beyond anything www.kiswire.com Pipe Lay Barges manufacture oil and gas pipes, which are laid on the bottom of the sea. For several reasons, the manufactured pipe has to be disconnected from the barge, and laid down on the seabed for a certain time(abandon) once in a while. Eventually, the same pipe needs to be taken up from the seabed and lifted onboard again to continue the manufacturing process (recovery). Both S-lay and J-lay barges operate with A&R systems as described. Depending on water depth and subsequently the length of A&R ropes required, a choice of rope is made out of the following available rope constructions.. 6x36WS+IWRC in single or dual use. Dual use of A&R ropes consist of a right and a left laid rope, operating as a pair. In the event of greater working depths, multi strand, low rotating ropes are applied. For instance, 35xK7, 35xK19S, 35xK26WS, 55xK7, 55xK19S, 55xK26WS, 55xK31WS. Torque All wire ropes have inherent rotation characteristics that will produce a turning moment in the rope. With both ends fixed and unable to rotate, the turning moment will generate a TORQUE at the fixed points. Whereas, if one end of the rope is free to rotate, the generated force will result in rope TURN and therefore load rotation. Single layer ropes, such as 6 and 8 strand constructions, have a much greater tendency to rotate under load than multi strand ropes. In fact, a multi strand rope is designed and manufactured to not to rotate at all, or minimal. The longer the ropes, the deeper the operation depths, the higher the tendency to rotate.
