Description

OFFSHORE WIND TURBINE INSTALLATION SHIP EQUIPPED WITH SELF- EXPANDING OBLIQUE SUPPORT TYPE PILE SHOE
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 offshore wind turbine installation platform is core equipment for building the offshore wind power plant. The offshore wind turbine installation 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.
For the pile leg in the existing offshore wind turbine installation platform, it is necessary to add a pile shoe at the lower end of the pile leg generally and the pile leg is supported on the seabed surface by the pile shoe. As the saying goes, the earth trembled and the mountains swayed without a firm foundation, and the existing pile shoe is not reinforced when supporting the seabed surface, so it is not stable. How to avoid the use of hydraulic or electric driving devices in underwater operation is the problem that requires consideration and attention in the design scheme of reinforcing the pile shoe.
In addition, 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 selt-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.
