Oslo-listed Stolt-Nielsen's tanker arm has inked its deal to buy the remaining five chemical tankers from Peter Georgiopoulos’ Chemical Transportation Group (CTG) and will use the vessels to replace others being retired from the company's fleet.

TradeWinds reported on Friday that Stolt-Nielsen was poised to strike on the the CTG quintet of 26,000-dwt tankers – the AVIC Dingheng Shipbuilding-constructed, 27,500-dwt CTG Magnesium and CTG Mercury (both built 2017), and 26,000-dwt CTG Argon, CTG Bismuth and CTG Cobalt (all built 2016).
