The Mid-Level Pipefitter is responsible for independently executing pipe fabrication and installation tasks aboard marine vessels. This role requires the ability to interpret technical drawings, fabricate piping systems, and install complex runs while maintaining compliance with maritime standards. The position supports shipboard mechanical systems including fuel, ballast, HVAC, fire suppression, and water systems.
Interpret piping isometrics, general arrangement (GA) drawings, and P&IDs to plan pipe layouts and installations.
Fabricate pipe spools using appropriate cutting, beveling, threading, and bending tools.
Install and align piping systems including valves, flanges, hangers, and supports in accordance with shipboard tolerances.
Perform tack welding or mechanical joint assembly (e.g., threaded, flanged, grooved, welded) as required.
Conduct hydrostatic and pneumatic pressure testing, ensuring compliance with testing procedures and documentation.
Work with QA/QC teams to verify proper alignment, cleanliness, and compliance with ABS, USCG, or NAVSEA standards.
Lead or mentor junior pipefitters in basic installation and fabrication techniques.
Coordinate with welders, engineers, and other trades for multi-system integration and system fit-up.
Follow and enforce safety procedures, including confined space entry, hot work protocols, and use of PPE.
Maintain job site cleanliness and ensure proper storage of materials and tools.
Diploma or certification in pipefitting, marine mechanical systems, or equivalent trade training.
3–5 years of marine or industrial pipefitting experience, preferably in shipbuilding, retrofits, or repair yards.
Proficiency in reading and interpreting shipboard pipe drawings and technical documents.
Skilled in using manual and powered pipe fabrication tools, such as threading machines, grinders, plasma cutters, and pipe benders.
Familiar with materials including copper-nickel, carbon steel, stainless steel, and PVC/CPVC.
Knowledge of marine piping codes and standards (ABS, DNV, NAVSEA, or similar).
Strong attention to detail and layout accuracy.
Experience working on tankers, naval ships, offshore platforms, or complex mechanical vessels.
Ability to work independently or in a team and communicate clearly with supervisors and engineers.
Willingness to work overtime, shifts, or onboard vessels under challenging conditions.
