CURRENT STATE OF THE ART IN LARGE DIAMETER PIPELAYING IN DEEP WATER

Methods and equipment for laying and maintaining all but the deepest lines are now available and constantly undergoing improvement to meet the ever-increasing challenge of working in deeper waters and more severe weather conditons. Submarine lines are being constructed in water to depths beyond 300 ft. The immediate challenge lies in rough waters 500-600 ft deep, the next goal being in the depth range of 2000 ft. The immediate challenge is being met by the development of new techniques (both analytically and through experience) and through the design and construction of extended-capability equipment for laying, burying, welding, underwater jointing, inspection, and navigation. The development of more sophisticated equipment, such as dynamically positioned and column-stabilized barges for very deep and/or rough water, is continuing.
