INTRODUCTUCTION
The grate majority of marine accidents are caused by collision and grounding attributable to human factors.
The paper will consider the human elements in navigational watch keeping on the ship's bridge to achieve safe navigation by supporting the advanced navigation systems, the human factors involved and the man/machine interfaces.
It is necessary to establish an efficient, safe and profitable operational system for the navigation and control of both ship owner and operator, so that they can be competitive in heir sea borne trade, taking into account the value of the property (ship & cargo), the need for international harmonization of rules and standards and the importance of environmental protection and conservation.
1. The needs
(OHP-1)
1.1 Safety:

Protecting the lives of crews
Protecting the ship owners' property
Safeguarding the worth of the cargo
Maintenance of sailing schedules
Establishing and maintaining the Trust of clients
Reducing insurance premiunms
Minimizing maintenance costs
1.2 Economy:
The systems for safety of navigation should be;
─ Economical in their contribution to the initial cost of the ship builder.
─ Be economical and efficient in their contribution to the total operational running costs of the ship.
─ Be economical in meeting the required constructional and operational “Rules”
