Holcim has delayed a decision on replacing one of two bulk carrier vessels, until it decides how to meet growth in cement demand.
The company will decide by mid-2009 about replacing the MV Westport, used to transport cement from its Westport plant to depots in ports around the country.
Holcim is considering designs for an 8000t vessel and a 12,000t vessel, expected to be operational in 2012.
Chartering a suitable ship would also be considered as an interim measure.
The company is investigating two long-term cement supply options – a new plant in either Westport or Weston, near Oamaru– and a medium-term option using its existing Westport plant.
