Wärtsilä secures spate of contracts for cargo handling and fuel gas supply systems in the LNG and ethane gas carrier segments.
Significant Reinforcement
Wärtsilä will supply Compact Reliq Single Boost reliquefaction systems for an even dozen LNG newbuildings under construction at Hudong-Zhonghua Shipbuilding, after securing an order for a further eight systems from the Chinese yard in late March. Each of the LNG newbuilds will have Wärtsilä Compact Reliq Single Booster (CRSB) reliquefaction systems to handle boil-off gas (BOG) from their LNG cargo. Wärtsilä’s BOG process is based on reversed nitrogen Brayton cycle refrigeration technology, using commercial-grade nitrogen to extract heat from the BOG. During this reliquefaction, the cryogenic cargo is maintained at the correct temperature and pressures. The CRSB system allows a portion of the BOG to be used as fuel for the ship’s engines, while the excess liquefied gas is returned to the main tanks to be sold as cargo.
In steam turbine and dual-fuel, diesel-electric propulsion applications, excess BOG not consumed by the engines was burned in a gas combustion unit. With the advent of more efficient two-stroke LNG dual-fuel engine technology, efficient reliquefaction systems are becoming increasingly important to maintain cargo tank pressures, reduce ship greenhouse gas emissions and optimize cargo carriage. “Reliquefaction systems are today becoming standard on all sizes of LNG carriers and our Compact Reliq system meets this need perfectly,” says Wärtsilä Gas Solutions head of midstream sales, Pål Steinnes.
Contracts Secured
In March and April, Wärtsilä reported securing contracts with South Korean and Chinese shipyards for cargo handling and integrated fuel gas supply systems for six very-large ethane carriers (VLECs) under construction for different shipowners. One of the contracts is with South Korea’s Hyundai Heavy Industries (HHI) for the supply of the cargo handling and integrated fuel gas supply systems for two VLECs for Japanese shipowner, IINO Lines. The Wärtsilä equipment for HHI is scheduled for delivery to the yard mid-2024.
“We have great respect for Wärtsilä as a provider of high-quality cargo handling and fuel gas supply systems, which are essential elements in the design of these ships. In today’s maritime market, close co-operation with trusted partners is increasingly important for ensuring projects are completed in the most efficient way possible,” said HHI vice president, Sangryul Kim.
