| Use advice for data set | This EPD covers modules A1–A5 and C1–C4, with module D included. The use phase (B1–B7) is not included due to lack of relevant emissions or impacts during normal operation. Manufacturing data reflects production at Nøsted & AS in Mandal, Norway, including heat treatment, galvanization, testing and packaging. |
| Technical purpose of product or process | The product is an alloy steel chain intended for demanding marine, aquaculture and general mooring applications. The chain is manufactured at Nøsted & AS in Mandal, Norway, using high-quality West European steel, heat-treated for increased toughness and proof-load tested link by link. The chain is available in two corrosion-protection variants: • Fram Aqua (thermo-galvanized): A thermochemical zinc diffusion process that forms a smooth, hard and highly durable corrosion-resistant layer with excellent fatigue performance. Fram Aqua chains are certified in accordance with NS 9415 for use in floating aquaculture installations. • Hot-dip galvanized (HDG): A traditional zinc coating applied by immersion in molten zinc, in accordance with NS 9419. Used for fishery, trawl operations and general industrial applications. The product family covers short-link, mid-link and long-link chain geometries, all produced according to the same manufacturing and heat-treatment principles. The chains are fully compatible with FRAM Aqua mooring components such as shackles, master links and mooring plates. Corrosion protection is applied after controlled heat treatment. For Fram Aqua thermo-galvanized chains, zinc is diffused into the steel surface through a thermochemical process without acidic pickling, eliminating the risk of hydrogen embrittlement. HDG chains are coated by immersion in molten zinc in accordance with NS 9419. The product family includes short-link, mid-link and long-link chain geometries, all produced using the same alloy steel, heat-treatment process and mechanical testing requirements. All chain links undergo 100% proof-load testing. Additional mechanical and metallurgical testing is performed to ensure strength, toughness and long-term corrosion resistance in marine environments. |
| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Primary manufacturing data is sourced directly from the Nøsted & AS Mandal plant. Secondary data for raw materials, energy, and transport is sourced from recognized LCI databases in accordance with EN 15804+A2. Data quality is considered high. Allocation: The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |
