Large ocean sea channel surveying vessel

Abstract

The invention relates to a large ocean sea channel surveying vessel which carries various high-performance specialized ocean surveying equipment systems, and comprises a manned measurement boat, an unmanned measurement boat, an autonomous unmanned underwater vehicle release and recovery system, a pull-type measurement device, a navigation type multi-element measurement system, a thermohaline depth gauge detector, an underwater fixedly-mounted acoustic device and a measurement winch device. The measurement operation deck area comprises a tail operation area and a broadside operation area, and the multi-point putting and recycling requirements of measurement equipment can be met; the underwater fixedly-mounted acoustic device is mounted at the bottom of the ship in front of 1 / 3 of the length of a midship of the ship through a bow hoisting appendage; a stabilizer adopts a retractable fin stabilizer and a passive controllable anti-rolling tank, and two types of stabilizer equipment are intelligently and automatically controlled through a combined control system; the surveying vessel is further provided with a DP-2-level dynamic positioning system, and the surveying precision, continuity and reliability in the long-period gridding surveying operation and fixed-point surveying operation process in the deep sea and the far sea can be guaranteed.

Description

Technical field [0001] The present invention relates to a sea channel measuring boat, in particular to a large ocean hypertaral measuring boat for a deep-far sea survey measurement. Background technique [0002] The sea channel measurement ship is mainly used to survey the seafood and waterway, measure water deep, explore seabed, geomorphology, investigation and collection of seafront, tidal and other coast hydrological materials, installation, maintenance of navigation equipment and executive ocean investigation, etc., currently domestic and maritime system fields The sea channel measurement ship exists as follows: [0003] (1) Lack of large-scale ocean seaptome vessels for far-long seawate domains, small vessels are small, low self-suction, resistance, and poor resistance, etc., the adaptability of harsh environmental conditions such as far-reaching sea waters such as South China Sea difference. [0004] (2) There is less in the board, the measurement equipment system is simple...

AI Technical Summary

Problems solved by technology

[0003] (1) There is a lack of large-scale ocean-going hydrographic survey ships suitable for deep-sea waters. The ship is small in size, low in endurance and self-sustainability, poor in wind resistance and seakeeping performance, and has poor adaptability to harsh environmental conditions in deep-sea waters such as the South China Sea. Difference

[0004] (2) There are few survey and measurement functions on board, the configuration of the measurement equipment system is simple, the measurement range is limited, the measurement accuracy is poor, and the measurement capability is weak. At present, it is mainly used for scanning tasks in coastal and shallow offshore areas such as ports, waterways, and anchorages. , there is a lack of multifunctional and specialized measurement equipment and systems suitable for deep sea waters

[0005] (3) The automation, unmanned, and intelligent level of the measurement equipment is low, and the all-round applicability to perform measurement tasks in remote islands, reefs, shallow waters, and deep-sea harsh and extreme conditions is insufficient

[0006] (4) There is generally no dynamic positioning system or only a DP-1 dynamic positioning system, and the reliability of long-period measurement operations in deep and open seas is poor
