Built by Mariners. Engineered for LNG.

About Company

Built by Mariners, Driven by Decarbonization

Unnic Bunkering Services Private Limited was created with one focus: getting alternative fuels safely, accountably, and efficiently into vessel tanks across Indian ports.

We sit within the Unnic group, where our engineering team brings years of hands-on experience with cryogenic systems, low-flashpoint fuels, and toxic fluid safety. Our team has sailed. We have stood on decks, signed Bunker Delivery Notes, and managed transfers firsthand.

That experience shapes our approach. Bunkering alternative fuels, whether handling -162°C LNG, low-flame-visibility methanol, or toxic Ammonia, is a high-precision marine engineering task. It requires thermal control, accurate measurement, and an absolute safety envelope.

What we do

Built In-House. Delivered On-Schedule.

A manifold mismatch is one of the top causes of bunkering delays. We solve this by custom-fabricating our own transfer pipework and skids in-house to match your vessel’s exact manifold geometry. Adapting to your setup is a quick engineering job with guaranteed lead times.

Our complete scope covers:

  • Multi-Fuel Operations: Truck-to-Ship (TTS) delivery for LNG, bio-methanol, and green ammonia at major Indian ports.
  • Hardware Supply: Certified transfer hoses (DN65 to DN150), dry-disconnect couplings, breakaway units, and metering skids.
  • Consultancy & Oversight: Ship-shore compatibility studies, HAZID/HAZOP reviews, SIMOPS protocols, and attending superintendents.
WHAT WE BUILD

Custom Pipework Built to Fit

We manufacture key transfer components designed for extreme cryogenic cold and reactive chemical environments:

  • Cryogenic & Chemical Saddles
  • Manifold Distance Pieces
  • Custom Spool Pieces & Reducers
  • Class-Certified Marine Flanges

     

Key Performance Stats:

  • 100 to 120 m³/h: Fuel transfer rate to vessel
  • 4 Tankers: Continuous hot-swap delivery capacity
  • 75+ Years: Combined seagoing & gas operations experience
  • DN65 to DN150: Certified hose and piping range

Our commitment to quality

We are pursuing ISO 9001 (quality), ISO 14001 (environment) and ISO 45001 (occupational health and safety) certification.
