API RP 2EQ, titled “Planning, Designing, and Constructing Fixed Offshore Wind Structures in Transition Zones and Intermediate Water Depths,” is a recommended practice developed by the American Petroleum Institute (API). While API is historically rooted in oil and gas, RP 2EQ has become a cornerstone standard for offshore wind energy projects, particularly along the U.S. Outer Continental Shelf and in global markets that adopt API standards.
The document bridges the gap between conventional offshore oil-and-gas platform design (API RP 2A) and the unique requirements of offshore wind turbine generators (WTGs). It addresses:

Offshore platforms are critical infrastructure for the extraction of oil and gas from beneath the seabed. These structures are exposed to harsh marine environments, including extreme waves, strong currents, and, in certain regions, seismic activity. Earthquakes pose a significant threat to offshore platforms, as they can cause structural damage, lead to oil spills, and even result in the collapse of the platform. Therefore, designing and analyzing these structures to withstand seismic forces is essential for their safe operation.
If you are looking for the "updated" version, it is crucial to understand the philosophical shift the API has made in recent years.
Historically, offshore standards were highly prescriptive—telling engineers exactly what to do. The modern updates to the API 2 series (including 2EQ) have moved toward Performance-Based Design. API RP 2EQ, titled “Planning, Designing, and Constructing
This means the updated standard places a heavier emphasis on:
API Recommended Practice 2EQ (API RP 2EQ) is titled "Planning, Designing, and Constructing Floating Production Systems."
While API RP 2A-WSD covers fixed offshore platforms, RP 2EQ specifically addresses the unique challenges of floating structures. It provides comprehensive guidelines on: If you are updating your PDF library, here
Imagine you are designing a monopile foundation for a 15 MW turbine in 35 meters of water, 20 miles off the coast of Virginia. Using the previous edition of RP 2EQ would lead you to use a static equivalent load for the rotor thrust. The updated API RP 2EQ PDF requires a time-domain coupled analysis (aero-hydro-servo-elastic) for all turbines above 10 MW. This change alone has major implications:
Failing to use the updated version would result in a design that is non-compliant with BOEM (Bureau of Ocean Energy Management) permit conditions.
