Te Single Pipe Metal (SPM) product is designed to
seal any kind of metal pipe in steel decks or bulkheads with its highly elastic EPDM (ethylene propylene diene monomer) rubber, offering an alternative to welding. Roxtec UK’s managing director, Graham O’Hare
says: “A crucial point is that it provides an alternative to the costly and laborious welding process oſten used to seal metal pipes. Tis process requires a re-paint after weld. In addition, current practices involve pipes being hit with hammers which can lead to damage. Our seal is easy to open up and re-seal for maintenance.” O’Hare describes the product as “a lightweight,
single-sided solution which is quick and easy to install,” adding that “the seal is made out of durable and malleable rubber, while the fittings are made out of acid-proof stainless steel.” The seal comes with an A-60 fire rating, is
watertight to 1 bar, gas tight to 0.67 bar, and comes in a range of sizes for pipes of 12mm-222mm.

Seals & bearings Keeping it clean
Tordon Bearings’ Water Quality Package (WQP) has provided Atlantska Plovidba’s Revelin with a clean
16
Thordon’s Water Quality Package allows shaft bearings to be lubricated when the sea chest is drawing in filthy river water
and consistent supply of seawater to the bearings while operating in filthy river water. Scott Groves, business development manager,
Tordon Bearings, says the vessel needed to function during ocean-going operations and in river entrances where the seawater is highly abrasive, and so by constantly running Tordon’s WQP the propeller shaſt bearings were able to be lubricated while the sea chest was drawing in filthy river water. Atlantska Plovidba’s vice-president, ship
management, Marin Matana, explains: “Our vessels trade globally, including in the USA. With the Vessel General Permit (VGP) in effect, we felt that the seawater-lubricated system was the perfect solution. It meets the U.S. VGP requirements and is the right choice for the environment.” Revelin is the second in a series of two
environmentally sustainable handy-size bulk carriers delivered by Qingshan Shipyard, China. Both vessels of the series (Revelin and Dubrava) were built to the Green Dolphin 38 design unveiled by the Shanghai Merchant Ship Design & Research Institute (SDARI) in 2012 and feature Thordon Bearings’ seawater- lubricated COMPAC propeller shaſt bearing system.
