Angolan oil company Sonangol is understood to have sold one of its oldest suezmax tankers at a surprisingly low price.

The DSME-built 159,000-dwt Sonangol Kizomaba (built 2001) is reported to have been sold to an undisclosed Chinese buyer for $12m.

Price assessment service VesselsValue estimates the vessel is worth around $15.1m. Sonangol could not be reached for immediate comment.

The tanker has previously been employed in the Stena Sonangol suezmax pool, but TradeWinds understands this is no longer the case.
