Barges

Tank barge fleet outfitting

A complete access package for liquid-cargo tank barges: raised watertight hatches, ullage hatches, expansion trunks and flame screens, specified from one catalog.

Vessel type: Liquid-cargo tank barges
Region: U.S. inland waterways
Standards: ABS PDA 25-0092892-2 · ASTM A36 · ASTM A27
Products: 8

The challenge

Tank barges need dozens of openings per hull: wing-tank and rake access, cargo-tank vents and inspection ports where crews measure or verify cargo. Every opening must stay watertight through years of weather, product contact and rough handling, and spare parts must match without re-machining.

What we supplied

Raised 4-dog oval hatches (UMC-464-5, 18" × 24") for wing tanks and the rake compartment, with ABS PDA 25-0092892-2.
Hatch + ullage combinations (UMC-464-5 / 144) so the ullage serves as a vent or inspection port without opening the main cover.
Expansion trunks (UMC-470) and expansion domes (UMC-450) with a stainless upper coaming ring for corrosion resistance at the seal.
Flame screens and nitrile gaskets ordered as matched spares.

The result

One supplier, one part-number system and documented ABS design assessment for the hatch family — simpler procurement for the shipyard and faster spare-parts turnaround for the operator.
