Qualified Rigger

A rigger is anyone who attaches or detaches lifting equipment to loads or lifting devices. In order to be considered a Qualified Rigger, the person shall have successfully completed a rigger-training program in accordance with Appendix A3. The minimum requirements for a Qualified Rigger are outlined in detail in 3.1.4 and Appendix A3. A Qualified Crane Operator is also a Qualified Rigger.

Qualified Inspector

Qualified Inspector

Definition(s)

Qualified Inspector

A person so designated by the employer who by reason of appropriate experience and training, has successfully completed classroom-type training on crane maintenance and troubleshooting; on hoist troubleshooting and overhaul; and on the structural aspects of offshore cranes, which gives a knowledge of structurally critical components and critical inspection areas. These minimum training requirements are outlined in Appendix A2. Additionally, individuals recognized by regulatory authorities (“Authorized Surveyors” or “certifying authorities”) may conduct inspections of cranes pursuant to this edition, provided they meet the requirements of Appendix A2. With successful completion of this minimum training supplemented with requalification at a minimum of every four (4) years, the inspector is considered qualified to perform the Initial, Pre-use, Monthly, Quarterly, and Annual Inspections. The scope of these inspections is outlined in 4.1.2. It is not a requirement for a Qualified Inspector to also be a Qualified Crane Operator. However, a Qualified Inspector is not a Qualified Crane Operator unless they have also completed the requirements of a Qualified Crane Operator (see 3.1.2), including the physical outlined in 3.1.2b and Appendix A1.

Qualified Crane Operator

A person so designated by the employer who has appropriate offshore experience and training. Such appropriate experience and training must comprise minimum amounts of classroom-type sessions and hands-on field training, on cranes specific to the type of crane to be operated by the qualifying Crane Operator. These minimum requirements are outlined in detail in 3.1.2 and Appendix A1, Crane Operator Training. This RP should be followed to qualify Crane Operators of two crane types: 1) operation of non-mechanical cranes and/or 2) operation of mechanical cranes (those with freefall capability). With this minimum training, qualifying Crane Operators should be qualified to safely operate the crane(s) on which they have been trained. Also, with this minimum training, the qualifying Crane Operator should also be sufficiently qualified to perform the crane inspections outlined in 4.1.2, with the exception of the Initial, Quarterly, and Annual Inspections. Crane Operators will remain qualified to operate the cranes on which they have been trained, provided they successfully complete the refresher training requirements outlined in 3.1.2d.
