Manufacturing method of wave self-adaptive ocean platform full-automatic gangway device

1. The utility model belongs to the technical field of ocean platforms, and relates to a wave self-adaptive ocean platform automatic gangway device.

Background technique:

2. During the offshore construction of the offshore jack-up platform, the main deck of the platform hull is usually more than 10 meters away from the water surface. Each time the platform lifts the piles, it takes a long time. During the operation, the operators often need to get on and off the platform. Due to the large distance between the main deck of the platform and the water surface and the large wind and waves on the sea, it is very inconvenient for personnel to get on and off the platform. Especially in strong wind and wave weather, a simple, fast and less affected by wind and wave upper and lower platform device is needed. There are mainly two traditional methods. One is to use cranes on the platform to lift personnel. In this method, personnel must enter a special gondola. Due to the influence of wind, the gondola will swing, which not only has the risk of collision, but also People falling into the water may occur; the other is to directly transport people on and off the platform by helicopter, but this method requires a helicopter deck on the construction platform, otherwise the helicopter cannot be used to transport people, and the cost of using helicopters is high. It is less and greatly affected by wind, so it cannot be used in windy weather.

3. In recent years, the installation of gangways on the offshore platform can greatly save the time and economic cost of climbing the offshore platform. However, accidents of collisions between ships and gangways often occur during the climbing of offshore platforms, which may affect the structural stability of the offshore platforms and even cause casualties. Based on the shortcomings of the existing offshore platform gangway, it is urgent to propose a new type of gangway device and control system that can act on the ship's deck, which can adjust the height of the gangway adaptively along with the waves, and effectively avoid the collision between the gangway and the ship and the crew. Injuries, while the automatic telescopic ladder can help operators quickly get on and off the ocean platform.
