PTC 14 O&M Overview Final

  1. 1. Title Submarine Cables: O&M and Cable Maintenance PTC – 19 January 2014 Dean Veverka Director Networks & Vice President Operations Southern Cross Cables Ltd. ICPC Vice-Chairman © 2006-2014 International Cable Protection Committee Ltd
  2. 2. Protecting Cables During Operation - Best Industry Practice  ICPC Recommendation # 6 provides Best Industry Practice for Protection of Submarine Cables and covers  Dissemination of cable route information  Stakeholder Liaison & Education  Monitoring Security of Cable Routes  Legal
  3. 3. Vessel Monitoring System (VMS) • Local laws may specify the minimum size of vessel that is fitted with VMS • VMS integrates with onboard GPS and relays information to fishing authority Cable damaged by trawling gear Source: TE Subcom • Cable owners may be able to obtain information via court order if a vessel is suspected of damaging a cable
  4. 4. Monitoring Security of Cable Route _______________ Automatic Identification System (AIS)
  5. 5. AIS  Determination of cause of fault can be uncertain  AIS provides conclusive proof for faults caused by anchor  Can protect a cable against a ship dragging it’s anchor whilst at anchor  Cannot protect a cable against a ship dragging it’s anchor whilst underway but can prevent multiple failures  Warnings sent to vessel captain and owner have avoided anchor drag faults on monitored cables.
  6. 6. Air and Sea Patrols AIR PATROL  Air patrol may be cost effective in certain areas or seasons where there is high marine activity  Patrols may be flown all year or just the seasonal peaks  Potential offending vessels can be contacted via VHF or leaflets dropped indicating location of the cable SEA PATROL  Sea patrol is effective because allows direct contact  Sea patrols may again be all year or just when fishing vessels are concentrated during certain season  Always randomise patrols
  7. 7. Terrestrial Patrols  Submerged plant actions need to be complemented with effective monitoring of the land route  Patrols ideally undertaken daily  A cable owners representative should be present during any authorised work in vicinity of the cable with authority to stop work  “Dial-before-you dig” service should be established with local authorities
  8. 8. National Legislation  National legislation could help reduce the risk of cable damage  Australian Government has recognised the strategic importance of submarine cables  Protection zones designated for Southern Cross, Australia-Japan SEA-ME-WE 3 cable systems  High risk operations banned & low risk activities restricted  Criminal penalties up to $A330,000 &/or 10 years prison Source: Australian Communications & Media Authority
  9. 9.
