Aveva: New Paper on Integrated Steelwork and 3D Plant Design

Paper highlights how integrating structural steelwork and plant layout design can reduce project cost, risk and delivery time Aveva released ‘Bolting it all together,’ the latest in its series of business papers, which discusses how integrating structural steelwork and plant layout design can reduce project cost, risk and delivery time. The paper explores the considerable business advantage that EPCs and Shipbuilders, working on plant/offshore projects, can gain by using a specialized steelwork application that can be used efficiently within a plant design solution to support close, collaborative working through an entire design and construction project. “Steelwork often accounts for a disproportionate level of project risk, rework, and overruns in cost and delivery,” said Bruce Douglas, Senior Vice-President, EDS Strategy and Marketing, Aveva.  “It is common industry practice to subcontract steel detailing and fabrication to specialized companies, with most plant design solutions not extending to the steelwork design/fabricate/construct workflow. Communication links are therefore stretched in a process that demands close collaboration, resulting in general project inefficiency that can lead to costly rework and program overruns.” The business paper demonstrates the need for EPCs and Shipbuilders to consider solutions that enable the development of steelwork design concurrently with the rest of the layout

The Ice Strengthened, Twin Hulled Susitna

The M/V Susitna is an Office of Naval Research (ONR) platform demonstrating variable geometry/variable draft capability in a twin hull marine vessel.  Tests and trials of this first of class vessel will demonstrate its ability to operate as a deep draft, high speed vessel capable of carrying large payloads in high sea states with a stable ride, then transition to a shallow draft, beachable, landing craft mode capable of delivering Expeditionary Forces to the beach.

Great Ships of 2001 -- Polar Endeavour

Representing an important milestone for U.S. commercial shipbuilding, the delivery of the 141,740-dwt Polar Endeavour signaled the unfolding of a major new chapter of investment in the fleet dedicated to coastwise transportation of Alaskan crude oil. Giving first form to the Millennium concept, the tanker has been purpose-designed for trade in the world's most environmentally-sensitive waters. While Polar Tankers' main requirement of the Millennium-class is to ship crude to Puget Sound from

ABS: Technical Guidance For Ice Class Tankers

ABS offers comparative structural arrangement studies for the design of each tanker ice class designation using procedures outlined in a just released “Guide for Non-Linear Finite Element Analysis (FEA) for Side Structures Subject to Ice Loads.” The guide is an outgrowth from ABS’ work with the principal Asian shipyards developing new aframax ice class tanker designs in response to the increased traffic in the Baltic
