MARINA OIC-EW Theoretical Exam study guide
MARINA OIC-EW Theoretical Exam · Work through your exam, one topic at a time.
The MARINA OIC-EW Theoretical Examination is the written knowledge assessment that a marine engineer in the Philippines must pass as part of the process for a Certificate of Competency as Officer in Charge of an Engineering Watch. It is aimed at engineers who already hold the required sea service and lower-level certification and are moving into a watchkeeping role. The MARINA OIC-EW Theoretical Exam study guide has 8 sections and about 2,892 words.
01Marine Engineering Knowledge (Main Propulsion and Auxiliary Machinery)
This domain tests whether you can explain what is happening inside the propulsion plant and auxiliaries from the readings you record, and whether you can put numbers on it. Slow-speed two-stroke: uniflow scavenging through scavenge ports, exhaust valve, separate cylinder lubrication (high-BN oil), constant-pressure turbocharging, crosshead guides lubricated from system oil.
381 words, about 2 min02Marine Electrical, Electronic and Control Engineering
The exam checks generation, distribution, protection and the control loops behind alarms, not the ability to redraw wiring diagrams from memory. Synchronise on voltage, frequency, phase sequence and phase angle before closing the breaker.
359 words, about 2 min03Maintenance and Repair at the Operational Level
This domain examines planned maintenance, condition monitoring, defect reporting and how maintenance work is controlled under the safety management system. Jobs are scheduled by running hours or calendar interval, recorded, signed off, and defects raised in writing so the office and class can see them.
366 words, about 2 min04Controlling the Operation of the Ship and Care for Persons on Board
This domain tests shipboard organisation, hours of rest, drills, hygiene and the human-element duties of the engineer officer. STCW: minimum 10 hours rest in any 24-hour period and 77 hours in any 7-day period; rest may be split into no more than two periods, one of at least 6 hours, and the interval between consecutive rest periods must not exceed 14 hours.
367 words, about 2 min05Ship Construction and Stability
The exam tests the structural members that keep the hull together and the stability numbers that decide whether a load or a weight shift is safe. Keel, floors, girders, longitudinals, frames, transverse and longitudinal bulkheads, double bottom, deep tanks, hatch coamings, watertight doors.
362 words, about 2 min06Maritime Law, Conventions and National Regulations (STCW, MARPOL, SOLAS, MLC, ISM)
This domain covers the instruments an engineer is inspected against: STCW, MARPOL, SOLAS, MLC and the ISM Code, plus the role of the flag administration. STCW: chapters I to VIII, certificates of competency and endorsements, watchkeeping, rest hours, 2010 Manila amendments.
342 words, about 2 min07Ship Safety, Pollution Prevention and Emergency Procedures
This domain tests firefighting, life-saving appliances, pollution response and the correct first actions in an emergency. Fire tetrahedron: fuel, oxygen, heat, chain reaction.
361 words, about 2 min08Watchkeeping, Engineering Practice and Resource Management
The exam checks the routines of the engineering watch and the non-technical skills that prevent accidents. Take over only when satisfied: parameters normal, outstanding defects known, work in progress and isolations listed, bridge informed.
