ETA have the varied cross market expertise to offer high level input and innovative solutions in new areas, and in smaller or less developed markets.
As well as in established areas, ETA’s knowledge and skills have been utilised in several emerging, or smaller markets for submarine cable. Notable areas in which ETA have worked include Wave Power, Marine Science and Seismic Cabling. Some details of ETA’s experience with in more uique markets are given below.
ETA were early entrants into the Tidal Energy and Offshore Wind Markets working on the UK’s first major offshore wind farm at North Hoyle, and the connection of the first Tidal Turbine to the UK national grid with OpenHydro at EMEC.
In these areas, ETA have been responsible for many key innovations vital in bringing technologies from development stages to commercial exploitation.

Specialist and Emerging Market Cable Clients and Project Examples





Wave Energy Joints

Working closely with the generator owners and EMEC, ETA took cable samples of the static cable for testing; conducted a design review of the proposed new joint; and witnessed the testing and trial assemblies. Following this, ETA provided the Client Representatives for EMEC during the subsequent successful installation.
Cable Recovery

ETA provided the design and fabrication drawings for the deck spread, including cable stowage arrangement, and equipment sea fastening; as well as the selection of the specialist handling equipment for the unique high volume cable recovery and recycling vessel. A principle challenge was optimising the recovery and offshore operation to match the post recovery onshore recycling and transportation processes.
LORI & LORI II

Following this, ETA conducted the design and mobilization of shallow water trenching spread for the cable and provided the Offshore superintendent for post lay burial of cable from beach to 25 m water depth. The success of the LORI project lead to ETA being commissioned for further work on the spread for the LORI II system that followed.
Mapping:

At the request of OHM ETA conducted a review of the power distribution system for their existing DASI III system which included the design of an upgrade to the high voltage (HV) system from 1.8 kV to 4.5 kV. ETA then designed and supplied the HV Line Insulation Monitoring (LIM) system for this upgrade.
Building on the success of the DASI III system OHM was constructing a new system, DASI IV. For this project ETA were contracted to supply a variable HV (up to 4.5 kV) power distribution system including control monitoring and protection circuits. This was fitted into a fully lined and air conditioned 20 ft ISO container which was subdivided to provide a storage space at one end.
