At 3P Tech Serv, we understand that precision in design engineering directly impacts cost, timelines, and project success. As a design engineering partner for equipment manufacturers, we deliver detailed engineering services for OEM manufacturers with a strong focus on accuracy, efficiency, and manufacturability.
Our detailed engineering services for OEM manufacturers cover the full scope of Front End Engineering Design (FEED) and basic engineering. From meticulously crafted plot plans and detailed piping and instrumentation diagrams (P&ID) to comprehensive process flow diagrams (PFD), 2D/3D models, isometrics, and accurate material take-off (MTO), we cover all the essential elements required to seamlessly progress from the initial planning stage through to procurement and construction.
Process Engineering
Our process engineering services — delivered as part of our broader mechanical engineering subcontracting services — encompass basic and extended engineering tasks, including PFD and P&ID development, line sizing, energy mass balance, utility consumption summary, electrical load list, HAZOP, PDS, IPDS, process simulation, sizing calculations, and the preparation of intelligent AutoCAD P&ID diagrams, line lists, equipment lists, valve lists, and more.
Piping Engineering
We specialise in piping engineering designs for EPCs and engineering services for pressure equipment fabricators across industries including oil and gas, process, fertilizer, utility, renewable energy, and power. Our expertise lies in creating efficient piping solutions that adhere to international codes and standards. We provide services in piping design engineering, stress analysis, and piping support engineering.
Equipment Engineering
Our experienced team specialises in detailed engineering services for OEM manufacturers, covering the design, analysis, and improvement recommendations for various equipment types — including storage tanks, pressure vessels, towers, shell and tube heat exchangers, and more. We offer services in storage tank design, pressure vessel design, and heat exchanger design, ensuring optimal performance and compliance with industry standards.
Civil Engineering
We provide comprehensive civil and structural engineering services for the development of general infrastructure, civil foundations, and technological structures across a wide range of industries — including oil and gas refineries, petrochemicals, utilities, plant and non-plant buildings, offshore modules, skids, and more. As a mechanical engineering subcontracting services provider, we ensure safe, code-compliant, and efficiently delivered construction projects.
Electrical Engineering
We specialise in designing and engineering electrical systems for modern industrial plants. Our services encompass the creation of single line diagrams, specifications for electrical switchgear, transformers, motor control centers, starters, and more. As an engineering services partner for pressure equipment fabricators and industrial clients, we provide complete electrical project engineering — including estimation and scheduling, electrical load analysis, system architecture design, and power distribution system design.
Instrumentation Engineering
Our comprehensive instrumentation and control services encompass instrument datasheets, I/O lists, cause and effect diagrams, instrument hook-up diagrams, control room layout, DCS specifications, and more. As a design engineering partner for equipment manufacturers handling both brownfield and greenfield projects, our experienced team assists in implementing the right instrumentation systems and addresses complex site-specific challenges. We offer complete control system design, engineering, estimating, and scheduling, instrument design and specification, as well as procurement support.
