Abstract
An arrangement that brings all of the separate elements of equipment used to lay product offshore such as pipe, umbilicals, and power cables and assembles them into a single device that can be installed on a vessel of opportunity, and includes functional improvements of each. A base is used for mounting, integration, and installation of the separate elements onto a vessel. The base receives a movable lay chute, means for moving and stabilizing the lay chute, a movable hang off clamp and work table, a movable access platform, a product support arm and wheel, and a fixed chute.
