MARINA OIC-EW Examination Permit

MARINA EAD administers the OIC-EW theoretical exam as 17 independent competences totaling 205 published items on the official permit, with 70% or 80% passing marks each and a ~200-minute full-paper design. Candidates schedule at least two competences per sitting and must pass all competences within 24 months. Confirm current MARINA EAD fees; practical assessment is separate from this theoretical exam.

Sample MARINA OIC-EW Theoretical Exam Practice Questions

Try these sample questions to test your MARINA OIC-EW Theoretical Exam exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under STCW Code Section A-VIII/2, what is the primary purpose of maintaining an effective engineering watch?
A.To maximize fuel consumption regardless of conditions
B.To ensure the safe and proper operation of the ship's machinery at all times
C.To allow the OOW to leave the machinery space unattended
D.To reduce logbook entries to a minimum
Explanation: STCW Section A-VIII/2 requires that an engineering watch be maintained to ensure safe and proper operation of all machinery affecting the safety of the ship. The watch must not be left in a condition that prevents manual control when needed.
2When taking over an engineering watch, which document should the relieving engineer first verify is current and understood?
A.The ship's cargo manifest only
B.Standing orders and special instructions from the chief engineer
C.The crew vacation roster
D.The galley provisioning list
Explanation: STCW Table A-III/1 and MARINA OIC-EW C1 require the reliever to confirm standing orders and the status of machinery before accepting the watch. Standing orders define operational limits and priorities for that voyage.
3During a routine engineering watch, bilge high-level alarms activate in the engine room. What is the correct immediate action?
A.Silence the alarm and continue normal operations
B.Investigate the source, take corrective action, and log the event
C.Wait for the next watchkeeper to investigate
D.Discharge bilges directly overboard without treatment
Explanation: Watchkeepers must respond promptly to alarms, investigate causes, take corrective action, and record events in the engine-room log. Ignoring or delaying response violates safe watchkeeping principles under STCW A-VIII/2.
4Which parameter in the engine-room log most directly indicates possible crankcase lubricating-oil dilution by fuel?
A.Rudder angle
B.Fuel oil viscosity at storage tank
C.Rise in crankcase oil level combined with reduced oil viscosity readings
D.Fresh water production rate
Explanation: Fuel dilution occurs when unburned fuel leaks past piston rings into the crankcase, raising the sump oil level while diluting the lubricant. This reduces viscosity and lubricating effectiveness, requiring trending of oil analysis results and corrective action.
5Before handing over the engineering watch, the outgoing engineer must ensure the reliever is informed about which of the following?
A.Only the current barometric pressure
B.Status of machinery under watch, tank levels, and any defects or restrictions
C.The next port entertainment schedule
D.Personal email passwords
Explanation: Handover requires relaying machinery status, tank levels, defects, standing orders compliance, and any operational restrictions so the reliever can maintain a safe watch per STCW Table A-III/1 C1.
6Engine-room resource management (ERM) during a watch emphasizes which principle when multiple tasks compete for attention?
A.Complete all tasks simultaneously without prioritization
B.Allocate, assign, and prioritize resources to maintain safety first
C.Defer all non-routine work until arrival in port regardless of risk
D.Communicate only in the native language of the chief engineer
Explanation: STCW Table A-III/1 C1.4 requires knowledge of ERM including allocation, assignment, and prioritization of resources with safety as the highest priority during engineering operations.
7When changing from remote/automatic control to local manual control of main engine, the watchkeeper must first:
A.Shut down the main engine immediately without notice
B.Verify local control is available, inform relevant personnel, and follow company procedures
C.Disable all alarms to prevent nuisance activations
D.Leave the control room unattended
Explanation: STCW requires safe changeover procedures between remote/automatic and local control. The watchkeeper verifies readiness, communicates with the bridge and chief engineer as required, and follows standing orders.
8Which action best demonstrates proper maintenance of machinery-space logs during a watch?
A.Recording only when the chief engineer is onboard
B.Entering significant readings, alarms, and operational changes promptly and accurately
C.Copying previous watch entries without verification
D.Using pencil so entries can be erased later
Explanation: Logs must record movements and activities relating to ship engineering systems with readings taken at appropriate intervals. Prompt accurate entries support trend analysis and legal compliance.
9During unmanned machinery space (UMS) operation, who retains responsibility for machinery safety when the duty engineer is resting?
A.No one; automation fully replaces human responsibility
B.The designated duty engineer who must respond to alarms and be capable of manual intervention
C.The catering department
D.Only the master on the bridge
Explanation: Under UMS arrangements, a designated engineer remains responsible for responding to alarms and taking manual control when required. Automation supplements but does not replace watchkeeping responsibility.
10If a fuel-oil leak is detected on a hot surface during the watch, the immediate priority is to:
A.Continue operation and monitor the leak
B.Stop the leak source if safe, prevent ignition, and initiate fire-prevention measures
C.Open all engine-room ventilation to maximum immediately without assessment
D.Photograph the leak and post on social media
Explanation: Oil on hot surfaces creates severe fire risk. The watchkeeper must secure the leak if safely possible, prevent ignition, and follow emergency procedures per STCW safety and emergency requirements in C1.

About the MARINA OIC-EW Theoretical Exam Exam

The MARINA Officer in Charge of an Engineering Watch (OIC-EW) Theoretical Examination is the competence-based written assessment for operational-level engine officers seeking STCW certification in the Philippines. It covers marine engineering, electrical/electronic systems, maintenance and repair, and controlling the operation of the ship across 17 published competences. This metadata describes the theoretical examination only; a separate practical assessment is required for Certificate of Competency issuance.

Assessment

Competence-based theoretical examination across 17 STCW operational-level engine competences (F1 Marine Engineering, F2 Electrical/Electronic, F3 Maintenance, F4 Controlling Operation). Each competence is examined and passed independently with its own item count and passing percentage (70% or 80%). Full paper design ~200 minutes. Separate practical assessment is required for COC issuance.

Time Limit

Approximately 200 minutes for the full theoretical paper in one sitting, plus administrative delays (MARINA OIC-EW Examination Permit)

Passing Score

70% or 80% per competence as listed on the official OIC-EW Examination Permit

Exam Fee

Confirm current MARINA EAD examination fee schedule — Official Receipt required on exam day per Examination Permit (Maritime Industry Authority (MARINA) — STCW Office / Examination and Assessment Division (EAD))
