3. BACKGROUND OF THE STUDY
Like land-based industrial power systems,
increasingly of the generated power is fed
on with the aid of using electronic
equipment on the ship.
§ To minimize the electrical accident on
board ship
§ To develop a safe electrical working
environment on board ship

4. PROBLEM STATEMENT
Electrical work done during the development of
vessels includes the establishment of conductive
links, wires, circuit boards, and hardware, which
eventually should be enacted.
There have been incidents where failure to use
safe isolation procedures has resulted in needless
loose of life. If the correct procedure is not
followed and safe equipment is not used, then it
results in the serious injury of operating
personnel.

5. OBJECTIVE OF THE STUDY
§ provide a comprehensive review of the implementation
of safe electrical isolation procedures
§ determine the importance & essence of a safe working
environment.
§ Illustrate the current status of specific legislative duties
§ Identify how to make sure the workplace strictly
follows isolation procedures.
§ Find reasons for its slow adoption by identifying the
cause.
§ Identify how to provide information, instruction and
training to workers

6. OVERVIEW OF
ELECTRICAL
ISOLATION
Electrical isolation means that the
machine/equipment or circuit has
been deliberately disconnected from
the electricity supply and precautions
taken to prevent reconnection.
Isolation of
equipment from the
Electricity Supply
§ Identify fuse or
circuit breaker need
to be turned off
§ Ensure no exposed
terminals
§ Test isolation is
effective using Prove
– Test - Prove
§ Secure the isolation

18. SUMMARY OF RESEARCH FINDINGS
Companies should provide proper physical and mental
health support for the seafarers on board
Human error and lack of knowledge or deficiency in skill
are the main reasons behind the shipboard electrical
accidents
Usage of a safe electrical system onboard ships can
reduce the shipping accidents
Keep available user manuals for every equipment of ship and
need to maintain proper risk assessment
Most of the time, accidents occur due to fatigue, mental
and emotional health condition of the working personnel
As this study is one of the first studies on this topic in
Bangladeshi maritime society, this paper is recommended to be
consulted for further research on this topic.

19. ESSENTIAL LIST WHILE WORKING
ONBOARD
NEED TO DO ON SHIP-
§ Know the ship’s electrical system and equipment
§ Write down the information on a note book
§ Become familiar with the normal indication on switchboard instruments
§ Operate equipment according to manufacturer’s recommendations
§ Ensure all guards, covers and doors are securely fitted
§ Switch off and lock off supplies, remove fuses and display warning notice
before commencing maintenance work
§ Before touching conductors and terminals confirm circuits are dead
DO NOT-
§ Touch live conductors under any pretext
§ Touch rotating parts
§ Overload equipment
§ Neglect equipment

20. CONCLUSION
To find out the real scenario of
electrical isolation procedures on
board ship
Conducted for the scope to support
the implementation of electrical
isolation procedures in the
merchant's vessels
To realize the importance of a safe
working environment to eliminate
shipboard electrical accidents

21. RECOMMENDATION
Several shipboard tasks can be included
familiarization with the correct procedure
Nominating fit and appropriately trained
person
co-operation between the companies and
ship personnel

22. RECOMMENDATION
IMO may amend the existing regulation
Follow the guidance of the shipping
company
STCW may set standards of training
facilities
introduction of a new policy to get
maximum benefits from implementation
