Expanding UK-based shipowner Purus Marine could take its spending on new LPG carriers to above $410m.

The company confirmed it has ordered four 45,000-cbm midsize vessels at Hyundai Mipo Dockyard (HMD) in South Korea for delivery in 2025 and 2026.

The ships will be able to use ammonia as a fuel and fitted with shaft generators and scrubbers.
