Single point mooring transferring buoy and multi-column type floating body thereof

Abstract

The invention discloses a single point mooring transferring buoy and a multi-column type floating body thereof. The multi-column type floating body comprises a center cylinder, top plates and bottom plates. The center cylinder is located at the center of a plurality of peripheral cylinders, and the center cylinder and the peripheral cylinder are connected with each circumferential cylinder through vertical toggle plates arranged in the radial direction. Second through holes matched with the center cylinder are formed at the centers of the bottom plates. The bottom plates are connected with the lower end faces of the center cylinder, vertical narrow plates and the peripheral cylinders in a sealed mode. The peripheral edge of the structure formed by the vertical narrow plates and the peripheral cylinders is matched with the peripheral edges of the bottom plates. The multi-column type floating body is composed of a plurality of steel cylinders and has the characteristics that the manufacturing automation degree is high, cost is low, flexibility is good, self-support capacity is good, and the demand of a stiffener is low; the construction process is simplified, the working amount of steel plate cutting and welding is saved, the construction period and construction cost of the whole single point buoy can be significantly reduced, and an obvious cost advantage is achieved.

Description

technical field [0001] The invention relates to the technical field of offshore floating production, storage and transportation systems and supporting equipment, in particular to a single-point mooring transfer buoy and its multi-column buoy. Background technique [0002] Anchorages for large tankers require deeper drafts. Due to the long construction period and high cost of building or upgrading wharves, for areas with large tanker loading and unloading requirements but no wharves or wharves with shallow water depth, single-point mooring water transfer buoys (hereinafter referred to as single Point buoys) are a popular solution. [0003] Single-point buoys generally consist of a rotating part and a stationary part. The rotating part can rotate with the oil tanker as the direction of the wind, wave and current changes. The stationary part is connected with the underwater oil delivery hose and the mooring system of the single-point buoy itself. The structure and pipeline of...

Problems solved by technology

However, due to the small size of the single-point buoy, the traditional design has the following disadvantages: the internal structure is complicated due to the large number of stiffeners arranged; the space is tight when welding the stiffeners of bulkheads and outer plates; and due to the need for a large number of angle steels Such profiles, steel cutting and welding workload is heavy; the whole construction process is heavy workload, high cost and long construction period
