Maintenance
The pumpman's job is to keep the liquid cargo system on a tanker running. The liquid cargo system consists of several components. A major component is the pumps themselves, including not only the liquid cargo transfer pumps but also the liquid cargo stripping pumps. Another component consists of the equipment that conditions the cargo, including liquid cargo coalescers and separators, strainers, and filters. The third component consists of all the piping, valves, fittings, and deck machinery directly related to the transfer of liquid cargo.
The pumpman's job has three aspects: repairing equipment when it breaks, monitoring equipment to ensure it is working, and maintaining equipment to prevent breakage. Many organizations, such as the United States Navy use planned- and preventive-maintenance systems to guide the pumpman in identifying and scheduling required maintenance actions.
Some common activities include rebuilding valves pumps and correcting leaks in the cargo system. Pumpmen also often repack valves and glands. Pumpmen also spend a lot of time lubricating parts, such as glands, bearings and reach rods.
On some ships, pumpmen are responsible for the ballast system, room heating systems, and other engine department duties.

Famous quotes containing the word maintenance:
“... in the fierce competition of modern society the only class left in the country possessing leisure is that of women supported in easy circumstances by husband or father, and it is to this class we must look for the maintenance of cultivated and refined tastes, for that value and pursuit of knowledge and of art for their own sakes which can alone save society from degenerating into a huge machine for making money, and gratifying the love of sensual luxury.”
—Mrs. H. O. Ward (1824–1899)
“In public buildings set aside for the care and maintenance of the goods of the middle ages, a staff of civil service art attendants praise all the dead, irrelevant scribblings and scrawlings that, at best, have only historical interest for idiots and layabouts.”
—George Grosz (1893–1959)
“However patriarchal the world, at home the child knows that his mother is the source of all power. The hand that rocks the cradle rules his world. . . . The son never forgets that he owes his life to his mother, not just the creation of it but the maintenance of it, and that he owes her a debt he cannot conceivably repay, but which she may call in at any time.”
—Frank Pittman (20th century)
