Dubai-based GMS has won U.S. government approval to scrap two sanctions-hit oil tankers it acquired, months after securing agreements to recycle four sanctions-hit container ships, the ship recycler told Reuters. The use ‌of so-called shadow fleet tankers has surged in recent years, with hundreds of tankers transporting Iranian or Russian oil with limited scrutiny, insurance or safety checks. 'DESTINED FOR RESPONSIBLE RECYCLING'GMS, which buys ships and recycles them at regulated yards, mainly in Asia, received U.S. licences on August 8 for two tankers, Yogesh Rehani, GMS' director of operations, said. "GMS transacted with the U.S. government, and no payment was made by GMS to the previous sanctioned owners. Earlier this year GMS told Reuters it had won U.S. approval to scrap four container ships subject to Iran-related sanctions.
