Maintenance is one of the most important activities in the shipyard industry. However, sometimes it is not supported by adequate services from the shipyard, where inaccuracy in estimating the duration of the ship maintenance is still common. This makes estimation of ship maintenance duration is crucial. This paper uses data mining approach, i.e., CART (Classification And Regression Tree) to estimate the duration of ship maintenance that is limited to dock works or which is known as dry docking.
