On Regulatory Framework of Direct Stability Assessment

Contemporary Ideas on Ship Stability, 2019
Direct assessment of stability, including model tests and numerical simulations, is the ultimate way to evaluate the risk of stability failure for an unconventional vessel. That is why direct assessment is considered to be the highest tier of the second generation of intact-stability criteria, that are being developed by IMO.

Direct Stability Assessment for excessive acceleration failure mode and validation by model test

Ocean Engineering, 2019
Abstract The excessive acceleration is one of five stability failure modes for intact stability being discussed at IMO. The trial calculation for Direct Stability Assessment (DSA) and the model test have been carried out to verify two prediction methods of ship motions in the short-crested irregular waves for DSA.

Model Characteristics and Validation Approach for a Simulation Tool Supporting Direct Stability Assessment

Contemporary Ideas on Ship Stability, 2019
Significant challenges exist in the validation and formal acceptance of dynamic stability simulation tools, which can have a limiting effect on operations or concept design due to a need for conservatism. These challenges primarily consist of validation metrics and criteria, uncertainty characterization, and defining the scope of conditions (both ...

Comparison between fast direct methods for transient stability assessment

2012 IEEE Electrical Power and Energy Conference, 2012
Direct methods were developed to reduce computation time of transient stability assessment. Each method has its advantage and its own algorithm, which raises some differences between them. A new method was developed for providing the mathematical proof for the RAte of Change of Kinetic Energy (RACKE) method, yet become another direct method to compete ...
