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

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:
