S-81 “Isaac Peral”, the first submarine of the S-80 series built by Navantia for the Spanish Navy, has successfully passed the safety milestone of starting its diesel engines, which is part of its port testing.
The start-up was carried out successfully on Friday, November 12 at the Armament Dock of the Cartagena shipyard. That same day, the start-up of the diesel engines of the S-71 “Galerna” was also successfully carried out, which is in port tests as part of the work to extend its life cycle.
The S-80 program follows a regulated Systems Engineering process, by means of which it is necessary to pass a series of technical reviews or quality doors in which it must be demonstrated that the submarine is ripe to move on to the next phase. Diesel engine start-up is the fourth safety milestone, after power-up, the shipment of batteries to the ship and launching.
The S-80 class submarines have diesel engines with diesel alternator rectifiers (DAR) that allow the charging of their batteries or that can directly supply power to the main electric motor. The diesels are manufactured by the Navantia Cartagena Motors factory, under an MTU license.
In the coming months, the S-81 will undergo the first battery charges with the DAR and the test on moorings, the first moment in which the operation of the submarine’s propulsive line is verified in a tangible way, prior to the start of the sea trials.
The S-71 advances in the extension of its life cycle
In parallel with the construction of the S-80 series, the Navantia shipyard in Cartagena is carrying out the extension of the life cycle of the S-71,’Galerna’, which has undergone at the beginning of the official start-up and start-up tests. operation of diesel engines in the presence of Spanish Navy inspectors, once all the necessary verifications and checks have been carried out on both the auxiliary services of said engines and their safety.
