3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
wind power facilities
Wind power generation facilities, a general term for wind turbine generator systems and their foundations, supporting power transmission and transformation equipment, and auxiliary facilities.
3.2
wind turbine generator system (WTGS)
A system that converts the kinetic energy of wind into electrical energy.
[SOURCE: GB/T 18451.1-2022, 3.71]
3.3
offshore substation
An offshore platform within an offshore wind farm, used to house equipment such as electrical systems, safety systems, and auxiliary systems, for collecting and stepping up the voltage of the wind farm's electrical energy before transmission.
[SOURCE: GB/T 51308-2019, 2.0.5]
3.4
offshore HVDC converter station
A power engineering facility constructed in sea areas below the average high tide level of multiple years, used for AC/DC conversion, including the topside module and the foundation supporting it. Generally used for collecting and stepping up voltage of electrical energy from offshore wind farms, and for long-distance power transmission after converting AC to DC.
3.5
subsea cable
Includes submarine collector cables and submarine export cables, referring respectively to the medium-voltage submarine cable circuits within an offshore wind farm that collect electrical energy from multiple wind turbine generator systems to send to the substation, and the high-voltage submarine cable circuits connecting the offshore substation to the mainland.
3.6
mineral right
Also known as mining right, refers to the right to use mineral resources, including exploration rights and mining rights.
3.7
mining right
The right to exploit mineral resources and obtain the mined mineral products within the scope specified in the lawfully obtained mining license.
3.8
exploration right
The right to explore for mineral resources within the scope approved in the lawfully obtained exploration permit.
3.9
discovered petroleum initially-in-place
The quantity of petroleum estimated based on seismic, drilling, logging, and testing data after discovery of oil and gas by drilling. It includes predicted, probable, and proved petroleum initially-in-place. These three grades of initial in-place volume are successively ordered from low to high according to the degree of exploration, development, and geological understanding.
[SOURCE: GB/T 19492-2020, 2.3]
3.10
probable petroleum initially-in-place
The quantity of petroleum estimated for a recoverable reservoir after obtaining commercial oil/gas flow by drilling and further preliminary evaluation by drilling. Its certainty is moderate.
[SOURCE: GB/T 19492-2020, 2.3.2]
3.11
proved petroleum initially-in-place
The quantity of petroleum estimated for a recoverable reservoir after obtaining commercial oil/gas flow by drilling and confirmation through drilling evaluation. Its certainty is high.
[SOURCE: GB/T 19492-2020, 2.3.3]
3.12
integrated development agreement
An agreement signed upon consensus by a wind power construction enterprise and an oil & gas mineral right holder to promote the integrated development of offshore wind power and oil & gas exploration and production, and to support and ensure the safe and orderly conduct of offshore wind power construction and oil & gas exploration, development, and production.
3.13
fixed production platform
A platform fixed to the seabed, used for offshore oil and gas resource development and production (processing, storage, etc.). "Planned fixed production platform" refers to a platform whose installation location has been determined but whose installation has not yet been completed.
3.14
floating production unit
An offshore oil production facility that floats and is moored on the sea surface, with main functions including petroleum and natural gas development, production, processing, storage, and offloading, or only some of these functions. It includes floating production storage and offloading vessels, floating production platforms, etc. "Planned floating production unit" refers to a floating production unit whose mooring location has been determined but whose installation has not yet been completed.
3.15
subsea production system
A general term for a hydrocarbon production system consisting of all subsea equipment for oil and gas production, gathering, transportation, export, distribution, separation, boosting, pipeline connection (pipeline components), interconnection between subsea equipment (jumpers and subsea connectors), subsea injection (water injection, gas injection, chemical injection, etc.), along with their control systems and equipment, protection systems and equipment, and support structures. It extends from the subsea wellhead to the first shutdown valve landing point on the production processing facility and from the export shutdown valve of the production processing facility to the shutdown valve landing point for the submarine pipeline. Submarine pipelines are not included within the scope of the subsea production system. "Planned subsea production system" refers to a subsea production system whose installation location has been determined but whose installation has not yet been completed.
3.16
subsea pipeline and cable
Pipelines for transporting oil, gas, and water, communication cables, and power cables laid on the seabed connecting offshore production facilities or connecting offshore production facilities to onshore terminals.
4 Management Requirements for Offshore Wind Power Facilities and Oil & Gas Exploration and Development
4.1 Management of Offshore Wind Power Facilities and Oil & Gas Mining Rights
4.1.1 Construction of wind power facilities should not be carried out within the coordinate boundaries of oil & gas mining rights.
4.1.2 Planning and construction of wind power facilities within the coordinate boundaries of oil & gas mining rights shall be coordinated and implemented by the oil & gas mineral right holder.
4.2 Management of Offshore Wind Power Facilities and Oil & Gas Exploration Rights
4.2.1 Wind power construction shall not be carried out within the outer boundary coordinates of proved and probable petroleum initially-in-place of oil & gas.
4.2.2 When planning and constructing wind power facilities within the coordinate boundaries of oil & gas exploration rights, except for the scope specified in 4.2.1, opinions shall be solicited from the oil & gas mineral right holder during the planning stage. Before the construction of wind power facilities, the wind power construction enterprise shall sign an integrated development agreement with the oil & gas mineral right holder.
