At 3P Tech Serv, we deliver specialist engineering services for equipment manufacturers — acting as a trusted design engineering partner for OEMs who need reliable, technically capable engineering support without the overhead of expanding their in-house team.
Engineering Services for Equipment Manufacturers
Our engineering services for equipment manufacturers cover the full mechanical engineering scope needed to support OEM design and production — including equipment design calculations, 3D CAD modeling, 2D fabrication drawings, stress analysis, and design documentation. We work across a broad range of equipment types including pressure vessels, heat exchangers, skid packages, storage tanks, and specialist mechanical assemblies — providing the engineering depth and bandwidth that manufacturers need to win and deliver contracts efficiently. Whether you need support on a single project or ongoing engineering capacity across your product range, our team is structured to deliver consistently and reliably.
Design Engineering Partner for OEM
As a dedicated design engineering partner for OEMs, we go beyond simply producing drawings and calculations — we become a genuine extension of your engineering team. We take the time to understand your product range, your design standards, and your clients' requirements, so that the engineering we deliver fits seamlessly into your workflow and reflects the quality your customers expect. Our partnership approach means you get consistent engineering output from a team that understands your business — reducing the time you spend on briefing, reviewing, and reworking outsourced engineering deliverables.
Mechanical Engineering Subcontracting Services
Our mechanical engineering subcontracting services provide OEMs and manufacturers with a flexible, scalable engineering resource that can be deployed quickly and scaled to match your project pipeline. We handle the full mechanical engineering scope — from concept and preliminary design through to detailed calculations, fabrication drawings, and design documentation — working to your standards and under your quality management framework. Our subcontracting model gives you the engineering capacity you need when you need it, without the fixed costs and management overhead associated with permanent in-house headcount.
Back Office Engineering Support
Our back office engineering support services provide OEMs and manufacturers with dedicated, behind-the-scenes engineering capacity that supports your front-end sales and project delivery teams. We handle the technical engineering workload that sits behind your client-facing activities — including design calculations, drawing production, material take-off, design reviews, and technical documentation — freeing your senior engineers to focus on client relationships, project management, and business development. Our back office engineering support is structured to be invisible to your clients while being indispensable to your operations.
Contract Engineering Services for Mechanical Applications
Our contract engineering services for mechanical applications provide a structured, deliverable-based engagement model for OEMs and manufacturers who need engineering output on defined terms — with clear scope, timeline, and quality expectations agreed upfront. We work to your project schedule and deliverable register, providing regular progress updates and early flagging of any technical issues or scope clarifications needed. Our contract engineering model gives you full visibility and control over the engineering process while benefiting from the technical depth and bandwidth of an experienced specialist engineering team.
Offshore Engineering Support Services
Our offshore engineering support services provide specialist mechanical engineering capability for OEMs and contractors working on offshore oil and gas, floating production, and subsea projects. We are experienced in the specific engineering requirements of offshore equipment design — including weight and centre of gravity constraints, marine environmental loading, offshore material and coating specifications, and the stringent documentation and verification requirements of offshore certification bodies. Whether you need support with equipment design calculations, structural analysis, or fabrication drawing production for offshore projects, our team provides the technical depth and offshore awareness needed to deliver to the required standard.
