1. 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 a first gas supply circuit of the high-pressure gas consuming apparatus, comprising at least one pump configured to pump the gas collected in the liquid state into the tank,
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 the vapor state from the tank to a pressure compatible with the requirements of the low-pressure gas-consuming apparatus, and
a gas return line connected to the second supply circuit downstream of the compressor and extending to the tank, the supply system comprising at least a first heat exchanger and at least a second heat exchanger each configured to exchange heat between the gas circulating in the return line in the vapor state and the gas in the liquid state circulating in the first supply circuit, the first supply circuit comprising an additional pump interposed between the first heat exchanger and the second heat exchanger.
