The opportunity

One vessel. Multiple cargoes. Greater utilisation.

Altair is developing multi-grade gas carriers designed around a simple commercial proposition: reduce the time and operational friction associated with changing between cargo grades.

Why multi-grade capability matters
VECS technology

Inflate. Displace. Reload. 24 hours.

A low-pressure system concept intended to make cargo-grade change faster, simpler and more repeatable.

Multi-grade platform

Designed around cargo optionality.

The commercial teaser identifies four core cargo families for the multi-grade concept.

LPG cargo
LPGEstablished gas shipping market with broad global demand.
Ammonia cargo
AmmoniaGrowing market with future clean-energy applications.
NGL cargo
NGLsFlexible feedstock and petrochemical-linked trade opportunities.
CO2 cargo
CO₂Emerging transport requirements across carbon-management chains.
From validation to scale

A technology pathway built toward commercial vessels.

The programme shown in the teaser moves from technology validation through commercial development and fleet build-out, with a preliminary final investment decision targeted for Q4 2027.
