China Development Bank Financial Leasing (CDB Leasing) continues to add LNG tonnage to its fleet following a sale-and-leaseback deal with Dynagas LNG Partners.

The US-listed, George Procopiou-backed shipowner has sold four vessels to the Hong Kong-listed lessor for a total of $477.5m, according to a regulatory filing.

The ships are the 149,700-cbm Clean Energy and Ob River (both built 2007), Amur River (built 2008) and the 155,000-cbm Arctic Aurora (built 2013).
