  • 1. Environmental dimension in a ship’s life cycle
    Presented by:
    Deepak Tiwari
    Nishant Pant
  • 2. What Is Product Life Cycle?
    The average life period of a particular product.
    How long a particular product will stay in the market.
    PLC of product is divided into 4 stages:
    Introduction
    Growth
    Maturity
    Decline

    Environmental Dimensions in Ships life Cycle
  • 7. Life Cycle Assessment (LCA)
    Used to identify, evaluate and minimize energy consumption and environmental impacts with respect to its life of the product.
    Sometimes called as “cradle-to-grave ” assessment.
    Provides better designs.
    Makes product cost effective.
    Helps provide environmentally sound products.
    Provides ideas for efficient waste mgmt. systems.

  • 8. Thus LCA is…..
    A systematic way of examining the environmental impacts of a product throughout its life cycle, from raw materials extraction through the processing, transport, use and finally product disposal.

    Environmental Dimensions in Ships life Cycle
  • 13. BASIC CONCEPT OF LCAAn environmental approach
    After scrapping, waste material needs to be disposed off.
    Special Considerations regarding
    Waste prevention.
    Waste minimization at source.
    Reuse, recover, repair, recycle.
    Incineration (burning with or without energy recovery)
    Landfill

  • 17. The main objectives of LCA are:
    Minimization of energy consumption
    Minimization of environmental impacts
    Rationalization of material used

    Environmental Dimensions in Ships life Cycle
  • 18. Main concepts of LCA of a product:
    Raw Materials
    Energy
    Product Life Cycle
    Rationalization
    Product Improvement
    Minimization
    Life cycle Assessment

  • 20. Inventory analysis
    Identification and calculation of energy and resources used and environmental releases to air, water and land for all the processes within the system boundary.
    The system boundaries includes :
    Main production sequence ,
    Handling and transport operations,
    Production and use of fuels, generation of energy (electricity and heat, including fuel production)
    Disposal of all process wastes

    Environmental Dimensions in Ships life Cycle
  • 21. Environmental impact assessment (EIA)
    Environmental impact assessment (EIA) is the technical qualitative and quantitative characterization and assessment of the consequences on the environment.
    The impact analysis addresses ecological and human health consequences and resource depletion.
    12/8/2009

    Environmental Dimensions in Ships life Cycle
  • 22. The main elements to be considered in an EIA
    Resources
    Human health
    Global warming
    Depletion of stratospheric ozone
    Acidification
    Habitat alterations and impacts on biological diversity
    Risk assessment

    Environmental Dimensions in Ships life Cycle
  • 23. Improvement analysis
    It is the evaluation and implementation of opportunities to reduce environmental burdens.
    This could be achieved by:
    The efficient use of natural and man-made materials and in a cost effective manner,
    Better measurement of environmental impacts,
    Minimization of consumption and management of wastes by recycling/reuse of waste as a raw material,
    Using clean technologies, polluting less, cleaning up the pollution,
    Using risk assessment and management.

    Environmental Dimensions in Ships life Cycle
  • 24. Cumulative energy and emission
    Ship building Stage
    Ship Operation Stage
    Ship Scrapping Stage
  • 25. LCA of ships
    LCA of Ship = rational use of material + outfitting material + energy consumption + environmental impact…this is applicable in all stages of the ship design till scrapping i.e.
    Design, construction.
    Outfitting, operation, maintenance & repair, &
    Finally in ship scrapping… …

    Environmental Dimensions in Ships life Cycle
  • 26. Environmental dimension in ship design…
    Integral part of rational approach to ship design.
    Also called ship design for environment (DFE).
    (safety, economy, energy efficiency, environmental performance and ship disposal)
    12/8/2009

    Environmental Dimensions in Ships life Cycle
  • 27. Rational use of materials…
    The main materials commonly used in the shipbuilding industry, which require rationalization, are:
    steel plates and sections,
    welding coils and rods,
    castings,
    forged parts,
    timber, paintings, etc.
    12/8/2009
    21
    Environmental Dimensions in Ships life Cycle
  • 28. The rational use of these materials should not only reduce energy consumption and the negative environmental impacts but should also have positive economic gains.
    The minimization of the negative environmental impacts and wastes in ship construction could be achieved by the efficient use of ship construction materials, welding rods, paints, etc.

    Environmental Dimensions in Ships life Cycle
  • 29. Environmental impact of shipproduction
    Energy used:
    Direct
    Indirect
    The indirect energy used in the shipbuilding industry is used for the manufacture and production of the following main items:
    steel plates and sections, main and auxiliary
    engines, equipment, fittings, welding coils
    The direct energy required for ship
    construction is used for handling and
    transport (raw materials, fabricated sections and blocks), fabrication processes (cutting, forming, welding), assembly of steel plates and sections.

  • 30. Environmental impacts of shipoperation
    Oceans are essential parts of the global life support system. They influence the climate and provide food and other resources for our growing world population. However, oceans are under increasing environmental stress from shipping operations.
    With regard to energy consumption, ships require less energy to carry a given tonnage of cargo over a given distance than all other means of transport.
    The environmental impacts of ship operation should be considered for both modes of operation at sea and in ports.
  • 31. Environmental Impact on ship operations.
  • 32. Environmental impact of shipscrapping
    Ship scrapping is becoming an important industry in several countries : -
    For ship owners, the decision to scrap a ship, continuing the operation or convert to a different trade requires condition assessment and economic evaluation.
    Because of the increasing costs of acquiring a new ship, some ship owners have extended the life of some of their ships by upgrading either hull, machinery or both. Extending a ship’s life is a positive attitude to protect our natural resources.
