Alfa Laval Aalborg boiler technology offers an easier path to LNG propulsion

Alfa Laval is not an engine maker, but is nonetheless playing a key role in the move towards LNG propulsion. Alfa Laval technologies and expertise – especially in the area of boilers – are enabling marine vessels to deal with boil-off gas (BOG), which is the critical step in making the shift to LNG. Alfa Laval’s dual-fuel boilers, Gas Combustion Unit (GCU) and services form a complete portfolio of solutions for BOG safety.

LNG is on the upswing, due to its role in reducing emissions and its relative economy compared to today’s low-sulphur fuels. “Customers are attracted to LNG propulsion for a variety of reasons, and it’s being considered for many vessel types besides LNG carriers,” says Markus Tauriainen, Manager Exhaust & Combustion System Sales at Alfa Laval.
 
In order to use LNG as fuel, vessels must be able to manage boil-off gas (BOG), the evaporated gas that can increase tank pressure. Alfa Laval is well known for BOG management on LNG carriers, where the Alfa Laval Gas Combustion Unit (GCU) safely burns BOG in compliance with the International code for Gas as Cargo (IGC). When it comes to using LNG for propulsion under the International code for Gas as Fuel (IGF), Alfa Laval is also managing BOG with dual-fuel Alfa Laval Aalborg boilers – and is tipping the balance in LNG’s favour for a far larger number of vessels.
