Abstract: The present invention provides a fluid injection system (11) which transitions between a maintenance mode wherein an outlet (15) is closed and no fluid is discharged through the outlet, and an operation mode, wherein the outlet is open and fluid is discharged through the outlet. The fluid injection system injects a first fluid transported in a first pipeline (21) with a second fluid, wherein there is a temperature differential between the first fluid and the second fluid. The fluid injection system comprises a holding tank (49) for storing the second fluid, a cooling means (35) to cool the second fluid, and a pump (39) for delivering the second fluid into the first pipeline.

Abstract: An insulation system comprising low density foam with a tensile modulus less than 5 MPa at ambient conditions and less than 10 MPa under cryogenic service conditions.

Abstract: The invention relates to a cold-insulated fixed-point pipe support for a low-temperature pipeline which includes an insulating system arranged between an outer shell and a supportable low-temperature pipeline having solid thermal insulating material which thermally insulates the pipeline from the low-temperature environment. A rotation-preventing and displacement-preventing device prevents rotation and displacement of the thermal insulating material with respect to the pipeline and an outer shell. A fixed-point pipe support is adapted to be fitted and removed in a substantially radial direction over the pipeline, and has at least one division with respect to shape with a division plane thereof extending perpendicular to a cross-sectional plane, and having a connecting device for releasable connecting and fixing shaped parts formed by the division.
