Subsea Distribution System More than10.000 units installed since 1993 Picture taken 2004 of the first jumpers installed on the Snorre field in 1993 A subsea pressure and temperature compensated system. Using oil filled hoses ensures that the system always maintains an internal over-pressure relative to ambient throughout its working depth and temperature range. /11/ Copyright Siemens AS 2012.
