Important considerations & contributions of flourishing shipbuilding industries in Bangladesh

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. 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. Introduction • 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 > 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 don’t 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 >behind 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 • >Give 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 • >well trained people • >Well developed infrastructures and production • The ship building industries can meet: • Our own requirements including inland vessels • Growing consciousness & proper steps(design, maintenance) • >Almost accident can be prevent • >Saving about 50% fuel consumption of inland vessels
