Four crew seized from an RK8 Offshore anchor-handler off Congo in October have been released.

The company confirmed the seafarers from the 2,300-dwt Ark Tze (built 2009) are safe and in good spirits.

The men were taken on 29 October, the same day eight crew were kidnapped from a Norbulk-managed bunker tanker, the 9,600-dwt Anuket Amber (built 2008), in the same area.
