Wärtsilä gas handling systems for eleven gas carriers

The contract for these systems for six new type Very Large Gas Carriers (VLGCs), two conventional VLGCs, and three Medium Gas Carriers (MGCs), represents one of the largest single deals for gas cargo handling solutions ever received by the company.

Timo Koponen, vice president, flow and gas solutions, Wärtsilä, said: “The efficiency and reliability of the Wärtsilä Gas Cargo Handling Systems have made us a recognised market leader in supplying systems for gas carrier vessels. During recent years we have delivered numerous systems for different sizes and types of these ships, and these latest contracts provide further evidence of our leading technologies in this field.”

Three Wärtsilä Gas Reliquefaction Plants will also be installed in each vessel. The plants have a higher refrigeration capacity and better efficiency than earlier versions delivered to VLGC`s and will be capable of handling propane with a high ethane content of 8.5% mol.

In addition, a Wärtsilä Purge Gas Recovery Unit will also be supplied with each complete system. These will collect the hydrocarbons in the purge gas during the gassing up of the cargo tanks, resulting in a significant reduction in hydrocarbon emissions.

The contract also includes cargo pumps, inert gas plants, and an equipment package comprising compressors, heat exchangers and control systems.

Deliveries are scheduled for the period between late 2016 and early 2018.
