Submitted by Nexen Petroleum U.K. Limited


  • Nexen Petroleum U.K. Limited reduced non-productive time associated with “Green Hats” inductions by 11% – saving approximately £500,000.
  • Improved safety on the platform and enhanced business continuity with experienced personnel returning to do work on the assets.

Description of Best Practice

Nexen set out to reduce the productive time lost through the volume of inductions for personnel unfamiliar with their North Sea assets – otherwise known as “Green Hats”.

Ensuring the safety and wellbeing of the workforce is central to Nexen’s core values and culture.  Workers across all platforms receive a thorough induction, welcoming them to the installation and preparing them for their role onboard. This includes safety training specific to each platform, together with an understanding of the company lifesaving rules and culture, before embarking on their job. This induction is mandatory for personnel who are not platform familiar or have not been on the platform within one year.

Each induction session involves an average of 19 hours of training and support which includes approximately;

  • 8.5 hours platform familiarisation for each “Green Hat”
  • 2 hours induction session by core crew
  • 8 hours of core crew  support and shadowing as part of permit to work duty
  • 30 mins attending Offshore Installation Manager’s evening brief

When Nexen analysed the process, the company discovered the planning behind inductions could be tightened up and run more efficiently – and calculated that over 57,000 hours had been lost in 2014 through Non Productive Time.

Nexen recognises the value and skills which new personnel bring to it operations and encourages trainees and new-starts to it assets, and does not discourage this practice. For improved efficiency, requests are made to contractors that when an experienced person is being mobilised, a check is carried out to see if they are platform familiar and if they have been on the platform within the last 12 months.  This decreases the number of one-trip personnel to the assets.

Overall, this has resulted in improved safety to the platform and enhanced business continuity with the experienced personnel returning to do work on the installations.

A number of steps have been introduced to support this initiative, which range from reviewing the trip history of all personnel travelling offshore, planning workscopes around securing platform familiar personnel where possible, and the introduction of “Green Hat” figures within contractual KPIs.  This approach is encouraged across every department in the organisation, onshore and offshore, no matter how big or small the task.

As a result of this initiative, in 2015, Nexen reduced non-productive time associated with “Green Hats” by 11% and has saved approximately £500,000.
