Marine Coatings: Polyflake Protects against Corrosion

Photo: Polyflake

Corrosion starts from the inside out. The alkali that neutralizes acid water - and the acid water produced in a gas scrubbing system - are corrosive. Containment surfaces resistant to both alkali, acid water and their combination provide a safer ship with less expensive maintenance. While selecting metal alloys as more resistant to either acid or to alkali, facing all conditions simultaneously is problematic, as temperature plays an important role in pitting corrosion.Ultimately…

ClassNK: Guidelines on Laser-Arc Hybrid Welding

Classification society ClassNK has released Guidelines on Laser-Arc Hybrid Welding (Ver. 3) aiming to support the widespread application of laser-arc hybrid welding in shipyards. Laser-arc hybrid welding is a high quality and highly-efficient welding process which combines both laser and arc welding methods, capable of achieving the same depth of penetration as the standard arc welding process whilst also inhibiting thermal deformation due to its low required heat input. This guideline (Ver.

Trafigura's Impala Terminals Scraps Chinese Joint Venture

Commodity trader Trafigura said its logistics and warehouse unit Impala Terminals has scrapped plans for a metals warehousing joint venture in China and will also exit its refined base metals business.

Ukraine Crisis Pushes up Gold, Oil, Grains

Gold, crude oil and grains surged on Monday while industrial metals slid as investors reacted to escalating tensions between Moscow and Kiev after the Russian military tightened its grip on Ukraine's Crimea region. Concern about supplies pushed up crude oil prices by more than $2 a barrel and wheat and corn by 4-6 percent. Safe-haven buying sent gold prices to four-month highs. Base metals such as copper fell along with shares as investors ditched higher-risk assets and due to worries that a conflict could damage global growth. "Trade sanctions and a general ratcheting up of global tensions could also endanger the fragile global economic recovery now under way, hurting commodity prices in the process," analyst Edward Meir at broker INTL FCStone said.

GE’s Power Conversion business has taken a step in testing a viable way of producing large amounts of electricity from renewable resources using superconductors running at relatively high temperatures. The company completed trials of Hydrogenie, a power generator incorporating technologies that enable highly efficient production of electricity in a small space. Hydrogenie makes use of superconductors instead of copper for the rotor windings on the motor, operating at 43 Kelvin or -230°C.

NSRP Approves 11 Ship Production Projects

The Executive Control Board of the National Shipbuilding Research Program (NSRP) has selected 11 new Ship Production Panel projects, totaling approximately $756,000, designed to reduce the costs of Navy shipbuilding and ship repair. These relatively short, low cost projects were selected to complement portfolios of larger R&D projects funded through NSRP in responding to industry-consensus priorities and the Navy customer’s research areas of greatest interest. (Business Process Technologies Panel): U.S. commercial shipbuilding is important to maintain and modernize the industrial base for both new construction and repair of military ships and craft. The United States builds less than one percent of ships worldwide.
