[0006] 2. Although the single point mooring system equipped with internal turret and fluid joints can make the traditional ship type FPSO have a windvane effect of 360o all-round free rotation, severe yaw motion will not only affect the normal operation of many operations, but also Severe wear on the inner turret and fluid connections, requiring frequent maintenance
[0007] 3. The longitudinal scale of the traditional ship-type FPSO is relatively large, and the corresponding longitudinal bowing and sagging bending loads are large, making the floating body vulnerable to bending and fatigue damage
[0008] 4. The slender buoys and decks of traditional ship-type FPSO will increase the length and layout difficulty of connecting piping systems among many functional modules, thus potentially increasing construction and maintenance costs
However, at the same time, there are many shortcomings in its performance: the heaving motion of the floating body is large, which is easy to cause vortex-induced vibration, the deck area is small, the living and working spaces are too close, and it is not conducive to the separation of dangerous areas and non-dangerous areas, etc.

Embodiment approach

[0041] The deck is provided with a production module and a living module which are arranged independently of each other. The production module is located on one side of the deck, including a living office building and a helicopter deck located above the living office building. In the production module, the main generator module and the thermal station module with a higher safety factor are arranged near the living module, and the oil and gas treatment module and the flare tower with a lower safety factor are arranged behind the main generator and the thermal station module. To the side of the living area, and for the convenience of fire protection, a water treatment module is installed near the flare tower, which can provide a large amount of fire water.

[0042] Similarly, the interior of the lower structure has a central cabin II at the same height as the central cabin II, and a plurality of watertight cabins surrounding the central cabin are arranged around the central cabin...

Abstract

The invention discloses a butt joint circular table type floating production oil storage system. According to the oil storage system, a floating body is provided with an upper part structural body which is in a circular table shape and a lower part structural body which is in a circular table shape; in a combined state, the bottom surface, which has a small area, of the upper part structural body is fixedly connected with the bottom surface, which has a small area, of the lower part structural body to form a connecting surface serving as a fully-loaded waterline plane of a floating type structure; and on the basis of the combined state, functional modules for mooring positioning, oil and gas production, storage, outward conveying and the like are arranged to form the novel floating production oil storage system. The floating body has the characteristic of being similar to the appearance of a sandy clock, and can overcome the defects of aspects of seakeeping capacity, strength fatigue, the arrangement of pipelines and the like in the conventional floating production oil storage system and expand the performance of the conventional floating production oil storage system. Therefore, the butt joint circular table type floating production oil storage system can realize the integration of multiple functions of well drilling, mining, storage, production, processing, outward conveying and the like of large-scale oil and gas in various sea areas easily, and has a good economic benefit.

Description

technical field [0001] The invention relates to patent classification B63 Ships or other water craft; Ship-related equipment B63B Ships or other water craft; Marine equipment B63B35 / 00 Ships suitable for special purposes or similar floating structures B63B35 / 44 Floating structures, water Tanks, water drilling platforms or water workshops, such as those carrying oil-water separation equipment. Background technique [0002] In the field of offshore engineering, the Floating Production Storage and Offloading system (FPSO) is an offshore oil and gas processing system that integrates oil and gas processing, oil storage and offloading, heating, power generation, control, and living functions. With its strong oil storage capacity and wide applicability, it has gradually become the mainstream way of developing offshore oil fields in the world. [0003] Usually, the FPSO system mainly includes various modules such as floating main body, mooring positioning, oil storage and export, o...
