Process description
Ships with drive shafts that run through one or more bulkheads require bulkhead seals to prevent any possibility of water from rushing into adjacent sections of the ship – and therefore provide a high level of protection against flushing. The work and observance vessel Weserplate with a length of 27.1 m (1,066.93”), a width of 6.7 m (263.78”) and 1.19 m (46.85”) depth of flotation requires a bulkhead seal to protect the engine room against flushing.
Problem and challenge
The shaft feed through in the bulkhead of work and observance vessel Weserplate requires a bulkhead seal. The entire drive system needs to be highly reliable in order to ensure that the ship offers year round service without ever being laid up for repairs – and call for a minimum of maintenance at the same time. The shaft runs with 1,800 min-1 revolutions. The diameter in the sealing area is 98 mm (3.86"). The seal operating temperature in the engine room is maximum 45 °C (113 °F) according to the specifications of German Lloyd. The operating pressure in case of damage will not exceed 1.5 bar (21.76 PSI). The installation length should be as short as possible. The seal should guarantee an easy assembly.
EagleBurgmann Espey solution
To fulfill the application requirements Espey designed the bulkhead seal Espey WDK-BHS with 2 segmented seal rings made of a PTFE-carbon compound and split housing for easy assembly. A barrier gas port is not needed. The seal width’ of only 30 mm (1.18") meets the customers’ requirements. The seal guarantees a long-term operation time without any maintenance.
