Introduction

Offshore operations have high technical content, high construction risks, high operating costs, complex operating procedures, and are affected by geological, meteorological and marine environmental conditions:

Severely restrictive features: The overall goal of GB/T 43327.6 is to ensure that specified and recognized safety standards are met wherever offshore operations are carried out:

within the full or confidence level: The design and implementation of offshore operations require special attention to national regulations in the operating area, and many factors need to be considered and reasonably controlled:

elements, as well as other standards, specifications and guidelines to ensure an acceptable level of safety in offshore operations:

GB/T 43327 "Special Requirements for Marine Structures in the Oil and Gas Industry" is applicable to various types of marine structures: This series of standards is intended to Provides wide freedom in the choice of structural configurations, materials and technologies so that innovation is not hindered: Therefore, when using these international standards when doing so, it is necessary to make reasonable engineering judgment: GB/T 43327 is planned to consist of nine parts:

---Part 1: Marine hydrometeorological design and operations: The purpose is to provide for the hydrology and meteorology in the design, construction and operation of offshore structures:

General requirements for condition determination and use:

---Part 2: Seismic design regulations and guidelines: The purpose is to provide procedures and standards for defining the seismic design of marine structures:

various requirements:

---Part 3: Upper module structure: The purpose is to provide the full life cycle of the design, construction, installation and maintenance of the superstructure module structure:

recommended practices:

---Part 4: Geotechnical engineering and foundation design: The purpose is to give provisions for the geotechnical and foundation engineering of marine structures:

---Part 5: Weight Management: The purpose is to stipulate the management and control of the weight and center of gravity of offshore facilities at each stage of the life cycle:

Require:

---Part 6: Offshore operations: The purpose is to provide requirements and guidance for planning and engineering design of offshore operations:

---Part 7: Positioning systems for offshore floating structures and offshore mobile devices: The purpose is to provide information on floating structures and mobile offshore Design, analysis and evaluation of upper device positioning systems:

---Part 8: Marine Soil Survey: The purpose is to give recommendations and guidelines for marine soil surveys:

---Part 10: Marine Geophysical Survey: The purpose is to give requirements and guidelines for marine geophysical surveys:

Special requirements for offshore structures in the oil and gas industry Part 6: Offshore operations

1 Scope

This document specifies requirements and guidance for the planning and engineering design of offshore operations, including the design and analysis of components required for offshore operations:

software, systems, equipment and processes, and methods or procedures for safely performing these operations:

This document applies to offshore operations on offshore structures, including:

---Steel and concrete gravity base structures (GB S);

---Pile-based steel structure and compliant tower;

---Tension Leg Platform (TLP);

---Deep draft floating body (DDF), including deep draft column platform or deep draft caisson device (DDCV);

---Semi-submersible production platform (FPSS);

---Floating production, storage and offloading unit (FPSO);

---Other types of floating production systems (FPS);

---Mobile offshore units (MOU);

---The upper modules and components of the above structures;

---Underwater foundations and similar structures;

---Gravity anchors, anchor piles, towed embedded anchors, suction anchors or other types of anchors;

---Tendon base;

---Related mooring systems:

This document also applies to modifications to existing structures, such as the installation of new topside blocks:

This document does not apply to the following offshore operations:

a) Not exposed to the marine environment such as construction on land construction sites;

b) Drilling, process and petrochemical operations;

c) Daily routine offshore operations during the service life of the structure;

d) Drilling operations on mobile offshore drilling units;

e) Installation of subsea pipelines, risers and umbilicals;

f) Diving operations:
