SY/T 4805-1992 Recommended practice for production facilities on offshore structures
Some standard content:
In order to meet the requirements of developing offshore gas resources in my country, the Ministry of Energy of the People's Republic of China has issued the 174th edition of "Recommended Practice for Production Facilities on Offshore Structures" of the American Petroleum Institute, namely API RP 2G (API Recommended Practice for Production Facilities on Offshore Structures - 1994) and Supplement 1 to API RP 2G (API Recommended Practice for Production Facilities on Offshore Structures - 1994) and Supplement 1 to API RP 2G (API Recommended Practice for Production Facilities on Offshore Structures - 1994) Edition The Standard of the People's Republic of China for the Natural Gas Industry.
If there is any objection to the translation of the standard, the original standard shall prevail. In the design, construction and use of offshore oil and gas development projects, when the laws, regulations and provisions of the government or other competent authorities of the country where the standard is located are involved, the relevant orders, regulations and provisions issued by the government of the People's Republic of China or the competent authorities shall be followed. The data or quantitative calculation methods of environmental conditions such as wind, waves, currents, ice, temperature, earthquakes, etc. in the original standard can be used as a reference if they are in line with my country's actual conditions. Otherwise, data and quantitative calculation methods that meet my country's actual environmental conditions should be used. Regarding measurement units, metric units are mainly used. That is, the English unit should be marked in brackets before and after the metric unit value. In order not to change the formulas, line shape characteristics, coefficients and coefficients in the original standard, all English units shall be used.

SY/T 4805-S2
Chapter 1. Scope
This practice collects in one document various procedures and guidelines useful in the planning, design, and layout of offshore production facilities for the safe, safe, and efficient production of natural gas and crude oil. This recommended practice is not to be construed as a technical specification, nor as a fixed guideline regardless of the accuracy of its design and definition, nor should it be used to override or in some way override any existing code or regulatory requirements.
12 Multiple Uses of Structures
The multiple functions of structures are essential to the performance of the multiple functions required for drilling and oil production. For new structures, if the various functions and requirements of the production equipment are well understood, the initial layout should be carried out in accordance with this recommended practice. In many cases, existing structures that were built before all relevant production requirements were known require that the equipment be arranged and deployed directly within the space. In this case, the layout should be as reasonable as possible under the guidance of the production work. When planning and arranging production facilities, in addition to fully considering the drilling and repair equipment, the specific operation of other drilling and repair equipment is not within the scope of this work.
13 The primary consideration
Within the strict limitations of each industrial structure, the primary consideration is safety and pollution prevention. For the escape of flammable liquids or volatiles, whether caused by normal operating conditions or by abnormal or abnormal conditions, maintenance must be provided. Equipment that may cause fire under normal or normal operating conditions should be connected to the main fuel source or other protective measures should be taken. Chapter 2 Definitions
Compressor, rotary or complex, including its transmission equipment and related equipment, refrigeration, pipelines, conditioning, control equipment, etc., used to compress natural gas or air from low pressure to high pressure: main deck structure, the uppermost deck
Lower deck/wellhead deck. The lower deck is the closest to the working deck. The lower deck is located at the lower deck/wellhead deck. It is located below the lower deck/wellhead deck. It can be named as the lower deck A, the lower deck B, etc.
Central area of the wellhead deck, the lower deck/wellhead deck or the lower deck deck, and the part within the boundary of the surrounding support. Drilling operation deck area The board area required for drilling or repair operations. Deck cantilever area The lower deck/wellhead deck: the lower deck/wellhead deck or the lower deck deck, and the part outside the boundary of the surrounding support. Direct combustion container The container where the fire directly increases the internal fluid to increase its temperature. Open flame process area The area where the open flame container is located. Fire wall is built with non-hazardous materials to prevent the spread of fire and serve as a partition wall for auxiliary bearing barriers, generator sets and other energy-generating equipment, including transmission devices and working equipment. The header is a pipe section or chamber that receives fluids from two or more branches. It is used to lift materials and products from the top vertically to the collection layer of the structure. It is usually a crane or a hoisting device installed on a slope. These lifting devices can be driven by internal combustion engines, intermediate engines, pneumatics or pressure. Indirect combustion vessels use the large flame in multiple fire tubes to raise the temperature of another fluid in the intermediate container through a heat transfer device. Indirect heating containers use a fluid carrier such as gas, water, oil or other added medium to increase the temperature of another fluid. It is a container or heat exchanger. SY/T 4805-92 Manifolds and header systems selectively direct fluids from one or more sources to one or more outlets, pipelines, gates, etc. The pipeline from the fittings is connected to the pipes. Each manifold is connected to the pipes and directly sent to the production system.
The manifold is also called the port to distribute the common gas source, water source or other fluid mechanical equipment area. The area where the internal combustion engine gas turbine, motor, generator, pump, compressor and other rotating or reciprocating mechanical equipment are installed.
The personnel and public system area is the production area and the area of public service equipment. The personnel landing platform is a small platform used for personnel to get on and off the ship in the offshore section. The pressurized buffer tank is a container with positive pressure to prevent the liquid from entering the pump blades and causing dust fluctuations. Protective wall is a barrier designed to resist any falling or flying objects or to prevent them from rotating, and to prevent the flow of gases from one area to another, and to limit local explosions:
Pump A rotary or reciprocating barrier device including a transmission device and associated pipelines, valves, and buffers, used to transport gases,
Flare system A system that releases natural gas from a pressurized system to the atmosphere during normal operation. The release can be continuous or intermittent, and can be done either in a staggered or intermittent manner. The natural gas emergency release system is used to automatically or automatically release natural gas from a pressurized system to the atmosphere, and is used to relieve abnormal high pressure conditions.
Separator A flare pressure vessel used to separate natural gas and various liquids by the drop in specific gravity or centrifugal action. Separator Separators are usually round (vertical, vertical) or spherical. Flameless operation area is an area where process equipment of the original flame path is placed. The wellhead controls the fluid from the production meter or water injection river with an assembly of valves and pipe fittings, usually including casing head, tubing head, upper valve (one or more), wing valve and automatic closing valve, as well as flow control valve and inner nozzle. There are usually several parallel valves on the upper structure. Wellhead area is the area around the well (one or more). Chapter 3 Regulations, Rules and Regulations
