Marine fuel supply company Onsys Energy plans to buy four new vessels following on from a recent order for two vessels.

The four vessels will be 9,000dwt chemical tankers worth $23m (RM81.7m) each, which Onsys Energy has ordered from the Titan Quanzhou Shipyard, China.

The Malaysian company said it expects the vessels to be delivered by March 2010.

The company recently signed a financing deal worth RM50m with Asian Finance Bank for the purchase of two 7,000dwt marine fuel oil tankers.
