National Marine Dredging

SCAC NMDC · Abu Dhabi, UAE · founded 1976 · Independent / non-aligned

National Marine Dredging (legal entity National Marine Dredging Co.) is a global mainline operator headquartered in Abu Dhabi, UAE. Founded in 1976, the line has spent 50 years building out its container service network and today operates a fleet of 80 vessels under the SCAC code NMDC. National Marine Dredging operates as a non-vessel-operating common carrier (NVOCC) and does not own its own container ships, placing the carrier among the recognised operators on its core trade lanes. The company holds intermodal equipment under 3 registered ISO 6346 owner prefixes, which appear on every box it owns or long-term leases.

National Marine Dredging is most active on the following corridors: Dredging, Marine Construction. The line operates on a standalone basis and does not share vessel slots with other ocean carriers under a formal global alliance. Direct customer contact is available via +971 2 513 0000 or the carrier's web portal at nmdc.com.

National Marine Dredging container prefixes

Every intermodal container carries an ISO 6346 owner code — three letters identifying the owner, plus a single category letter (almost always U for freight containers). These four-letter prefixes are the fastest way to identify which carrier controls a given box. National Marine Dredging has the following registered prefixes recorded in the BIC database. If a container in your possession begins with any of these codes, the box is owned by or leased on long term to National Marine Dredging.

To track a container under one of these prefixes, contact the carrier directly using the bill-of-lading number or container number. Most ocean carriers expose a public tracking endpoint on their website that accepts either format. National Marine Dredging publishes its tracking page under the main nmdc.com domain.

How to track a National Marine Dredging container

Tracking a National Marine Dredging container starts with confirming the prefix. Look at the container's left-hand corner casting plate or the painted code on the door — the four-letter ISO 6346 owner code (e.g. NMDU) is followed by six numeric digits and a single check digit. If the prefix matches one in the list above, the box is on a National Marine Dredging bill of lading. Visit nmdc.com, navigate to the carrier's tracking or "track and trace" portal, and paste the full container number. The portal will return current vessel position, the next scheduled port call, the estimated time of arrival (ETA) and the most recent equipment events such as gate-in, loaded, discharged and gate-out.

If the carrier portal does not return a result, the most likely causes are: the container has not yet been gate-in at the origin terminal, the bill of lading number is in a different format (check whether the system expects an MBL versus an HBL), or the box is moving on a partner alliance vessel rather than a National Marine Dredging hull. In the last case, the prefix still resolves to National Marine Dredging as equipment owner but the schedule data lives with the operating carrier. National Marine Dredging's customer service can normally cross-reference the booking and route you to the correct alliance partner. Reach the carrier on +971 2 513 0000 during European business hours.
