ABSTRACT:
A method for transferring fluids and personnel between a work vessel and an offshore marine platform includes the placement of an elongated self-supporting frame between the work vessel and the marine platform. A walkway is provided on the frame. Pipe racks are provided on the frame, one pipe rack on each side of the frame so that a pair of pipe racks are on opposing sides of the frame. Hand rails are mounted in between the walkway and each pipe rack. A fluid holding pan extends under the walkway and the flowlines. In this fashion, fluid that falls from either a pipe rack or a walkway to the pan can travel through a common drain or collection area.
