Well control: well control equipment course for floaters.


The Well Control Equipment Course (WCEC) is an intermediate well control equipment course and has been specially developed for drilling personnel wishing to gain basic overall skills in well control on floating drilling rigs.

Lloyd’s Register, a global leader in providing knowledge, expertise and high quality training services throughout the drilling industry, offers an extensive training programme focused on developing the technical skills and abilities of toolpushers, drillers, assistant drillers and mechanics who are involved in operating or maintaining well control equipment on floating rigs.

Our well control equipment training accommodates all experience and skill levels. All courses in this curriculum are International Association of Drilling Contractors (IADC) accredited and tailor-made for personnel seeking additional professional training to perform correct and safe operations involving well control equipment on offshore drilling rigs.

You will learn to

  • Describe and explain the operation of a floating rig's main well control equipment:

    • ram type BOPs (blowout preventers)

    • shear ram calculations

    • annular-type BOPs

    • BOP installed gate valves

    • hydraulic connectors

    • choke and kill manifold

    • BOP HPU (hydraulic power unit)

    • conventional BOP control systems

    • multiplex BOP control systems

    • diverter systems

    • well control equipment mathematics

  • Describe and explain the operation of conventional hydraulic and modern deep-water multiplex control systems

  • Calculate the usable volume of accumulators, both surface and subsea

  • Calculate riser space-outs, perform riser tensioner calculations and drill pipe space-outs compressibility calculations

  • Test BOPs, both surface and subsea

  • Test choke and kill manifolds

  • Perform poorboy degasser calculations

  • Explain the implication of standards (American Petroleum Institute - API, America Society of Mechanical Engineers - ASME, etc.) on maintenance, inspection, function and pressure testing of well control equipment

  • Identify recurring problems with subsea well control equipment

Course Content

  • The function, operation, inspection and the most frequent problems of:

    • ram type preventers and their locking systems

    • shear ram calculations

    • annular type preventers

    • BOP gate valves fail-safe type

    • choke and kill manifolds

    • hydraulic connectors for shallow and deep water operations

    • conventional hydraulic BOP control systems

    • multiplex BOP control systems

    • diverter systems

  • Norms and standards (such as API) used in the drilling industry and their implication for well control equipment

  • Safe-working procedures and requirements for pressure testing of the BOP equipment

Your future development

The Well Control Equipment Course (Floating rigs) is fully accredited by the International Association of Drilling Contractors (IADC).

Upon successful completion of the course, candidates receive a certificate of completion which is accredited by the IADC. This certificate is valid for five years.

This course is the second level our multi-level educational curriculum. Candidates who have successfully completed this training course and would like to extend their knowledge might also be interested in attending our advanced-level Deepwater Challenges Course.

Suitable for

This course is intended for personnel involved in drilling operations and working with well control equipment on floating rigs who want to improve their knowledge of well control and subsea-engineering related equipment:

  • Rig Managers

  • Drilling Supervisors

  • Toolpushers

  • Drillers

  • Experienced Assistant Subsea Engineers

  • Subsea Engineers

  • Senior Subsea Engineers

Course content

The 5-day course is based on interactive classes with ample time for group participation and discussion. It also includes:

  • Videos to explain operational and maintenance procedures

  • An entry test to evaluate candidates’ knowledge prior to the start of the classroom sessions

  • A final exam at the end of the course, with a minimum passing score of 70%
