STX Norway Offshore has secured an order from JSC Circle Marine Invest worth over $70m.
The contract for two icebreaking tugs takes STX’s order backlog with the Kazakhstani shipowner to five.
STX will build the tugs at its Braila shipyard for delivery in 2011, say president Roy Reite.
Both of the vessels, which have a combined price tag of NOK 450m ($71.31m), will be operated by JSC’s Caspian Offshore Construction in the Caspian Sea.
