Problems solved by technology

Although the single-hull wind power installation ship with piled legs has a simple structure and is easy to manufacture, it greatly limits the loading capacity and working water depth of an ultra-large wind power installation ship, so it is mainly used in small and medium-sized wind power installation ships; single truss-type piled-leg wind power installation ships It adapts to the requirements of large loading capacity and deep working water depth of ultra-large wind power installation ships, but the construction process is complicated and the cost is high

Abstract

The invention discloses a design scheme of a self-elevating vessel pile leg, in particular to a design scheme of an ultra-large self-elevating wind turbine installation vessel with multi-type pile legs. The wind turbine installation vessel projects designed and built at the present stage are all provided with single-type pile legs, and the wind turbine installation vessels with the single-type pile legs has various shortcomings that the wind turbine installation vessel with single casing type pile legs is not strong in loading capacity or operating depth, and the wind turbine installation vessel with single truss type pile legs is complex in building process and high in cost. According to the ultra-large self-elevating wind turbine installation vessel with the multi-type pile legs, load distribution of the ultra-large wind turbine installation vessel is optimized, load of the wind turbine installation vessel is reasonably distributed, the design scheme that the multi-type pile legs are adopted for the ultra-large wind turbine installation vessel is provided, and the advantages of the casing type pile legs and the truss type pile legs are sufficiently combined, so that loading capacity and operating depth of the ultra-large wind turbine installation vessel are improved, and simultaneously the ultra-large wind turbine installation vessel is superior in terms of building process and cost.

Description

technical field [0001] The invention relates to the field of construction of offshore platforms and large ships, in particular to an ultra-large self-elevating wind power installation ship with multiple types of legs and a design method thereof. Background technique [0002] With the overall development of the global economy, the energy problem has become a worldwide problem, and the development and utilization of new energy substitute products have become the research direction of experts in related fields all over the world. Wind energy is a kind of abundant, widely distributed, clean and renewable energy, and it is also one of the most important energy substitutes. With the operation of land wind farms and the development of marine technology, offshore wind power generation has gradually begun to take shape, and the development situation has rapidly heated up. Especially in the past two or three years, with the continuous attention of governments of various countries, th...
