Beschreibung
Zusammenfassung:	A large diameter subsea gravity separator for ultra deep water conditions of 2 000 to more than 4 000 m comprises a vessel (1) having a shell (13) which defines a cylindrical tubular portion (3) and closure portions (5) at axially both ends of the tubular portion (3). The shell (13) is a sandwich shell which is dimensioned to provide for a predetermined collapse resistance of at least 30 MPa and comprises an inner steel layer (15), an outer steel layer (17) and a concrete layer (19) completely filling the space between the inner steel layer (15) and the outer steel layer (17).
