Stern Tube Lubrication System Marine Engineers Knowledge The technologies behind all wärtsilä oil lubricated sealing products are a result of many years of experience and development. maximising longevity while facilitating servicing and maintaining exemplary sealing performance. our fundamental philosophy has always revolved around providing environmentally compliant solutions which meet world. The lubricant spillage in real ships is estimated to be a hundred times larger and in the opposite direction. 44 although seals operating with a water oil interface were not tested, the latter suggests that there is an additional oil spillage mechanism in ships which was not captured by the stern tube test setup developed. the transient.
Usual Disposition Of The Stern Tube Seals And The Oil Tanks In A Ship Downlo 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. 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. Disposition of the stern tube oil tanks in a ship. 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. Material is collected in the oil filter of stern tube oil lubricated systems. depending on the vessel type, lubrication for the stern tube seals, stern tube, and strut bearings is accomplished by seawater, freshwater, or oil. 1 some small boats and crafts use surrounding seawater for cooling and a greased bearing for lubrication.

The stern tube is a hollow tube that holds the shaft that connects the engine to the propeller. this shaft is known as the tail shaft or the propeller shaft. the tube is made from either cast iron or mild steel. as the propeller is submerged at all times, the stern tube connects the inside of the ship (engine room) directly to the seawater. Check for oil leakage from seal 5 in the forward area. following method can be used to inspect the integrity of the 4 seals stern tube in dry dock: feed oil from the stern tube tank keeping the oiling line valve closed for 3 and 3s seals. open the drain plugs of chambers 3 – 3s of aft sealing and 4 – 5 of forward sealing to check oil leakages.
