On 11.11.21 the keel of MPSV12 multifunctional small-draft Arctic rescue tugboat was laid at the Oka Shipyard.
FSD "State Customer Management of Maritime Transport Development Programs" of the Federal Agency of Maritime and River Transport of the Russian Federation is a Customer.
Vessel's project was designed by Marine Engineering Bureau.
In total, five MPSV12 multifunctional rescue tugboats (MSS) have been ordered. Nevsky shipbuilding and shiprepair plant has built three ships, one is being completed. Oka shipyard is building one ship.
MPSV12 multifunctional salvage tugboat (MSV) is a small-draught (working diapason is of 3.2-4.5 m) vessel with Arctic ice Arc 5 class, with inclined stem, with double-tier long forecastle, with ER located in middle, with diesel power system, with 2 controllable-pitch propellers, with 2 bow thrusters and single aft one.
MSV is intended the following operations:
• patrolling and emergency salvage duty at the navigation regions, fishing regions, oil and gas marine recovery regions in accordance with class notation;
• search and assistance for vessels in distress;
• salvage activity; ship-repairing; diving works at the depth till 60 m; underwater technical works including cutting & welding;
• towage of emergency vessels and objects to the place of refuge, also fulfillment of marine towage of vessels and floating objects, including ice towages;
• fire-extinguishing of burning oil on water surface, elimination of marine oil spills (LARN);
• search and investigation of potentially dangerous underwater objects;
• search, salvage, evacuation operations for people, rendering medical aid for people;
• give assistance in fire combating on floating objects and coastal ones accessible from seaside;
• delivery of general and liquid cargoes;
• transportation of personnel;
• control of remotely operated uninhabited deep-sea device of working class with 3000 m submergence depth.
The vessel was designed due to Russian Maritime Registry of Shipping class notation of KM  Arc 5  AUT2 FF2WS DYNPOS-2 Salvage ship.
Principal dimensions of the MPSV12 vessel are as follows:
length overall about - 79.85 m;
length between perpendiculars - 73.39 m;
breadth overall about - 17.36 m;
breadth (due DWL) - 16.80 m;
depth - 6.70 m;
draught DWL / max - 3.20 / 4.50 m.
Marine Engineering Bureau carried out complex of investigations during MPSV12 creation, because occurrence of complicated functions' combinations leads to mutual conflicting tendencies when hull forms, principal particulars and other prosperities of MSV are accepted.
As a result, unique characteristics were got for Arctic ARC5 ice class vessel of such dimension, as follows: deadweight is 1820 / 320 tons while draught is 4.50 / 3.20 m, autonomy is 30 days for fuel, water and provisions stores.
Keel of the MPSV12 head vessel (at the Oka shipyard) was laid on 11.11.2021.
