Because they are large and medium-sized heavy equipment, they are completely dependent on large ships for deployment and operation, and cannot achieve accurate fixed-point operations. . Second, it is bulky, cumbersome, and difficult to transport; in some seabed depths where only a small amount of sampling is required, and in specific occasions where more precise fixed-point drilling is required, the existing drilling rigs are difficult to operate and operate, and the sampling depth is too high. Long and more likely to cause waste of material costs. Third, the addressing efficiency is low; due to the complex topography of the seabed, the drilling rig needs to sit on the bottom and sit firmly for sampling, and the equipment needs to be perpendicular to the seabed to start drilling. Because the equipment itself is relatively heavy, if the equipment is found to be on a slope and the angle is too large after sitting on the bottom, the equipment can only be stowed again, and then moved away from the bottom for a certain distance, and then the equipment can be dragged by moving the boat. to a suitable location.
