CES/CBT based on practical information and marine specialists experience.

CES tests developed for evaluating seaman basic knowledge by Seagull Company (rebranded as «OTG»), is an evaluating online-tool, used for revealing any professional preparation needed in specific fields of knowledge, defined by STCW.

CES tests have proven themselves as good tools for the selection and recruitment process, as well as advancing the level of knowledge of the current officers and crew. Ocean Technologies Group use various subjects for question creation, which includes:

  • Crowd and Crisis Management;
  • Integrated Navigation System (INS);
  • Ballast water management;
  • Handling and Stowage;
  • Vessel operation management and safety;
  • Marine engineering;
  • Maintenance and repair, etc.

«AutoChief4 Sulzer DENIS1» subject includes theoretical and practical information about safety working with electrical equipment. Knowledge of this information directly shows employee’s competence who holds a relevant post on a vessel. AutoChief4 Sulzer DENIS1 is a sophisticated control system designed for marine vessels equipped with Sulzer engines. It offers comprehensive automation and supervision of engine operations, ensuring smooth and efficient functionality. The AutoChief4 system incorporates advanced algorithms and sensors to monitor key parameters like fuel injection, combustion, exhaust emissions, and cooling water temperature. By analyzing and optimizing these variables in real-time, it enhances performance, increases fuel efficiency, and reduces environmental impact. Additionally, the AutoChief4 provides alarm notifications and safety features, contributing to the overall reliability and safety of the engine system.
