Navantia carried out the preliminary sea trials of the primary S-80 class submarine, Isaac Peral (S-81), within the Bay of Cartagena on Might 27, 2022. Navantia is constructing 4 of the submarines at its Cartagena shipyard for the Spanish Navy. Spanish state-owned shipbuilding firm Navantia introduced the event by means of a Twitter submit. The four-hour floor crusing marks the start of the Isaac Peral’s (S-81) sea trials. The submarine is a system of methods, and you will need to confirm the proper functioning of all methods and their integration. This primary cruise has confirmed the superb degree of integration and efficiency. The submarine will conduct the varied port and sea trials scheduled within the calendar, together with docking the submarine in the course of the summer time months.
In the course of the mooring trials, the operation of the submarine’s propulsive line shall be verified. That is carried out previous to the beginning of its sea ??trials.The boat accomplished start-up of its diesel engines in November 2021, marking a brand new security milestone. The beginning-up was carried out as a part of its port testing course of. The submarine is powered by three bio-ethanol engines, a 3,500kW major electrical engine, and a 300kW atmosphere-independent propulsion system. The S-80’s air-independent propulsion (AIP) system is predicated on a bioethanol-processor consisting of a response chamber and a number of other intermediate Coprox reactors. Offered by Hynergreen from Abengoa, the system transforms the bioethanol (BioEtOH) into excessive purity hydrogen. The output feeds a sequence of gas cells from UTC Energy firm.

The Isaac Peral (S-81), the primary unit within the sequence, was launched by King Felipe VI and his daughter, Princess Leonor, inheritor to the throne, on April 22, 2021 on the Cartagena shipyards, with plans to enter service in 2023, after initially being focused for 2011. The remaining three boats are slated to be delivered in 2025, 2027 and 2029. They’re oceanic submarines of medium tonnage with the capability to hold out lengthy period missions in eventualities removed from their base, performing with a minimal degree of indiscretion. They may have an built-in platform management system that permits operation with a lowered endowment and a excessive diploma of automation with distant management.
The S-80’s air-independent propulsion (AIP) system is predicated on a bioethanol-processor consisting of a response chamber and a number of other intermediate Coprox reactors. Offered by Hynergreen from Abengoa, the system transforms the bioethanol (BioEtOH) into excessive purity hydrogen. The output feeds a sequence of gas cells from UTC Energy firm. The Reformator is fed with bioethanol as gas and oxygen, producing hydrogen and carbon dioxide as subproducts. The produced hydrogen and extra oxygen is fed to the gas cells. The oxygen and gas movement charges are instantly decided by the demand for energy. The AIP energy within the S-80 submarine is no less than 300 kW (400 hp). A permanent-magnet electrical motor strikes a set propeller of a particular design, that doesn’t create cavitations at excessive pace.
