CDB Leasing has purchased four liquefied natural gas (LNG) carriers from entities linked to George Procopiou-backed Dynagas LNG Partners.

The Hong Kong-listed leasing unit of China Development Bank said it is paying up to $477.5m for the 149，700 cum vessels Clean Energy， Ob River and Amur River， built between 2007 and 2008， and the 2013-built 155，000 cum Arctic Aurora.

New York-listed Dynagas LNG Partners will lease back the vessels for a period between 60 and 120 months， maintaining its fleet of six LNG units.

The total amount of lease interest is expected to be around $130m， CDB Leasing said， adding that Dynagas LNG Partners has the option to purchase back the vessels for $95.5m when the leases expire.

CDB Leasing has done several LNG transactions in the past， taking three of Procopiou’s 200，000 cum LNG newbuilds， a number of units from Peter Livanos-controlled GasLog， and most recently， two ships from Awilco LNG.
