Drilling equipment is a giant equipment in the upstream of offshore oil industry. As the core of offshore drilling rig, the lifting system is a very complex mechanical vibration system, its working performance directly affects the working performance of the whole rig. In order to ensure the safety of offshore drilling, we must explore the common mechanical problems and improvement measures of offshore drilling rig lifting system. This paper mainly analyzes the mechanical failure of winch, traveling system and derrick, and then proposes some improvement measures to effectively prevent these mechanical failures.
