The Lim-controlled company has inked up to 20 chemical tankers at two Chinese yards in deals worth a total of around $360m.

Sources say Weihai Samjin Shipbuilding and Zhejiang Shenzhou Shipbuilding will each build four firm 11,000-dwt, IMO-2 newbuildings for delivery in 2017. Both deals include six options.

TradeWinds is told Ocean Tankers inked the orders at the end of 2015 to beat the deadline for nitrogen-oxides (NOx) Tier III-compliant engines.
