MICROWAVE SURVEY SYSTEM USED FOR OFFSHORE WORK

Brown & Root, Inc. recently implemented a new Microwave Survey System Utilizing a shipboard computer to control the lay barge L.E. Minor during the installation of 27 mi of 42 in. submarine pipeline offshore Iran. The system acquires and digitally processes range data from two known shore of platform locations to the lay barge and plots barge coordinate positions on a visual display. The theoretical, or desired route is also shown. The barge anchor winch operators make simple right or left corrections for any displayed error. Absolute accuracy of the plotted coordinates was verified on the job site to be plus or minus 2 meters.
