International Safety Management

- Oil tankers - Discharge permitted in all waters if more than 50nm from land, en route, discharge rate less than 30lt per nm, and total discharge does not exceed the regulation % of cargo.

- All vessels > or = to 400 gross ton - Discharge permitted in all waters except special areas when, en route and <15ppm, and oil control and discharge sytem equipment is operating

- All vessels < 400 gross ton - Oil and oily mixtures retained on board for shorr disposal. Or - Discharge permitted in all waters except special areas whilst enroute, and approved operational equipment at 15ppm of oil pumped over board.

- Food under 1 inch, not in special areas

- Annex 1 - Oils

- Annex 1 - Sewerage

- Annex 1 - Garbage

Restricted to plant capabilities

- Untreated - greater than 12nm

- Comminutted and disinfected - more than 3nm

- IMO plant - anywhere

Shipboard Oil Pollution Emergency Plan

- Prevent oil pollution

- Stop or minimise oil outflow when damage to the ship occurs or the requirements when this occurs

- Stop or minimise oil outflow when an operational spill occurs in excess of the quantity or;

- Instantaneous rate permitted under the present Convention

MARPOL Annex V

- No discharge of plastics anywhere

- Food scraps processed throug the galley disposal unit (greater than 25mm) cannot be discharged within 3nm

- Discharge permitted, while en route, as far as paractible from the nearest land, but in any case, greater than or equal to 12nm from the nearest land not within a special area.

- On coastal voyages, with short runs between ports, garbage should be retained on board for disposal to shore facilities in port. And stowed correctly in the vessels bins.

- Engineroom waste should be keept seperate to other garbage as it may require disposal at a different location.

- Designated person in charge of carrying out the plan

- Procedures for collecting garbage

- Procedure for processing garbage

- Procedure for storing garbage

- Procedure for disposing of garbage

MARPOL Annex IV

Due to the specific gravity of different oils

MARPOL Annex VI

- Survival of life at sea - SOLAS

- Marine pollution - MARPOL

- Standards of training, certification of Watchkeeping for seafarers -STCW

- International safety management code - ISM

- The saftey of ships and their crews

- Prevention of pollution of the environment by shipping

Authorises certian clasification societies to act on it's behalf in the surveying and certification of ships?

Fishing vessels or vessels less than 24 metres in lenghth.

- Increases the range of stability when the ship is rolling

- Helps prevent water coming on board

- Provides a reserve of buoyancy

- Avoids excessive stress on the ships hull due to overloading

To ensure the safe operation and conduct of all vessels with the primary emphasis on the safety of life. The contravention sets international guidelines for the construction, equipment, operation, and navigation of sea going vessels.

Explains the general provisions of the convention, among which are the surveys which are required and the certificates which are issued to show a vessel complies with the regulations.

Is concerned with the ships subdivision and stability, machinery and electrical installation.

Is concerend with fire aboard a ship.

Is concerned withthe provision and operation of lifesaving appliances.

Deals with the management of the safe operation of ships.

Is the advent know as high speed craft.

- Non-essential gear is removed

- Copy of dry docking plan to dock superintendent

- Work plan ready for vessel staff

- Contractor work plan submitted

- Ensure surveyors are informed

- Rudders ans stabilisers, or retractable propulsion units are in docking position

- Access to vessel has been arranged

- Copies of the vessels fire plan ready, and fire prevention control equipment is in good order.

- Shore supply of fire main has been arranged

- Electrical supply has been arranged

- Vessel liquid state

Power is the measure of how much work can be done in a given amount of time.

- P = V I

An AVR maintains generator voltage output to a specific value by increasing/decreasing the stator excitation field during load fluctuations

1. Assess the situation - reason for the isolation - ability to conduct the isolation

2. Notification - notify all the affected people and gain authority to conduct isolation

3. Determine the meathod of isolating supply:

- Alternate supply

- Stored energy devices

- Heater and control circuits

4. Test - test equipment and supply voltage at consumer, double checking isolation

5. Isolation - isolate supply

6. Lockout device - lockout supply and tag it

7. Test supply for dead and test tester against know source

Short Term Exposure Limit

- the acceptable average exposure over a short period of time. Less than 15min, 60min between, no more than 4 hours a day

Time Weighted Average

- The average exposure over a specified period, usually a nominal 8 hours, 5 days a week

Threshold Value Limit or Threshold Limit Value

- The maximum average concentration of a hazardous substance/chemical to which a worker can be exposed to day after day for a working lifetime without adverse affects.

Odour Threshold

- Smell limit

Potential of Hydrogen

- Acid to Alkaline scale

- Acid = 1, Neutral = 7, Alkaline = 14

Leathal Dosage to 50% test population

Immediately Dangerous to Life and Health

Lower Flamable Limit

- Percentage of concentration allowed in an atmosphere before being flamable

- Free surface effect is the change in stability of a vessel caused by liquids moving about freely in a tank or hold. Free surface effect cause a loss in metacentric height. Virtural rise in G.

- We manage it by:

- Pumping overboard

- Pump down to lower compartments

- Draining the liquid down in the vessel

- Press or completely fill the compartment

- Break up/baffle, cofferdams - interim meathod

- Jettison top weight - last resort

It is the ratio of the density of a substance to the density of a reference substance.

Generally 0.81 - 0.86, but sometimes up to 0.92

0.86 - 0.92

- Under/over voltage

- Under/over frequency

- Phase rotation

- Current overload

- Stator earth faults

- Thermal protection
