Since then, we have developed an ingrained understanding and knowledge of the practicalities and complexities of cable lay operations, to the extent that we are able to apply our knowledge to advise on the design and conversion of cablelay vessels.

Submarine Cable Installation Services

LOC Renewables’ operational-focussed submarine cable installation services include skidding moorings, and cable lay and pull, analysed in simulations using Orcaflex – the industry standard software applied to these operations.

We have also developed our own tool for automating the pre- and post-processing of cable installation analyses, allowing us to handle an increasing number of environmental cases, as requested by the Marine Warranty Surveyors (MWS).

Hydrodynamic Analysis, Shipyard Support, Project Management

Our capabilities cover a wide range of disciplines, from hydrodynamic and structural design analysis through to concept deck layouts and shipyard support and project management.

Such services include:

Concept design and design specification for cable lay vessel conversions including stability, powering and motions response calculations, machinery selection and DP (dynamic positioning) system layout, basic design, shipyard selection, detailed design review and stability and DP2 FMEA documentation
Hydrodynamic analyses for cable lay and pull-in operations, ranging from vessel skidding and survival mooring analyses to transportation and shallow water site-specific seakeeping RAOs analysis
Cable lay analyses including quasi-static and full dynamic analyses
Foreshore pull-in analyses
1st and 2nd end WTG/OSS cable pull in analyses
Seabed stability analyses
