Beschreibung
Zusammenfassung:	A subsea arrangement including a main enclosure having a main enclosure volume; at least one main pressure compensator having a variable compensation volume in fluid communication with the main enclosure volume and configured to compensate volume variations of an internal fluid in the main enclosure volume; and at least one pressure sensor arranged to measure a pressure of the internal fluid. A method for detecting a malfunction of a subsea arrangement including a main enclosure having a main enclosure volume and at least one main pressure compensator is also provided.
