Summary

On October 16, 2026 the Shantou Natural Resources Bureau published, for public comment before expert review, the sea-area use demonstration report for the Shantou Undersea Data Center Phase 1 project, naming HiCloud (Guangdong) Technology Co., Ltd. as the sea-use applicant. The report describes a commercial 7 MW offshore data-capsule platform south-east of Dahao Island powered from the Lemen I offshore wind expansion. The notice establishes a named proposal only: no sea-use right, construction consent or physical work is established. evidence

Shantou Undersea Data Center Phase 1 (7 MW data-capsule platform)

Announced last observed as of · Project announcement

Georeferenced 2025 Sentinel-2 cloudless extract (116.65-117.15E, 23.05-23.45N). Offshore wind-turbine rows and three brighter platform-sized objects (offshore substations) are visible. Used only to register the official sea-area location map; not a status observation, and the proposed data-capsule platform is not visible because it is not built. evidence

Precision scope
Centroid of the red sea-use outline (data-capsule platform, intake/outfall area and the start of the new cable) on the official sea-area location map, registered north-up to Sentinel-2 2025 imagery with two offshore-substation platforms and six turbine rows (latitude residuals at most 37 m). The chart's printed 117°00'/117°05' E meridians and 23°15' N parallel fall within about 25-125 m of their registered values. The platform is proposed and not yet visible; this is not a surveyed boundary, structure position or construction extent.
Horizontal uncertainty
Not reported

Boundary coordinates are withheld as not public. The point rests on a scanned 1:150,000 chart extract (about 37-41 m per pixel) registered to 25 m imagery; the outline spans roughly 700 x 400 m including the cable, and the unbuilt platform cannot be checked in imagery. Absolute accuracy is not established (estimated within roughly 300 m); decimal places are arithmetic precision.

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
