Description

A series of vessels integrating wind power equipment transportation and installation, and their layout Technical Field

[0001] This invention relates to a wind power equipment vessel type, and more particularly to an integrated wind power equipment transportation and installation vessel type and layout, belonging to the technical field of shipbuilding and marine engineering. Background Technology

[0002] Existing offshore wind power development models require the coordinated operation of multiple vessel types, including wind turbine installation vessels, deck transport vessels, crane vessels, and cable carriers. The coordination between these vessel types is highly susceptible to bottlenecks, impacting the entire project construction cycle. This is particularly true for offshore wind turbine installation operations with short operational windows, where construction becomes extremely difficult. Furthermore, due to the depletion of near-shore resources, a large number of offshore wind turbines in these areas require recycling, but currently, there is still no suitable vessel type capable of handling the installation and recycling of offshore wind power equipment.

[0003] To address the diverse technical requirements of offshore wind power transportation and installation, customized vessel designs are crucial for cost reduction, efficiency improvement, energy conservation, emission reduction, and optimized offshore operation processes. For near-shore resources, the most important technical requirement is integrated operations and the energy-saving and emission-reduction benefits of vessel optimization. For offshore resources, the most important technical requirement is the transportation of equipment in bulk. Therefore, developing a series of customized vessels integrating offshore wind power transportation and installation is particularly critical for these latter needs.

[0004] In summary, the main problems with existing vessel types in the offshore wind power industry are: significant shortcomings in vessel coordination during multi-vessel operations; short operational windows; and low overall construction efficiency. Furthermore, the lack of customized vessel types to address the current extensive and gray-market development approach for offshore wind power installation and transportation equipment hinders the industry's development towards high value-added sectors and conflicts with future green development principles, resulting in long-term and difficult-to-recover environmental and ecological impacts. Additionally, existing vessel types suffer from long shipbuilding cycles, high design and production costs, and are severely affected by industry development bottlenecks and economic cycles. Adapting to future uncertainties in industry development and mitigating the impact of economic cycles on the shipbuilding industry are also technical shortcomings that are currently difficult to overcome in vessel design.
