Abstract

A modular seismic cable handling system contained in a knockdown intermodal freight container, the freight container configured for secure containment and shipment of the system, as well as being configured to open to a platform designed to engage the main deck of a marine vessel, providing, with cable handling equipment contained therein, a relatively portable, self contained seismic cable handling system, on a vessel which may not specifically be designed for such an activity. The present invention may include a large wheel mounted in the front of the vessel for retrieving seismic cable from the water, a horizontally mounted cable handler comprising an eight wheel cable puller for pulling the cable from the wheel, urging same to the main deck level of the vessel, the cable puller comprising four pairs of tires configured for frictional, rotational contact another along their outer surface, to frictionally grab and pull a seismic cable along a linear path. The pulled cable is urged along a track running generally the length of the vessel, where a smaller, rear cable puller further urges the cable to the rear of the vessel. The present system further contemplates a trolley cable deployment system for deploying the cable into cable bins on the main deck for storage, as well as to sea, which trolley system includes a cable wheel puller arrangement having movement situated along the longitudinal axis of the container, allowing flexible placement of the cable in cable storage bins situated on the main deck area.
