Indonesia is a maritime country where most of its territory is in the form of oceans, so many people utilize its marine resources. The sea is currently widely used as a transportation medium for people and logistics using commercial ships. With so many commercial ships in Indonesia, the ship repair industry is also increasingly needed because it requires regular maintenance and repair according to the rules of ship classification. Hull repair treatment includes scraping, washing with fresh water, blasting (full blasting, sweep blasting, and spot blasting), painting, and replating (based on ultrasonic thickness test results). This research will focus more on container ships, bulk carriers, and oil tankers. In ship repair, the condition of the ship’s body, especially the hull, is the most critical concern. The calculation of the volume of hull work on each shipyard is different, making it difficult for the ship owner to estimate the repair time to be carried out. In this case, this study aims to determine the efficiency of the volume of hull repair work on commercial ships so that maintenance/repair work can run optimally. The method used is the calculation of Lloyd’s Registers with the Analytical Hierarchy Process (AHP). The analysis results show that the ship’s hull work is significantly different on the MT. Cosmic 15 because it has a difference in calculations from the shipyard with Lloyd’s, which is 203.636 m2. In the Analytical Hierarchy Process (AHP) analysis, the calculation of CR (Consistency Ratio) gets inconsistent results because the value is more than 0.1, namely 5.303. This is because of the data on the hull area of MT. Cosmic 15 is different in each shipyard where the ship docks.
