Continued growth in global communications - the need for data and telecoms services - is putting hefty demand on international data and communications networks. The need for high-speed internet, from boardrooms to living rooms, has never been stronger.
The world relies on subsea telecommunications networks to meet this demand. Subsea networks use fibre optic cables to transmit data at high speeds with massive reliability levels, and today over 99 per cent of the world's data communications requirements are handled by these networks.
The cable laying process usually involves several phases, including installation, maintenance and jointing.
Installation can be undertaken in a variety of different fashions, but usually is limited to purpose built installation vessels, remotely operated vehicles (ROVs) and burial tools.
Due to cables being installed in both deep and shallow waters, the requirements for burial tools varies from project to project. Global Marine Systems operates a fleet of such vessels and equipment, designed for different cable laying situations and environments.
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 & 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.
Following successful cable installation, attention is turned to on-going maintenance. Because each subsea cable carries such vast amounts of data, a single failure in the cable network can cause a disruption in services. Failures are typically a result of damage caused by ships anchors and fishing trawlers, and thus generally occur near to a shore end.
Global Marine works with its customers, using cutting edge technology, to ensure rapid and efficient repairs are made in the event a cable incurs any such damage.
Global Marine Systems has a comprehensive background in engineering and subsea services. The company specialises in providing fibre-based data networks for oil & gas and telecommunications cable systems, continually leading in design and engineering around the world.
