Twenty years ago, one-meter burial was common. As indus- trial ? sheries continue to extend their activities into deeper water, the requirements for greater cable protection at deeper depths continue to evolve as well. These trends have led to two-and three-meter burial, resulting in higher sea plow tow tensions becoming more common, particularly on high-capac- ity transoceanic systems.
