Cold-box system and method for power management aboard ships
View Patent ↗A cold-box system includes: a bulk gas tank, and a plurality of cold-box compartments operationally associated with the bulk gas tank. A cold-box apparatus includes a plurality of cold-box compartments operationally associated with a bulk gas tank. In one embodiment the cold-box compartments may be spaced apart from the tank aboard a waterborne platform. The system and apparatus provide redundancy regarding power aboard ship for the bulk gas tank.
1. A cold-box system for shipboard use, comprising:
a single bulk gas storage tank mounted on a ship and constructed to provide fuel for powering the ship;
a plurality of cold-box compartments supported by the single bulk gas storage tank and operationally connected to the single bulk gas storage tank; and within each cold-box compartment of the plurality of cold-box compartments, control and power supply equipment to provide redundancy of the control and power supply equipment for the single bulk gas storage tank.
2. The system of claim 1 , wherein the plurality of cold-box compartments comprises a pair of compartments.
3. The system of claim 1 , wherein a first one of the plurality of compartments is mounted above a second one of said plurality of compartments.
4. The system of claim 1 , wherein each one of the plurality of cold-box compartments comprises at least one hatch for access to an interior of each of said compartments.
5. The system of claim 1 , wherein the single bulk gas storage tank contains a gas comprising LNG.
6. The system of claim 1 , wherein the plurality of cold-box compartments are mounted to the single bulk gas storage tank.
7. A method of providing redundancy of the power systems required for each LNG tank aboard a ship, the method comprising:
installing on the ship at least one cold-box system of claim 1 .
