A method for protection of compressor modules against undesirable influx of contaminated gas, comprising a pressure housing (3) which by means of one of more sealing elements (4) is generally divided into a first compartment (8) equipped with a compressor (2) and a second compartment (7) equipped with a gas-filled motor (1), the compressor and the motor being drivably connected to each other by at least one shaft (9), is distinguished by protecting the second compartment (7) with motor (1) against direct influx of contaminated gas from the first compartment (8) with compressor (2) by means of compressed gas that is supplied from a withdrawal point (13) at the first or intermediate stage of the compressor, or from the compressor outlet (16), and by introducing the compressed gas directly into the seal (4) or in between two or more seals so as to flow through the at least one seal (4) back to the first compartment (8). The invention also relates to an apparatus for use in connection with the method.

1. A method for protection of compressor modules against undesirable influx of contaminated gas, comprising a pressure housing (3) which by means of one of more sealing elements (4) is generally divided into a first compartment (8) equipped with a compressor (2) and a second compartment (7) equipped with a gas-filled motor (1), the compressor and the motor being drivably connected to each other by at least one shaft (9), characterised in protecting the second compartment (7) with motor (1) against direct influx of contaminated gas from the first compartment (8) with compressor (2) by means of compressed gas that is supplied from a withdrawal point (13) at the first or intermediate stage of the compressor, or from the compressor outlet (16), and introducing the compressed gas directly into the seal (4) or in between two or more seals so as to flow through the at least one seal (4) back to the first compartment (8) with compressor (2). 2. A method according to claim 1, characterised in introducing the compressed gas from the compressor (2) into the seal (4) or in between two or more seals via an external pipeline (14) or an internal bore. 3. A method according to claim 2, characterised in installing the compressor module under or above water, on platforms or onshore. 4. A method according to claim 2, characterised in introducing the compressed gas from the compressor (2) into the seal (4) or in between two or more seals via a gas treatment unit (17) connected to the external pipeline (14) or the internal bore. 5. A method according to claim 2, characterised in cooling the second compartment (7) with motor (1) by use of a closed cooling circuit equipped with an external motor cooler (12). 6. A method according to claim 2, characterised in supporting the at least one shaft (9) by magnetic bearings (11). 7. A method according to claim 1, characterised in installing the compressor module under or above water, on platforms or onshore. 8. A method according to claim 7, characterised in introducing the compressed gas from the compressor (2) into the seal (4) or in between two or more seals via a gas treatment unit (17) connected to the external pipeline (14) or the internal bore. 9. A method according to claim 7, characterised in cooling the second compartment (7) with motor (1) by use of a closed cooling circuit equipped with an external motor cooler (12). 10. A method according to claim 7, characterised in supporting the at least one shaft (9) by magnetic bearings (11). 11. A method according to claim 1, characterised in introducing the compressed gas from the compressor (2) into the seal (4) or in between two or more seals via a gas treatment unit (17) connected to the external pipeline (14) or the internal bore. 12. A method according to claim 11, characterised in cooling the second compartment (7) with motor (1) by use of a closed cooling circuit equipped with an external motor cooler (12). 13. A method according to claim 1, characterised in cooling the second compartment (7) with motor (1) by use of a closed cooling circuit equipped with an external motor cooler (12). 14. A method according to claim 1, characterised in supporting the at least one shaft (9) by magnetic bearings (11). 15. An apparatus for protection of compressor modules against undesirable influx of contaminated gas, comprising a pressure housing (3) which by means of one of more sealing elements (4) is generally divided into a first compartment (8) equipped with a compressor (2) and a second compartment (7) equipped with a gas-filled motor (1), the compressor and the motor being drivably connected to each other by at least one shaft (9), characterised in that the second compartment (7) with motor (1) is protected against direct influx of contaminated gas from the first compartment (8) with compressor (2) by means of compressed gas that is supplied from a withdrawal point (13) at the first or intermediate stage of the compressor, or from the compressor outlet (16), and that the compressed gas is introduced directly into the seal (4) or in between two or more seals so as to flow through the at least one seal (4) back to the first compartment (8) with compressor (2). 16. An apparatus according to claim 15, characterised in that the compressed gas from the compressor (2) is introduced into the seal (4) or in between two or more seals via an external pipeline (14) or an internal bore. 17. An apparatus according to claim 15, characterised in that the compressor module is installed under or above water, on platforms or onshore. 18. An apparatus according to claim 15, characterised in that the compressed gas from the compressor (2) is introduced into the seal (4) or in between two or more seals via a gas treatment unit (17) connected to the external pipeline (14) or the internal bore. 19. An apparatus according to claim 15, characterised in that the second compartment (7) with motor (1) is cooled by use of a closed cooling circuit equipped with an external motor cooler (12). 20. An apparatus according to claim 15, characterised in that the at least one shaft (9) is supported by magnetic bearings (11).
