Cable Lay Software
When laying cable, whether it be fibre optic or power cable, it is important to know what the cable is doing AFTER it has left the vessel. Any survey software will allow you to position the stern roller/cable chute, but the relationship between that position and where the cable ends up on the seabed is not so simple...
To model the cable physics between the departure point on the surface, and the final resting place on the seabed there are several influences which must be taken into consideration, such as;
• Cable Tension
• Cable Weight
• Cable Stiffness
• Departure Angle
• Water Depth
• Vessel Speed
• Currents
Many people have previously believed that the cable, especially heavy power cable, will land almost directly below the departure point. An assumption which some have discovered to their cost is not accurate. Likewise some people believe that lightweight fibre optic cable will land in a straight line from the stern of the vessel, in 1500m of water depth. Again this is not the case.
