Russia's Volga Shipping has begun a fleet renewal that will see 20 new cargoships added by 2030.

The Nizhny Novgorod-based owner is starting the order spree with a deal for four RSD71 river-sea bulkers at its own Oka Shipyard.

Two of these will be delivered in 2022 and two in 2023, the company said, without revealing a price.
