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

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 owners may be able to
obtain information via court order if
a vessel is suspected of damaging
a cable

Monitoring Security of
Cable Route _______________
Automatic Identification System
(AIS)
www.iscpc.org
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.

Air and Sea PatrolsAIR 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
www.iscpc.org
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
www.iscpc.org
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
