    Market assessment for suburban commuter trains
    description:
    Norske tog AS (�NT�) is a limited liability company established in 2017, as part of the reformation of the Norwegian railway sector. The company is fully owned by the Norwegian Ministry of Transport. The mandate of NT is to procure, own and manage passenger train vehicles in Norway, and thereby provide access to rolling stock by leasing out vehicles to passenger train traffic operators. The company�s rolling stock shall be offered on competition-neutral terms. NT has, with a few exceptions, the ownership of all passenger vehicles and locomotives in Norway. The company currently owns and manages nearly all Norwegian passenger trains operating on the Norwegian rail network, with a fleet currently amounting to over 250 trainsets. To ensure that we have up-to-date knowledge of the solutions available in the market, Norske tog is conducting a market survey through this request for information. This provides us with a solid foundation for assessing future needs and adaptations, and helps us to meet possible changes in capacity requirements and ensure flexibility in the train fleet. The Norwegian railway system faces increasing passenger volumes and evolving requirements for comfort, sustainability, and digitalization. At the same time, infrastructure investments and modernization programs create opportunities for improved performance and efficiency. Against this backdrop, Norske tog seeks to understand the market�s capabilities and innovative approaches for delivering local and regional trainsets tailored to Norwegian conditions.

    description:
    Oppdragsgiver for denne anskaffelsen er Havforskningsinstituttet. Havforskningsinstituttet har behov for et kamerabasert system som på en skånsom og effektiv måte kan ta høykvalitets bilder av fisk inne i trål, uten å ta fangsten om bord på fartøyet. Fisken, som blir fanget i trålen, blir tatt bilde av, og ved hjelp av disse bildene vil tilhørende datasystem (analyseprogramvare) kunne fastslå art, størrelse og antall fisk i trålen. Dette igjen vil være en del av Havforskningsinstituttets verktøy for blant annet fastsetting av riktige fiskekvoter og biologisk studier av fisken. Oppdragsgiver vil ikke inngå kontrakt med leverandør før tidligst 10 dager etter kunngjøringstidspunktet.

    description:
    Oppdragsgiver for denne anskaffelsen er Havforskningsinstituttet. Havforskningsinstituttet har behov for et kamerabasert system som på en skånsom og effektiv måte kan ta høykvalitets bilder av fisk inne i trål, uten å ta fangsten om bord på fartøyet. Fisken, som blir fanget i trålen, blir tatt bilde av, og ved hjelp av disse bildene vil tilhørende datasystem (analyseprogramvare) kunne fastslå art, størrelse og antall fisk i trålen. Dette igjen vil være en del av Havforskningsinstituttets verktøy for blant annet fastsetting av riktige fiskekvoter og biologisk studier av fisken. Oppdragsgiver vil ikke inngå kontrakt med leverandør før tidligst 10 dager etter kunngjøringstidspunktet.

How an AI agent should use this page

Ground rule: Navigate with HTML GET links to keep explanations and relationships. Use the page's JSON alternative only when concrete values must be extracted, compared or computed.

How to use the search_doffin lookup

  1. Replace the placeholders in the HTML GET template; remove optional parameters you do not need.
  2. Check types, units, limits and ID formats in the parameter table.
  3. Follow linked results to canonical pages before combining sources.

Misreading to avoid: An empty list means "no results for this lookup". An error message or unavailable source does not mean the data does not exist.

Source-specific next step

Go to the source page for other operations. Use the JSON template only after the HTML result shows that the parameters and source are correct.
