure reliability, and cable jointing is one of those highly specialised requirements.

A cable joint is essentially what it sounds – the connection between two pieces of fibre optic cable.

As each cable is unique in its design, based upon its specific requirements for speed and capacity (the amount of data it carries), and based also upon its use (a trans-oceanic network, a regional network, a domestic festoon network or even connecting offshore oil AND gas platforms), each joint requires a skill set to ensure it meets the design needs of the cable.

Global Marine Systems operates a test facility that continually raises the joint standards for the entire industry.

Test Facility

Housed at the head office in Chelmsford, UK is Global Marine’s industry leading Test Facility, over recent years the site has become the ‘go-to’ place for cable manufacturers as well as other industry organisations wanting reassurance that their product is suitable for the harsh marine environment that it ultimately has to operate in.

Before a cable, joint, rope, hawser, repeater or other item of subsea equipment can be deployed, there must be an assurance that it can be laid and operate safely and satisfactorily under extreme maritime conditions.

Global Marine offers a complete range of rigorous mechanical, electrical, environmental and optical test facilities for the marine industry which simulate marine deployment and oceanographic conditions.

These include tensile testing (up to 100kN), torsion, high voltage and pressure testing – to internationally agreed standards and with full monitoring and data logging, both electrical and optical. Pressure testing can simulate the conditions at the deepest point of the ocean; high voltage testing can simulate electrical surges, and the round the sheave tests simulate all types of deployment from vessels. Following testing, concise reports are issued together with test certificates.
