Cyber security in the maritime industry became crucial due to both academic researches and incidents. There are academic studies that show vulnerabilities in various navigation equipments such as GPS, ECDIS, AIS and ARPA-Radar. Additionally, there are different cyber incidents around the world. Developments in technology, autonomous ship projects, academic studies and cyber incidents in the sector put in action IMO. As per ISM Code, all shipping companies are mandatory to add “Guidelines on Maritime Cyber Risk Management” manual to their SMS manuals until 1st January 2021. Both OCIMF and CDI failed to be indifferent to developments that are important for tanker operators as well as IMO. While OCIMF added cybersecurity-related questions to vetting programs called TMSA 3 and VIQ 7, CDI also added cybersecurity-related items in SIR 9.8.1 edition. On the other hand, RightShip provides significant vetting service for dry cargo ships. “Inspection and Assessment Report” is issued by RigthShip for dry cargo ships. Questions related with cybersecurity was added with Revision No: 11 dated on 11th May 2017 in “Inspection and Assessment Report”. In this study, cyber security related questions which are asked during TMSA, SIRE and CDI vettings which play a critical role for commercial life of tanker firms, were analyzed. Moreover, questions and efficiency of RightShip that offers vetting service for dry cargo ships, were assessed to maritime cyber security. Also, cybersecurity-related questions in vetting questionnaires were interpreted by the author. These comments rely on benchmarking meetings among tanker operators where the author personally attended, and interview with key persons. Noted observations during vettings may negatively impact both commercial life and reputation of the tanker operators. That’s why the firm names and interviewee names were kept confidential. In this study, it was seen that although IMO demanded verification of cyber security-related implementations for the ship operators until 1st January 2021, this process started earlier for tanker operators.
