The damage control plan and damage control booklet, which are required by SOLAS regulation II 1/19, are intended to provide ships’ officers with clear information on the ship’s watertight subdivision and equipment related to maintaining the boundaries and effectiveness of the subdivision so that, in the event of damage
What is intact and damage stability
INTACT STABILITY ANALYSIS
Intact stability is the basic and utmost check for ship’s sea worthiness and very important when ship is not damaged. We have done intact stability using various codes and regulation.
How is damage stability of a ship calculated
In this process, the ship is divided into several subdivisions along its length with the help of transverse watertight bulkheads. Now the stability of the ship is calculated when one or more compartments get flooded due to a breach of hull.
What is damage stability for passenger ships
Passenger ships – Longitudinal extent of damage; 3m + 3% of L or, 11m whichever is least. Where the required factor of subdivision is 0.33 or less the longitudinal extent must be increased to include flooding of any three consecutive compartments.
What is damage stability as per SOLAS
A damage stability criterion varies from ship to ship and the requirement for the same is given in SOLAS chapter II-1. It may be single compartment flooding, multi compartment flooding, engine room flooding etc. Under all the criteria as applicable, vessel margin line should not be submerged after the damage.
What are the 3 basic objectives of damage control?
Prevent further damage (damage control). Offer authoritative, effective crisis leadership. Provide psychological support.
What are the 2 basic types of stability
- Stable equilibrium.
- Unstable equilibrium.
What are types of stability
- Freeze and Thaw Stability;
- Bench-Top Stability;
- Long-Term Stability;
- Stock Solution Stability;
- Processed Sample Stability;
- Auto-sampler Stability.
What is meant by intact stability
Intact stability
The vessel is in normal operational configuration. The hull is not breached in any compartment. The vessel will be expected to meet various stability criteria such as GMt (metacentric height), area under the GZ (righting lever) curve, range of stability, trim, etc.
What are the 3 types of ship stability condition
- GM > 0 means the ship is stable.
- GM = 0 means the ship is neutrally stable.
- GM < 0 means the ship is unstable.
What is GZ in ship stability
The vessel’s centre of gravity (G) has a distinct effect on the righting lever (GZ) and consequently the ability of a vessel to return to the upright position. The lower the centre of gravity (G), the bigger is the righting lever (GZ).
How do you calculate expected damage
Expected Annual Damages (EAD)
The total damages for each event is then multiplied by the event probability to provide the annual damage. This is then summed for all return periods to provide the Expected Annual Damage for all events.
Who is responsible for ship stability?
Chief mate: The head of the deck department on a merchant vessel, second-in-command after the ship’s Master. This position is responsible for cargo operations, the vessel’s stability, the deck crew and the safety and security of the vessel.
What information is in a damage control plan
Damage control plan gives the location and details of the air pipes of all compartments. It gives the location and details of all watertight (and weather tights) doors on the ship. Similarly, damage control plan gives the details of Tanks, Hatches or other compartments on ships.
What is meant by damage control
noun. : measures taken to offset or minimize damage to reputation, credibility, or public image caused by a controversial act, remark, or revelation.6 days ago
What is damage control in maritime
In navies and the maritime industry, damage control is the emergency control of situations that may cause the sinking of a watercraft.
What is basic ship stability
Ship stability is an area of naval architecture and ship design that deals with how a ship behaves at sea, both in still water and in waves, whether intact or damaged. Stability calculations focus on centers of gravity, centers of buoyancy, the metacenters of vessels, and on how these interact.
What are the principles of damage control
Damage control involves three phases: control of life-threatening hemorrhage and contamination followed by more complete resuscitation and correction of physiologic derangements, usually in the intensive care unit. The last phase is the definitive management of injuries [1].
What are the steps in damage control
Twenty years ago, damage control surgery (DCS) was implemented to challenge the coagulopathy of trauma. It consists of three steps: abbreviated surgery to control the hemorrhage and contamination, resuscitation in the intensive care unit (ICU), and planned re-operation with definitive surgery.
What are the 4 factors of stability
Common factors that affect this stability include temperature, light, pH, oxidation and enzymatic degradation.
What is an example of a stability
In science and engineering, stability denotes a system that is in equilibrium that is able to return to equilibrium when disturbed. For example, a building that stands upward resisting the forces of gravity is in equilibrium.
What is the concept of stability?
: the quality, state, or degree of being stable: such as. : the strength to stand or endure : firmness. : the property of a body that causes it when disturbed from a condition of equilibrium or steady motion to develop forces or moments that restore the original condition.
What is physical stability
The authors of this Stimuli article define physical stability to be as follows: “Physical stability is the ability of a material to remain physically unchanged over time under stated or reasonably-expected conditions for manufacturing, storage and use”.
How can you improve stability
- Walking, biking, and climbing stairs strengthen muscles in your lower body.
- Stretching loosens tight muscles, which can affect posture and balance.
- Yoga strengthens and stretches tight muscles while challenging your static and dynamic balance skills.
What are the conditions for stability
The stability condition of a system in its final state is where all the links are | xij | ≈ 1 and xij dxij/dt > 0; either xij increases to 1 or it decreases to − 1. Fig. 5 represents a jammed state, where positive links are within a triad, and negative links are between different triads.
What is intact stability and dynamic stability
However, dynamic stability deals with the study of stability over a range of angle of heels on the curve of intact stability. For any given angle of heel, dynamic stability is the measure of the work done in heeling the ship to that angle, very slowly and while maintaining constant displacement.
What is stability of a vessel?
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.
