Maintenance
This module should meet requirements listed in ISM (International Safety Management Code), chapter 5, section 10. The database should be constructed according to the manufacturer's recommendations, and good seamanship practice. The database should include all shipboard vital equipment, and all equipment should have a clearly defined maintenance plan. Performed tasks should be kept in the system as well as notes from crew members performing the task.
Access to various aspects in the system must be selective and programs must have ability to individually recognize users (login ID and password). Best example of this practice is Class requirement that only Chief Engineer have access to jobs linked with Surveys.
Class societies allow special status to ships with well implemented PMS. Survey of various machinery components is performed usually with regular Class surveyor inspection, and it is based on schedule given in Continuous Machinery Survey. Surveyor comes to ship several times per year and inspects various machinery components, determining their condition. Inspection is scheduled every five years and the system is intended to assure good functionality of ship's machinery and therefore safety of the ship. As PMS is increasing overall safety and reliability of the ship, Class societies allow another form of Survey to be performed on the ships with well established PMS. Most of CSM inspections (all except steering gear and pressure vessels) is carried out by Chief Engineer, based on regular PMS jobs, and Class surveyor is coming on board the ship only once a year to inspect items Chief Engineer is not entitled to and to check what items were inspected since last Class inspection.

Famous quotes containing the word maintenance:
“My course is a firm assertion and maintenance of the rights of the colored people of the South according to the Thirteenth, Fourteenth, and Fifteenth Amendments, coupled with a readiness to recognize all Southern people, without regard to past political conduct, who will now go with me heartily and in good faith in support of these principles.”
—Rutherford Birchard Hayes (1822–1893)
“... 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)
