“…The tool has been created with intention to give a strict guideline during the Evaluation of Ship's Planned Maintenance System databases, and by enforcing some rules to decrease the subjectivity (Hû et al 1999) of the evaluator (researcher). The Methodology has been tested in operation on several databases and the functionality of the Methodology has been established, as well as reliability of obtained results (Stazić et al 2017). Verifi cation of the functioning of the Methodology has been performed and published (Mišuraet et al 2019) and obtained results were similar to the results during development of the Methodology.…”

“…This time all evaluators were using the Methodology, going through databases and answering to previously prepared questions (the Questionnaire) about the database. The Questionnaire is main part of the Evaluation Methodology for Ship's Planned Maintenance System Database and it is intended to ''be simple and useful tool for the evaluation of all ships Planned Maintenance System databases'' (Stazić et al 2017).…”

Ship's Planned Maintenance Systems are in use for a long period of time, but database quality, confi guration and content are still not standardized. Factors affecting the database quality, confi guration and content are the quality of raw data, experience and knowledge of database creation team, importance given to computerized PMS and care assigned to evaluation of fi nished product. Evaluation of fi nished product, i.e. ship's Planned Maintenance System Database is an action requiring specifi ed knowledge and qualifi cations, as well as experience in performing the task. Even when evaluators fulfi ll all needed requirements, credibility of the obtained results is questionable due to their subjectivity. One of the tools to decrease that problem is the Evaluation Methodology for Ship's Planned Maintenance System Database. A research, described in the paper, has been performed to test that aspect of the Methodology. Three Ships Planned Maintenance System Databases were evaluated by four different evaluators, fi rst using only their experience, then using the Methodology. Results of the research are presented in the paper together with comparison of fi ndings. All presented points that usage of the Methodology is a necessity during evaluations of ship's Planned Maintenance System Databases.

This paper analyzes the shipowner's role in the development process of ship's computerized planned maintenance system database, paying specific attention to his/her impact on database quality grades resemblance equalization. The paper describes the database development process from the realization that the database is needed to the installation on board vessel, and all shipowner's and developer's actions in the process.The computerized databases of five shipping companies were tested using questionnaire developed for this purpose. of office user's workload with regard to the administration and correction of data besides database quality grades: that data serves to portrait the relation between data quality in the databases and importance given to the process of development and maintenance of the databases. The analysis of the results yields numerical values as indicators of shipowner's input on the resemblance of grades of both scenarios and on the database quality grades resemblance equalization.The conclusion shows how the shipowner affects the ship's computerized planned maintenance system database and what actions should be performed to obtain the final product (database, i.e. data in the database) as good as possible and, thus, maintenance of the ship and the whole system.The expected results of the paper are: -To analyze in detail the database ordering and development process, -To pinpoint controlling areas for the database quality, -To analyze the shipowner's impact on the database quality grades resemblance equalization.

“…Ships planned maintenance is a complete system that is carried out mainly by using a computer program specifi cally designed for this purpose. Computerized PMS (Planned maintenance systems) are in use for more than thirty years [18], during which time they have become an important and irreplaceable factor in the maintenance of ship and ships systems.…”

The paper presents the initial case of a research of analysing maintenance interval adjustment in the shipping industry. This case is an example of the adjustment of the maintenance interval carried out by ship's crew on starting air compressor system. The example is found and followed through the records in the computerized Planned Maintenance System. Maintenance interval adjustment proposal and actual adjustment were carried out based on user's experience, after rechecking maintenance data and actual machinery condition, without theoretical approach or analysis. That process created new maintenance plan which is in use on the system for past ten years. Missing actions in the process, i.e. theoretical analysis of the initial and modifi ed maintenance, are performed using the MA-CAD method with a modifi ed reliability testing and are described in the paper. Results obtained by the theoretical analysis are compared with the requested and performed modifi cation of the Maintenance Plan and a conclusion about performed action has been derived. Sažetak U radu je predstavljen inicijalni slučaj istraživanja analize podešavanja intervala održavanja u brodskoj industriji. Ovaj slučaj je primjer podešavanja intervala održavanja koji obavlja brodska posada pri pokretanju sustava kompresora. Primjer smo pronašli i pratili kroz evidenciju u računalnom sustavu planiranog održavanja. Prijedlog podešavanja intervala održavanja i stvarno podešavanje provedeni su na temelju iskustva korisnika nakon ponovne provjere podataka o održavanju i stvarnog stanja stroja bez teorijskog pristupa ili analize. Taj je postupak rezultirao novim planom održavanja koji se u sustavu koristi posljednjih deset godina. Radnje koje nedostaju u tom postupku, tj. teorijska analiza inicijalnog i modifi ciranog održavanja, provedene su primjenom MA-CAD metode s modifi ciranim ispitivanjem pouzdanosti i opisane su u ovom radu. Rezultati dobiveni teorijskom analizom uspoređuju se s traženom i izvedenom modifi kacijom Plana održavanja i donesen je zaključak o izvršenim radnjama.
