Abstract
A fuel forwarding skid for delivering fuel from a storage area to a plurality of turbines includes at least two pumps for delivering fuel to a skid outlet line. A flow control device is connected to the pumps to control an output of the pumps. A recirculation line is in communication with the skid outlet line and is adapted to return a portion of the fuel in the skid outlet line to the storage area. A flow meter is in communication with the recirculation line to measure a rate of flow in the recirculation line, and the flow control device controls the output of at least one of the pumps in accordance with the rate of flow in the recirculation line.

A fuel forwarding skid for delivering fuel from a storage area to a plurality of turbines, comprising:
- at least two pumps for delivering fuel to at least one skid outlet line;
- at least one flow control device connected to the at least two pumps to control an output of the pumps;
- at least one recirculation line in communication with the at least one skid outlet line and adapted to return a portion of the fuel in the at least one skid outlet line to the storage area;
- and
- at least one flow meter in communication with the at least one recirculation line to measure a rate of flow in the recirculation line,
- wherein the at least one flow control device controls the output of at least one of the pumps in accordance with the rate of flow in the at least one recirculation line.
A method of delivering fuel via a forwarding skid from a storage area to a plurality of turbines, the plurality of turbines including a first group and a second group of turbines, the forwarding skid including at least first and second pumps for delivering the fuel to at least one skid outlet line, and at least one recirculation line in communication with the at least one skid outlet line and adapted to return a portion of the fuel in the at least one skid outlet line to the storage area, comprising:
- providing at least one flow control device connected to the at least first and second pumps to control an output of the pumps;
- providing at least one flow meter in communication with the at least one recirculation line to measure a flow rate in the recirculation line;
- initiating a first demand for a first turbine of the first group of turbines;
- supplying with the first pump the first demand and a first predetermined surplus;
- and
- adjusting the output of the first pump such that the flow rate in the recirculation line achieves a first predetermined value.
