Key Differences
5
Comparison
Cables
• Array cables – 800~1200m cables lengths – Higher Volumes - 80~100 cables per year
• Export cables – 20~120km lengths (5,000 ~9,000 T cables)
Vessels
• Pushing for higher volumes and weights – specific new vessels
• Multiple tasks from same vessel – multi skilled personnel
• Vessel transfers – safety and wave height limitation
Trenching Tools
• Mechanical trenching innovations for cables ends and depth of burial
• Jetting innovations – cable burial in clays
