Heidmar chief executive Ben Ognibene confirmed that Sigma has agreed to take the tankers when contacted by TradeWinds after word of the pact began to circulate in the market.

The four vessels are the 112,000-dwt Overseas Josefa Camejo and Overseas Fran (both built 2001), and Overseas Yellowstone and Overseas Yosemite (both built 2009). One unit is expected to enter Sigma this month and all by the end of July, Ognibene says.
