The technique of replenishment at sea (RAS) enables a fleet or naval formation to remain at sea for prolonged periods. RAS is accomplished by means of one or more horizontally oriented rigs that connect the delivering ship with the receiving ship. These transfers may be augmented by vertically oriented transfers that utilize a helicopter.

Replenishment operations must be accomplished in conjunction with and in support of the combatant force's assigned mission or task. The most significant factor to be considered in any planned replenishment is the receiving ship's ability to use the delivering ship's rig.

The supplying ship's primary function in a replenishment operation is the efficient transfer of liquid and/or solid cargo. The rate of transfer is controlled by the customer ship's ability to receive and handle the liquids and solids.

The time required for replenishment must be reduced to a minimum consistent with safety of equipment and personnel.
