A marine engineering positioning device

Abstract

The invention relates to the field of marine resource utilization engineering, in particular to a positioning device for marine engineering. The specific technical solution is: including a fixed heave plate, a floating body and a cylinder, the fixed heave plate and the floating body are both arranged on the cylinder, a moving heave plate is also arranged above the fixed heave plate, and the moving heave plate The swing plate is connected to the column through a connecting frame, and the connecting frame can adjust the distance between the moving heave plate and the fixed heave plate. Compared with the prior art, the present invention is an ocean engineering positioning device with stable positioning, strong applicability, low failure rate and effective avoidance of resonance.

Description

technical field [0001] The invention relates to the field of marine resource utilization engineering, in particular to a positioning device for marine engineering. Background technique [0002] The ocean is a huge treasure house of resources, with a large number of fish resources, oil and gas resources, and the ocean accounts for 71% of the total area of ​​the world with a lot of room for development and utilization. As one of the foundations for the establishment of urban agglomerations on the sea, offshore platforms have also become a resource utilization of marine space. focus of attention. [0003] At present, most domestic offshore platforms are self-elevating platforms, which adopt a self-elevating design and use a set of huge and complex mechanisms to drive the offshore platform to actively move up and down to adapt to changes in sea level. The structure itself is complex and the cost is extremely expensive. , the cost of using it to construct an offshore urban agglo...

Problems solved by technology

[0003] At present, most domestic offshore platforms are self-elevating platforms, which adopt a self-elevating design and use a set of huge and complex mechanisms to drive the offshore platform to actively move up and down to adapt to changes in sea level. The structure itself is complex and the cost is extremely expensive. , the cost of using it to build an urban agglomeration on the sea is too high, and the jack-up platform is suitable for shallow waters, generally the water depth does not exceed 300-400 feet (90-120 meters)

The cost of the semi-submersible platform is relatively lower than that of the jack-up platform, because it floats on the sea surface and is applicable to a wide range of water depths; however, the semi-submersible platform is relatively affected by natural wind and waves, and the platform shakes greatly in bad weather, which not only makes the platform It is easy to cause damage to personnel and platform equipment, and it also makes it impossible to apply engineering operations that require a stable environment such as dry tree collection systems
