Wartsila has received order for 10 fully integrated bridge systems for 5 icebreaking LNG Carriers to be built by Samsung:
That is right, two fully equipped bridges for each vessel. One facing forward for normal operation and one facing aft for when the ship is going astern to break ice.
Not that unusual on Offshore vessels, Ferries etc. but not that common on large LNG Carriers.
The harbour ferries here have Nav lights at each end. In the wheelhouse being used they had a bright lightbulb over the wheel which was only extinguished when the lights were correctly changed over.
Double ended ferries have two sets of navigation lights.
Modern once have one wheelhouse. Only the Captainās chair has to swivel when they change direction.(Nav.lights switch automatically)
More pertinent question is for harbour tugs that frequently move backwards between jobs. (??)
Of course, what they could have done was have two full sets of crews; one for going forwards and one for going forwards in the other direction.
Probably too simple to figure that one out.
Sounds like a joke. My icebreaking days were one way, with a shitty tug that I had to back up at times to ram it again. Shipyard loved us, but we delivered heating oil to the customers that needed it. Nothing like what these vessels go through. But was no picnic and very little sleep for the crew below.
Some early double-acting ships were built with two sets of navigational lights (ahead/astern), but the more recent ones have just one set (ahead). When these ships are going backwards, everyone is either moving very slowly or just stuck.
We have only one of our original ferries left and a group of volunteers are slowly restoring it on the hard.
They had a triple expansion steam engine driving a propeller at each end of the vessel. A rudder was also fitted to each end, the rudder at the " bow" being locked amidships by a pin on deck. I think the capacity of the ferries was about 600 passengers.
The ferries have been replaced by catamarans but it will be a great day when they get the old girl back in the water.
Sydney, Australia has some large ferries with two bridges, but I havenāt ever travelled on them.
