Officer Of the Watch Unlimited

Officer Of the Watch - ships of 500Gt and above [OOW Unlimited] STCW Reg II/I

Objectives of this Wikibook
The United Kingdom Maritime and Coastguard Agency (MCA) Officer Of the Watch exam has a a very vast and various syllabus. This Wiki has the purpose to give a reference guide to each point in the syllabus in order to make it more easy to find answers. As I am working on this I have taken the backbone structure of this Wikibook "Yach Officer Exam Guide"

MGN 69 (M) TRAINING AND CERTIFICATION GUIDANCE – PART 11 Conduct of MCA Oral Examinations
All the information give in here are referred back to the Merchant Guidance Notice 69 (M). In particular page 9 to 11.

Plan and conduct a passage including position determination
==== a) passage planning with respect to the use of navigational publications including navigational charts (including ECDIS and RCDS), sailing directions, light lists, tide tables, radio navigational warnings and ship's routeing information; ====

This subject was generated from SOLAS Ch V Regulation 19.2.1.4. The answer is quite broad.

Key points
The passage plan ensures that the bridge management team is fully aware of the vessel intended voyage and of the contingency plans. The plan is from berth to berth and any changes to the intended voyage must be amended in the plan. The master is overall responsible for the plan but may delegate the task of creating it. The plan is consigned into a passage plan book and always available on the bridge.

 * Planning
 * Execution
 * Monitoring

Appraisal
From consulting all relevant publications, all the potential dangers on the voyage are clearly identified. After considering existing routeing schemes, environmental factors reporting systems and vessels traffic services a clear indication of a safe route can be obtained.

The passage planning shall take into consideration:
 * The condition and state of the vessel.
 * Any special characteristics of the cargo.
 * The provision of a competent and well-rested crew.
 * Requirements for up-to-date certificates.
 * Appropriate scale, accurate and up-to-date charts and publications.

Planning
Tracks can be laid on the chart from berth to berth indicating the predetermined margins of error. Danger areas are marked on the charts, as are points, which could be useful for navigation. In the event of an emergency, contingency plans are also considered. The plan is approved by the master prior to sailing and must be kept on board of the vessel for 12 months.

The detailed voyage or passage plan should include the following factors:
 * The plotting of the intended route or track of the voyage or passage on appropriate scale charts.
 * The main elements to ensure safety of life at sea (Safe speed, speed and course alterations, clearance under the keel, contingency plans)
 * The details of the voyage or passage plan should be clearly marked and recorded.

Each voyage or passage plan as well as the details of the plan, should be approved by the ship’s master prior to the commencement of the voyage or passage.

Execution
Once the departure time is known, the estimated time of arrival at the destination can be found. ETA's at critical points in the plan can also be determined. Time of high water and clearer identification can be gained of the conditions the vessel is likely to face the throughout the voyage. Factors which should be taken into account when executing the plan, or deciding on any departure therefrom include:
 * The reliability and condition of the vessel's navigational equipment;
 * Estimated times of arrival at critical points for tide heights and flow;
 * Meteorological conditions, (particularly in areas known to be affected by frequent periods of low visibility) as well as weather routeing information;
 * Daytime versus night-time passing of danger points, and any effect this may have on position fixing accuracy;
 * Traffic conditions, especially at navigational focal points.

Monitoring
The vessel progress is continually checked against the planned route. Any necessary deviations are amended in the plan and the bridge management team advised. The navigational equipment is monitored and checked on passage and prior departure. The plan should be available at all times on the bridge to allow officers of the navigational watch immediate access and reference to the details of the plan.

b) the requirements of ship routeing and mandatory reporting systems;
The answer can be found in SOLAS Ch V - Regulation 10. Basically ship's routeing systems are put in place by countries that believe part of their waters require a specific routing for traffic. More in depth information can be found in SOLAS Ch V - Annex 5. It is important to remember that A ship navigating in or near a traffic separation scheme adopted by IMO shall in particular comply with rule 10 (TSS) of the 1972 Collision Regulations.

c) IALA systems of maritime buoyage;
The  International Association of Marine Aids to Navigation and Lighthouse Authorities  (IALA) Maritime Buoyage System is divided into two regions.
 * Region A includes part of the Atlantic Ocean, Africa, Europe, Asia, Middle East, Australia and part of the Pacific Ocean
 * Region B includes North and South America.

d) electronic navigational systems - limitations and sources of error, methods of correction;

 * MGN 379 (M+F): Use of Electronic Navigation Aids

e) limitations of electronic chart systems including ECDIS and RCDS navigational chart systems;
Solas Ch V - Annex 14

h) to use a sextant, identify and correct errors;
==== i) sources of meteorological information, ability to use and interpret information obtained from ship borne meteorological instruments (the instruments supplied by the Meteorological Office will be taken as standard), knowledge of characteristics of various weather systems, reporting and recording systems. ====

d) understand the use of bridge equipment, including rate of turn indicators, course recorders, echo sounders and NAVTEX;
==== e) knowledge of steering control systems, including automatic pilot, operational procedures and change-over from manual to automatic control and vice-versa - adjustment of controls for optimum performance; ====

b) use and care of mooring lines and associated equipment;
==== c) helm orders, conning the ship, effects of propellers on the steering of a ship, effects of wind and current, stopping, going astern, turning short round, interaction and squat, manoeuvring in the vicinity of pilot vessels and other craft, embarking and disembarking a pilot; ====

Response to Navigational Emergencies
==== a) initial action following: man overboard, collision, grounding, flooding or major mechanical damage, and receipt of a distress message; initial damage assessment and control, protection of the marine environment; ====
