Offshore wind turbine foundation floating ice towing equipment and method

Abstract

The invention discloses offshore wind turbine foundation floating ice towing equipment and method. The offshore wind turbine foundation floating ice towing equipment comprises a bearing system, a freezing system and a heating system. All parts can be prefabricated and formed, the structure is simple, the assembling process is high, and construction operation is facilitated; The equipment can be directly installed on a foundation for towing operation; floating transportation towing of various large-size and large-tonnage foundations can be flexibly adapted by adjusting the number of frame unitsand the sizes of connecting frames and partition plates; special ships or barges do not need to be additionally customized; all the parts can be repeatedly used, so that relatively good economical efficiency is achieved; the buoyancy center height of the whole system can be controlled by controlling the installation height of the connecting frames on the peripheral side of the foundation, so thatit is guaranteed that the foundation has relatively good buoyancy stability; seawater around the foundation can be directly frozen into ice, so that enough buoyancy is provided for the foundation toperform the towing operation; and after floating transportation is in place, foundation sinking is achieved by melting the ice around the foundation. A water source required in the whole process can be directly obtained locally, so that the method is convenient and quick and is an environment-friendly operation method.

Description

technical field [0001] The invention belongs to the field of offshore wind power equipment, and in particular relates to an offshore wind turbine foundation ice floe towing equipment and a towing method. Background technique [0002] With the development of the global economy and the depletion of chemical energy, people's demand for clean energy is increasing day by day. Offshore wind power, as a brand-new clean energy, has good economic and environmental benefits, does not occupy land land resources, has short infrastructure construction time, large installed capacity, and little interference to human activities. It has become a research hotspot in the development of global wind power. , is an important direction for the development of global renewable energy. [0003] At this stage, the commonly used foundation forms for offshore wind turbines mainly include gravity foundations, pile foundations, and barrel foundations that have developed rapidly in recent years. The gra...

Problems solved by technology

However, due to the problems of large structural size and high tonnage in these two types of foundation forms, it is difficult to transport the foundation

At present, there are mainly two commonly used transportation methods, one is the method of shipping, but the hoisting construction is difficult, high risk, and poor economic benefit; the other is the method of towing, but most of them require Customized special consignment platform, high engineering cost
