Description

Technical Field

[0001] This invention relates to a method for launching and recovering marine submersibles, belonging to the technical field of ships and marine engineering. Background Technology

[0002] Based on existing wave distribution data, sea states of force 6 or higher are highly probable. However, current ocean submersible transport vessels typically use a hoisting method to deploy the submersibles onto the deck or into the operating area. This method is easily affected by sea conditions, resulting in low deployment and retrieval efficiency and a high risk of collisions between the submersible and the vessel, leading to damage. Alternatively, transport vessels can use a semi-submersible design, deploying and retrieving the submersible through buoyancy adjustments. This semi-submersible method requires precise control over ballast water levels, resulting in a bulky hull and numerous pumps, significantly increasing production and operating costs. Furthermore, both of these methods only allow the submersible to be retrieved onto the deck, and its anchoring and movement are heavily influenced by the marine environment. For these reasons, existing ocean submersible transport vessels struggle to operate in sea states of force 6 or higher, resulting in short operational windows and difficulties in safely and efficiently deploying and retrieving submersibles. Summary of the Invention
