ABSTRACT:
A system is disclosed for safely transferring personnel to and from a sea launch from and to a tanker, a freighter, a bulk carrier, passenger ship or any other vessel or platform relatively larger than the launch or a boat. The system comprises a carrier, which is lifted and lowered by a winch including a hoisting motor, a continuously running tensioning motor, at least one cable connected to said carrier and operatively connected to the tensioning motor and the hoisting motor, and a coupling device disposed between the hoisting motor and the tensioning motor. A weight, which is part of the carrier, or which is suspended underneath, or, alternately, a line attached to the launch and carrier, provides the necessary compensation to the changing personnel weight and allows the carrier to follow motion of the moving deck of the launch.
