The new alliance of pools operator Heidmar and manager Signal Maritime has suffered the first of predicted tanker defections with the loss of three International Seaways aframaxes.

The departures had been mooted by tanker market sources and were confirmed on Wednesday by Concord Maritime chief executive Ben Ognibene, whose Dakota Tankers aframax pool will be taking in the tonnage.

New York-based International Seaways is moving the 112,792-dwt Seaways Redwood (built 2013), 112,989-dwt Seaways Yellowstone and 112,905-dwt Seaways Yosemite (both built 2009).
