Currently, the Naval Construction Department of SIMA Callao has 09 bridge-type cranes, 01 gantry and 01 semi-gantry. Between 2016 to 2019, it was reflected an increase of 110.21% of the budget in the maintenance of this equipment, risen to the amount of S /. 272,218.54. Likewise, there was evidence of an increase in unscheduled maintenance stops and a decrease in crane availability by 5%. This situation led to the implementation of this project, which aims to improve the maintenance management of bridge, gantry and semi-gantry cranes. For this reason, the Reliability Centered Maintenance (RCM) tool was applied, highlighting its importance in the application of the failure severity analysis methodology (criticality), well known as AMFE. This methodology allowed to identify that electric systems of hoist as well as movement systems were those with the highest frequency of failures, due to the low insulation they presented, as a result of the lack of cleaning and the excessive humidity in the environment. This valuable information made it possible to present an optimized proposal, developing a new maintenance plan based on the RCM. This improvement proposal permitted to demonstrate an increase in the mean time between failures (MTBF) from 312 to 819 days, improving the availability of bridge cranes from 84% to 93% and a reduction of 80% in the cost of corrective maintenance, which led to economic savings of S/ 301,362.4, in comparison to 2019.
