Welcome to the website where you can pass online the CBT test on the subject «COLREG (Rev. 7)». Practice like this will help you as a marine specialist improve your knowledge with the help of online studying and appraisal practice. CBT based on practical information and marine specialists experience.
CBT 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.
Test type: STCW.
Module: 0172.
Subject: International Collision Regulations.
Revision: 7.
Vessel type: any.
CBT 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.
Current test contains Seagull CBT questions on the subject «International Collision Regulations (Rev. 7)». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«COLREG» subject includes theoretical and practical information about advanced training for work on any type of vessel. Knowledge of this information directly shows employee’s competence who holds a relevant post on any type of vessel. Individuals trained in CBT 0172 International Collision Regulations (Rev. 7) are responsible for ensuring compliance with international collision regulations while navigating a vessel. Their duties include understanding and applying the rules of the road at sea, maintaining a proper lookout, and taking appropriate actions to prevent collisions. These individuals play a crucial role in promoting maritime safety by effectively implementing collision avoidance measures and responding to navigational challenges in accordance with the established regulations.
On this site Crew Evaluation System Test on the subject «International Collision Regulations» contains 45 questions you need to answer with no possibility to go back to previous question. Therefore, we recommend carefully reading each question and making decision with no hurry. In case you have some difficulty answering, you have also possibility to request a hint.
The test includes two modes. In the Training mode, you go through 45 questions with the option to take a hint, while in the Exam mode, this option is not available. Enjoy!
