What are the damage control actions on ship grounding?

What are the damage control actions on ship grounding?

Damage Control on Grounding Efforts have to be made to close the hole produced by the grounding, from inside the space being flooded. If the water ingress can be stopped or reduced temporarily, closing of the hole by some suitable materials can be attempted.

What are the actions taken in case of ship grounding?

Broadcast an URGENCY message to all ships in the vicinity and local coastguard or broadcast a DISTRESS ALERT if the ship is in a grave and imminent danger.

What will be the actions you should take when the ship has a damaged compartment and flooded at sea?

Following actions are to be taken immediately after damage in order to ensure the watertight integrity of the vessel and to assess the damage:

  • Closing of weather tight openings.
  • Closing of valves.
  • Check the extent of damage.
  • Sounding of flooded compartments.
  • Draught readings.

What are the factors affecting ship stability?

Stability overview Stability is determined by the force of buoyancy provided by the underwater parts of a vessel, coupled with the combined weight of its hull, equipment, fuel, stores and load. These forces can also be adversely affected by the prevailing weather conditions and sea-state.

What are the implications of stranding beaching and grounding to marine environment?

Ships that ground on coral reefs may cause immediate and long-term harm, and can destroy hundreds of years’ worth of coral growth. Oil and hazardous waste releases. Fuel, oil, and other chemicals might leak from the ship, and paint may be scraped from the hulls, causing injury to corals and other habitats.
