Description
TECHNICAL FIELD The present invention relates to the field of ocean engineering equipment, and in particular, to an offshore overall wind turbine installation ship.
BACKGROUND The installation of an offshore wind power plant is considerably complex systematic project. It mainly includes wind turbine foundation installation, pre-installation and offshore installation of the wind turbine, use and deployment of the wind power installation ship, arrangement of the cable, construction of the offshore substation and the like. The installation of the wind turbine and its foundation is conducted at sea, which has high requirement on the installation technology and is vulnerable to environmental factors such as weather, climate, waves and the like. Therefore, a special wind power plant engineering ship or a special wind turbine installation ship (platform) is required in the construction process.
The offshore wind turbine installation operation platform is core equipment for building the offshore wind power plant. The offshore wind turbine installation operation platform mainly includes a platform main body, a pile leg, a lifting device, a crane and the like. During work, the platform inserts the pile leg into the seabed through the lifting device and then lifts the main body part from the water surface to the working position, thereby providing a stable platform for wind turbine installation. After the work, the pile leg is lifted to achieve the navigation function. The ship type may be regarded as a combined body of a self-elevating platform and a transport ship, with multiple functions, complex equipment, intensive technology, high precision requirement and high manufacturing difficulty. The transportation and installation of the offshore wind turbine set is a key link in the construction of the wind power plant. The development of related equipment, for example the development of the installation operation platform (installation ship), as an important link in the wind power industry chain, has a broad and optimistic market. No matter in construction or maintenance in the operation process, the offshore wind power plant requires the offshore engineering ship to perform construction. The particularity of the wind turbine set requires a special installation operation platform. The installation operation platform needs to have a sufficiently large hull and an ample deck space to load and transport parts of the wind turbine set, with sufficient loading capacity and without a supply ship; the installation operation platform needs to be equipped with a plurality of cranes to lift and install the parts of the wind turbine set; special equipment is required to adapt to the hostile sea conditions, ensure stable operation and reduce the downtime as much as possible; construction with the same content can be conducted efficiently and repeatedly at numerous operation points, most of installation and maintenance work can be completed independently; and residence 15 provided for constructors.
The self-propelled ship with the positioning pile leg only has the wind turbine set transportation capability. Inserting the positioning pile into the seabed before installation operation can relatively fix the hull and improve the stability of the hull. The hull floats in the water by its own buoyancy, but when the wind and waves are relatively strong, the hull still can fluctuate with the waves, which still affects the installation operation.
In order to solve the influence of the wind and waves, a self-elevating (non-self- propelled) platform installation mode appears. The self-elevating (non-self-propelled) platform is an installation platform with pile legs and can be lifted by itself. The self- elevating (non-self-propelled) platform cannot be sailed by itself and cannot transport the wind turbine set. The self-elevating (non-self-propelled) platform needs to be dragged by a tugboat to the appointed work site. After the self-elevating (non-self-propelled) platform arrives at the site, the pile legs are inserted into a seabed supporting platform, and the platform is lifted out of the water surface by a hydraulic lifting device for form a stable platform which is not affected by the waves. The wind turbine is lifted by the crane on the platform. Since it cannot be sailed by itself and has low installation efficiency, a set of auxiliary ship is required.
At present, the wind turbine is installed by the crane. Since there is often strong wind at sea, the working efficiency of installation is low due to the influence of the sea wind.
