Clearlake Shipping, the ship chartering arm of commodity trader Gunvor, is being linked to more long-term charters of modern tanker tonnage.

The company, one of the largest tanker charterers in the world, is reported by brokers to have fixed two suezmax newbuildings on order in China from Greece’s Polembros Shipping.

The Spiros Polemis-controlled shipowner is said to have fixed the two unnamed ships to Clearlake for periods of five years each upon delivery at a rate of $36,000 per day.
