Route planning based on ship roll in numerically modelled heavy seas

Challenges in navigation route planning for seafarers are ship safety, travelling comfort and reasonable voyage duration time. Various routing models available to shipping companies aim to partially or fully avoid bad weather and heavy seas. The presented study analyses the situation when heavy weather cannot be avoided and the ship passes through a storm having the seafarers making immediate decisions about course and advance speed. Possible routes were evaluated for an existing shipping line across the Adriatic Sea during strong south-east wind that occurs several times per year. Heavy sea, resulting from strong winds, was calculated by a spectral wind- wave model SWAN. Ship response was computed by a combination of analytical expressions and spectral analysis. Ship roll was chosen as the seakeeping criteria for route planning.
