Description

Technical Field

[0001] The present invention relates to a wind power equipment ship type, in particular to a wind power equipment transportation and installation integrated ship type and arrangement, belonging to the technical field of ships and marine engineering. Background Art

[0002] The existing offshore wind power resource development model requires multiple ship types to work together, including wind power installation ships, deck transport ships, crane ships, submarine cable ships, etc. The work coordination between various ship types is very likely to have a short board effect, affecting the entire project construction cycle, especially for offshore wind power installation operations with a short operation window period. The construction is extremely difficult. In addition, due to the exhaustion of offshore resources, a large number of offshore wind turbines in the offshore area are facing the need for recycling, but there is still no suitable ship type to complete the installation and recycling of offshore wind power equipment.

[0003] Introducing customized ship types for different technical requirements of offshore wind power transportation and installation is very important for reducing costs and increasing efficiency, saving energy and reducing emissions, and optimizing offshore operation processes. For offshore resources, the most important technical requirement is integrated operation and the role of ship type optimization in promoting energy conservation and emission reduction. For offshore resources, the most important technical requirement is the transportation of batch equipment. Therefore, in response to this type of technical demand, it is particularly critical to launch a series of customized ship types that integrate offshore wind power transportation and installation.

[0004] In summary, the main problems with the existing ship types in the wind power and offshore wind power industry are the prominent short-board effect of the coordination of multiple ship types, the short operation window period, the low overall construction efficiency, and the lack of customized ship types to solve the current extensive development and gray development concept of offshore wind power installation and transportation equipment. It is not conducive to the development of the industry in the direction of high added value, and it conflicts with the future green development concept. The impact on the environment and ecology is long-term and difficult to recover. In addition, due to the long shipbuilding cycle and high design and production costs of existing ship types, they are severely affected by the bottleneck of industry development and the economic cycle. How to adapt to the uncertain industry development bottleneck in the future and hedge the impact of the economic cycle on the ship industry is also a technical defect that is difficult to break through in the current ship type design.
