BD Deck Officer Class 2 (Chief Mate) study plan

Derive a celestial line of position from a sextant altitude, assumed position, and almanac data, showing every step and the intercept.

Compute a terrestrial position fix from three simultaneous bearings and a running fix from two bearings taken on different courses.

Explain how to verify compass error by amplitude and azimuth methods and calculate the resulting deviation and variation.

Construct a day's passage plan between two arbitrary coastal positions, including waypoints, course to steer, distance, ETA, and under-keel clearance checks.

Set up an ECDIS route and appraise route safety against a stated safety contour, safety depth, and no-go areas.

Compare the limitations of GNSS, radar, and ECDIS in coastal pilotage and list at least three failure modes with mitigations.

Calculate initial and final metacentric heights from a loading condition and interpret the result against a stated minimum stability criterion.

Solve three statical stability curve problems: determine range of stability, angle of maximum GZ, and effect of adding a weight high on the vessel.

Produce a cargo stowage plan for a mixed general-cargo consignment, assigning slots by weight, compatibility, and port rotation.

Calculate the effects of a partially filled tank and a suspended weight on stability, stating the correction applied in each case.

Explain the structural members and load paths of a bulk carrier and identify three stress concentrations during heavy cargo discharge.

Evaluate damage-control actions for a two-compartment flooding case, including the effect on trim, list, and reserve buoyancy.

Analyze a damaged-stability scenario from a stated set of tank soundings and produce the final list, trim, and freeboard.

Outline the master's responsibilities for vessel stability and watertight integrity during ballast exchange and cargo operations.

Design a weekly on-board safety and familiarization drill schedule covering fire, abandon-ship, and enclosed-space entry.

Evaluate fatigue, workload, and rest-hour rules against a two-week watch schedule and identify compliance gaps.

Inspect a cargo-handling gear register and produce a 12-item pre-use checklist for derricks, cranes, and lifting slings.

Calculate cargo ventilation requirements and dew-point margins for a hygroscopic cargo, stating when ventilation must stop.

Draft a toolbox talk on safe entry into a cargo hold, including atmosphere testing and rescue arrangements.

Compare the requirements for cargo securing manuals with practical lashing calculations for a heavy lift.

Apply the collision regulations to six crossing, overtaking, and restricted-visibility scenarios and state the required action.

Outline the survey, certification, and reporting obligations for a vessel after a pollution incident.

Produce a fire-control plan for an engine-room fire, covering boundary cooling, isolation, fixed-system release, and re-entry.

Explain the legal and operational steps for responding to a person-overboard and a serious injury under the applicable conventions.

Distinguish GMDSS sea areas and select the correct distress and safety communication equipment for each.

Demonstrate the procedure for a DSC distress alert, follow-on voice distress, and cancellation, listing the exact message elements.

Interpret a synoptic chart: locate a frontal system, estimate its movement, and predict wind shift and sea state at a given position.

Explain how ECDIS route monitoring, alarms, and under-keel clearance settings interact during a heavy-weather passage.

Plan and execute a simulated berthing manoeuvre, stating tug use, approach angle, and abort criteria for a stated wind and current.

Apply bridge resource management principles to a bridge-team scenario, assigning roles, challenge-and-response, and a shared mental model.

Complete a timed mixed review across all nine domains and classify every error by cause.

Build a personal 30-day maintenance schedule to retain weak areas after the plan ends.
