Originally posted by ancientmariner View PostIrrespective of who pays for what we need to ensure that the ship is cleared, at design stage, to be fit for all the purposes intended. Some naval vessels are designated for Military Operations Only Not War. Some are more hardened such as Holland Class and can take a more vigorous defensive action. Looking at a recent head on shot of a p60 vessel I noted all the bridge windows are obscured by equipment consoles which means that from aft of the consoles there is no near water view for the bridge watchkeepers. It must make close quarters maneuvering a bit fraught and detract from situational awareness. Visual aspects of navigation must always remain paramount as all ship surface movements are to the choice of those in control and can lead to collision through been unaware of closer targets, especially at night.

View of Bridge wing from above.
The Gentleman is standing at the centre bridge window. You'll note there is a gap behind him where there are no consoles. Should the OC chose to remain in his seat, he has an unobscured view forward at all times.
The Location of the OCs seat, showing the overlooking view it offers.
I can only recommend you take the time to visit one of the vessels for yourself someday. Don't be afraid to tell them your background and the crew will be more than happy to show you around. Some exers even partake in an annual "trip on a ship" though I appreciate this is not to everyones taste. The situational awareness the combination of consoles and visibility provides is excellent. Granted P31 had a better view aft from the bridge, but she was a notable exception in service.
It is still light years ahead of operating with radar at night in the 70s and 80s, with your ARPA either behind a curtain or under a cone.For now, everything hangs on implementation of the CoDF report.

Well he is never going to be alone on the bridge in any situation. Would be different in a merchant vessel of course. The vessel can be conned from either bridge wing or the normal position.
The layout in my opinion is a vast improvement on days of old. Helm and engine control are out of the line of sight of the OOW or the OC. Meantime within his peripheral are MFDs showing anything from engine management to radar, ECDIS, AIS and if necessary EOD. The area in front of these consoles allows him the advantage of no light pollution from consoles should he need to focus on distant lights etc. Last skipper I had used to throw a teatowel over the Radar screen at night to save his night vision.
Many of the displays are also available to the skipper in his stateroom, via his PC.
You should really try and get a jolly on her.For now, everything hangs on implementation of the CoDF report.

What about external cameras aft facing and forward facing starboard and port? would they not be a useful secondary input for narrow nav?"He is an enemy officer taken in battle and entitled to fair treatment."
"No, sir. He's a sergeant, and they don't deserve no respect at all, sir. I should know. They're cunning and artful, if they're any good. I wouldn't mind if he was an officer, sir. But sergeants are clever."

Yes, CCTV covers both RIB launch areas as well as aft, and the EOD provides 360 day and night optics if required. (except for a slight blind spot directly behind, obscured by the ships mast and funnel of all things. Often wonder why this piece of kit is not mounted at or near the masts highest point?)
Didn't Eithne have FCS on both bridge wings?For now, everything hangs on implementation of the CoDF report.

IMO it's a fairly hefty blind spot:
I know the NS aren't fools - there's an ideal spot for another EO turret beside the satellite domes to cover that area - I'd love any vessel doing anything beyond a fishery patrol in Irish waters to have the second system, but €€€€ etc...
I imagine we'll see the Rheinmetalls replaced with RWS and their own EO system in the next 10-15 years and that will cover all angles.Last edited by pym; 23 August 2017, 22:19.
