Design Engineering & Draughting

Design Engineering support at Keystone Blue is flexible, reliable, and efficient.  Regardless of the stage of your project, our team can support you with concept 3D models, FEED studies, drawing packs, design packs, analysis, and anything in between. 

Project Engineering & Management

Our approach to project support is that our clients should receive first class service.  We offer to take standalone work packs to handle in-house, reducing the workload on the client team.  We also offer on-site support and integration of our personnel into client project teams.   


CAD Utilisation & Improvements

Many companies use 2D & 3D CAD software within their engineering teams.  Although the standard may be acceptable, it is often the case that simple improvements could be made to templates which increase efficiency of model and drawing production and reduce rework.

If you have an engineering project for which you require support, you are in the right place.


Our passion for engineering is reflected in the success of our completed projects supplied around the globe. As a specialist design service provider with a strong reputation in offshore, subsea, mining, energy and automation sectors we make it our purpose to support our clients with bespoke solutions.

I have engaged with Keystone Blue across multiple projects involving pipeline repair clamps and subsea installation tools. During these projects I have found Keystone Blue to provide high quality services within budget and on time

Mike Brend – Head of Projects – Supergrip

We've been in touch with Keystone Blue on several occasions to provide us with several different bespoke furniture designs for our customers. The drawings provided have brought the piece to life for the customer and they can see what it is they're really getting. Nothing was too much trouble and no detail was overlooked, the correspondence was fantastic and we were provided with a professional result that helped us give our customers an even better quality service. Needless to say we would recommend this service to anyone!

I am more than happy to recommend Keystone Blue based on their dependable engineering support over the years. Their dedicated on-site engineer was able to adapt to our many varied projects, providing engineering solutions for conveyor systems, offshore equipment and CAD support for modular buildings. They provided their own workstation with the engineer and integrated with our systems seamlessly. Whether it is for 3D modelling work or 2D drawings, we know we can count on Key 3D, even at short notice.

Craig Chalder - Managing Director - M5Tec

Keystone Blue have supported multiple of our offshore engineering projects which have included PLET manipulators, a vessel workstation and subsea pipeline equipment. 3D models and 2D drawing packages were completed in good time and to a high standard. Key 3D have proved to be a reliable option for engineering project support and we would happily use them on future projects.
