Problems solved by technology

However, in adopting the above-mentioned structural method, there is a problem in the docking between the FPSO transporting oil and gas and the shuttle tanker, because the conventional offshore FPSO generally adopts a single-point mooring method, and the shuttle tanker is in series or alongside the FPSO system. The mooring is integrated and floats around one point together with the FPSO; however, when the multi-point mooring FPSO designed by the applicant is adopted, whether the shuttle tanker adopts tandem or side-by-side will affect the multi-point mooring system of the FPSO

Embodiment Construction

[0019] The method and device of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] like figure 1 , figure 2 As shown, the present invention includes a floating production storage device 2 (FPSO2) that is moored to the seabed at multiple points and floats on the sea surface through a mooring chain 1, in the direction of the FPSO2 that is least affected by the marine environment, avoiding the FPSO2 The mooring chain 1 is provided with at least one buoy 3 , and the bottom of the buoy 3 is anchored to the seabed through a mooring chain 4 and an anchoring device 5 . The anchoring device 5 may be a suction anchor or a pile anchor or the like. Earrings 6 are provided on the buoy 3, and mooring lines 7 are fastened to the earrings 6, and the mooring lines 7 usually float on the sea surface. A mooring line 9 connected to the shuttle tanker 8 is provided on the deck opposite the FPSO 2 and the buoy 3 . The mo...

Abstract

A flexible connecting and anchoring method and its apparatus for delivering petroleum between oil tanker and floating petroleum recovering and storing platform are disclosed. At least one set of flexible connection apparatus anchored to seabed is arranged on sea surface. The cable at the stern of an oil tanker is tied to the float bowl of said flexible connection apparatus and the cable at its bow is tied with the cable of said floating platform. A flexible petroleum delivering pipe is connected between oil tanker and floating platform.

Description

technical field [0001] The present invention relates to a method and device for offshore oil transportation and mooring, in particular to a method and device for flexible connection and mooring of offshore oil transportation aiming at a multi-point mooring floating production oil storage device. Background technique [0002] At present, with the substantial increase in the consumption of oil and gas resources in my country, the country's demand for oil and gas resources is also increasing, and it is urgent to develop my country's offshore oil and gas resources effectively, economically and quickly. At present, in the development of my country's offshore oil, in addition to continuing to develop large and medium-sized oil and gas fields, the development of offshore oil fields, such as Bohai Bay and Weizhou Bay in the South China Sea, is also actively carried out. However, if these oil fields continue to follow the model of large and medium-sized oil and gas fields Development ...
