ETA personnel have been involved in projects all across the world from the UK-France Interconnector to inter-platform cabling in the Niger delta.
In the power market, product cost, handling criteria, dimensions and weight strongly influence the economics of route selection, installation and planning. Similarly, the economics and repair timescales of power interconnectors demand a high level of system security.
As such ETA’s engineering capabilities find application ensuring correct selection of route and installation tools to achieve optimum burial and protection. Our understanding of system options and costs enables us to guide the development of cost-effective solutions.
Alongside experience in the power market, ETA’s expertise has been acquired from their background in the installation and maintenance of subsea cable in the traditional fields of telecom, or offshore oil and gas projects as well as from their extensive involvement with offshore renewables.
This breadth of expertise has been gained through the management of complex subsea cable projects combined with practical ‘hands on’ installation experience all of which is supported by a strong engineering team using up to date cable planning and modelling tools.
For more information on ETA’s products and services give us a call on:
Working for EPC contractors ABB, ETA provided Project Management and Engineering Support across the whole project providing: route planning based on the hi-res pre-lay survey; installation planning; specs for tenders; tender appraisal for 9 sub-contracts; managing day to day installation including QHSE; commercial disputes etc; face to face meetings with clients to resolve technical and commercial issues; and contract variations etc. ETA also supplied Client Representatives for the project.
Power Cable Installation
The project was the first installation of a DC cable link between an offshore Wind Park and the grid.
ETA provided the Deputy Installation Manager for the project; offering extensive Project Management support including specifications for tender, management of the tendering process, sub-contractor management, and client coordination.
ETA’s earlier engineering work on the Team Oman during the BritNed project proved instrumental in the success of the project.
Working through the lead installation contractor, Global Marine Systems, ETA provided a range of design and engineering services to the project including: installation analysis for both the main cable lay and shore landings;
Jointing and Repair
ETA were contracted by Bohlen and Doyen to develop procedures and a detailed design for installing a joint in the dual core FMI Cable Section from the C/S Skagerrak. In addition this procedure was to be applicable for a general 50m repair.
