Technology used in Shipyard
Essential steps in Ship design and ship operation
Contributions of the shipbuilding industries in Bangladesh
Conclusion
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
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.
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
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.
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
Systematic Shipyard Layout
(Flow of materials)
Present Condition of Shipyard Layout
(Flow of materials)
Still now there is no well developed systematic production line
Safety in a Shipyard
Most of the risky works
Manual welding
Manual plate (steel) cutting
Manual transferring
plates & scraps
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
Shipbuilding industries in Bangladesh
Even though huge prospers
But not explore properly
Lack of consciousness & knowledge
Lack of technology
Shipbuilding industries in Bangladesh
Assembling & storing
the blocks getting any
empty space.
That can reduce the
quantity
of
the
production.
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

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
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.
Resistance coefficients
For low speed ship frictional resistance is very important
Smoothing hull - required regular maintenance.
About 3-4% fuel consumption and emissions reduced.

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%
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
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%
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
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
