SAGE UNDERKEEL ALLOWANCES FOR VESSELS IN NAVIGATION CHANNEL

J.M.A. Spencer, E.C. Bowers, G.H. Lean

Abstract


This paper describes methods used at Hydraulics Research to evaluate risks of ships grounding in navigation channels due to wave induced vertical motion. Risk assessments are then used as an aid to optimising channel depths with a view to minimising dredging, A mathematical model of ship response in waves in shallow water is presented and two case studies are considered to, show how methods may be applied.

Keywords
