  • 1. Friday 13, 2010.
  • 2. SAFETY ?????
    • During the last two decades, accidents caused by different factors has called the attention from the maritime world. That´s why, after a few maritime disasters people and companies related to this arena, have focused their attention on the causes of these accidents in order to avoid them and this has resulted in a great emphasis on safety in navigation.

  • 3. Objectives
    • General Objectives:
    • To give students wide-ranging opportunities to practice communicating in English for both, maritime and general purposes.
    • Specific Objectives:
    • To describe weather conditions and understand forecasts.
    • To identify various incidents at sea.
    • To demonstrate understanding of safety factors in order to avoid accidents at sea.
    Edilma C. de Llorente
  • 4. The Weather
    • It´s determined by various meteorological elements .
    • Temperature
    • Humidity
    • Cloudiness
    • Fog
    • Precipitation
    • Wind
    Edilma C. de Llorente
  • 5. But...what is the weather?
    • The weather is the condition of the atmosphere at any particular time and place.
    • The meterological elements such as temperature, humidity, cloudiness, fog and wind, may be referred to as the weather.
    Edilma C. de Llorente
  • 6. Meteorological Elements
      • Scientifically use Kelvin-scale .
      • Commonly uses Celsius-scale.
      • Obsolete Fahrenheit-scale.
      • Amount of water vapor in the air.
      • Maximum a mount of moisture is known as saturation.
    Edilma C. de Llorente
  • 7. Meteorological Elements
      • Indicates a imminent changes of weather.
      • Types of clouds: cirrus, stratus and cumulus.
    • FOG:
      • Cloud that touches the ground.
      • Dense fog are referred as thick weather.
    Edilma C. de Llorente
  • 8. Meteorological Elements
      • Formed when the droplets has become sufficiently large to fall to the ground.
    • WIND:
      • Most important factor.
      • Determined the condition of weather.
    Edilma C. de Llorente
  • 9. The atmospheric Pressure
    • It is measured by the height of a column of mercury or with an aneroid barometer.
    • The average atmospheric pressure at sea level in millibars is 1.013 in winter and 1.016 in summer.
    Edilma C. de Llorente
  • 10. The Weather Systems
    • There are two main weather systems in the general weather patterns:
    • The anticyclones and,
    • The depressions or cyclones.
    Edilma C. de Llorente
  • 11. Anticyclones
    • A High-Pressure Area
    • In the northern hemisphere an anticyclone is a system of wind wich circulates spirally in a clockwise direction around an area of high pressure.
    • In the southern hemisphere anticyclonic wind circulates in an anti-clockwise direction, thoug still around a high pressure area.
    Edilma C. de Llorente
  • 12. Depressions or Cyclones A Low Pressure Area
    • In a bad-weather system, the wind blows in an anti-clockwise direction about a centre of low pressure in the northern hemisphere; and in a clockwise direction in the southern hemisphere.
    Edilma C. de Llorente
  • 13. Tropical Cyclones Edilma C. de Llorente
  • 14. The Beaufort-scale
    • Wind forces are indicated by the Beaufort-scale used for describing wind speed based mainly on observed sea conditions.
    • These numbers, ranging from zero (calm) to force 12 (storm), and it refers to the wind speed measured in nautical miles per hour.
    Edilma C. de Llorente
  • 15. Edilma C. de Llorente
  • 16.
    • Application of the Beaufort Scale
    Edilma C. de Llorente
  • 17. Calm Storm EXAMPLES Edilma C. de Llorente
  • 18. Maritime Accidents
    • These maritime accidents have consecuences such as:
    Catastrophic consecuences Major consecuences Edilma C. de Llorente
  • 19. Maritime Accidents Moderate consecuences Minor consecuences Edilma C. de Llorente
  • 20. Types of Accidents Sinking Collision Grounding Fire Environmental Pollution Edilma C. de Llorente
  • 21. Safety factors
    • Internal Factors
    • External Factors
    • Human Factors
    Edilma C. de Llorente
  • 22. DON´T FORGET…...
    • To be safety at sea, is of great importance to navigators to follow these steps:
    • Do a voyage planning before leaving the port
    • Evaluate the weather conditions of the area you´ll be travelling through.
    • Work as a team while at sea.
    • Take into consideration all the safety factors you need to follow in order to be safety at sea.
