Abstract
A system supplies gas to a high-pressure gas-consuming apparatus and a low-pressure gas-consuming apparatus of a floating structure including a tank. The supply system includes: a first supply circuit, a second supply circuit, a return line, a first heat exchanger and a second heat exchanger. The return line includes a flow-regulating member. The supply system includes a device for managing the supply system which includes a control module to control the flow-regulating member based on the characteristics of the gas.
Claims13
A system for supplying gas to at least one high-pressure gas-consuming apparatus and at least one low-pressure gas-consuming apparatus of a floating structure comprising at least one tank configured to contain the gas, the supply system comprising:
- at least one first circuit supplying gas to the high-pressure gas-consuming apparatus,
- at least one high-pressure evaporator configured to evaporate the gas circulating in the first gas supply circuit,
- at least one second circuit supplying gas to the low-pressure gas-consuming apparatus, comprising at least one compressor configured to compress gas taken in a vapor state into the tank to a pressure compatible with the requirements of the low-pressure gas-consuming apparatus,
- at least one gas return line connected to the second supply circuit downstream of the compressor and extending to the tank,
- at least one first heat exchanger and one second heat exchanger, each configured to exchange heat between the gas circulating in the return line in the vapor state and the gas circulating in the first supply circuit in a liquid state, the first supply circuit comprising a pump interposed between the first heat exchanger and the second heat exchanger, the return line comprising a flow-regulating member arranged between the first heat exchanger and the tank, and
- a management device configured to manage said supply system, said management device comprising at least one first sensor and a first detector respectively configured to determine a temperature and pressure of the gas present in the first supply circuit between the first heat exchanger and the pump, a second sensor configured to determine a temperature of the gas present in the first supply circuit between the tank and the first heat exchanger, a third sensor configured to determine a temperature of the gas present in the return line between the first heat exchanger and the flow-regulating member, the management device comprising a control module configured to control the flow-regulating member according to the characteristics of the gas determined by the first sensor, the second sensor, the third sensor and the first detector.
