Wärtsilä supplies systems for ammonia carriers

The 88,000m³ capacity vessels have been ordered by a Japanese ship owner and the order was booked in Q2 2025.

“We have good experience with Wärtsilä’s cargo handling systems,” said Mr Lee, leader of basic design team, Hanwha Ocean Co.

“Their support and quick reaction to our needs have always been much appreciated, and their systems are perfectly designed for these two VLACs.”

VLACs are very large gas carriers specifically designed to carry full cargoes of ammonia. Since ammonia has a high specific gravity, VLAC cargo tanks and hulls need to be reinforced and the vessels will have a deeper draught when fully loaded.

“Enabling decarbonised shipping operations is at the core of our strategy,” said Patrick Ha, sales manager, Wärtsilä Gas Solutions.

“This contract is an additional proof point for continuous successful strategy implementation, while reinforcing our strong partnership with Hanwha”.

The Wärtsilä equipment is scheduled for delivery to the yard commencing in Q4 2025.
