ETA was established in 1995 by a group of project and technical specialists from BT Marine, formerly the cable installation and maintenance subsidiary of British Telecom. ETA has extensive experience providing support on cabling projects in the telecoms industry, offering services from total project management to 'one-off' consultancy assignments, design work, planning, and technical studies.

The founding group is joined by project managers, engineers, marine specialists and equipment technicians, providing an unparalleled depth of independent technical expertise in the field of subsea cables. Since 1995, all of ETA’s key staff have been involved in telecoms projects worldwide.

Alongside our involvement in telecoms cable projects, ETA’s expertise has been acquired from their background in the installation and maintenance of subsea cable in the traditional fields of power cable, or offshore oil and gas projects as well as from their extensive involvement with offshore renewables.

A sample of ETA’s varied experience in the Telecoms market can be found below.

Power Cable Clients and Project Examples

Fibre optic cable system
IMEWE (India-Middle East- Western Europe) cable is an ultra-high capacity fibre optic cable system which links India and Europe via the Middle East. With a total length in excess of 12,000km the cable lands in 8 countries and is owned by a consortium of 9 leading telecoms companies.

ETA acted as the joint chairman of the route working group: chairing meetings between multinational clients and the installation contractors; supplying all onsite client representatives from the survey through installation; and providing engineering expertise into route selection and protection strategy.
Vodafone Malta:
Fibre optic cable system
The Vodafone Malta-Sicily Cable System is an un-repeated fibre optic cable system providing a 2 x 2.5Gbit/s link between Malta and Sicily. The system was constructed by Alcatel Submarine Networks under a turnkey contract. ETA were appointed by Vodafone to act as Purchaser Representative, providing factory and marine QA services, and technical and project management consultancy.

ETA provided technical and value audits and guidance during the planning and engineering of the work. During critical offshore operations ETA representatives oversaw the work to ensure compliance with contract and agreed procedures and an ETA systems engineer witnessed system commissioning and provided key advice to Vodafone during the acceptance and confidence trials of the system.
PEC/Level 3:
UK-France telecom cables
ETA managed the installation of two UK-France telecoms cables for Alcatel Submarine Networks (ASN) on behalf of CTC Marine Projects from project awarded through to completion. Despite significant challenges (including hard sea beds, demanding burial targets, and very tight deadlines), the installation of the PEC and Level 3 projects was carried out over a two and a half month period and was completed on time and within budget. Burial targets were also achieved throughout.

As well as the Project Management for the cables ETA also supplied the vessel lay spread including: twin cable tanks, cable pathway, stern chutes, jointing and testing container, and an integrated cable lay system enabling all system parameters to be monitored at various locations including the vessel bridge. During the installation ETA also provided many of the key staff including the Offshore Superintendent.


ETA were selected by the system supplier, KDDI-SCS, to provide support in the marine planning and installation of the European segments of the extensive Tat14 system that links the United States to the United Kingdom, France, The Netherlands, Germany, and Denmark.

ETA provided a project manager to oversee technical, schedule, commercial and quality issues, and technical specialists as required. ETA provided a flexible and cost effective service - the original small team was expanded to around 20 specialists onshore and offshore during the peak work phases. Work included: Project Management support, burial feasibility / cable protection, European Continental Shelf expertise, cable engineering, installation QA, Offshore Representatives, and logistics.

A multi-owner project, ETA also assisted with the international client interfaces at regular progress meetings.
