A connector arrangement for conducting liquid urea solutions. The connector arrangement includes a distributor, with at least three connecting elements, and a connecting component, located between the connecting elements, with inner channels running within the connecting component. Three individual lines having connecting means are connected to the connecting elements of the distributor by the connecting means, and a housing surrounds the distributor and at least a part of the individual line. The distributor is disposed in the housing together with end sections of the connected individual lines. A channel line inner diameter of the inner channels and a total length of the inner channels and a wall thickness of the distributor in the connecting component are dimensioned such that ice pressure on the distributor, which occurs as a result of the freezing of a liquid within the distributor, does not result in any destruction.

The present invention relates to a method of testing an unbonded flexible pipe. The unbonded flexible pipe has a length and a longitudinal axis and comprises, from the inside and out, an internal armour layer, an internal pressure sheath, at least one external amour layer and an outer sheath. At least one of the layers comprises an optical sensor connected to an optical monitoring system and at least one of the armour layers is a metallic and electrically conductive amour layer. The method makes it possible to test an electrical heating system and an optical sensor substantially simultaneously.

A clamping device (40) for providing an electrical connection between a subsea pipeline (1) and an electrical conductor (31). The device has a clamp element (41) comprising a first leg (41a) having a first leg end (41c) and a second leg (41b) having a second leg end (41d). The legs (41a, 41b) are configured to be provided on respective sides of the pipeline (1). The clamping device has a releasable tensioning device (48) connected to one of the legs (41a, 41b). The clamping device (40) has a first state, in which the ends (41c, 41d) of the first and second legs (41a, 41b) are provided at a first distance (d1) away from each other. The clamping device (40) has a second state, in which the tensioning device (48) is tensioned, causing the ends (41c, 41d) of the first and second legs (41a, 41b) to be at a second distance (d2) away from each other, the second distance (d2) being larger than the first distance (d1). The clamping device (40) has a template hole (42) provided in one of the legs (41a, 41b). The clamping device (40) comprises a connector member (44) provided in the template hole (42). The connector member (44) is mechanically connected to the clamp element (41). The clamping device (40) has a third state, in which the tensioning device (48) is released, causing the connector member (44) to be pressed towards the pipeline (1).

The present invention relates to a method and a system comprising a floating unit for processing, handling or storing a fluid and at least one unbonded flexible pipe for transporting said fluid to the floating unit. The unbonded flexible pipe comprises an electric heating system, and the temperature of the fluid in the unbonded flexible pipe is measured and the measured temperature is used to control the electrical input to the electric heating system in the unbonded flexible pipe.
