IntroductionDemand 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 regionFor expanding their activities

Bangladesh is the most suitable place

History of Shipbuilding in Bangladesh

Between 15th and 17th century Bangladeshthe 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 shipyardEconomical & qualitative productions

Ensure the safe working environmentEnvironment friendly activities of the shipyard

Main purposes of the ship buildingTransfer goods, materials , animals etc

Safely, economically and timely Environment friendly ship operation

Considerations to meet the purpose of shipbuildingProper ship design & construction Proper ship operation

Initial steps for establishing shipyards

In shipyard activitiesHandling the most heavy materials & scraps Welding ,cutting, assembly and erection of large blocks

Important Factors Shipyard location & layoutWell trained workers for design and manufacturingMost important factor > strong govt. support and

dedication.

Huge opportunities:Good Geographical position

Good communication facilities Many inland shipping routesLow labor costMulti cultural countryFriendly working environment

Initial steps for establishing shipyards

Shipyard profitability initially depends onGood location is important (waterway & road tans.)

supplying raw materials to shipyarddelivery the ship

Well developed shipyard layoutProper placing of the departments is very important

For reducing the production time For reducing labour costs.Efficient management systems

Present production 2-3ships per yearIncrease 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 worksManual welding Manual plate (steel) cuttingManual transferring

plates & scraps

Shipbuilding industries in Bangladesh

Present conditionBuilding 100m length (Small medium size)

Most works doing Manually & risky

# Each shipyard per yearMajor & minor accidentsAbout 20-50

Where as in abroad About 2-5accidents

Even though huge prospers But not explore properlyLack of consciousness & knowledgeLack of technology

Shipbuilding industries in Bangladesh

That can reduce the quantity of the production.

Shipbuilding industries in Bangladesh

Assembling & storing the blocks getting any empty space.

During hull preparation for painting the wash water including

the removing marine growth on hull and old painthigh levels of heavy metals Contaminants with the nearby waters.

Paint stripping and painting activities are significant sources of pollution

Solvent-based paints including volatile organic compounds(VOCs), anti-fouling regulated hazardous

14

During repairing of old shipsWastages, sewage, oily thingsCoating of the hull, ballast and bilge water pollute marine environment

Environmental factors of Shipyard activities

Ship building

Ship designNeed highly skill employ (Naval Architect)

Ship constructionNeed Skill and medium skill employsMedium or non skill people are available in BD

Ship operationNeed Skill and medium skill employsMedium or non skill people are available in BD

For high speed ship wave resistance is very importantBy design optimization - required skill person.About 8% fuel consumption and emissions can be reduced.

For low speed ship frictional resistance is very importantSmoothing hull - required regular maintenance.About 3-4% fuel consumption and emissions reduced.

Which method is best in Bangladesh?

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

Which method is best in Bangladesh? Speed limit of Inland vessels in Bangladesh 6-12knots.

# Use available ship design in BDSaving the fuel consumption about 30%Reduced the accident about 60%# Regular hull maintenance in BDReduced the fuel consumption about 2-3%Emissions into air about 2-3% #Increased consciousness in BDReduced the accident about 20%

Ship accidents in Bangladesh

Most of the accident happened in BangladeshFor capsizing the vessels due to lack StabilityThe ship main hull required to be water tight But most of the inland vessels don’t have such hullUnskilled persons operate vessels

Stability analysis

Benefits of proper available design & hull maintenance

# Use available ship design in BDReduced fuel consumption & emissions about 40%Reduced the accident about 50% in operation

# Regular hull maintenance reducedThe fuel consumption about 4%Emissions into air about 4%Almost reduced the unexpected accidents

#Increased consciousness Reduced the accident about 40% in operationReduced the air and water pollution about 60%

Economical support

# Rumor →most of the old developed countriesShipping 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 marketAbout 0.5 million peoples

Directly involve with shipping and shipbuildingAlso indirectly

ConclusionHuge opportunities to expand ship building industries :

Good Geographical position & Low labor costTemporary expansion can be sustainable by >well trained people >Well developed infrastructures and production

The ship building industries can meet:Our own requirements including inland vesselsGrowing consciousness & proper steps(design, maintenance)>Almost accident can be prevent >Saving about 50% fuel consumption of inland vessels
