Stena Bulk has fixed two MR tankers managed by compatriot player Wisby Tankers for another six to 12 months, market sources said.

The Swedish operator was reported to have extended the charters for the 49,900-dwt Wisby Atlantic and Wisby Pacific (both built 2017) at $15,750 per day.

Brokers estimate the prevalent one-year rate for an eco MR vessel at somewhere between $14,500 and $14,750 per day.
