Re-activation of ships and rigs

The key to a successful re-activation is planning. We plan, survey and perform correct re-activation of HVAC & refrigeration as well as electrical & automation systems. From pre-planning through commissioning, we ensure your systems' integrity, efficiency and final certification. 

  • Benefit from best practice; we have over 30 years' experience in surveying and maintaining offshore assets
  • Safety critical systems are put back in verified operational condition
  • Mitigate start-up risks
  • Safe and regulatory testing and regasification of the refrigeration system

Our re-activation model

The time it takes to re-activate an asset depends on the quality of the original lay-up process, any contamination during lay-up and the time the asset has been inactive. We perform a thorough survey to check the systems' condition in order to tailor the re-activation plan.

After commissioning all HVAC & refrigeration as well as  electrical & automation systems will be verified and status documented.
