A marine industry organization undertaking an exhaust gas scrubber system program required integrated engineering support from process design through fabrication readiness. The project involved detailed P&ID development, 3D equipment and piping modeling, structural lifting analysis, and CFD-based performance validation to optimize system effectiveness in demanding marine environments. The engagement was delivered with a strong emphasis on technical accuracy, regulatory compliance, and timely execution.

The scope included:

• P&ID Detailing for the exhaust scrubber system
• Material Selection for marine-grade components
• 3D CAD layout of piping on the scrubber assembly
• Structural Support & Lifting Analysis for handling and installation
• CFD flow analysis (velocity streamline evaluation)
• Fabrication (FAB) Process Support documentation

Challenge:

Marine Operating Environment

• Designing scrubber and piping systems to withstand vibration, corrosion and load conditions specific to sea vessel operation
• Selecting materials suited to sustained marine exposure

Space & Layout Constraints

• Fitting scrubber piping and support structures within constrained vessel deck/engine room layouts
• Coordinating piping routing around existing vessel systems

Flow Performance Validation

• Ensuring scrubber exhaust flow met performance requirements without excessive turbulence or pressure loss
• Validating design through simulation rather than physical prototyping alone

Fabrication & Lifting Safety

• Designing structures capable of safe lifting and handling during fabrication and installation
• Producing fabrication qualification documentation to guide manufacturing teams
