South Korean shipyard Hyundai Samho Heavy Industries (HSHI) is constructing the three new ships for Knutsen OAS Shipping.

This Wärtsilä’s tech order represents options taken following an earlier order for two Knutsen’s newbuild carriers.

Wärtsilä launched Compact Reliq in 2020. It features a compact design for easy installation and maintenance on all sizes of carrier vessels.

The solution is based on the reversed nitrogen Brayton cycle refrigeration technology. It reliquefies the boil-off gas (BOG) and keeps the cargo cool under all operating conditions. Besides, a portion of the BOG can serve as fuel for the ship’s engines. You can sell the excess as part of the LNG cargo.
