1. A Remotely Operated Vehicle (ROV) subsea robot for detecting a breakdown in production systems, the ROV subsea robot comprising:
a propulsion system (14),
at least one battery (15),
a set of cameras (16),
a body (17) that enables the insertion of various auxiliary components,
a remote connection (18),
a connection with the RCV vessel (19),
a Naturally Occurring Radioactive Material (NORM)-detection system (11), and
an ultrasound emission system (12),
wherein the NORM-detection system (11) comprises a sodium iodide Nal crystal scintillator detector, coated with magnesium oxide, with an aluminum housing, in which the array is duly encapsulated to be used at depths deeper than 1500 meters.
