What is Human Factors?
Definition
Human Factors is a scientific discipline that applies systematic methods and knowledge about people to evaluate and improve the interaction between individuals, technology and organisations.
The aim is to create a working environment (that to the largest extent possible) contributes to achieving healthy, effective and safe operations.
![Page 24: Offshore experience in assessing Human Factors in the design of … · 2017. 3. 7. · Why do we need HF-Assessment Method? Challenges today and in the future -(2) Consequences •](https://reader035.vdocuments.net/reader035/viewer/2022071014/5fcd81d7d8f3a11abb4b95ca/html5/thumbnails/24.jpg)
Why do we need HF-Assessment Method?
Challenges today and in the future - (1) Key Trends
• Requirements for profitability in (re) design and operation
• Reduced manning - Increased task complexity
(single control centre - several platforms/processes)
• Multi-skilled teams
• Increased automation (number, type of sensors/signals)
• Introduction of new technology - new ways of working
• Regulatory - Continual improvement of HSE
• Reduce risks/ (barrier philosophy) Human Error in focus
![Page 25: Offshore experience in assessing Human Factors in the design of … · 2017. 3. 7. · Why do we need HF-Assessment Method? Challenges today and in the future -(2) Consequences •](https://reader035.vdocuments.net/reader035/viewer/2022071014/5fcd81d7d8f3a11abb4b95ca/html5/thumbnails/25.jpg)
Why do we need HF-Assessment Method?
Challenges today and in the future - (2) Consequences
• Achieve consistent user interface (old / new / various)
• Develop user friendly control systems - (efficient
navigation, task based, give overview, ++)
• Ensure different systems support operator (common alarm
presentation, prioritisation, grouping, comprehensible,++)
• Ensure acceptable workload (amount, complexity, etc).
• Develop relevant procedures (access, realistic, useable)
• Ensure systematic and effective end user involvement

What is the HF Assessment Method?
Goals for the method
A systematic Validation and Verification (v&v) method forreviewing :
- Process integration of HF in design & operation- Evaluating the results of the process
In Offshore Control Centres (drillers cabin, cranes, offloader cabin, local and central control room, etc).

What is the HF-Assessment Method?
The Overall objective is to:Improve HSE level in Control Centres• Reduce possibility of human error• Optimize workload• Increase safety in all situations
Increase business perfomance and regularity in production,optimize production rates and lower training costs
Developed for NPD by HFS in co-operation with industry

HF-Assessment Method structure
HF-Assessment Method consists of 2 main parts
1. Introduction - to HF-assessment method
2. Checklists - covers min. of requirements for HF in CR
- Documentation checklist
- General checklist covers all design phases
- Specific checklists for each phase in design process
