ETA’s Design Engineering team can bring skills and knowledge acquired on wide ranging design projects around the world, as well as from designing ETA’s own range of subsea equipment, to address your own bespoke requirements.
Project Engineering services include
ETA, through our in-house research and development projects have gained significant knowledge of key areas of marine design including: surface and subsea machinery; subsea control systems (hydraulic and electric); termination and connection solutions; quadrants; cable hang off systems; cable recovery systems; submerged water jetting; and underwater track systems.
Our well qualified and experienced staff derive technical requirements, generate concept options, optimise viable solutions, create successful designs, and then produce drawings or detailed procurement specifications for manufacturing.
Where required we can manage construction, on behalf of clients within the UK or overseas. For further information call using the number below or email via our contact page.

Marine & Subsea Design Clients and Project Examples
.
The quadrant had an MBR of 3 m and allowed the second end cable to be run around the deck to minimise lay past. The quadrant was then designed to run down the deck on rails before going over the chutes and finally laying the cable safely on the seabed during the pull-in. The quadrant had to meet the additional challenge of being slim enough to fit in a tight space below a mezzanine deck. The quadrant has since been re-ordered.
Termination
The CAT device as delivered by ETA allows cable ends to be laid down for a period ofup to four years, fully sealed to prevent water ingress, and will allow the cables to berecovered at a later date and fitted straight to parent devices by means of a bolted flange connection.
The power cores of the cable are sealed with live end sealing to allow for integrity testingduring the 4 year abandonment period.
Pitch Control Motors
ETA’s design engineering team produced the overall design and procurement specifications for all items of equipment and interface requirements; and subsequently, the Procurement of main components, fabrication of interfaces and FAT at ETA’s premises in Romsey.

Due to the use of a basket cable load strategy, ETA’s design had to meet the unique requirement of being capable of removal and re-installation in a short time window. ETA designed the gantry, powered quadrant, and cone; as well as the dockside seat to be used when the gantry was removed.
The design ETA provided was a great success with removal and reinstallation times well below specified maximums.
