It's also designed to work in concert with other industry standards. For instance, specific requirements for topsides structures are in , for marine operations in API 2MOP , for arctic environments in API 2N , and for site-specific jack-up assessment in ISO 19905-1 .

The American Petroleum Institute (API) publishes the industry's most authoritative guidelines for offshore structural engineering. For engineers and project managers working on fixed offshore platforms, is an essential document. This guide will walk you through everything you need to know about this critical standard—from its technical scope to how to obtain an official copy.
