Title: Important considerations


1
Important considerations contributions of
flourishing shipbuilding industries in Bangladesh
  • Khairul Hassan
  • Doctoral student
  • Maritime Engineering, Kyushu University, Japan

2
Overview
  • Introduction
  • History of shipbuilding in Bangladesh
  • Shipyards shipbuilding
  • Shipbuilding industries in Bangladesh and initial
    essential steps
  • Technology used in Shipyard
  • Essential steps in Ship design and ship operation
  • Contributions of the shipbuilding industries in
    Bangladesh
  • Conclusion

3
Introduction
  • Demand of shipping transportation increasing
  • Creating pressure on shipbuilding industries
  • Most of the shipyards are busy for production
  • Report on 2008
  • most of the shipyards are unable to make new
    contract by 2012.
  • About one third of the overall cost for labour
  • This industries are looking for cheap labour
    region
  • For expanding their activities
  • Bangladesh is the most suitable place

4
History of Shipbuilding in Bangladesh
  • Between 15th and 17th century Bangladesh
  • the centre for the building of ocean-going
    vessels in Asia
  • In the early 19th century the shipyards in
    Chittagong
  • built many commercial ships up to 1,000 tons
  • But this industry did not expand properly due to
  • lack of infrastructures and equipments
    facilities,
  • lack of skill workers and
  • improper governmental activities and dedication.

5
Shipyard shipbuilding
  • Main Objectives of the shipyard
  • Economical qualitative productions
  • Ensure the safe working environment
  • Environment friendly activities of the shipyard
  • Main purposes of the ship building
  • Transfer goods, materials , animals etc
  • Safely, economically and timely
  • Environment friendly ship operation
  • Considerations to meet the purpose of
    shipbuilding
  • Proper ship design construction
  • Proper ship operation

6
Initial steps for establishing shipyards
  • Huge opportunities
  • Good Geographical position
  • Good communication facilities
  • Many inland shipping routes
  • Low labor cost
  • Multi cultural country
  • Friendly working environment
  • In shipyard activities
  • Handling the most heavy materials scraps
  • Welding ,cutting, assembly and erection of large
    blocks
  • Important Factors
  • Shipyard location layout
  • Well trained workers for design and manufacturing
  • Most important factor gt strong govt. support and
    dedication.

7
Initial steps for establishing shipyards
  • Shipyard profitability initially depends on
  • Good location is important (waterway road
    tans.)
  • supplying raw materials to shipyard
  • delivery the ship
  • Well developed shipyard layout
  • Proper placing of the departments is very
    important
  • For reducing the production time
  • For reducing labour costs.
  • Efficient management systems
  • Present production 2-3ships per year
  • Increase about 20-30ships per year

8
Systematic Shipyard Layout(Flow of materials)
9
Present Condition of Shipyard Layout(Flow of
materials)
  • Still now there is no well developed systematic
    production line

10
Safety in a Shipyard
  • Most of the risky works
  • Manual welding
  • Manual plate (steel) cutting
  • Manual transferring
  • plates scraps

11
Shipbuilding industries in Bangladesh
  • Present condition
  • Building 100m length
  • (Small medium size)
  • Most works doing
  • Manually risky
  • Each shipyard per year
  • Major minor accidents
  • About 20-50
  • Where as in abroad
  • About 2-5accidents

12
Shipbuilding industries in Bangladesh
  • Even though huge prospers
  • But not explore properly
  • Lack of consciousness knowledge
  • Lack of technology

13
Shipbuilding industries in Bangladesh
  • Assembling storing the blocks getting any
    empty space.
  • That can reduce the quantity of the production.

14
Environmental factors of Shipyard activities
  • During hull preparation for painting the wash
    water including
  • the removing marine growth on hull and old paint
  • high levels of heavy metals
  • Contaminants with the nearby waters.
  • During repairing of old ships
  • Wastages, sewage, oily things
  • Coating of the hull, ballast and bilge water
  • pollute marine environment
  • Paint stripping and painting activities are
    significant sources of pollution
  • Solvent-based paints including volatile organic
    compounds(VOCs), anti-fouling regulated hazardous

15
Ship building
  • Ship design
  • Need highly skill employ (Naval Architect)
  • Ship construction
  • Need Skill and medium skill employs
  • Medium or non skill people are available in BD
  • Ship operation
  • Need Skill and medium skill employs
  • Medium or non skill people are available in BD

16
Which method is best in Bangladesh?
  • For high speed ship wave resistance is very
    important
  • By design optimization - required skill person.
  • About 8 fuel consumption and emissions can be
    reduced.
  • For low speed ship frictional resistance is very
    important
  • Smoothing hull - required regular maintenance.
  • About 3-4 fuel consumption and emissions
    reduced.

17
Which method is best in Bangladesh?
  • Speed limit of Inland vessels in Bangladesh
    6-12knots.
  • In Bangladesh for power reduction
  • frictional resistance reduction most applicable
    method.
  • In Bangladesh difficulties
  • Reluctant to grow up consciousnesses.
  • Lack of consciousness
  • lack of knowledge
  • Use available ship design in BD
  • Saving the fuel consumption about 30
  • Reduced the accident about 60
  • Regular hull maintenance in BD
  • Reduced the fuel consumption about 2-3
  • Emissions into air about 2-3
  • Increased consciousness in BD
  • Reduced the accident about 20

18
Ship accidents in Bangladesh
  • Most of the accident happened in Bangladesh
  • For capsizing the vessels due to lack Stability
  • The ship main hull required to be water tight
  • But most of the inland vessels dont have such
    hull
  • Unskilled persons operate vessels
  • Stability
  • analysis

19
Benefits of proper available design hull
maintenance
  • Use available ship design in BD
  • Reduced fuel consumption emissions about 40
  • Reduced the accident about 50 in operation
  • Regular hull maintenance reduced
  • The fuel consumption about 4
  • Emissions into air about 4
  • Almost reduced the unexpected accidents
  • Increased consciousness
  • Reduced the accident about 40 in operation
  • Reduced the air and water pollution about 60

20
Economical support
  • Rumor ?most of the old developed countries
  • Shipping and ship buildings gtbehind of
    development
  • At the present situation most shipyards are busy
  • Bangladesh has a opportunity to get the new
    orders
  • Good starting and well developed
    infrastructures
  • gtGive permanent expansion in BD
  • Explore the new opportunity, new job market
  • About 0.5 million peoples
  • Directly involve with shipping and shipbuilding
  • Also indirectly

21
Conclusion
  • Huge opportunities to expand ship building
    industries
  • Good Geographical position Low labor cost
  • Temporary expansion can be sustainable by
  • gtwell trained people
  • gtWell developed infrastructures and production
  • The ship building industries can meet
  • Our own requirements including inland vessels
  • Growing consciousness proper steps(design,
    maintenance)
  • gtAlmost accident can be prevent
  • gtSaving about 50 fuel consumption of inland
    vessels
