Mitsui Engineering & Shipbuilding appears to have won an order for 56,000-dwt bulker from Ambi Shipping.
The newbuilding costs $26.6m with delivery in the first half of 2015.
Mitsui had delivered 55,600-dwt bulker M.V. Alam Manis to MBC in March 2007, and before that it completed delivery of one 46,600-dwt newbuilding for the shipowner.
MBC is an amicable shipowner to Japanese shipyards, which placed orders at Japan for about 90% of its fleet currently in operation.
Ambi Shipping is using internal funds to pay for the vessel in five installments.
Ambi is a joint venture between MBC, through its wholly-owned subsidiary, Lightwell Shipping and Japanese trading house Mitsui & Co with the share equity set at 70% and 30% respectively.
