API RP 90-1, 2nd Edition, August 2021 - Annular Casing Pressure Management for Offshore Wells

This document provides guidance for managing annular casing pressure in offshore wells of various types to ensure that well integrity is maintained, and risks are managed. It is similar in scope and purpose to API 90-2, which addresses this annular casing pressure management for onshore wells.

This document is meant to be used for existing offshore wells that exhibit annular casing pressure, including thermally induced casing pressure, sustained casing pressure (SCP) and operator-imposed pressure. It contains general information regarding annular casing pressure that is applicable to all offshore well types: fixed platform wells, subsea wells, hybrid wells and mudline suspension wells. Many risks are the same between well types, so much of the information has been collected into single sections that apply to all of them. Where necessary, information about individual well types is separated for clarity.
