Stern Tube Bearing · Shaft Line Equipment
Crews and engineers on board vessels rely heavily on robust and reliable bulkhead seals to ensure the integrity of propulsion shaft lines. These critical components, manufactured by SKF Marine GmbH under the designation Bulkhead seals, split and not split version and its design, are essential for maintaining the efficiency and safety of marine operations. Common failures such as wear in bearings during coastal or shallow water operation due to sand and silt, leaks from shaft seals causing oil loss into the sea, cavitation erosion on propeller blades, and misalignment leading to uneven bearing wear can significantly impact performance. To mitigate these issues, SKF Marine GmbH recommends keeping sealing elements and wear measurement tools on board, with a lead time of 4-8 weeks for spare parts. Regular maintenance is crucial; bearing play should be measured during docking, shaft seals inspected daily for drainage, oil analysis conducted quarterly, and propeller inspections performed during docking to ensure optimal operation. The Bulkhead seals, split and not split version and its design, are DNV approved, ensuring compliance with stringent maritime standards.
