Results 2020: A unique arctic multipurpose small-draught rescue tugboat of the MPSV12 project "Beysug" was handed over to the customer



Results of 2020 at the on-line conference "Philosophy of ship design". On December 26, 2020 Rosmorrechflot received a small-draught arctic multifunctional rescue vessel - tugboat with a capacity of 5.2 MW, project MPSV12 "Beysug".
 
The series is being built by the Nevsky Shipyard.
 
Vessel project MPSV12 "Beysug" has a complex set of functions (patrolling, search and assistance to ships in distress, rescue, ship repair and diving operations, towing, OSR, rescue, evacuation and accommodation of people, fire extinguishing, TNGA with a depth of immersion up to 3000 m, delivery of goods and people), unique for its size (80-meter length) and arctic ice class ARC5 deadweight - with a draft of 4.50 m / 3.20 m it is 1936 tons / 440 tons.
 
From the speech of Professor Gennady Egorov at the on-line conference "Philosophy of ship design" (first day):
 
"The second point, which is interesting in the results of 2020, is that Rosmorrechflot continues to build complex multifunctional rescue vessels (MPSV12 project of the Marine Engineering Bureau - note by Gennady Yegorov) - the Nevsky Shipyard has now commissioned Beysug.
 
These are absolutely unique vessels that, indeed, for many years our colleagues (from the Marine Rescue Service - note by Gennady Yegorov) dreamed of receiving".

 
For your information. 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.
 
At the same time, draft restrictions, which are relevant for a significant part of the country's sea areas, play a fundamental role.
 
In addition, when the vessel is being rescued is shallow, it is desirable for vessel to have a minimum draft, then the vessel will be able to get closer to the object, and in some cases - bypass the damaged vessel beyond the edge of the deep-water fairway.
 
Marine Engineering Bureau carried out complex of investigations during MPSV12 prj. creation, because occurrence of complicated functions' combinations leads to mutual conflicting tendencies when hull forms, principal particulars and other prosperities of MSV are accepted. For example, propulsion complex should be satisfied to 6 operational modes requirements simultaneously:
 
• operation with service speed (about 70% from full speed) which is usual for patrolling in the set region and for normal voyages;
• full speed navigation at rescue/salvage operations (free-running high speed achievement that provides time reduction of approach to vessel in distress);
• towage of floating objects (providing of necessary pulling effort while towing operations in progress);
• providing of sufficient pulling effort for refloating emergency grounded vessel;
• ice navigation, including icebreaking operations (providing of required power capacity according to RMRS Rules due to accepted ice category of vessel for ice navigation vessels);
• dynamic positioning mode, necessary for extinguishing fires, performing underwater work, transferring cargo in ship to ship mode in waves and in wind.
