In order to ensure the integrity and safety of deepwater risers during the development of deepwater oil and gas fields, the on-site monitoring technology of risers has become a research hot point in the field of marine engineering. Riser monitoring devices have large quality, which will change the vibration responses in practical engineering. In this paper, the vibration modality of a steel catenary riser (SCR) with monitoring devices is simulated in time domain using professional marine software Orcaflex, including static, dynamic and strength characteristics of SCR and is based on catenary method and centralized mass method. The effects of SCR vibration with and without monitoring devices are compared and analysed on the static characteristics, dynamic characteristics and strength.
