OCTOPUS Office 6 Voyage Simulation

OCTOPUS Office 6 Voyage Simulation is an addition to OCTOPUS Office 6 Basic
and contains the following features:
  • Creation of voyages
  • Calculation of spectral moments based on the Argoss Wave Database
  • Viewing sea conditions along the voyage
  • Viewing short term statistics along the voyage
  • Viewing long term statistics

Analysis sequence to calculate statistics and probabilistics.

Voyage simulation

In Octopus Office, voyage simulations can be carried out by using the Argoss Wave Database. This historical world-wide wave database is the product of satellite observations and a 3rd generation wave model. It covers a period of 15 years with a time resolution of 3 hours. The wave condition at a particular date, time and location is described by a distribution of the energy, the direction and the directionality, as a function of the frequency. The position list of the voyage is used as input for voyage simulations. These simulations are carried out for different dates and time of departure, and repeated until convergence is obtained after 'N' simulations. The design values can be derived by defining a required success rate after simulating N voyages.

Once the responses are calculated the sea conditions, short term statistics and long term statistics are calculated. By default the value for long term statistics are calculated for 1, 2, 5, 10, 20, 50, 10 and 1000 years.

Responses can be calculated for:
  • the six degrees of freedom
  • vertical relative motions
  • sectional loads in longitudinal, transverse and vertical directions
  • motions, velocities, accelerations (with and without gravity), angular velocities and angular accelerations anywhere on the ship
  • any combinations of the above mentioned responses

Note: The Argoss Wave Database is not part of Octopus Office 6, but is sold separately.
