In the long-term services of offshore engineering structures, it is inevitable to be affected by the complex offshore environment, which may lead to a reduction in local or overall structural strength. The research on structural health monitoring of offshore engineering structures can detect damage in time, which is of great significance to ensure the normal offshore operations, and is also an important part of the integrity management. In this paper, existing methods and techniques for identifying offshore environmental parameters are reviewed. Then, the analysis of offshore dynamic response is mainly summarized in terms of modal parameter identification, motion status, and strain/stress monitoring. Damage identification methods for offshore structures in terms of corrosion, cracks, and local strength reduction are introduced. Finally, some suggestions for future research on offshore structural health monitoring are put forward. This paper presents a review of existing technologies in structural health monitoring for offshore engineering, with particular emphasis on research into dynamic response monitoring and damage detection. The aim is to provide references and guidance for practical applications in related fields.
