Floating production oil storage device with dry ballast piping system

Abstract

The invention relates to a floating type production oil storage device with a dry type ballast piping system. The floating type production oil storage device comprises a ship body, the ship body comprises a larboard side, a starboard side, a double-layer bottom connected with the bottom of the larboard side and the bottom of the starboard side and a main deck connected with the top of the larboard side and the top of the starboard side; a process deck is arranged on the main deck; A cabin is formed among the larboard side, the starboard side, the double-layer bottom and the main deck, the larboard side, the starboard side and the double-layer bottom are each of a double-layer shell structure, the two sides of the double-layer bottom communicate with the larboard side and the starboard side correspondingly to form a ballast tank, and the double-layer bottom is provided with a ballast pipe tunnel in the length direction of a ship body; and the ballast tank is divided into a larboard ballast tank body and a starboard ballast tank body by the ballast pipe tunnel. When the floating production oil storage device is overhauled, the interior of the ballast tank does not need to be emptied, and a maintainer only needs to enter the ballast pipe tunnel for overhauling, so that the complexity of overhauling operation is reduced, and walking of the maintainer is facilitated.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a floating production oil storage device equipped with a dry ballast piping system. Background technique [0002] The floating production and storage unit is an offshore oil and gas production system device moored at sea by single-point mooring or multi-point mooring, equipped with oil, gas and water treatment devices, living and power facilities, oil storage tanks and external transportation systems. It is the most common oil storage device at sea. [0003] The traditional double-bottom and double-side offshore floating production and storage devices are all 150,000-ton load capacity, which requires a large investment, and there is a certain waste of resources when used in oil fields with small production capacity, while the traditional 100,000-ton offshore floating production The production oil storage device has a single bottom, so there is a greater risk of oil le...

AI Technical Summary

Problems solved by technology

The traditional FPSO production device is usually arranged in the central anchor windlass at the bow, so that the longitudinal bulkhead of the hull is forced to disconnect at the bow, which is unfavorable to the hull structure

Traditional floating production and oil storage production units are usually equipped with two diesel fire pumps at the head, and the risk of fire protection if the equipment fails at the same time is relatively high
