Navantia Completes Tropicalization of Norwegian F310 Frigates
HNoMS F-311 Roald Amundsen frigate

Spain’s Navantia shipyard has completed complex tropicalization work of the Roald Amundsen frigate (F-311) that Navantia designed and built for the Norwegian Navy between 2000 and 2011.

The warship is second of the Fridjof Nansen Class (F310).

These works, for which the contract was signed on July 2020, has improved the cooling capacity of the F311 frigate, which will allow it to navigate in conditions of much warmer ambient and water temperatures than the traditional operational scenarios of the Royal Norwegian Navy.

The modification, taken place from January to June 2021, has consisted on the replacement of the 3 refrigeration plants and the modification and increase of the air-cooling equipment in the engine rooms. The installation of this new equipment also has entailed the change of pipes, conduits, wiring, electrical panels, etc. that has made this program a great challenge both for the development of all the necessary engineering and for the execution of the works, both dismantling and installation, between Ferrol and Norway.

The F310 was developed with currently inoperative computer tools, so the decision has been made to develop the program already in Siemens NX in order to align it with the new Navantia digital platform. For this, 3D models of the necessary blocks were already migrated, and construction engineering work was developed in this tool.
