Where Performance & Safety Matters
Where Performance & Safety Matters


Capability Requirements

An organisation requires a system-of-systems to successfuly deliver it's defined capability. This capability defintion may be delivered via Operational Analysis [OA] to objectivly define the capability. From this, system specifications can be produced against which equipment and support can be designed, tested, acquired and maintained. One of the essential aspects of this process is the effective integration of the multiple systems.

Systems Integration

The human operator works together with the craft and its systems to deliver optimal performance.  Effective integration can be achieved when the design of the craft and its systems are focussed on the characteristics and abilities of the human and the team.


The adoption of Human Systems Integration [HSI] / Human Factors Integration [HFI] provides a framework for organisations to maximise their operational capability. The HSI / HFI Domains include:

  • Personnel
  • Training
  • Human Factors Engineering / Ergonomics
  • Survivability
  • Environment
  • Safety
  • Occupational Health
  • Habitability


Examples of HSI development work undertaken by 20KTS+ staff includes:

  • Dobbins, T., Horton, J. and Scott, R. (2014) Defining Operational Envelopes To Support Human Systems Integration Within Fast Craft Design. Conference proceedings; RINA Human Factors Conference. London, UK.
  • Dobbins, T., McKesson, C. and Stark, J. (2012) Embedding Human Systems Integration within Marine Systems Engineering. Conference Proceedings; RINA Systems Engineering in Ship & Offshore Design Conference, London. March, 2012.

Human Factors Engineering [HFE]

HFE, or ergonomics is an essential part of HSI / HFI process. A globaly recognised resource supporting the design and development of craft capable of speeds of 20KTS+ is the High Speed Craft [HSC] Human Factors Engineering [HFE] Design Guide.

Test & Evaluation [T&E]

The acquisition / procurement of equipment may appear simple but unfortunately the sector is strewn with examples of poor craft and systems that got through the acquisition process. In these circumstances it is true that 'you get what you ask for'. It is essential to write the Statement of Requirement [SOR] or tender documents on quantifiable terms that can be subsequently tested to ensure the system is compliant with the requirement. If it isn't, it can then be rejected. 20KTS+ staff have supported both of these processes; the requirement definition, including the use of the HSC HFE Design Guide [see above] and the training of T&E staff via the Test Coxswain / Engineer Course.

It's all about the Command & Control [C2] - NOT the boat


Training doesn't just happen - it is designed by experts to deliver the competencies and proficiencies that the boat crews and support staff require. By undertaking a Task Analysis [TA] and susbsequent Training Needs Analysis [TNA] the training designers can then produce the training curriculum and assessments, inlcuding the equipment used to support the training, e.g. simulators and specific training craft.
