STX Dalian has recently inked additional order for 57,300-dwt supramax bulker from Helikon Shipping Enterprises with due delivery in the second quarter of 2014.
Now STX Dalian added up its total orderbook of the London-based company to five.
London broker Clarksons currently sets the price of a 57,000-dwt newbuilding at $25.5m but it is believed Helikon may have paid more.
Helikon originally booked two firm supramaxes and one option at STX Dalian in June 2010, later confirming the option and adding a fourth vessel.
At that time, the company also kept quiet on the price but the first pair was believed to have cost around $32m each and the second duo some $31m each.
The first is due out of the yard in November, to be followed by deliveries in January, April and June 2013.
