LLC MurmanStroy

About company

MurmanStroy, a part of Barents company group, is a prominent company of the fishing industry of the Murmansk oblast and the entire North-West of Russia.

  • The company operates a certified multi-building cold store with its own pier at the Kola bay.
  • It is a member of an investment quotas program for fishing companies and is completing the construction of a fish-processing complex, Arktika, with a daily capacity of 25 tons of finished product (fillet and minced cod, and haddock). The complex is designed to process (freeze) production residue.

MurmanStroy was selected as a technical assistance recipient under the component Conversion of the selected enterprises to ozone- and climate-safe substances and technologies of Phase 2 of the Project “Phase-out of Fluorinated Greenhouse Gases and Ozone-Depleting Substances at Fish and Seafood Processing Enterprises of the Murmansk Oblast (Arctic Zone of the Russian Federation).”

Tasks to be solved

A single-stage refrigeration system is used to service the needs of the cold store, consisting of:

  • a single-frame packaged compressor of four screw compressors,
  • an air condenser,
  • a circulation receiver,
  • a refrigerant pump,
  • air-coolers.

The system is charged with R-22, an ozone-depleting substance (ODS) (ODP 0.05, GWP 1810).

As of the beginning of 2020 and 2021, the refrigerant charge was 3 tons, and 0.41 tons were used to re-charge the system due to leakages.

Conversion through the Project will ensure direct phase-out of 0.165 tons of ozone-depleting potential (ODP) and 5,430 tons of CO2-equivalent, and within 5 years after conversion ensure indirect phase-out of 0.113 ODP tons and 3,715 tons of CO2-equivalent.

Planned activities

Through the conversion, the existing refrigeration system will be replaced by a cascade secondary refrigeration system consisting of two cooling circuits connected in series. A high-temperature circuit is charged with a natural refrigerant R-717 (ammonia) that cools a low-temperature circuit with a secondary refrigerant R-744 (carbon dioxide) pumped to consumers.

The conversion is financed by the grant of the Arctic Council Project Support Instrument and co-financed by a technical assistance recipient.

Grant-funded works, supplies, and services:

  • developing design estimates for conversion of the refrigeration equipment to ozone- and climate-safe substances and technologies;
  • purchasing, manufacturing, and supplying primary and extra equipment;
  • installing, commissioning, and performing other works according to the design specifications and estimates;
  • purchasing, installing and commissioning safety equipment, and adopting safety measures;
  • obtaining permits;
  • recovering ODS and F-gases for destruction or recycling;
  • dismantling and disposing of old equipment;
  • improving energy efficiency;
  • training personnel in the environmental legislation and operation of environmentally safe refrigeration equipment in accordance with the Russian legislation.

The contractor will be selected through bidding.

Co-financed works:

  • equipping a new production complex with a CO2 (R-744) refrigeration system;
  • overhauling a building and heat insulation constructions of the cold store to be converted;
  • installing power lines and constructing electric substations to connect a complex and a cold store to the urban electric network;
  • financial losses due to suspension of production.
