Expansion-minded Seacon Shipping is stepping up its presence in the tanker segment with more newbuildings.

The Hong Kong-listed Chinese company, which already has four MR product tankers under construction in China, is adding six more.

Sources said the deal is structured so that GHC Shipping, a joint venture between Seacon and Huanghai Shipbuilding, has placed the orders for the six 50,000-dwt newbuildings.
