Norway's Viken Shipping has concluded time-charter arrangements for all three handysize tankers that the company bought last month from German KG (limited partnership) outfits managed by Rigel Schiffahrts.

European shipbroking sources said the Bergen-based shipowner has chartered the 37,000-dwt Zambezi Star (built 2010) to Trafigura Beheer, while sisterships Inviken and Yukon Star (both built 2009) have been taken by trader Vitol.
