National Marine Comprehensive Experimental Field Weihai
The National Marine Comprehensive Field Weihai (here forward referred to as Weihai) is part of a larger test network off the coast of China referred to collectively as the National Marine Test Site. The four marine facilities are operated by the National Ocean Technology Center (NOTC) and stretch most of the length of China's coastline. The layout of the facilities is intended to service the Northern and Southern Coastlines as well as provide unique testing sites for shallow and deep water. While the NOTC claims marine activities in the areas began as early as 2009, the formal versions known today were officially compiled in May of 2018 by the NMTC and approved by the the Ministry of Natural Resources.
Weihai specifically had its construction plan agreed upon and signed September 24 2021 and was the first of the marine test sites jointly built by the ministry of natural resources and local governments. As far back as 2016 however, a roughly five square km area had been reserved and certified for the public testing of a diverse set of testing interests from general marine equipment, observation/monitoring systems, wave energy and tidal energy. The area is divided into three categories, offshore, shore and island testing. The zone is located in the Northern waters of Chu Island and considered the "shallow water" test site with the average water depth measuring around 45 meters, though a trench cutting east-west north of Chu island can reach depths of 70 m. Currents in the test zone have been measured at peak speeds of up to 1.2 m/s and average speeds of 0.4 m/s.
Since the the signing of the construction plan, an anchored test platform, a buoy test platform, a background field monitoring system, a data management service system, and a public service system have been built on site. Additionally a substation for the test site has been constructed on the mainland coastline for Weihai. Additional shore based facilities to support testing and site management are in the process of construction. As of 2022, 48 sea trials have been conducted.

Site Characteristics
Geographic characterization for the test site location:
- Open Ocean: Main body of ocean, not enclosed or partially enclosed by land
- Coastal: Open water near the coast, spanning between land and shelf boundary
- Enclosed Bay: water that is partially surrounded by land, with a mouth open to larger water
- Constricted Channel: A channel where water flows quickly due to narrowing by the land
- River: Water flowing from land towards a larger body of water
