Newport News Shipbuilding (NNS) in the US has been preparing for a re-entry into the commercial shipbuilding market for several years. Those preparations resulted in the signing of a contract in October 1994 for the construction of two 46 500 dwt products carriers. This is the first contract for a US shipyard to build commercial ships for a foreign owner in 37 years. In developing the hull form for the standard product carriers DOUBLE EAGLE, NNS performed studies to determine the economic and hydrodynamic effects of alternative bow configurations on a representative modern, high-block tanker. The objectives of the study were to update NNS commercial ship speed-power database, investigate the application of state of the art computer software, and create a bow design which strikes a balance between hydrodynamic performance and producibility. To achieve these goals, NNS used computational fluid dynamics (CFD) software to mathematically analyze several candidate bows. These designs were then model tested in a model basin to validate the results of the CFD codes. Construction costs were then estimated for each design and finally, the bow forms were compared on an overall economic basis.
