Frontline got an offer it could not refuse to slip another one of its aframax tankers into clean product trades.

On the company's second-quarter earnings call on Thursday, chief executive Lars Barstad said a charterer was willing for one of its ships to have its tanks cleaned, then take it on a voyage carrying products right away.

"In this case, we found an opportunity to actually wash the tanks at a reasonable cost and have a following voyage lined up already," Barstad said.
