Problems solved by technology

However, the offshore assembly period is relatively long, and there are many uncontrollable factors. If encountering severe weather and environmental conditions, the construction period will be longer and the difficulty will increase, which will result in a substantial increase in cost; 2. For wind farms where the construction site is relatively close to the land In this situation, the whole wind turbine unit is hoisted and transported by a double pole transport ship, and the wind turbine unit is not fixed on the deck. Due to the short transportation distance, the interference factors of wind, waves and ocean currents have little influence

specific Embodiment

[0019] 1. Set up the following monitoring instruments

[0020] 1-2 anemometers, 1 set of fixed-point wave height meter and acquisition system, 1 set of gyroscope and acquisition system, 1-2 acceleration sensors, 36-channel data acquisition and processing system, several strain gauges, DH3817 static and dynamic Strain test analyzer; 3 laptop computers, 1 desktop computer, wires, acetone, 502 glue and sandpaper.

[0021] 2. On the entire route (for example: 120 nautical miles, but not limited to this) from the departure terminal to the wind turbine unit as a whole 1 between the platforms installed on the sea, select every distance (for example: 20 nautical miles, but not limited to this) Set a water surface measurement point, throw a SZF1-2 buoy-type wave altimeter at each measurement point along the entire route, and set an AVM-03 anemometer. The wave height meter measures the wave height at intervals (for example: 15 minutes, but not limited to this), records the wave height data ...

Abstract

The invention relates to a method for integrally and safely conveying a wind turbine on the sea which includes the following steps: 1) the wind turbine comprising a tower drum and an internal electricdevice is assembled into an integral body; 2) the wind turbine is hoisted on a deck by a hoisting ship and the bottom part of the wind turbine is welded and fixed on the deck; 3) a measuring ship isadopted to monitor the wave height, the wind speed and the wind direction; 4) a gyroscope moving instrument is fixed and a rolling angle, a pitching angle, the acceleration of the rolling angle and the acceleration of the pitching angle are measured; 5) an acceleration sensor is arranged and the transverse acceleration and the longitudinal acceleration of the upper part of the tower drum are measured; 6) strain foils are arranged at the circumference direction at the centralized location of the strain and the load data at the locations of each strain foil is obtained by a conventional electrometric method; 7) the data information obtained from step 3) to step 6) are integrated and control is carried out on the sail or sail suspending, course and sail speed of a transport barge; 8) the windturbine is wholly cut from the deck and wholly hoisted on a foundation pre-manufactured on a marine mounting part. The method has very important practical meanings on the development and constructionfor a large scale marine wind farm.

Description

Technical field [0001] The present invention relates to a method for safe transportation at sea, in particular to a method for overall safe transportation of wind turbines at sea. Background technique [0002] Wind energy occupies a leading position in the development of renewable energy. 13 countries around the world have installed capacity of more than 1 million kilowatts. Offshore wind energy has unique advantages such as not occupying land resources, keeping away from people, and causing little interference to social life. With the continuous maturity of technology, offshore wind energy will become an important part of the future green energy, but my country’s current wind power industry is still in its infancy, and offshore wind power is still blank. There are many technical and engineering links in the overall transportation and installation of offshore wind turbines. Among them, the overall offshore transportation and hoisting of wind turbines is one of the important link...
