Bunkering Vessels
« on: March 29, 2010, 09:17:50 pm »

Greetings.
I am doing my version of the Deans Marine RIX HARRIER bunkering vessel.
My question is: would such a vessel engaged in pumping activities display any special signals either shapes by day or lights by nighrt.
I can understand that it would display R.A.M signals but are ther any special ones.
Many thanks

 Peter, I have attached a photo that I took at Southampton of the QE2 being bunkered. Not enough breeze to show the flags clearly but I hope it gives you some idea.

Peter, I have found another photo of a bunkering tanker that I took at Portsmouth on which you can see the red flag flying from the port side yard of the foremast, as described by tassie48.

Thank you for your reply, I presume that the red flag would be replaced with a red light showing all round at night?

Thank you for your reply. I wonder if I can ask for a clarification regarding the position of the flag and the light. Do I understand correctly that the signal is displayed on the side of the mast that the discharge is taking place.?
Many thanks for you kind assistance.
regards.

PD if you are lashed up i.e. tied up along side just say on the port side to the ship the B flag is on the Stb side of the mast same with night light this gives better viewing from other ships to be seen from a distance that is what we use to do as per the book Captain Tich was our master and a by the book buoy even down to the spring lines and the aft deck fire tug  tow line made fast in case we had to be taken in tow by a tug tassie48.

Some more questions if I may.
Which vessel carries the flexible hose that connects the two vessels together?
How many discharge points are ther on each side of the barge?
Where is the pumping controlled from?

From the attached photo you'll see that the bunkering tanker is carrying the connecting hoses. The number of discharge points would depend on whether the vessel is designed to carry various grade of oil and the port and starboard sides are usually identical. The pumps and valves on modern vessels are usually operated from a control-room, generally overlooking the main deck.
In my days at sea the valves were operated manually from the deck and pumproom by the deck officer of the watch and the pumpman. The pumps were started from the engineroom by the engineer on watch and stopped from a trip mechanism at the top of the pumproom.

We use to carry our own flex hose which our engineer use to look after his baby the hoses were kept on the crane all the time and coupled to the manifold same as Tankerman states we use to get overtime when on filling watch and lots of goddies from the ships crew tassie48

Greetings Tankerman.
Sorry to bother you again, can you estimate how long the jib of that crane is on the picture you posted, and is it telescopic or a fixed length boom.
Regards.

Chris' picture reminded me of some I took at Portsmouth.

Peter asks.... "can you estimate how long the jib of that crane is on the picture you posted, and is it telescopic or a fixed"

From .jpg 072 Peter.....the boom appears to be of 3 stage hydraulic telescopic design....you can get a good handle on the height of the crew on deck to estimate the boom, or even just the lowest section then x by 3 ..... %% ....Derek

Thanks everybody. Nice pictures Martin.
I estimate that the 3 stage jib will be about 9 metres fully extended about 30 feet in real money.
That seems like a sensible number.
Nice work chaps.
