comment no 1 chapter 2 page 5 last paragraph
Comment No 1: Chapter 2, Page 5, last paragraph
  • Nosok s-002 is described to constitute of only prescriptive requirements.
    • The standards constitute both prescriptive and goal-oriented requirements. The document fails in describing how the projects shall address and implements the goal oriented requirements in the projects.
comment no 2 chapter 3 page 6

The activities described in Norsok s-002 is described in chapter 3 (and the following chapters) as list of activities.

The systematically follow-up of WE according to PSA and NORSOK requirements require an interaction between the activities – they are not a list of proceeding activities.

  • The NORSOK standard require the WE competence and resources to be stated in an early stage.
  • Resources allocated to a typical development project (FEED and detailed engineering):
  • WE resources design team
  • Technical working environment, ergonomics (full time)
  • Human Factors (full time)
  • Acoustics ( full time)
  • + other specialists
  • Company
  • Technical working environment (full time)
  • Human Factors (full time)
  • Acoustics (part time)
  • Ergonomist (part time)
slide7

NORSOK S-002 gives an example of WE analyses and when they preferable should be conducted in a normal project

A so-called ”fast track” project might impose special issues – this is not considerate in the document.

The interaction between the activities are not considered.

slide8

Managing and follow-up of WE in design and new-buildings are a continues process that could not be reduced to single work shop activities.

The analyses and activities listed needs carefully planning, information gathering, expert analyses, discussions and interactions with all parties (designer, worker representatives, discipline leaders, Company, PSA etc.). The suggested work shops are to be regarded as verification activities – not as the main activity.

slide9

Work shops are described as the major way of working.

    • Managing and follow-up of WE in design and new-buildings are a continues process that could not be reduced to single work shop activities.
    • The analyses and activities listed needs carefully planning, information gathering, expert analyses, discussions and interactions with all parties (designer, worker representatives, discipline leaders, Company, PSA etc.). The suggested work shops are to be regarded as verification activities – not as the main activity.
