CASE STUDY BACKGROUND

With diving gas exceeding $70 per m3 and some dive support vessels (DSV) using over $1million of it per year, the justification for optimising gas reclaim performance is more important than ever. Escalating helium prices are being driven by the scarcity of this finite element, supply chain constraints and global helium demand.

In 2022, some diving gas suppliers increased their prices by as much as 235% and markets expect the helium squeeze to continue well into 2025.

This case study explains how the salvage of the secret cargo of a World War II British Royal Navy cruiser was pivotal in the introduction of gas reclaim, without which today’s commercial saturation diving would not be commercially practical.
