New York listed Teekay LNG has bought a 30% interest in two of the ships and one fifth of the other two, a statement said.
It comes just a few days after TradeWinds revealed Teekay was buying a slice of the quartet from BG Group.
Teekay says CETS, a division of China National Offshore Oil Corporation, and China LNG Shipping are the other investors in two of the vessels.
