Wärtsilä Gas Solutions,
part of technology group Wärtsilä, will deliver the fuel supply system for two
new gas carriers that will operate with ammonia fuel. The ships are being built
at the Hyundai Mipo Dockyards (HMD) in Korea for ship owner EXMAR LPG, a joint venture between Exmar, a
multi-disciplinary maritime and offshore solutions provider, and Seapeak, one
of the largest independent owner-operators of liquefied natural gas vessels.
These EXMAR Medium size Gas Carriers new-buildings will be the first ever oceangoing
vessels to be propelled by dual-fuel engines capable of operating with ammonia,
these engines will be provided by WINGD.
The vessels are part of
a four ship series for which Wärtsilä has already been contracted to supply the
cargo handling and fuel supply systems. All four vessels were originally
ordered to operate on liquefied petroleum gas (LPG) as fuel. However, in
October EXMAR declared an option to change the fuel system and placed an order
with Wärtsilä to convert the fuel systems on two vessels to be able to operate
with ammonia. This order was booked by Wärtsilä in Q1, 2024.
“There is of course a
challenge to be considered when making a first-ever operational decision such
as this, requiring the latest technology. Wärtsilä has the experience and
technical competence to minimise this risk, which is why they were selected as
a key partner in this groundbreaking project,” said Carl-Antoine Saverys Chief
Executive Officer, EXMAR.
The full scope of Wärtsilä’s supply includes the
Liquid Ammonia Fuel Supply System along with process engineering and dynamic
simulation. The system is skid
mounted with low- and high-pressure fuel pumps, controls for fuel pressure and
temperature, and heat exchangers. Delivery to the yard is scheduled for 2025.
“We have had long and
close cooperation with both HMD and EXMAR, and are proud to be part of this
exciting project. When operating with ammonia fuel the CO2 emissions will be
reduced with about 90%. This is fully in
line with Wärtsilä’s strategy for enabling decarbonised shipping operations,
and is an endorsement of our capabilities to deliver future-proof systems
capable of handling a new generation of marine fuels,” commented Stein
Thoresen, Head of Sales Marine, Wärtsilä Gas Solutions.
