Problems solved by technology

This flow-making method can meet the requirements to a certain extent, but the problem is that when it is necessary to simulate the high surface flow velocity, the power of the flow-making pump on the surface alone can meet the requirements, and the flow-making pumps on the other layers cannot play a role , the high flow rate on the surface is limited, and whe...

Abstract

The invention relates to a parallel flow deepwater current system and relative method used in ship and sea project. The invention comprises: six layers of current devices, while each one is formed by driving water pump, a inlet tube and a outlet tube, while the inlet and outlet tubes connect two ends of water pool; six layers are vertically arranged around the water pool. The method comprises: arranging connecting channels at the top two layers and the bottom two layers; via adjusting the valve of tube, the energy of driving pump that driving water is distributed between the vertical layers to produce variable section currents. The invention can simulate variable deepwater sections demanded by tests and reduce cost and save energy. And since the upper and lower layers are connected, the water pool can generate ascending and descending currents.

Description

technical field [0001] The invention relates to equipment and methods in the field of ships and ocean engineering, in particular to a co-current deep-water flow-making system and method. Background technique [0002] With the continuous increase of world energy consumption and the gradual saturation of onshore and shallow sea oil and gas development, people have expanded the field of oil and gas development to the deep sea. Although the development of science and technology and the advancement of marine engineering have made human beings make continuous progress in the development of deep-sea marine engineering, the various complex marine environments in the deep sea still bring great difficulties to the production and survival of marine engineering structures, especially deep-water currents. Different flow velocities at different depths are one of the main difficulties in the design and construction of deep-sea marine engineering structures. For this reason, it is necessar...
