FPSO (Floating Production Storage and Offloading) recycling assessment system and method

Abstract

The invention discloses an FPSO (Floating Production Storage and Offloading) recycling assessment system, which comprises an input module, a preliminary design module, a risk assessment module, a technical assessment module and a decision module, wherein the input module is used for collecting the data of a new oil field and the design data of the FPSO in the initial operating oil file of the FPSO; the preliminary design module is used for carrying out superstructure preliminary design according to data input by the input module, ship body scale checking, mooring design, superstructure arrangement and an equipment specification; the risk assessment module is used for identifying risks and a seminar and cost assessment result according to a dangerous source distinguishing method; the technical assessment module is used for checking an existing ship situation and assessing and integrating new mooring and superstructure design to carry out lifetime extension assessment; and the decision module is used for concluding initial research, preliminary design, risk assessment and technical assessment results. By use of the system, a situation that a focus of attention is centralized to a problem irrelevant to recycling assessment due to information loss or human factors can be avoided, the criticality of each problem is sorted, the focus of attention is centralized to the key point of the problem, and a decision process is rationalized.

Description

technical field [0001] The invention relates to the field of oilfield operation safety, in particular to an FPSO reuse evaluation system and method. Background technique [0002] FPSO (Floating Production Storage and Offloading) is one of the main modes of offshore oil development, and is widely used in crude oil production, storage and export in various sea areas of the world. Among them, the structural status of the FPSO floating body is an important link related to the normal operation of the entire FPSO. Once the structural status of the FPSO floating body is damaged, the safety of the entire FPSO will be greatly threatened. economic losses, and there is a risk of oil spills, which may lead to ecological disasters. [0003] FPSO reuse evaluation decision-making is currently to conduct technical evaluation on FPSO reuse through the technical evaluation method of conventional marine engineering structures, and then hold an expert seminar to review the technical evaluation...

AI Technical Summary

Problems solved by technology

The main problem at present is that there is no overall integration framework, mainly manifested in: no integrated technology assessment in the overall risk assessment process; risk assessment is difficult to integrate into the decision-making process

As a result, existing FPSO reuse assessments and decision-making are not sufficiently linked

[0005] Furthermore, in the decision-making process, certain risks will be increased due to information loss, or if too much attention is paid to a certain point in the decision-making process, other important issues will be ignored.

The loose connection between evaluation and decision-making will inevitably lead to more subjective tendencies in decision-making, and lack of global vision for FPSO reuse

In addition, this potential information loss and subjectivity in the decision-making process may lead to: lack of reliable FPSO reuse technology assessment, resulting in increased technical risk; lack of a global view of FPSO reuse projects, thereby increasing management and economic risks
