 Like the platform supply vessel ordered in April, the standby vessels would be chartered to Sakhalin Energy Investment Company (SEIC) and used in the Sakhalin-2 field for stand-by, rescue and oil spill response duties.The vessels "Stepan Makarov", "Fedor Ushakov", and "Yevgeny Primakov" (initially "Mikhail Lazarev") would have accommodation for 98 persons on board and be capable of operating independently in ice.The keel of the first standby vessel was laid on 4 February 2016 alongside the previously-ordered platform supply vessel.
