ABSTRACT:
An access rope for an offshore production platform comprises an upper end attached to a chain fixed to the platform, a central stabilizing section providing a series of weights and a lower section providing hand holding implements. The weights are of different size and act so the rope swings less in response to the wind than conventional ropes. The hand holding implements include a loop in the rope which can be grasped by a user and a series of enlarged knots. The hand holding section of the main rope is helically wrapped with a smaller rope in which the adjacent wraps are spaced well apart.
