A Handy Summary

This series of posts on SOLAS V, Safety of navigation now explores a group of regulations concerned with the navigational bridge. 

What Regulation covers Navigational Bridge Design?

SOLAS Regulation 15 – ‘Principles Relating to Bridge Design, Design and Arrangement of Navigational Systems and Equipment and Bridge Procedures.‘ The principles in this Regulation must be taken into account when complying with the following SOLAS regulations:

  • 19-Carriage requirements for shipborne navigational systems and equipment
  • 22-Navigation bridge visibility
  • 24-Use of heading and/or track control systems
  • 25-Operation of main source of electrical power and steering gear
  • 27-Nautical charts and nautical publications
  • 28-Records of navigational activities and daily reporting

These regulations will be covered in later posts.

Bridge design must:

Appraisal-Facilitate the tasks to be performed by the bridge team and the pilot in making full appraisal of the situation and in navigating the ship safely under all  conditions.

Bridge Resources-Promote effective and safe bridge resource management.

Information access-Enable the bridge team and the pilot to have convenient and continuous access to essential information.

Information presentation-Present information in a clear and unambiguous manner, using standardized symbols for controls and displays.

Status indication-Indicate the operational status of automated functions and integrated components and systems.

Decision making-Allow for expeditious, continuous and effective information processing and decision-making by the bridge team and the pilot.

Distractions-Prevent or minimize excessive or unnecessary work and any conditions or distractions on the bridge which may cause fatigue or interfere with the vigilance of the bridge team and the pilot.

Human error-Minimize the risk of human error and detecting such error, if it occurs, through monitoring and alarm systems, in time for the bridge team and the pilot to take appropriate action.
