Description

Technical Field

[0001] The utility model belongs to the technical field of boarding ladders, in particular to a portable boarding ladder for LNG terminals. Background Art

[0002] The fixed boarding ladder at the LNG terminal is an important device for the safe and convenient boarding and disembarking of personnel and goods between liquefied natural gas ships and the terminal. This kind of boarding ladder is usually installed at the front of the terminal and is the only passage for personnel to board and disembark during the berthing of LNG ships. In addition to personnel passage, the fixed boarding ladder can also be used for the loading and unloading of small goods or equipment. Especially when rapid or frequent cargo transfer is required, the boarding ladder will be used more frequently.

[0003] When the fixed boarding ladder fails and cannot be used safely, it will cause the port unit and necessary operating personnel to be unable to board and leave the ship for a short time, affecting the normal operation time of LNG ships, and there is a risk of delaying the ship's departure and compensating for the ship demurrage fee.
