NDT Methods for Marine, Shipbuilding & Port Operations
Hull plate thickness measurement during dry-dock — detects corrosion wastage and pitting before classification society renewal survey
Weld inspection on hull structure, deck plates, and transverse framing per class-society rules (ABS, DNV, Bureau Veritas, Lloyd's Register)
New construction pipe weld examination and repair weld acceptance on high-pressure systems (steam, hydraulic) per ASME B31.1/31.3
Inspection in the splash zone and above-waterline areas on offshore structures and ship hulls — works through coatings and surface contamination
Classification society annual surveys of hull interior, void spaces, ballast tanks, and cargo holds; dry-dock bottom surveys

Typical Marine & Port Inspection Scope
Marine NDT concentrates on dry-dock surveys (every 2.5 years for Special Survey), where hull plating is UT-measured on a defined grid, all visible welds are VT examined, and any suspect areas receive MT or RT. Class-society renewal surveys require demonstrated NDT coverage meeting Rules. Newbuilding inspection covers 100% UT on hull welds and class-approved RT on piping and machinery welds.
Equipment & Asset Classes Inspected
Key Defect Concerns in Marine, Shipbuilding & Port Operations

Frequently Asked Questions — Marine, Shipbuilding & Port Operations NDT in Newark, NJ
Who authorizes NDT acceptance on a classed vessel?
The Classification Society surveyor (ABS, DNV, BV, LR, etc.) has the final authority on whether an NDT finding is acceptable under their Rules. In practice, the ship owner's NDT contractor performs the examination and presents data to the surveyor during the survey. For routine thickness gauging, approved firms can self-certify results against the class-defined allowable diminution tables. For weld repairs, the surveyor witnesses or accepts the NDT report before re-classing the work.
What is ACFM and why is it preferred in the splash zone?
Alternating Current Field Measurement (ACFM) is an electromagnetic technique that detects and sizes surface cracks through non-conductive coatings up to 10 mm thick without grinding. In the splash zone — the tidal region on a ship hull or offshore structure where marine growth, barnacles, and coating degradation make standard MT impractical — ACFM allows inspection without surface preparation. It measures both crack depth and length from the field perturbation pattern, providing ASME-compatible sizing data for fitness-for-service assessment.
When is NDT inspection demand highest for marine & port in Newark, NJ?
Newark, NJ's marine & port sector concentrates inspection demand around Refinery Spring/Fall — the period when most facilities schedule major outages, turnarounds, or planned maintenance campaigns. Booking NDT contractors 4–8 weeks ahead of your target window is strongly advisable; last-minute mobilization during peak periods typically costs 15–25% more and may mean accepting teams with less local experience. NDT Connect lets you post your scope early, collect quotes, and lock in a preferred contractor before the peak-demand compression begins.
