Implementing Neat Construction in a Mid-Tier Shipyard: The Story of How Bollinger and Vigor Shipyards are Moving Toward Zero Stock Construction

摘要

In June 2010, NSRP awarded the project entitled “Weld Shrinkage and Distortion Allowance Data Model for Neat Construction Ship Design Engineering,” a collaborative research project which included four shipyard team members; Bollinger Shipyards, HHI- Ingalls Shipyard, Vigor Shipyard (Seattle), and Marinette Marine Corporation. The purpose of the project was to provide comprehensive weld shrinkage and distortion solutions intended to enable neat construction capability across the U.S. shipbuilding industry. This paper will provide highlights of the NSRP project and describe how two of the participating shipyards, Bollinger Shipyards and Vigor Shipyard, have taken significant steps towards improving their distortion control, improving their accuracy control and incorporating weld shrinkage factors into their designs as steps towards achieving neat construction.
