ETA’s vessel layout skills and experience are considerable. Designing vessel spreads for a range of purposes ETA can provide all necessary services including design, layouts, equipment design and modification, class approval, and the engineers required to mobilise the spread.
ETA’s vessel layout skills and experience are considerable. ETA has developed spreads for a range of purposes across all the major subsea cable markets and can manage everything from design, to procurement and mobilisation.
We have converted telecoms cable vessels to Power Cable/Umbilical layers, including the design of deck layout and full manufacturing drawings for modifications to cable tanks, tank cones, coiling arms, gantry, deck quadrants, cable engine seats and chute.
We have prepared deck layout designs and class approval for fitting of large cable trenching ROV to ‘flatback vessels’ and supplied the mobilisation engineers.
In the offshore wind market we have provided deck layout design and class approval for barges to be used as cable lay vessels for installation and plough burial of export cables including design and full manufacturing drawings for equipment seats, cable tank, gantry, coiling arm, and deck quadrants etc. Mobilisation engineers were also supplied by ETA.
ETA have also provided deck layout and detailed design including class approval for inspection ROV and specialist mine disposal equipment. Below you will find a small sample of ETA’s past experience.
