    Scope of Work

    In total there are eight options one can use to compute the location of the center of gravity when a compartment is not filled completely (slack). This is a result of approximate methods used in the past due to limited computational power. Users are always to implement the -correct option. This document explains how the -app none and -correct options in the &COMPARTMENT command affect the calculated…

  • MOSES, Statistic Calculation of Double Peak Jonswap Spectrum(-e_period)

    1. Overview

    The purpose of this document is to show what gamma values for 2JONSWAP spectrum MOSES calculate and what is reported when multiple periods are defined with an option "-e_periods". Multiple sea-states with varying mean periods are stored in the database for later use in statistic calculation.  After generating hydrodynamic pressure data, RAOs of the vessel is computed. Motion statistics for several…

  • Sacs_tow option in the automated tools reports RAOs as G forces, but they should be displacement

    The RAO type is set by the value in column 5 of the RAO line and are defined as Gravitational accelerations (G’s) when the value is ‘G’, and for displacement it should be "D".

    The MOSES output is for displacement, also referred to as motions.  The value in column 5 should be written as "D".

    This will be fixed in the next update.
