Job description

Job Purpose

To lead the design and engineering of shipboard piping systems for Naval and Commercial shipbuilding projects, from concept design through detailed engineering and production support. The role involves providing technical leadership in piping system design and integration, ensuring compliance with Indian Navy specifications, classification society rules and international standards, while driving design quality, project execution, team development and engineering process improvements.

Key Responsibilities

• Lead the design and development of shipboard piping systems for Naval and Commercial shipbuilding projects, covering Bilge, Ballast, Fuel Oil, Lubricating Oil, Fire Main, Cooling Water, Hydraulic and Compressed Air systems.
• Oversee concept, basic and detailed engineering, ensuring effective system design, integration and compliance with project requirements.
• Prepare and review P&IDs, piping layouts, 3D models, equipment arrangements, isometric drawings, fabrication drawings and associated technical documentation.
• Drive piping routing, equipment integration, clash detection and space management, ensuring design feasibility and production requirements are addressed.
• Review engineering calculations relating to flow, pressure drop, pipe sizing and overall system performance.
• Ensure compliance with Indian Navy specifications (SOTR), Naval Engineering Standards, applicable Classification Society Rules, JMO, SOLAS and other relevant statutory and project requirements.
• Lead design reviews, technical discussions and approval processes with Indian Navy representatives, customers, shipyards and classification societies.
• Review vendor drawings, technical specifications, equipment selection and engineering submissions for shipboard piping systems.
• Coordinate with Structural, Mechanical, Electrical, HVAC, Outfit and Production teams to ensure effective multidisciplinary design integration.
• Provide technical guidance and resolve engineering issues arising during design, construction, installation, commissioning and sea trials.
• Manage engineering changes, design modifications and configuration control to ensure consistency across approved design documents and production deliverables.
• Plan and monitor engineering activities, resource allocation, project schedules and timely completion of design deliverables.
• Lead, guide and mentor a team of piping designers and engineers, ensuring capability development, productivity and quality of engineering outputs.
• Establish design quality standards, review mechanisms and technical checks to minimise design errors, rework and production-related issues.
• Identify and drive process improvements through digitalisation, automation and adoption of AI-enabled engineering tools to improve design productivity and accuracy.
• Shipboard Piping System Design and Engineering.
• Piping System Integration for Naval and Commercial Ships.
• P&ID Development and Review.
• 3D Piping Design, Routing, Clash Detection and Space Management.
• Piping Engineering Calculations – Flow, Pressure Drop and Pipe Sizing.
• Equipment Integration, Material Specifications and Technical Documentation.
• Knowledge of Indian Navy Specifications (SOTR), Naval Engineering Standards, Classification Rules, JMO and SOLAS.
• Design Reviews, Customer Interface and Technical Approval Management.
• Cross-functional Coordination with Production and Other Engineering Disciplines.
• Project Planning, Scheduling and Engineering Deliverable Management.
• Design Quality Assurance and Configuration Management.
• Team Leadership, Mentoring and Capability Development.
• Digitalisation, Automation and AI-enabled Engineering Process Improvement.
• Familiarity with digital engineering, 3D model-based design, design automation and emerging AI applications in engineering.
