seaworthiness Flashcards
Define seaworthiness
Seaworthiness is whether a ship is safe to set out on a voyage and deal with the perils of the sea.
Define watertight integrity
Watertight means having scantlings and arrangements capable of preventing the passage of
water in any direction under the head of water likely to occur in intact and damaged
conditions.
• Preparations for sea prior to sailing with respect to watertight integrity
- Check the weather forecast is acceptable.
- Check the passage plan is suitable with regard to the strength of the vessel.
- Stability book ready and we are in an acceptable condition.
- Hatchways are shut.
- Watertight doors closed.
- Opening of the ships side below the freeboard deck.
- Deadlights fitted.
- Storm shutters fitted.
- Freeing ports Scuppers water freeing arrangements.
- Ventilators and air pipes.
- Load lines markings.
- Ensure the vessel complies with the condition of assignment.
- Jacuzzi swimming pools drained and open.
- Tenders secured etc.
• Fill out the OLB.
• We are going to check our load line certificate and markings comply and post form
FRE13.
Action in the event of ingress of water into the hullActions on finding water would include:
- Maneuver own vessel to reduce water ingress key part to survival.
- Close all water tight doors.
- Sound general alarms.
- Muster crew and passengers with lifejackets.
- Switch on deck lighting.
- Investigate damage and initiate control measures including environmental impact.
- Determine vessel position and depth of water.
- Determine weather/wind is carrying the vessel into danger and consider anchoring.
- Check stability book for damage stability.
- Update Coastguard urgency or distress.
- Record all details in the deck logbook and elsewhere as required.
- Consider Abandoning ship.
• Precautions to be taken prior to the onset of heavy weather
Precautions to be taken prior to the onset of heavy weather, management of small ships in heavy weather, and handling a disabled ship
Master specific are:
Navigation and bad weather
* Consider re-routing.
* Find a lee shore. (this is referenced from the lands point of view ie seek shelter)
* Verify the vessel position.
* Update weather report.
* Plot storm position often.
* Engage manual steering.
* Reduce speed.
Crew and passengers
* Make a public announcement to stop all work on deck and restrict access.
* Warn all departments to secure their work area.
* Re-arrange working hours to ensure adequate bridge cover.
Vessel specific
* Check stability and ballast down.
* Check deck lights.
* Engine checks.
* Steering checks before bad weather.
* If at anchor go to sea.
* If in port go to sea.
* Be prepared to go to hand steering.
* Have searchlights on and facing forwards.
* Update your location to all vessels in immediate area.
* Remove all loose gear from decks.
• Be ready to alter course and speed to make reduce risk of broaching, pooping damage
to hull or superstructure.
- Use and care of deck machinery commonly fitted
The various items of machinery and equipment found outside of the machinery space of a superyacht. These include deck machinery such as:
* Tenders.
* Mooring equipment.
* Anchor handling equipment.
* Rescue boat.
* Liferafts.
* Watertight doors.
* Stabilisers.
* Bow thrusters.
It is essential that deck machinery should require minimum maintenance. Totally enclosed equipment with oil bath lubrication for gears and bearings is now standard but maintenance cannot be completely eliminated and routine checking and greasing should be carried out on a planned basis.
Operate deck machinery
* Pre-operational checks of deck machinery and associated systems are carried out in accordance with safety requirements and shipboard practices.
* Operation of deck machinery is performed in accordance with manufacturer’s specifications and instructions and safety requirements.
* Any operational problems encountered in the use of deck machinery on the vessel are reported and/or rectified in accordance with procedures.
* Malfunctioning equipment is identified, and the nature of the fault is investigated and the outcomes reported in accordance with procedures.
* Post-operational checks of deck machinery and associated systems are carried out in accordance with safety requirements and shipboard practices.
* Records of equipment status and identified defects and malfunctions are completed in accordance with procedures.
Carry out routine planned maintenance of deck machinery
* • Planned maintenance is carried out as per SMS or IDEA style system •
Apply safety and hazard control procedures
• Safety, hazard minimisation and pollution control procedures and regulations are followed at all times during the operation of deck machinery
