PT Nautilus

Introducing the PT Nautilus,
This is a fully recreated version of the real tug boat of the same name.
She was the first tug boat that I engineered on and as such got to know her quite well.
This is an advanced build with most systems realistically recreated.

The Basics:
PT Nautilus was built in 1971 and is still turning a profit in the Brisbane river, Australia.
Fully recreated exterior and interior including a highly detailed engine room which, for the most part, is accurate to the real life counter part.
She has two main engines and one auxillary engine.
Top speed of 14 Knots .
Is suitable for standard towing , pusher config and towing alongside.
Can be controlled via the wheelhouse or flybridge, with use of station selection.
Has fire fighting capabilities.
Independant throttle and nozzle control as well as dual control system. This allows high maneuverability, the vessel can even be "Crabbed" sideways and perform small or large radius turns in any direction.
The real Nautilus is steered via rotatable nozzles around fixed propellers, however due to game game limitations I was unable to simulate thrust vectoring properly with this setup so I changed them to allow the propellers to rotate with the nozzels. This is why you will see prop shafts in the engine room ( rotating inline with engine RPM) but none outside the hull.
Fresh/ Potable water system which supplies galley, toilet and shower.
Sullage system which collects waste from galley, toilet and shower and stores it in a holding tank where you can pump it overboard.
Tiller room with tiller arms that turn with nozzles' rotation.
Fully detailed galley, mess and bunk room.
Realistic bilge pumping system with manifold and high level alarms.
Engine room fire suppression system with emergency fuel and fan shut offs.
Fuel oil tank high level alarms.
Engine and battery management alarms.
For the most part this recreation looks and feels like the real life counterpart, with every button and system in the correct place. Walking around the deck and inside the compartments, all the proportion feel very similar. Some changes were made to accomidate the 0.25m block thickness and button sizes ( Wheelhouse extened slighly to allow for dash buttons.).
Please note that exiting void spaces requires jumping from the top of the ladders. This is especially true for the main engine room exit. You will need to continue pressing the climb ladder key (W) and then simultaneously press the exit ladder key (F) and crouch (Ctrl) when the top of the door frame is at eye level.

Start Up Proceedure:
*Enter the engine room
*Open either Port or Starboard sea water intake.
*Close AUX ISO (auxiliary engine and generator isolation) breaker.
*Aux glow plugs.
*Start Aux
*Head over to main switchboard
*Flick main breaker
*Close all breakers (fuel transfer pump is only needed on if transfering fuel between tanks)
*Next to the main engine control board, close both Port and Starboard main engine battery isolators
*On the control board, activate pre lube then push the starter
*Head up to the wheelhouse
*Close wheelhouse battery isolator (Located at the base of the bench seat)

*When using the thottle to switch between ahead or astern gear, let her sit in idle for a moment (You will hear the engine revs increase and see the indicator lights) before applying a small amount of the opposing gear / throttle. This allows the engine to wash off some prop speed. Crashing through the gears will stall the engine. This is recommended for both Independant and dual throttle control modes.
*Steering only requires small inputs ( under +/- .06 ) when steaming, higher inputs are used during maneuvres at low speed.
*The anchor and tow winch hydraulics are operated by the Starboard Main Engine so this must be running for them to haul in.
*The Port and Starboard steering hydraulics systems are operated by their respective engines, they must be running to operate the nozzles. Eg. If Starboard engine cuts out you will loose the ability to steer the Starboard nozzle.
*All buttons are labeled so if you're unsure of something it can pay to just walk around and read some of the controls and indicator descriptions.
*This is an ongoing work in progress so there still maybe a few quirks here and there. Feel free to let me know if you spot something odd.

A very special thanks goes to both Chris Olsen and Tajin
Chris Olsen's Medium Duty Tug hull was used as a starting point and scaling tool.
Tajin's Heading Hold logic and wind speed calculation (PenguinRO5's conversion to microprocessor) was used in the auto pilot.

Yes that it is bilge/fire manifold. It uses the hydrant as the overboard discharge as well.
I feel like it is a little slow at pumping the bilges, that is one of the tweaks I would like to make along with the new dash components.

is the only way to empty the bilge using the fire system?

Hey Bluesky, when in the editor click on the select tool. It looks like a arrow pointer thing at the top of the screen. Then just click on the button and you will see a little box on the left of your screen you can type in.

@El Farto how did you give name to buttons?

Hope people are still enjoying this little tug boat. I adjusted the engine temp readouts to stop premature alarming, made the engines more responsive to shut down and added a heater to the accommodation area.
