Abstract
A sea water system comprises, an inlet conduit assembly, a ballast tank and an overflow arrangement arranged in fluid communication with the inlet conduit assembly. The inlet conduit assembly provides a fluid communication between ambient environment and the ballast tank. A first pump assembly is arranged in the inlet conduit assembly for pumping sea water through at least a first conduit portion towards the ballast tank. A second pump assembly is arranged in fluid communication with the ballast tank and is arranged for pumping sea water from the ballast tank through an outlet conduit assembly arranged after the second pump assembly. The second pump assembly and the outlet conduit assembly are separate from the inlet conduit assembly. The sea water system may be arranged on a floating vessel.
Claims29
A sea water system, comprising:
- an inlet conduit assembly, a ballast tank and an overflow arrangement arranged in fluid communication with the inlet conduit assembly, the inlet conduit assembly providing fluid communication between ambient environment and the ballast tank;
- a first pump assembly disposed in the inlet conduit assembly for pumping sea water through at least a first conduit portion of the inlet conduit assembly towards the ballast tank;
- a second pump assembly in fluid communication with the ballast tank for pumping sea water from the ballast tank through an outlet conduit assembly arranged after the second pump assembly, characterized in that said overflow arrangement has an extension to a vertical level to thereby determine a maximum sea water pressure in said ballast tank, the second pump assembly and the outlet conduit assembly being separate from the inlet conduit assembly, wherein the inlet conduit assembly comprises, in sequence, the first conduit portion, an intermediate branch portion and a second conduit portion, wherein at least a second conduit assembly of the sea water system branches off from the intermediate branch portion, and wherein the intermediate branch portion is an intermediate tank adapted to hold sea water for further distribution.
A sea water system, comprising:
- an inlet conduit assembly, a ballast tank, and an overflow arrangement in fluid communication with each other and an ambient environment, wherein the overflow arrangement is adapted to determine a maximum sea water pressure in the ballast tank;
- a first pump assembly disposed in the inlet conduit assembly and adapted to transfer sea water through at least a first conduit portion of the inlet conduit assembly toward the ballast tank;
- and
- a second pump assembly in fluid communication with the ballast tank adapted to transfer sea water from the ballast tank through an outlet conduit assembly disposed downstream from the second pump assembly, wherein the second pump assembly and the outlet conduit assembly are separate from the inlet conduit assembly, wherein the inlet conduit assembly comprises, in sequence, the first conduit portion, an intermediate branch portion, and a second conduit portion, wherein at least a second conduit assembly of the sea water system branches off from the intermediate branch portion, wherein the intermediate branch portion is an intermediate tank adapted to hold sea water for further distribution, and wherein the overflow arrangement is connected to the intermediate tank.
A sea water system, comprising:

- a first pump assembly disposed in the inlet conduit assembly and adapted to transfer sea water through at least a first conduit portion of the inlet conduit assembly toward the ballast tank;
- and
- a second pump assembly in fluid communication with the ballast tank adapted to transfer sea water from the ballast tank through an outlet conduit assembly disposed downstream from the second pump assembly, wherein the second pump assembly and the outlet conduit assembly are separate from the inlet conduit assembly, wherein the inlet conduit assembly comprises, in sequence, the first conduit portion, an intermediate branch portion, and a second conduit portion, wherein at least a second conduit assembly of the sea water system branches off from the intermediate branch portion, wherein the intermediate branch portion is an intermediate tank adapted to hold sea water for further distribution, and wherein the overflow arrangement is formed such that a first overflow level provides a first outflow area from the intermediate tank and a second overflow level provides a second outflow area from the intermediate tank, the second outflow area being greater than the first outflow area.
