Feasibility Studies

P2 Offshore Consulting has vast experience with subsea cable system design. Our feasibility studies include detail hazard assessment, if applicable, of the proposed cable system, researching natural and man-made terrestrial and marine hazards, meteorological, oceanographic and earth processes, seabed topography and sediments, maritime industries, environmental impact on flora and fauna, cable fault histories and interaction with marine protected areas and coastal/underwater archaeology.

 

Every aspect of the feasibility study is researched in detail. We provide the customer with a clear concept of the level of risk associated to the cable system and our engineers provide innovative solutions to mitigate that risk for the typical 25 year design life of the subsea cable.

 

Our company uses a wide range of academic and commercial datasets to build a comprehensive resource of the factors which may affect the life of a proposed submarine cable. This knowledge base is supported by our comprehensive experience of cable installation (ploughing, jetting and trenching, shore end landings, post lay inspection and burial and deepwater surface laying) to give the customer complete confidence in the proposed cable system route and the risk factors associated with it.

 

MakaiPlan GIS software is used as a cornerstone of the feasibility study process, using the GIS functionality to import various layers of data to assist with cable system planning. This includes Admiralty and NOAA maritime charts, bathymetry databases, sediment data, oceanographic data, earthquake locations, existing cable databases and satellite imagery. As each dataset is reviewed, the cable system route is continually modified until an optimum route has been determined.

 

P2 Offshore Consulting has access to expert engineers who assess landing points for undersea cable systems and have extensive experience of the world's existing cable landings. As capacity at these landings becomes critical, engineers assess the suitability of new cable landings from the perspective of safe and effective installation, ease of permitting, connection to the customer's infrastructure and long term cable maintenance.

 

Feasibility studies also comprise of the commercial evaluation of a proposed cable system, designing a route from first principles based on the customer's requirements.
