Reliable engineering for demanding environments
Specialist engineers for offshore, marine and heavy industry. We take complex equipment from defined scope through design, build, testing and commissioning.

MintMech designs and delivers mechanical systems and supporting equipment for clients who need engineering that performs under real operating constraints. Consultancy-grade analysis, carried through to equipment we manufacture, integrate and commission ourselves. One organisation accountable from design to deployment.
Our work
We work where operating limits are real: offshore weather windows, vessel motion, difficult access, demanding duty cycles. The focus is delivery that works in service, supported by clear documentation and controlled execution.

Our expertise

We bring together mechanical and structural engineering, hydraulics, controls and automation, handling systems and project delivery – supported by operational awareness, so designs stay buildable and maintainable and offshore execution is considered from the outset. Equipment can be supplied with third-party certification (DNV, Lloyd’s Register, Bureau Veritas or ABS) and CE or UKCA marking as required.
Two outcomes from the platform
Products and solutions
Products
Proven kit, ready to buy or rent – heave-control and tension systems, HPUs, handling and deployment, drilling and geotechnical equipment, marine-construction kit and mining equipment.
Solutions
Bespoke engineered outcomes for complex challenges – large-diameter drilling, subsea pile installation, geotechnical rig retrofit and more, composed from the capability platform and backed by proof.
Our approach: design, build, commission
End-to-end engineering support. After exploring the options we develop the design, manage fabrication and assembly, test the equipment, deliver it to site and support commissioning until it runs as planned. We provide turnkey fabricated and assembled equipment – managing fabrication through a trusted UK and international supplier network so the right specialist does the right work, to the right quality. Work is structured to reduce project noise: clear scope, clear interfaces, defined review points, predictable delivery.
Our facility
Designed, built and tested in-house at our facility in Penryn, Cornwall. Equipment is assembled, integrated and tested before it leaves – reducing interfaces, shortening lead times and improving confidence at mobilisation. Developed with support from the UK Government through the UK Shared Prosperity Fund.

One point of accountability
When you engage MintMech, one organisation is responsible from design through to delivered, commissioned equipment. No coordination overhead handed back to you, no gaps between consultant, fabricator and installer. We carry the engineering judgement, manage the supply chain, build and test the system and stand behind the result. That single-party accountability is the heart of the offer.
Why choose us
- Innovative combinations of tried-and-tested technology.
- A proven track record.
- A full range of services to solve the problem – however niche.
- Turnkey delivery under one point of accountability – design, build, commission.
