SFL Corporation has announced the lease to Denmark's A.P. Møller-Mærsk of four 8,700 TEU container ships for duration of five years, an agreement that will increase the SFL's rental portfolio of approximately $240 million. The ships are already operated by the same Danish group as part of rental contracts that will expire next year. With the new agreement SFL Corporation has undertaken to carry out investments worth a total of about 20 million dollars in the four container holders which include, among other things, the increase in their load capacity to 9,500 TEUs.
