Muscat-based Oman Shipping has reportedly locked another ship into a period charter.
European brokers say the 110,000-dwt LR2 tanker Haima (built 2009) has been fixed for up to a year to PDS.
The tanker was taken for six firm months at $17,750 per day with an option for six more months at $19,750 per day.
In August last year the tanker completed a one-year charter to Glencore International at $15,250 per day.
