Offshore crane operator course. Stage 3
This course is for candidates who have completed OCO Stage 2 and gained sufficient registered operating time on offshore cranes.
This section provides a summary of the assessment process at Stage 3 level where the candidates assessed on his skills as a crane operator.
The candidate is fully briefed on the assessment format but does not receive any form of prior tuition, unless the assessment is being delivered in conjunction with a training programme.
Crane Operator Stage 3 Assessment Format
The Assessor will accompany the crane operator into the cab and ask the operator to "familiarise" him with the crane as if he were handling it over to a new member on board. Points to be noted will include, but not be limited to:
- use and understanding of load indicator functions, both static and dynamic modes
- limiting devices
- drive train
- wires fitted to the crane in use
- crane controls
- understanding of the crane operator's responsibilities under LOLER regulations or prevailing legislation
Through the caliber of response, the assessor can identify any areas of weakness in the operator's knowledge of the equipment, safety systems or company operating procedures.
The practical assessment will be structured, where possible, around normal operations, scheduled to coincide with the arrival of a supply vessel.
The Instructor will visually check whether the system has been adjusted to reflect differing operating criteria, i.e. sea state, then leave the cab and observe.
The operator will undertake a series of lifts to demonstrate his ability to:
- operate the crane in a safe manner, displaying awareness of any conflicting activity
- control the crane whilst operating unloaded and with load on hook
- demonstrate the ability to remove swing from the load
- follow instructions given by the banksman through hand signals and radio contact
Following liaison with the client representative, a suitable opportunity will be identified for the crane operator to complete a multi-choice theoretical examination to identify the extent of his underpinning knowledge of crane operations. The minimum pass mark is set at 80%.
Successful completion of the assessment process allows operators to carry out all lifts unsupervised
Requirements
Personnel with Stage 2 and further experience under supervision or with proven verifiable experience

Today I’ve passed the re-assessment OCO stage 3 course in LERUS Training Center Bulgaria. My assessor’s name was Anton Matveyev. I stayed satisfied of all aspects of the training. Theoretical part is complete. We had thorough discussion regarding all key aspects of crane operations and maintenance what definitely helps to realize questionnaire on theoretical exam. The practical facility is also quite realistic. I’ve been fulfilling quite similar tasks to real operations at sea. In general its friendly atmosphere all around starting from reception and closing with delicious lunch on demand which is included in the price of the course.
Good luck to you guys in your heavy and useful work! Will definitely come back to you again in two years. (Posted on 8/14/2025) - Thank you!

I am very pleased with the training center. Organization of the educational process, personnel, especially instructors assessors. The whole process, both training and practical, is at a high level. Technical capabilities provide a complete picture of the real situation, which allows you to completely immerse yourself in the reality of the situation.
