Ancillary equipment PureBallast first on
tankers Alfa Laval has received an order for its PureBallast system to be installed onboard two newbuild bitumen tankers to be built at China’s Wuhan Nanhua Huanggang Jiangbei Shipyard, for owner Nynas. Tis is reckoned to be the first ballast water treatment installation to be adapted for a hazardous tanker environment. Scheduled for delivery in 2010, the Nynas vessels will each have a ballast tank capacity of 2150m3 treatment system flow of 500m3
and a /h. Due to the cargo
and the resulting gas risks onboard, the vessels will have their PureBallast systems above deck rather than below. Te ballast water treatment solution, which involves a specially designed enclosure, is also said to be the first to be certified for use onboard petroleum tankers. Te finished design for the Nynas tankers places
PureBallast in a pressurised structure on deck, rather than in the engine room. With a double- door construction that will act as an airlock and an over-pressurised ventilation system, the housing eliminates the need for an explosion-proof treatment system, allowing PureBallast to be certified by Bureau Veritas for use in this environment.
PureBallast breaks in to gas market.

Lifesaving equipment Viking floats with
Donut Viking Life-Saving Equipment has signed an agreement with UK-based Donut Safety Systems Ltd to distribute the ‘last man overboard’ Donut safety device. Originally designed for high-rise buildings, the
Donut has subsequently been applied as a tertiary means of escape from offshore platforms. Now, its potential is being tapped for commercial ships. Te Donut enables personnel to escape by means
of individually controlled descent, once it has been attached to a handrail or other load bearing structure. It is said to require little physical effort to use. Viking global sales manager, Jorgen Holm, said:
“The Donut is a safety measure for unforeseen circumstances that suits our current range of high quality lifesaving appliances well. It’s already popular in the offshore market, but the advantages for commercial shipping are clear as it enables the last person onboard to evacuate directly from the ship into a throw-overboard liferaſt in a quick and safe manner. It is also a very good alternative to evacuation ladders and knotted ropes, because it is compact and has a lower risk of tearing immersion suits during descent.”
