[0002] A multipurpose transport ship is a ship with multiple transport functions, used to transport various types of cargo, including but not limited to containers, bulk cargo, heavy cargo, wind power equipment, construction machinery, etc.

[0003] Based on the current development trend of "carbon peak and carbon neutrality", offshore wind power has achieved vigorous development in recent years, and the demand for submarine cables has increased simultaneously, so the demand for submarine cable transportation has also increased accordingly. Submarine cable transportation requires the configuration of dedicated cable storage equipment and cable transmission systems to ensure the safety of submarine cable transportation. However, conventional multi-purpose transport ships do not have relevant equipment and are not qualified for submarine cable transportation.

[0004] In addition, previous engineering experience usually adopts the cable-laying vessel solution, integrating the submarine cable transportation, storage, and cable-laying functions into one ship. However, this solution requires a very high one-time investment and is not transportation-oriented, resulting in low economic efficiency of submarine cable transportation. Utility Model Content
