The S-81 Isaac Peral submarine has carried out mooring tests this week at the Navantia Cartagena facilities where it was built, which has meant putting its propeller in motion for the first time.

The test allows verifying the operation of the propulsion and the line of axes with the submarine moored in the dock and with autonomous power from its batteries.

For this, checks are carried out, both locally and remotely, from the Platform Integrated Control System (SICP) and also, both in normal operating mode and in emergency mode, verifying that the propulsion responds to all the orders sent and that all the markings are correct.

The process was carried out in the presence of inspectors from the Navy’s Engineering and Construction Department and with the participation of the submarine crew.

With this test, the S-81 has passed safety milestone number six, after the loading of batteries, the electrical power-up, the launching, the first start-up of the diesel generators and the first battery charge.

The S-81 is the first of the S-80 series of submarines of Spanish design and construction. The ship was floated last May, after a ceremony presided over by King Felipe VI.
