1. TOPIC 4:
SHIPYARD PRACTICES

2. SHIPYARD Place where ships are repaired and built.
Demand of shipping transportation increasing
Creating pressure on shipbuilding industries
Place where ships are repaired and built.
Constructed nearby the sea or tidal rivers to allow easy access for the ships.
The site of large shipyard will contain many specialized cranes, dry dock, slipways, dust-free warehouse, painting facilities and extremely large areas for fabrication of the ships.

3. SHIPYARD AND SHIPBUILDING
Main Objectives of the shipyard
Economical 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

4. FACTORS ESTABLISHING SHIPYARDS
Huge opportunities:
Good Geographical position
Shipyard location & layout
Good communication facilities
Many inland shipping routes
Low labor cost
Friendly working environment
Well trained workers for design and manufacturing

5. Systematic Shipyard Layout (Flow of materials)

6. Present Condition of Shipyard Layout (Flow of materials)

7. SHIPBUILDING PROCESS Design Steel Cutting Block Assembly Painting
Block Erection
Launching & Outfitting
Sea trial & Delivery

8. Design Part Basic design Hull design Outfitting design
Basic modeling(Speed, loadage etc..)
Flow analysis
Hull design
Structure design
Structure & Fatigue strength analysis
Outfitting design
Pipe laying & Electrical wiring
Engine room design

9. Design Part ◈ Basic design
A basis modeling which taking a carrying capacity and speed
A performance assessment to a computer simulation.
And computer float analysis

10. Design Part ◈ Hull design
The design are firm to the iron board of the at least to the maximum and to develop fast speed.
Many simulation about the body of ship structure and computation need. 10

11. Design Part ◈ Outfitting design
A machinery and tools of the boiler room conduit install task.
install the cabin interior, the Electrical wire and pipe.
The place which resides at the vessel to charge the lodging equipment which members reside. 11

12. Steel Cutting Steel Cutting
The work that the steel place is automatically cut based upon production design in information

13. Steel Cutting Cutting Progress 1. Marking by NC machine
2. Marked steel

14. Steel Cutting Cutting Progress 1. 4. In order assembly pregress

15. Steel Cutting Cutting Equipment
Gas based cutter Major method, by oxygen- acetylene gas

16. Steel Cutting Cutting Equipment
Laser cutting Cutting that use molting, evaporation and high-handed gas It`s method that can cut 5~7mm steel for the present In oder to apply, need to more development than now

17. Block Assembly
Synthesis of Piece Assembly, Sub Assembly, Cutting/Bending and so on work that assemble area of ship hull space.

24. Block Erection
The process of building a ship afterwards the welding, after moving the blocks (which was made on the ground) by using the Gantry Crane. 24

25. PE : Pre-Erection PE : Pre-Erection
- PE is the process of making large before moving blocks to the dock. 25

26. Keel Laying & Lord Point
- The standard block in the Erection process
Lord point
- The connection point between the wires and the block. 26

29. Launching Major Methods 1. Slip-way launching 2. Float-out launching
3. Lift-on launching

30. Outfitting
Methods
Each mechanic part assembling & pipe laying & electronic equipment installing .

31. Sea trial & Delivery
< Sea trials >
Once the construction of the vessel is completed a sea trial is conducted in the presence of the ship’s owner register of shipping.

32. THE TEST LISTS OF SEA TRIAL ACCELERA-TION TEST
THE AMOUNT OF FUEL CONSUMED TEST
SPEED TEST
THE TEST LISTS OF SEA TRIAL
ACCELERA-TION TEST
TURNING TEST
STEERING TEST

33. < Naming ceremony >
Once the vessel is completed, it is named, and this naming process is called Naming ceremony.

34. Problems occur on shipbuilding industry
lack of infrastructures and equipment's facilities,
lack of skill workers and knowledge
improper governmental activities and dedication.
Lack of technology

35. ENVIRONMENTAL ASPECT
An environmental aspect is define as an element of facility’s activities, products or services that can or does interact with the environment.
An environmental impact is define as any change to the environment, whether adverse or beneficial, resulting from facility’s activities, products or services.

36. Environmental Impact(s)
Environmental Aspect
Environmental Impact(s)
Emissions of volatile organic
compounds (VOCs)
Air pollution, smog
Discharges to stream
Degradation of aquatic habitat and
drinking water supply
Spills and leaks
Soil and groundwater contamination
Electricity use
Air pollution, global warming
Use of recycled paper
Conservation of natural resources

37. 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
