This page is the centre for material on bridge design.  It is expected to be an active area.
The topics covered are
   * Modern automated bridges [[#AutomatedBridges]]
   * Conventional or traditional bridge design [[#ConventionalBridges]]
   * Offshore bridge design [[#OffshoreBridges]]

#AutomatedBridges *Automated Bridges* 

Plenty to be said I hope.
Certainly plenty to be done.

The user community has proposed that the problems and incidents associated with INS and IBS bridges are collated for consideration in the development of new IMO Performance Standards.  A page with hopefully simpler data entry has been set up at INSandIBSProblems.  

#ConventionalBridges *Conventional Bridge Design* 

 There is considerable discussion of the risk of falling asleep with a seated watchkeeping position.  There is less discussion of the risk of varicosis from prolonged standing.  The reference below seems to indicate that this can be a real risk.

Is this a workable arrangement? If the aim is to have a radio to hand when looking out of the window, then it would be fine, but if you had to operate the controls often, at night, on lookout, then maybe less so.

Indicators mounted over the windows have many advantages for shared situation awareness and for ease of reading when moving around the bridge. Does the design and arrangement of such indicators need better standardisation?

#OffshoreBridges *Offshore ships* 

The issue was raised by Donald Anderson of consolidation of bridge design with control room design for offshore systems, especially for dynamic positioned vessals (drilling) and FPUs (production), etc, where some conflicts exist between the priorities of the Master (Ship operation) and Production (Process Control).
