Welcome to the website where you can pass online the CES CBT CD-301 test on the subject «Crane Operations». Practice like this will help you as a marine specialist improve your knowledge with the help of online studying and appraisal practice. CES 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.
Current test contains Seagull CES questions on the subject «Crane Operations». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Crane Operations» subject includes theoretical and practical information about advanced training for work on any type of vessel. This test provides a comprehensive understanding of the safe and efficient operation of cranes used in maritime environments. Participants will learn about various types of cranes, their components and their operating principles. They will gain knowledge of relevant safety regulations and procedures, including load charts, lifting techniques and emergency procedures. Through testing, they will develop the practical skills required to operate cranes safely and efficiently, ensuring the safe handling of cargo and minimizing risks. This advanced training prepares individuals to operate cranes effectively, contributing to the smooth and efficient flow of cargo operations on board vessels.
On this site Crew Evaluation System Test on the subject «Crane Operations» contains 37 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.

A ship is taking stores, using a provisions gantry crane and cargo net, lifting approximately ten loads, some palletised, from a barge alongside into the stores flat behind the accommodation. How should the loads be controlled and why?
The loads should be brought on board as quickly as possible, in order to save paying overtime for the delivery barge. It is up to the cooks and stewards to clear the loads as quickly as they can.
The loads should be reduced in size and number of boxes and packages to that which can be handled by the cook and stewards without any overlap or delay. The rate of loading should be such that they just have enough time to clear one load before the next arrives.
Due time should be allowed to unload one net and clear the handling area before the next lift is brought on board. This is to avoid anyone working under a suspended load.
