Vessels and pipelines
Purging, inerting, blanketing and cool down for LNG and LPG carriers, pipelines and plants. We clear out oxygen, moisture and hazardous vapours so your tanks and lines are safe to work on, then keep them protected with nitrogen until the job is done.
Our own crew does the work, alongside at the shipyard, out at anchorage or on site.

Vessels and plants
Bulk refills of industrial gases and refrigerants for vessels and plants. We top up your on-site storage tanks with liquid nitrogen, oxygen, argon and CO₂, recharge refrigerant systems, and refill bulk fire suppression systems.
The gas comes straight from our own ISO tanks, so your tanks stay full and your operation keeps running.
We run our own T75 and T50 ISO tanks, so there’s no wait to source or hire them.
Our engineers and technicians do the work themselves. No subcontractor to book.
Gas, tanks and crew are scheduled by one team, so nothing stalls at a handover.
