We are a team of experienced consultants with complementary competencies specialising in the development of industrial scale projects and we:


  • confirm that business objectives can be achieved; 
  • are passionate about, understand and can balance owner needs;
  • identify risk areas and opportunities and propose mitigating plans;
  • add most value when we work from a position of trust, as part of the owner’s team, during the early stages of project development.


OTC consultants comprise a group of business managers, functional specialists, senior engineers, project managers and experienced general managers.  Each prior to joining OTC were employed in executive, senior and specialist positions at major companies, leaving them with an extraordinary depth of business, project and technical acumen.

The cumulative, relevant experience of the consulting partners exceeds 300 years, with many more specialised disciplines represented through our network of independent consultants and associates.


Our mission is to help owner teams and business managers become more effective by supplying expert advice, toolkits, training and support.

We help you create business value:

1. Owner organisations wanting to develop industrial scale projects are looking for access to experienced resources who intimately understand the industry, can mobilise quickly  and have proven project execution capabilities.

2. Entrepreneurs are also looking for a partner willing to share some of the risk during project development, who has access to a wide network and who can assist with securing project finance.

3. Financiers are looking to mitigate their exposure to risk by tapping into the knowledge of independent professionals who understand the practicalities of developing an industrial scale venture and running it successfully.

No matter the stage of the project development or operations, in order to create a successful new business you will need to use the best proven methodologies for:

  • Business case evaluations and benchmarking.
  • Business development services.
  • Process and technology know how.

    “Success” is much more than delivering a project on time and on budget. The resulting business needs to be profitable and sustainable.  This requires close attention  throughout the life-cycle:

    • Digitisation and automation related services.
    • Business and operations optimisation.
    • Independent audits and reviews of internal processes.
    • Analysis and troubleshooting.

    • Develop projects together with prospective developers/owners.
