Stern Tube Lubrication System Youtube The stern tube is a hollow tube passing at the lower stern part of the ship carrying tail shaft and connecting it to the propeller out at sea, bearing for the tail shaft, lubrication arrangement and most importantly the sealing arrangements. the stern tube bearing arrangement and sealing plays a vital part in ship’s operation and pollution. Stern tube lubrication system consist of a drain tank which acts as a reservoir for the storage of oil. drain tank is a double bottom tank located in the aft of the engine room. the system consists of two sets of oil pumps. the purpose of having two pumps is that if one pump fails the other pump can take over and continue the operation.
What Is Stern Tube Its Working And Function Marine Infosite As the name suggests, the oil lubricated stern tube uses oil based lubricants for stern tube lubrication. credits: borras, xavier & nieuwendijk, roy & ramesh, vikram & rooij, matthijn & schipper, dirk jan.

Figure 8.15 oil lubricated stern tube (simplex type) the static lubrication system for vessels with moderate changes in draught, have header tanks placed 2—3 m above the maximum load waterline. the small differential pressure ensures that water is excluded. the cooling of simple stern tubes, necessitates keeping the aft peak water level at.

The function of the stern tube seals is to prevent water entering the stern tube as well as to minimize the lubricant spillage to the marine environment and engine chamber. to increase the reliability of the system, a few sealing rings are mounted in line at both ends of the stern tube conforming the aft and forward stern tube seals packages.
