Multifunctional installation and investigation vessel

Abstract

The invention relates to a multifunctional installation and investigation vessel, which comprises a vessel body and is characterized in that an A-type lifting frame, an oceanographic engineering crane and a derrick are sequentially arranged in the X direction on a main deck of the vessel body; a crane winch is arranged below the main deck, and a steel wire rope passes through the main deck; the crane and the crane winch are respectively arranged in positions on two sides of the vessel body; multiple empty tanks are arranged between the inner bottom and the outer bottom of the vessel body and in positions on two sides of the vessel body, and multiple lower water ballast tanks are arranged on the inner sides of the two sides of the vessel body; opposite tanks on the two sides of the vessel body are communicated via communication passages; an energy converter tank is also arranged at the bottom of the vessel body. When the tanks are damaged, water can enter the empty tanks uniformly, so that the stability is improved; when water in the empty tanks on one side of the vessel body is excessive, water can flow from one side to the other side of the vessel body via the communication passages, so that the transverse inclination after damage of the vessel can be reduced and the damaged stability is improved.

Description

technical field [0001] The invention relates to a marine geological survey ship, in particular to a multifunctional installation and survey ship. Background technique [0002] Energy is an indispensable element of today's world economy, while terrestrial energy is gradually being exhausted under continuous consumption. According to surveys and estimates, 28% of the world's oil and 37% of natural gas are stored in the seabed, and there is still enough for human consumption in this century. Combustible ice and other metal minerals. However, from the initial exploration to the final recovery of oil wells, the development of subsea oilfields needs to go through the processes of exploration, discovery, reservoir division, equipment installation, primary production, and re-exploitation. Among them, marine engineering geography and geological survey are one of the important tasks in the development and development of subsea oil wells. The purpose is to confirm potential man-made d...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: the existing marine geological exploration ships, geophysical exploration ships, and lifting ships all have a single function. It is also necessary to install large-scale marine structural parts. At this time, multi-vessel cooperation is often required, resulting in high operating costs and low input-output ratios.
