Vessel seakeeping

Vessel seakeeping — motions, natural periods, comfort

Ask Deckhand to estimate a vessel's motions, natural periods and motion comfort in a given sea state.

Run it on Open Deck

What you can ask it to do

  • Estimate vessel motions and accelerations from its RAOs and a sea state.
  • Report roll, pitch and heave natural periods.
  • Screen motion comfort and operability for the operation.

Questions

What does a seakeeping screen tell me?

How a vessel moves in a sea state — motions, accelerations and natural periods — and whether motion comfort and operability limits are met for the operation.

What inputs are needed?

The vessel's response amplitude operators (RAOs) and the sea state (wave height, period, spectrum). Deckhand can also prepare the hydrodynamic model that produces the RAOs.
