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.
What are the principles of Navigational Bridge Design?
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.
Rule 5 of the Collision Regulations
These design principles support the most important rule in the COLREGS, Rule 5
“Every vessel shall at all times maintain a proper look-out by sight an
d hearing as well as by all available means appropriate in the prevailing circumstances and conditions so as to make a full appraisal of the situation and or the risk of collision.”
Where to look for more detailed information
- MSC/Circ.982-Guidelines on ergonomic criteria for bridge equipment and layout
- SN.1/Circ.288 –Guidelines for bridge equipment and systems, their arrangement and integration
- MSC.86(70), Annex 3-Recommendations on Performance standards for an integrated navigational system
- IACS requirements concerning navigation
The broad principles of Regulation 15 will be expanded with some practical detail in tne next post when I dig into Circular 982.
