About Rockatek

Rockatek Ltd is an Engineering Consultancy based in Gloucester in the United Kingdom, offering Analysis, Design and Testing services across a wide range of industries.

Rockatek specialises in Engineering solutions for harsh environments. Its mission is to use experience and expertise to develop and enhance clients’ products, systems and processes to provide cost efficient solutions. Rockatek also offers a Forensic Engineering consultancy and a robust in-house verification test service to verify complex design analyses and to demonstrate known failure modes to clients.

The company was established in 2016 by three experienced Chartered Engineers (MIMechE) with more than 35 years combined experience in Mechanical, Electronics and Systems Engineering. This is achieved by combining all the necessary disciplines including a First Principles approach to Engineering, Mathematical Modelling and Finite Element Analysis (FEA), Computer Aided 3D and 2D Design (CAD) and Project Management.

Rockatek’s philosophy is to work closely with clients with a focus on Project Management from design and analysis, through the supply chain to prototypes, qualification testing and Operations. To ensure the service is executed at the highest possible standards, Rockatek operates an ISO 9001:2015 certified Integrated Quality Management System. See the Rockatek ISO 9001:2015 certificate here.

Operations and Project Management

Rockatek’s consultants are competent in all aspects of Operations and Project Management. In order to maximise efficiency, Rockatek operates a lean Design and Engineering service from concept generation to project handover.

Rockatek projects are controlled through an internal stage gate process in line with customer requirements. Staged solutions are offered as well as formal design and progress reviews before progression to the next project phase. Each project is assigned a dedicated Engineering Consultant to manage the project through to completion.

Rockatek uses a robust Product Data Management (PDM) system to manage document configuration and to control design changes. This configuration control process extends to specifications, CAD models, drawings, assemblies, bills of materials, design standards and technical reports.

Rockatek offers an Operations and Project Management consultancy service. Our consultants can assess a client’s existing systems and process controls and highlight areas for refinement and improvement. Rockatek will typically investigate performance to existing KPIs and KFIs and provide feedback on the effectiveness of existing measures. This is a bespoke service tailored to the client’s needs and as such, requires a detailed initial discussion with the client’s management team as the scope can vary considerably.

Rockatek also offers a Supply Chain Management service targeted at the procurement of complex engineering components. Typically, such components will require a number of subcontract process steps including specialist machining, heat treatments, surface treatments and NDT.


“ABI Engineering have worked with the guys from Rockatek for over 10 years. They are experienced and extremely capable with 3D and 2D design and have a clear understanding of Design for Manufacture principles. We have worked with them on numerous projects to develop repair procedures for high value components after use. Their core engineering skills and innovative approach usually bring excellent results. The Rockatek guys are excellent, Mechanical Engineers who are professional and responsive. Cannot recommend them highly enough”.

“We used Rockatek to carry out calculations and mechanical simulations of our Biomass Filter Vessels. End user requirements meant loading conditions had to be analysed to establish product limitations, including at elevated temperatures. Rockatek provided analysis results and where required, offered design improvements to increase product capability. The work was carried out professionally, on time and was reported clearly. We would recommend Rockatek to anyone wanting to increase their product capability with verified and tangible mechanical engineering analysis”.

“Lee Products Ltd has worked with the Directors of Rockatek for over fifteen years in the Down Hole Oil Tool market, specifically in the field of high pressure hydraulics. Jim, Dan Crowley and Dan Minett-Smith have the technical knowledge, vast experience and commercial acumen to give any project tangible results.

The one thing that impresses me most in B2B is when smart engineers/innovators can communicate ideas, data, and give succinct, understandable explanations of complex systems to any audience. These guys can do this in abundance and do it with passion and enthusiasm. We look forward to working with Rockatek again”.

“I have worked with James and the team at Rockatek Eng Consultants recently, their approach to solving engineering problems is effective and efficient. The engagement with them has been very professional at all times. They have an extensive knowledge of the ANSYS suite of simulation, and clearly demonstrate this with a pro-active and efficient approach to engineering tasks. If you require engineering simulation then I would encourage you make contact with the team at Rockatek Engineering Consultants”

“As a consultant to the Downhole Engineering and Operations segments of the Energy sector primarily in Oil & Gas Exploration, I am required to present competent service, components and support. I require recognised, technical and engineering support in system, procedure and component design, material selection, analysis, qualification and verification. I have worked with the team at Rockatek in their past roles to support my position and work scope. That past relationship and now their documented and quantifiable abilities and competence has allowed me to endorse Rockatek Ltd as a preferred vendor in support of my company going forward.”
