NSRP_LOGO.jpg

$17.1 Million in New Cost-Reducing Shipbuilding R&D Projects The Executive Control Board of the National Shipbuilding Research Program (NSRP) has awarded funding for five new research and development projects to continue the program’s mission to reduce the costs associated with U.S. shipbuilding and ship repair. These new projects, valued at approximately $17.1 million in both Navy funding and industry cost share, were among those proposed in response to a May 2011 Research Announcement. The NSRP collaboration periodically funds R&D projects to advance technologies and improve processes to reduce shipbuilding and repair costs for the Navy and the shipbuilding industry. The current project portfolio reflects the program’s strategic focus on:   • Reduction in Total Ownership Cost of ships. • Improved quality in ship construction and/or repair. • Improved energy efficiency and environmental impact in shipyards and ships. A brief description of each of the new projects, with a list of participants and funding information, follows:   SHIP CABLE MANAGEMENT Project Lead: Newport News Shipbuilding Team Members: TechnoSoft Inc.   Objective: To adapt, enhance and customize wiring application software applicable to all ship programs in order to reduce cost and time for validation of cable layout design, creation of wiring and signal schematics, generation of production work

AWS Revises Specification for Underwater Welding Code

A revised edition of the American Welding Society’s AWS D3.6M Underwater Welding Code, has been published.  The standard known as D3.6M:2010 supersedes the 1999 edition. The 142-page book covers underwater welding in both dry and wet environments. All provisions of the document apply equally to new construction and to modification and repair of existing structures underwater.  Initially applied as a means of temporary repair for damaged steel-hulled vessels


New Hobart Flux-Cored Wires

FabCO 70XHP

The newest addition to the Hobart family of AWS E70T-1 welding wires— the Hobart FabCO 70XHP gas-shielded flux-cored wire — offers low fume generation rates to help improve operator comfort and high deposition rates that help increase productivity, the manufacturer said. The new wire complements the FabCO TR-70 and FabCO RXR wires currently offered under the Hobart brand. Together, the three wires provide a continuum of benefits


Future Naval Force May Use the Strength of Titanium

ARLINGTON, Va. - Steel may have met its match: An Office of Naval Research (ONR)-funded project will produce a full-size ship hull section made entirely with marine-grade titanium, using a welding innovation which could help bring titanium into future Navy ship construction, officials announced. The contractor team building this section recently completed the industry's longest friction-stir titanium alloy welds and aims to complete the ship hull section this summer


STATS Group Completes Hydrostatic Testing

In-Line Weld test tools provide hot-work barriers and localised hydrostatic testing

Let the Buyer Beware

A touted new procedure for welding cost Brad Phillips his new vessel, when the process proved faulty and incomplete. Boat buyers in the current depressed market need to be aware of shady operators that might not be able to deliver all they claim. One recent victim of this situation was well-known Alaska excursion vessel operator Brad Phillips. At the start of 1997, Phillips contracted for a new $4.2 million all-aluminum catamaran, hoping to have the boat ready by the Alaska summer season


Miller's XMT 450 MPa Simplies User Interface
