Claims

1. A lead-through module (10) for discharging exhaust gas scrubbing water into the sea through a hull (12) of a marine vessel, characterized by

a flow tube (14) having a first end (14.1 ) and a second end (14.2), wherein the flow tube (14) is of a first grade steel and comprising

o an attachment flange part (18) at the first end of the flow tube (14),

o an outlet flange part (20) at the second end (14.2) of the flow tube (14) extending radially outwards from the second end of the flow tube (14) having an outer periphery (20'),

a planar transition plate (22) of a second grade steel, having an outer periphery (22') and comprising an opening (23) defining an inner periphery (22") of the transition plate (22), wherein the inner periphery (22") of the transition plate (22) conforms with an outer periphery (20') of the outlet flange part (20), and wherein the transition plate (22) is arranged axi- ally flush with, and rigidly connected to the outlet flange part (20) of the flow tube (14).

2. A water lead-through module (10) according to claim 1 , characterized in that the first grade steel and the second grade steel are selected so that corrosion resistance of the first grade steel is higher than corrosion resistance of the second grade steel.

3. A lead-through module (10) according to claim 1 , characterized in that the flow tube (14) is of high-alloy austenitic stainless steel as is defined in EN 1 .4547

4. A water lead-through module (10) according to claim 1 , characterized in that the transition plate is of Grade A steel according to Det Norske Veritas offshore standards.

5. A water lead-through module (10) according to claim 1 , characterized in that a sealed housing (28', 28) is arranged around the flow tube (14) extending from the wall of the flow tube (14) to the transition plate (22).

6. A water lead-through module (10) according to claim 3, characterized in that the flow tube (14) comprises an intermediate flange part (21 ) between the attachment flange part (18) and the outlet flange part (20), wherein an annular housing (28) is arranged around the flow tube (14) extending between the intermediate flange part (21 ) and the transition plate (22).

7. A water lead-through module (10) according to claim 2, characterized in that sealed housing (28', 28) is provided with a leak detector (30).

8. A water lead-through module (10) according to claim 1 , characterized in that the outlet flange part (20) extends radially outwards the flow tube (14) of a distance (D) which is at least 50% of the diameter of the flow tube (14).

9. Method of arranging a water lead-through to a hull (12) of a marine vessel, comprising:

providing a flow tube (14) of a first grade stainless steel having a first end and a second end, wherein the flow tube (14) is provided with an attachment flange part (18) at the first end of the flow tube (14) and an outlet flange part (20) at the second end of the flow tube (14) extending radially outwards from the second end of the flow tube (14) having an outer periphery,

providing a planar transition plate (22) of a second grade steel having an outer periphery and arranging an opening into the transition plate (22) defining an inner periphery of the transition plate (22), such that the inner periphery of the transition plate (22) conforms with an outer periphery of the outlet flange part (20), and

arranging the transition plate (22) axially flush with, and rigidly connecting the transition plate (22) by welding, to the outlet flange part (20) of the flow tube (14),

- providing an opening to the hull (12) of the marine vessel conforming with the outer periphery of the transition plate (22) and rigidly connecting the transition plate (22) to the opening in the hull (12) of the vessel.
