Habour and dock engineering

  1. 1.  PRESENTATION TOPIC: HARBOUR DOCK ENGINEERING GROUP MEMBERS: KASHIF ALI KHAN IZHAR AHMAD SEYED BAKTH JAMAL SHAH
  2. 2. HARBOUR: › SHELTERED AREA › FOR LOADING AND UNLOADING OF CARGO › VESSELS ARE ALSO BUILT, REPAIR, AND LAUNCH
  3. 3.  CLASSIFICATION: 1. NATURAL HARBOUR 2. SEMI NATURAL HARBOUR 3. ARTIFICIAL HARBOUR
  4. 4.  NATURAL HARBOURS: A harbor, is a place where ships, boats, and barges can seek shelter from stormy weather.
  5. 5.  SEMI NATURAL HARBOUR: Same as natural but harbour needs some artificial and man made construction
  6. 6.  ARTIFICIAL HARBOUR: Harbour having no natural protection but artificial arrangement are made to protect the harbour from storm and wind.
  7. 7.  REQUIREMENTS OF A GOOD HARBOR: › The depth of a harbor should be sufficient for every type of visiting ships. › The bottom of harbor should provide secured anchorage to hold the ships against high winds. › To prevent destructive wave action, break water are provided. › The entrance of a harbor should be wide enough to provide the easy passage of ships.
  8. 8.  DEFECTS IN HARBOR: › Depth of water is found insufficient for different ships. › The size of harbor is found insufficient to accommodate the increased traffic. › Obstruction › These defects can easily be avoided at the time of planning and designing.
  9. 9. SIZE OF A HARBOUR Size depends upon: # of ships  length:275m-300m  width:30m
  10. 10.  HARBOUR PLANNING It should be carried out after collecting necessary information of the existing features at the proposed site. Following important facts should be studied.
  11. 11.  A thorough survey of the neighborhood including the foreshore & depths of water is necessary Nature of a harbor wether sheltered or not, be studied The existance of sea insects & various animals residing at site.
  12. 12.  Natural phenomena’s concerning planning of a harbour are: Storms Rainfall Range of tides Maximum & minimum temperatures Direction & intensity of wind etc
  13. 13.  SITE SELECTION: Following factors play a great role in the choice of site of a harbour. 1.Availability of cheap land & contruction material. 2.Natural protection from waves & winds 3.transport & communication facilities 4.industrial development of the locality
  14. 14.  5.Sea bed,sub soil & foundation conditions 6.Avaibility of electrical energy 7.Defence & strategic aspects 8.trafic potentiality of harbour
  15. 15.  FUNCTIONAL CLASSIFICATION: 1. HARBOR OF REFUGE 2. COMMERCIAL HARBOR 3. FISHRY HARBOR 4. MILLITARY HARBOR OR NAVEL BASE
  16. 16.  HARBOR OF REFUGE: The harbor used for ships in storms or emergency condition. good anchorage and safe and easy access from the sea. e.g: DOVER IN ENGLAND
  17. 17.  COMMERCIAL HARBOR: Facilities for loading and unloading of cargo are provided. The may be: 1. Part of bigger complex harbor 2. Independent unit or single commodity harbor. 3. Terminal as oil terminal, coal port.
  18. 18.  FISHRY HARBOR: Provided for fishing crafts and trawlers.
  19. 19.  MILLITARY HARBOR: This harbor is meant for accommodating naval crafts and serves as a supply deport. The layout of this type of harbor is greatly influenced by its location.
  20. 20.  FEATURES OF A HARBOR: 1. Entrance Channels 2. Berthing Basin 3. Break Water 4. Turning Basin 5. Pier Head 6. Wharves 7. Jetties
  21. 21.  ENTRANCE CHANNEL: › Depth and width are kept more at entrance › Width depends upon density of traffic and no: of entrances
  22. 22.  BERTHING AND TURNING BASINS: › Berthing basins are used for the parking of ships › While turning for the turning of ships
  23. 23.  BREAK WATER: › The structure constructed to protect harbor from storm waves › They are generally stone masonry
  24. 24.  PIER HEAD: › The structure provided at the tip of break water › Such as light house
  25. 25.  WHARVES: › The structure constructed parallel to the shore or break water, having wide plate form at the top › Function is to permit berthing of vessel along side for cargo working
  26. 26.  JETTIES: › Same as wharves › Used for loading and unloading of cargo › Made usually from shore towards sea water to prevent silting and dredging to allow free flow of tidal currents
  27. 27.  DOCK: › A dock is dug out and usually has gates so that the water level is kept up even though the tide has gone out. › A dock is for mooring ships for cargo or passenger exchange, or sometimes repair.
  28. 28.  HARBOR: › A harbour may be natural or partly dug out, or even made with floating materials. It doesnt have gates, but may have a narrow entrance. › Provides safe anchoring or mooring for ships
  29. 29.  PORTS: › A port is a location on a coast or shore containing one or more harbors where ships can dock and transfer people or cargo to or from land.
