Roxtec delivers cable sealing solutions to firms operating right across the maritime sphere from commercial shipping and offshore to military, cruise and leisure. Two recent projects within the cruise and ferry market demonstrate the importance of safely sealing cables and pipes to protect against the multiple hazards experienced at sea.
Roxtec was recently approached by Royal Caribbean and shipyard Meyer Turku to deliver an all-inclusive sealing solution for TUI Cruises’ vessel Mein Schiff 6. The co-owners of the cruise liner were looking to source a cost-efficient, light-weight and long-lasting solution for sealing thousands of pipes and cables. Most importantly, they were also looking for certified protection against fire, gas, water and electromagnetic disturbance. Roxtec seals have since been used for penetrations in decks, bulkheads and cabinets in critical compartments such as the engine room, passenger and pool areas. In total, Roxtec worked on 6,065 sealed openings, including 3,781 openings for pipes and 2,284 for cables onboard the vessel which are sealed with Roxtec transits. Many of the transits include spare capacity for future needs.
Mika Tuokko, head of electrical outfitting at Meyer Turku, said: “Around one hundred installers have been working with Roxtec transits for cables on the cruise liner. The most important thing is to keep up the speed by handling fewer items. By using Roxtec instead of other systems we avoid 50 items in stock for each transit."
Certified peace of mind
Roxtec solutions are used to seal all types of penetrating cables, steel pipes and plastic pipes passing through decks and bulkheads, in and between different sections and constructions such as machine rooms, storage rooms, living compartments and the bridge. They can further be used in various types of control cabinets, electrical enclosures and junction boxes. Roxtec’s solutions undergo hundreds of registered tests and approvals and have received more than 250 certificates demonstrating performance and resistance to hazards. The products are fire tested and approved for use in A, B and H class rated sections according to IMO Res. A 754 (18)/ IMO FTP 2010 and SOLAS, and tightness tested according to DNV type approval program 8-471.19-1.
Roxtec seals ensure protection against fire, water, gas, salt, and dust. They can further protect against the risk of explosion, lightning strikes, and noise. They also offer solutions for bonding, grounding, and EMC. The system is well suited for sealing of hydraulic pipes, since the rubber absorbs vibrations.
Roxtec’s process for developing standard sealing products and creating customised solutions is supported by its procedures for testing. It benefits from a technical centre with an advanced ‘test laboratory’ in combination with a fire laboratory, used daily for R&D tests.
The firm’s sealing solutions are particularly attractive to the cruise line and ferry market because they provide flexibility. There is an ability to add cables, metal and plastic pipes whenever it is time for new installations. Upgrades can be performed while cruising – and without risking structure or passenger safety. Within the cabin Roxtec seals are light-weight, versatile and easy to install. They prevent fire, gas or water from entering the next compartment. The seals are also area efficient and require minimal welding and insulation.
Another recent project involved the replacement of pipe seals on the Danish ferry operator Scanlines M/F Berlin and M/F Copenhagen with Roxtec transits. Scandlines dual officer Joachim Lund said: “We selected Roxtec as the overall supplier of cable and pipe seals because of the volume of different pipe penetrations and retrofits to handle. The bulkheads must withstand 2.5 bar water pressure, and with Roxtec we covered all our needs for quality and flexibility.” Roxtec also provided full documentation on sealing and insulation requirements and supplied drawings including solutions with all necessary type approvals.
Scandlines further uses Roxtec seals instead of traditional cable glands in the cabinets within the engine room. The reason is that they want to increase quality in general – and specifically for the fire-fighting system. Fini A Hansen, coordinating superintendent at Scandlines, said: "Safety is extremely important for passenger lines. We invest to be sure that all cable and pipe transits are in order and that we meet all safety regulations. Roxtec know what to do, and our people who work with Roxtec transits are very positive about the product.”
