An agreement has been reached over ice trials with the shipowners that have ordered ice-breaking LNG carriers to serve Russia’s upcoming Yamal LNG project.

TradeWinds understands the deal will allow the 172,140-cbm sisterships to be ­delivered first to their long-term charterer, Yamal Trade, and then undertake ice trials at a later date.

A second dedicated ship for the soon-to-start-up project — the newbuilding Boris ­Vilkitsky, controlled by Dynagas, Sinotrans and China LNG Shipping — is now expected to deliver in December.
