DNV GL Updates Shaft Alignment Design Rules
Classification society DNV GL DNV GL informed that it will update its shaft alignment design rules to differentiate between Environmentally Acceptable Lubricants (EALs) and mineral oils in stern tubes.The update, will apply from 1 July 2019, and is based on the phase 1 findings from the joint development project (JDP) DNV GL has been operating along with the Swedish Club, Norwegian Hull Club, Gard and Skuld.The JDP was prompted by an upsurge in stern tube bearing failures that coincided with the increased uptake of EALs after the introduction of regulations requiring their use in commercial vessels trading in U.S. waters in late 2013.In phase 1 the JDP has focused on mapping out differences in the load carrying capacity between EALs and mineral oils.
BAE Systems, Flinders University to Train Shipbuilding Workforce
A new agreement between BAE Systems Australia and Flinders University will see students and industry working together to develop new ways to provide Australia’s defence force with the evolving capability it needs and train the shipbuilding workforce of the future. BAE Systems is one of three companies bidding to build nine Anti-Submarine Warships for the Royal Australian Navy. The company is proposing an Australian variant of the Global Combat Ship currently being manufactured in the UK for the Royal Navy. Flinders University will receive access to BAE Systems’ digital shipbuilding tools, processes and methodologies and turn these into development programs to train the people who will build the Future Frigates and integrate the ships’ complex operating systems…
DNV GL Launches Project to Test Biodegradable Lubricants
Classification society DNV GL has launched a new joint development project (JDP) in cooperation with marine insurers The Swedish Club, Norwegian Hull Club, Gard and Skuld to test the potential influence of Environmentally Acceptable Lubricants (EALs) on failures in stern tube bearings. DNV GL will oversee detailed laboratory testing of EALs by Leonardo Testing Services Ltd. at the University of Sheffield (UoS), UK. The JDP has been prompted by an increase in stern tube bearing failures over the last few years.
Icebergs Turn Oceans Greener
Icebergs the size of Singapore could be playing a bigger role in how much carbon the Southern Ocean absorbs than previously thought, a new study says. Icebergs that break off Antarctica could account for twice as much carbon dioxide stored in the Southern Ocean than previously believed, the study suggested. The findings were published this week in Nature Geoscience. Pioneering research from the University of Sheffield’s Department of Geography discovered melting water from giant icebergs, which contains iron and other nutrients, supports hitherto unexpectedly high levels of phytoplankton growth. These plankton blooms - which can stretch for hundreds of miles - then absorb a substantial amount of carbon dioxide from the atmosphere and lock it into the ocean depths.
Huge Iceberg Broken off Antarctica Heads for Open Ocean
Scientists are monitoring an iceberg roughly six times the size of Manhattan - one of the largest now in existence - that broke off from an Antarctic glacier and is heading into the open ocean. NASA glaciologist Kelly Brunt said on Wednesday the iceberg covers about 255 square miles (660 square km) and is up to a third of a mile (500 meters) thick. Known as B31, the iceberg separated from Antarctica's Pine Island Glacier last November, Brunt added. "It's one that's large enough that it warrants monitoring," Brunt said in a telephone interview, noting that U.S.
Enormous Antarctic Iceberg a Possible Threat to Shipping
An Iceberg, the size of Manhattan in area, was derived from the Pine Island Glacier, and is currently moving through the Southern Ocean. To keep track of its movements and melting Professor Grant Bigg of UK's University of Sheffield has been awarded a £50,000 grant from the Natural Environment Research Council (NERC) for the 6 month project. The research collected by tracking its movement, and modelling its trajectory and melting, through the ocean will be used by the shipping industry and associated agencies currently using the Southern Ocean in providing more accurate ice warnings.
DNV Anchors Graduate Commitment with Launch of UK Scheme
DNV, the multinational provider of risk management and sustainability services, has established a UK graduate program to develop new talent in the energy and maritime industries. DNV has welcomed 14 graduates on the scheme this year with plans already in place for a similar intake again in 2013. The two year program gives graduates an insight to the many areas in which DNV operates and the diversity of services provided by the independent organization. The scheme offers flexibility for graduates to experience different industries and tailor their own career path. Graduates spend four six month blocks in different teams within DNV to gain broad experience of the company and the disciplines they want to gain expertise in.
