OPERATIONAL LEVEL – ENGINE REPUBLIC OF THE PHILIPPINES DEPARTMENT OF TRANSPORTATION MARITIME INDUSTRY AUTHORITY STCW OFFICE GUIDE QUESTIONNAIRES for seafarers The Annual Publication of Database of Questionnaires is mandated in Republic Act 10635 or the Act Establishing the Maritime Industry Authority (MARINA) as the Single Maritime Administration Responsible for the Implementation and Enforcement of the 1978 International Convention on Standards of Training, Certification and Watchkeeping for Seafarers, 1978, as amended and International Agreements or Covenants related thereto and its Implementing Rules and Regulations. These sample questions have been reviewed and validated by our respective Board of Examiners which may serve as a guide for the review of aspiring Marine Deck and Engineering Officers, towards the successful completion of the Theoretical Examination. The following sample questions do not reflect the actual set of database of questions given during the theoretical examination. Examinees are encouraged to study the contained sample questions and probable answers as they are intended to give an indication of the format and difficulty level of the theoretical examination. You may access these guide questionnaires with your smart gadgets anywhere and anytime at your convenience. Please consider the environment before printing. Thank you.
