The New Exploration Cruise Ships by Sunstone Ships Rely on ProfiSeal Technology

Safety is of the highest priority for Sunstone Ships Inc. from America. Their new cruise ships of the “Infinity Class” are fitted with the fireproof bulkhead seals made by ProfiSeal.

The ingenious construction of the bulkhead seals ensures that a fire in the engine-room cannot spread further throughout the ship. In case of a fire, carbon dioxide is released inside the actual fitting, suffocating the fire at this point and so protecting the actual seal rings.

The new ships, which are built in Jiangsu, China, are not only exemplary in fireproofing. Special engines and exhaust cleaning systems will minimise emissions. “We are proud to be part of such an forward-thinking, progressive project with our product”, said Dr. Tobias Müller, Managing Director of the ProfiSeal GmbH, adding:  “as a specialist for the development and production of reliable and long-living seals for shafts and bulkheads.”

The fireproof bulkhead-seal by ProfiSeal is the world’s only fireproof bulkhead-seal to Class A-60. The classification is internationally recognised. The DNV GL have certified the fireproof bulkhead-seal, as have BV (Bureau Veritas) and KR (Korean Register).

The seal is available for shaft diameters of 50 to 500 mm.

It is made for temperatures from -5° to +950° Celsius.
