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:

Life Cycle Assessment

(LCA)Used to identify, evaluate and minimize energyconsumption and environmental impacts withrespect 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.



Thus LCA is..

A systematic way of examining theenvironmental impacts of a productthroughout its life cycle, from raw materials

extraction through the processing,

transport, use and finally product disposal.

LCA are:

Minimization of energy consumption

Minimization of environmental impacts

Rationalization of material used

Inventory analysisIdentification and calculation of energy andresources used and environmental releasesto 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 ofenergy (electricity and heat, including fuel

production)

Disposal of all process wastes

Environmental impact

assessment (EIA)Environmental impact assessment (EIA) is thetechnical qualitative and quantitativecharacterization and assessment of the

consequences on the environment.The impact analysis addresses ecological and

human health consequences and resourcedepletion.

Improvement analysisIt is the evaluation and implementation ofopportunities to reduce environmentalburdens.

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 andmanagement of wastes by recycling/reuse ofwaste as a raw material,

Using clean technologies, polluting less,

cleaning up the pollution,

Environmental dimension in

ship designIntegral part of rational approach to ship

design.

Also called ship design for environment (DFE).(safety, economy, energy efficiency,

environmental performance and ship disposal)


21/27


Rational use ofmaterialsThe main materials commonly used in the

shipbuilding industry, which requirerationalization, are:

steel plates and sections,

welding coils and rods,

castings,

forged parts,

timber, paintings, etc.


22/27


The rational use of thesematerials should not

only reduce energyconsumption and thenegative environmentalimpacts but should alsohave positive economic

gains.

The minimization of the

negative environmentalimpacts and wastes inship construction couldbe achieved by theefficient use of shipconstruction materials,welding rods, paints,

etc.

operationOceans are essential parts of the global lifesupport system. They influence the climateand provide food and other resources for our

growing world population. However, oceansare under increasing environmental stressfrom shipping operations.

With regard to energy consumption, shipsrequire less energy to carry a given tonnageof cargo over a given distance than all othermeans of transport.

The environmental impacts of ship operationshould be considered for both modes of

operation at sea and in ports.

scrappingShip scrapping is becoming an importantindustry in several countries : -

For ship owners, the decision to scrap a ship,

continuing the operation or convert to adifferent trade requires condition assessmentand economic evaluation.

Because of the increasing costs of acquiring a

new ship, some ship owners have extendedthe life of some of their ships by upgradingeither hull, machinery or both. Extending aships life is a positive attitude to protect ournatural resources.
