In our fourth tech talk in this series, Rune Knott, General Manager, Sales & Marketing, talks to four industry experts about gas solutions for LNG carriers. Lasse Bergerud-Wichstrøm, Sales Manager for re-liquefaction solutions at Wärtsilä, Terje Steingrimsen, Sales Manager for inert gas systems at Wärtsilä, Karsten Kroschel, Head of Sales Marine Systems at SAACKE, and Saman Siahpoush, Business Development Manager, Wärtsilä Gas Solutions Services, share the benefits of Wärtsilä’s Compact Reliq™ reliquefaction system, inert gas systems, boiler system and gas combustion units, and gas solutions services.
Wärtsilä is a leading designer, developer and supplier of energy-efficient LNG boil-off gas (BOG) re-liquefaction plants, all designed to be efficient, reliable, safe, robust and flexible. “Compact Reliq is one of our reliquefaction solutions,” explains Bergerud-Wichstrøm. “When vessels are travelling, they generate BOG due to the heat ingress in the tanks. This compressed gas is de-superheated and reliquefied in the cryogenic heat exchanger, allowing proper BOG handling during all ship operations. The reliquefied gas is then returned to the bottom of the cargo tanks using our reversed nitrogen Brayton cycle refrigeration technology. Compact Reliq is next-generation technology that works well in all operating scenarios and, in our opinion, gives the best available flexibility.”
