Cable Route Engineering Skills and Burial Assessment 


Colin Poat has wide experience of geo-survey and geotechnical techniques used in cable route engineering design and burial assessment.  As a highly qualified surveyor, engineering geophysicist and geotechnical engineer he has had extensive exposure to the wide range of potential burial equipment on the market; its capabilities and limitations.  Experience over the years has been gained by working alongside colleagues at BT Marine, Cable and Wireless Marine, Global Marine Systems, TE SubCom, Alcatel-Lucent, Huawei Marine Networks, Red Penguin Associates, ABB, BICC amongst others.  Cable route engineering experience including substantive elements of burial feasibility assessment has been gained by working on such cable projects as; SMPCS2, ACS, Nemo Link HVDC, BT Highland and Islands, NorNed HVDC, Celtic Array, BritNed HVDC, Silphium, East-West Interconnector HVDC, EIG, Unity, Danice, Med-Link, SMW4, GWEN, CAMring, Nava1, MAC, I2I, EAC2, Dishnet, Apollo, GlobaLink, Flag Atlantic, Flag, China USA, SMW3, Western Link HVDC, Atlantic Crossing, INELFE Biscay Gulf Western Interconnector HVDC, Walney Wind Farm Extension HVAC cable crossings, Aquind Cross-Channel HVDC, SSEN Orkney to Scotland, Jupiter (Japan to USA), GreenLink (UK-Ireland) HVDC, Havhingsten UK-Ireland, IFA2 (cross channel), 2Africa (Mediterranean), Eastern Link Lot 1 HVDC (Torness to Seaham) and other projects ongoing...

No two cable related projects are the same; no two cable installers are the same.  The skill is to take best practices from each cable project and learn from them. The importance of working with others cannot be underestimated; often one of the best maxims to apply is 'you don't know what you don't know'.  The emphasis in all works conducted by CP Geo-Services Ltd is integrity and professionalism.
