9 ENERGY AND ENVIRONMENT
The course on Energy and Environment should cover environmental and economic benefits resulting
from introducing methods of increasing efficiency of production processes, cost-effective methods of
handling unwanted eMuents and methods of waste reduction. The course should clearly indicate the
importance of using methods for energy conservation, raising energy efficiency in the various ship
production processes, energy saving techniques, minimization of total energy consumption.
minimization of wasted energy, controlling the environmental problems resulting from energy
consumption, using safer, cleaner and more efficient technologies and systems for ship production.
The course should also cover energy saving methods in ship operation, maintenance & repair and ship
scrapping.

10 WASTE MANAGEMENT

The course on Waste Management may include the environmental and economic benefits from life
extension. waste preventiodminimization at source, re-use, recycle, recover, repaidupgrade.
incineration, (witwwithout energy recovery), dumping and landfill.

Ship scrapping is becoming an important industry in several countries. The outcome of ship scrapping
includes usable materials, engines, equipment, fittings, etc. The various activities and operations used
in this industry should be rationalized so as to protect our natural resources, save energy consumption,
minimize environmental impacts and waste. The expected growth of this industry necessitates a
thorough examination of the main issues of energy and environment associated with this fast growing
industry. Waste management in ship scrapping should not only have significant economic
opportunities but should also have positive impact on environmental protection.

11 CONCLUSIONS

The main conclusions drawn up from this paper are:
In spite of the limited scale of local, regional and global negative environmental impacts of
shipbuilding and repair industries, the identification, quantification and control of these
negative impacts should receive serious attention.
LCA in the shipbuilding industry could bc used to assist shipbuilding and ship repair companies to
quantify, assess and identify opportunities to minimize energy consumption and its impact to the
environment, and to realize cost savings by making more effective use of available resources.
The rational use of shipbuilding materials should not only reduce the harmful environmental
impacts and energy consumption but should also have positive economic gains.
Waste management in ship scrapping should not only have significant economic opportunities
but should also have positive impact on natural resources and environmental protection.
The teaching of Design courses should be more comprehensive than that normally given in our
Faculties of Engineering and should cover the main issues of energy and environment.
The environmental dimension in ship design should be an integral part of a holistic approach of
ship design that takes account of safety, economy and environmental protection.
In order to improve local, regional end global environmental protection, future shipbuilding
and ship repair engineers should be well equipped with the necessary knowledge and tools
for energy conservation and environmental protection.
