The importance of high-altitude operation anti fall devices for scientific research vessel maintenance personnel

Scientific research ships are not ordinary vessels. They also undertake observation tasks and assist scientific researchers in obtaining first-hand information. Some scientific research ships can also obtain data from the distance from the upper atmosphere to the sea surface, and even from a distance of several kilometers from the water surface to the seabed.

The deployment and recycling system is a "ferryman" on deep-sea research vessels. It, together with systems such as hoisting, towing, hydraulic, and electrical control, forms a distribution and recovery system. With the support of the A-frame, the hydraulic station provides power to drive the variable amplitude oil cylinder to swing the A-frame at different operating angles, in order to achieve the deployment and recovery of deep-sea base stations.

When the A-frame malfunctions, the equipment is floating on the water surface and can be quickly repaired and retrieved from the submersible. However, if the equipment is suspended in mid air and cannot be retrieved or released, it is very dangerous. Therefore, a comprehensive and systematic inspection must be conducted before each voyage departs. However, there may also be some unexpected situations during sea trials. During scientific expeditions, there was a situation where the hydraulic main oil pipe at the top of the A-frame leaked oil. After emergency recovery of the manned submersible, the scientific researchers quickly climbed to a height of 15 meters that fluctuated up and down with the waves to replace the oil pipe. The entire process required time and effort, greatly testing the researchers' ability to adapt.

The danger of working at a height of 15 meters on the sea surface is self-evident. Once there is a high-altitude fall, it is no longer just a matter of injury. In the vast sea, turbulent water currents, and various fierce fish lurking in the water, scientific researchers will wear high-altitude work fall arresters when working in the high space of ships to ensure their own safety.
