A swing test device for offshore high-rise towers

Abstract

The invention discloses a sway test device for a towering tower at sea, aiming to provide a safe and reliable sway test device whose motion simulation is more practical. Including tower, tower reinforcement mechanism and tower motion simulation mechanism. The tower strengthening mechanism includes a steel structure frame composed of multiple beams and columns passing through connectors, at least one circular tower hoop, and multiple dampers connecting the tower hoop and the beams in the same plane. The tower simulation motion mechanism includes the upper platform, the simulation motion driving unit and the sliding unit, and the simulation of the offshore working conditions of the tower is realized through the motion synthesis of the simulation motion driving unit and the sliding unit. The sliding unit is set in the tower motion simulation mechanism of the test device, which can not only realize the multi-degree-of-freedom swing of the tower, but also realize the drift motion of the tower, and the simulation motion simulation is more realistic. At the same time, the rigid-flexible combination of the steel structure frame and the damper is used to fix it, making it safer and more reliable to use.

Description

technical field [0001] The invention relates to the technical field of offshore oil and natural gas exploitation, and more specifically relates to a performance research and test device for a towering reaction tower on a floating production, storage and unloading device. Background technique [0002] With the continuous advancement of energy technology, offshore oil and gas fields have been continuously developed and utilized. The floating production, storage and offloading unit is currently an offshore oil and gas field development unit that integrates natural gas pretreatment, liquefaction, storage, loading and unloading, and export. Since most of the oil and gas extracted from the seabed contain acid gases such as carbon dioxide and hydrogen sulfide, the existence of such acid gases will lead to problems such as corrosion of storage and transportation pipelines, reduction of gas calorific value, and formation of hydrates. Carry out deacidification treatment. According t...

Problems solved by technology

However, this reinforcement method is difficult to cope with towering towers with a height greater than 15 meters and an aspect ratio greater than 1. It cannot provide rigid support and lacks safety protection. At the same time, traditional motion simulation devices only provide two degrees of freedom or six degrees of freedom. , does not take into account the drift movement of the moored floating production storage and offloading device when encountering strong wind and waves, which cannot fully reflect the actual working conditions of the tower, so that the experimental results often cannot reflect the actual performance of the tower
