Scope: This standard specifies the environmental conditions and safety requirements for offshore sites, submarine cable and pipeline routes, and onshore sites of ocean wave power plants. This standard applies to the planning, design, construction, and operation of ocean wave power plants.

Introduction

GB/T 36999—2018: Professional interpretation of environmental conditions for ocean wave power stations

Background of standard formulation and analysis of technological evolution

With the growth of global energy demand and the focus on renewable energy, ocean wave energy has attracted much attention as a clean energy source. The formulation of GB/T 36999—2018 "Environmental conditions for ocean wave power stations" aims to regulate the construction and operation of ocean wave power stations and ensure their safety and sustainability.

This standard was proposed by the State Oceanic Administration and is managed by the National Technical Committee for Marine Standardization. The drafting unit of the standard is the National Marine Technology Center, and the main drafters include Wang Xin, Wang Jing and other experts. The standard was drafted based on the rules of GB/T1.1-2009 and combined relevant technologies and practices at home and abroad.

Comparison of standard frameworks

Dimensions	GB/T 36999—2018	International similar standards	Local standards
Scope	Covering environmental conditions requirements for offshore sites, submarine cable pipeline routes and onshore stations	IEC/TS 62600 series standards focus on power characteristic evaluation	NB/T31006 focuses on steel structure corrosion protection technology
Core requirements	Monitoring and analysis of environmental factors such as waves, currents, water depth and submarine geology	Emphasis on the safety and durability of marine engineering	Focus on regional specific environmental protection measures
Technical requirements	13-month continuous observation period, 5-year, 10-year, 20-year, 50-year recurrence period analysis	International standards focus on the reliability of long-term monitoring data	Local standards emphasize regional adaptability

Implementation recommendations

Recommendation 1: Establish a long-term monitoring network

Set up no less than 1 long-term wave observation point and 1 tide station within the site of the wave energy power station.
Combining historical data and on-site observations, analyze the safety of the device deployment location.

Suggestion 2: Strengthen the protection of submarine cables and pipelines

Set up a 50-meter protection zone on both sides of the submarine cable and regularly check the anti-corrosion protective layer.
Strictly select the optimal routing plan in accordance with GB/T 17502.

Suggestion 3: Optimize environmental control in onshore stations

Set up air-conditioning systems according to the requirements of functional areas to ensure that the temperature and humidity meet the requirements of GB 50019.
Strengthen fire prevention, lightning protection and anti-corrosion design to ensure the safety of onshore facilities.

Suggestion 4: Improve safety protection level

Install lightning protection devices in accordance with GB 50601 to prevent lightning disasters.
Equip with a complete fire-fighting system and emergency facilities to ensure personnel evacuation and equipment protection.
Steel structure anti-corrosion treatment is strictly carried out in accordance with NB/T31006 standard.

Conclusion

The implementation of GB/T 36999-2018 "Environmental Conditions Requirements for Ocean Wave Energy Stations" is of great significance to promoting the development of marine energy in my country. By strictly following the technical requirements and safety regulations in the standard, the safe operation of ocean wave energy stations can be effectively guaranteed and the effective use of clean energy can be promoted.
