<p>The present invention is a method and system for supplying grease to maintain a sealed well during deployment of line, in particular braided electrical wire. The subsea grease cartridge system (100) includes a subsea assembly (102); first and second grease containers (104 and 106) filled with grease; a pump (108); a switch (110); and a restoring device (128) to replenish grease containers. The method of operating the grease cartridge system (100) includes: attaching first and second grease containers (104 and 106) to the subsea assembly (102); applying hydraulic pressure to the first grease container (104); pumping the grease of the first grease container (104) to a grease head; switching hydraulic pressure from the first grease container (104) to the second grease container (106) instantaneously when the first grease container (104) becomes unable to supply grease properly; and pumping the grease of the second grease container (106) to the grease head. The method includes replenishing containers from cartridges and switching back and forth between the filled grease containers.</p> |
