Effective maintenance of marine equipment is crucial to reducing accident rates. Consequently, the need for investments to ensure the quality of the services is essential. Maintenance performance can be improved by developing human potential through technical training, definition, creation of skills in employees, and adoption of tools that ensure the effectiveness of this training. Technical training may fail, and employees not well trained can impact the quality of services and products and not meet customer expectations. The lack of a robust effectiveness evaluation process may lead to failure in the training program. Research shows that companies, in general, cannot verify the effectiveness of their training. This fact was observed in a North American offshore maritime support company with a branch in Brazil, showing the need for improvement. The objective of this study is to demonstrate how Kirkpatrick`s four levels of assessment (Reaction, Learning, Behavior, and Results) can be used to manage training in the maritime support company, showing their applicability as a tool for continuous quality improvement and reduced risk of failure in training. Kirkpatrick`s model, known for involving simple questions, is applied in different contexts as a tool for continuous improvement in training management. A case study was carried out on an AHTS maritime support vessel. Employees and their respective leaders completed a survey, operational and quality data were reviewed to obtain the necessary information. The results confirm that it is possible to guarantee the effectiveness of technical training using the proposed method, demonstrating that it is adequate for each assessment level. The study shows that Kirkpatrick`s four assessment levels can improve the training program and reduce the risk of training failure and operational failure due to inadequate training.
