BACKGROUND:
The computational prediction of ship performance holds the promise of expanding aspects of design analysis to include, for instance, maneuvering in waves and in shallow water. Additionally by providing more details of the flow physics, such as vortex and turbulent structures and their effects on forces and moments, improved design capabilities will be developed. AVT-161 expanded on the Simulation of Maneuvering (SIMMAN) workshop with more complex maneuvers such as course keeping in waves (free-running model) and in shallow-water (bare hull, captive model). While SIMMAN and AVT-161 were major steps forward in benchmarking computational prediction methods, more realistic conditions are required to assess and further develop computational tools for design analysis. In particular, course-keeping in irregular waves, shallow-water operation with propulsion systems and appendages, and ship-ship interaction need to be addressed. These are proposed as a follow-on activity. Relevance to NATO is based on the need for design capabilities for safe operation of ships in real sea conditions including maneuvering in waves, shallow-water, at-sea replenishment, ship-ship interaction, and tools which can be used to verify compliance with the criteria in the STANAG that is being developed by the Seaway Mobility Group.
OBJECTIVES:
The Task Group will identify appropriate test cases, applicable computational approaches, and available and required experimental data to provide recommendations for a technical team to achieve the expansion and benchmarking of prediction of ship performance in realistic operational conditions at sea and provide guidance for design analysis, including maneuvering in waves, shallow-water operations, and ship-ship interaction.
TOPICS:
(1) Identification and evaluation of appropriate codes and comparison methods; (2) Identification and evaluation of appropriate experimental data and test conditions; (3) Formulation of recommendations for the technical team.
