Office for Coastal Management, 2023: Offshore Wind Technology Depth Zones,

Item Identification

Title: Offshore Wind Technology Depth Zones
Status: Completed
Publication Date: 2019-05-16

These data represent coastal bathymetric depth, measured in meters at depth values of -30, -60, and -900. Technology has been demonstrated on a commercial scale in shallow zone depths (0-30m) with foundation types including monopile, gravity base, and suction buckets designs. In the transition zone (30-60m), technology has not been demonstrated on a commercial scale. However, several small scale projects have been successfully installed and commissioned, with foundation types including tripod, jacket, and tripile designs. Several pilot projects have been successfully demonstrated in the deepwater zone (60 - 900m), with foundation types including spar, semi-submersible, and tension leg platform designs.


To support ocean planning activities pursuant to the Executive Order Regarding the Ocean Policy to Advance the Economic, Security, and Environmental Interests of the United States, the Energy Policy Act, the National Environmental Policy Act, the Rivers and Harbors Act, and the Coastal Zone Management Act.

Data Quality


The attributes in this dataset are believed to be accurate.

Horizontal Positional Accuracy:

Maximum scale of intended use is 1:80,000.

Completeness Report:

Spatial and attribute properties are believed to be complete, although attribute information has been simplified. Geometric thresholds from original data are preserved. No tests have been completed for exhaustiveness.

Conceptual Consistency:

These data are believed to be logically consistent. Geometry is topologically clean.
