The +Gz-induced loss of consciousness curve [PDF]

Extreme Physiology & Medicine, 2013
+Gz-time tolerance curves were developed to predict when exposure to +Gz stress exceeds human tolerance resulting in neurologic signs and symptoms. The +Gz-induced loss of consciousness (G-LOC) curves were developed to predict when +Gz stress induces G-LOC. The G-LOC curves are based on a theoretical understanding of how acceleration affects underlying

The +Gz recovery of consciousness curve [PDF]

Extreme Physiology & Medicine, 2014
The limiting physiological envelope to extreme gravitational stress is defined by neurologic symptoms and signs that result from exceeding neurologic tolerance. The edge of the limiting envelope is defined by the complete incapacitation associated with acceleration (+Gz) induced loss of consciousness.

Method for ship’s rolling period prediction with regard to non-linearity of GZ curve

Journal of Theoretical and Applied Mechanics, 2016
The paper deals with the problem of prediction of the rolling period. A special emphasis is put on the practical application of the new method for rolling period prediction with regard to non-linearity of the GZ curve. The one degree-of-freedom rolling equation is applied with using the non-linear stiffness moment and linear damping moment formulas.

A Study on Characteristics of Rolling in Head Waves of a Vessel with Nonlinear GZ-curve

Journal of the Japan Society of Naval Architects and Ocean Engineers, 2012
In this study, the characteristics of rolling in head waves for a vessel with nonlinear GZ-curve, which includes parametric rolling, are investigated. Rolling is measured for systematically changed wave length and height under the same forward speed, which is service speed in heavy weather.

Assessment of Safe Loading Conditions for the SPCB Deck Crane Using Hydrostatic and GZ Curve Analysis

International Journal of Marine Engineering Innovation and Research
This study comprehensively assesses safe loading conditions for the Self-Propelled Crane Barge (SPCB) Deck Crane by integrating detailed hydrostatic calculations with righting-arm (GZ) curve analysis. At the designated summer draft of 2.75 m, baseline parameters—displacement (1 716 t), centre of buoyancy (KB = 0.765 m), transverse metacentre (KM = 2 ...

The Stability Analyze of KM. Rejeki Baru Kharisma of Tarakan – Tanjung Selor Route

Teknik, 2021
Ship stability that is not according to the IMO standard will make the ship capsize when operating. The purpose of this research is to determine the cause of the overturn in terms of the stability criteria of the ship.

A Methodology for Simply Evaluating the Safety of a Passenger Ship Stability Using the Index for the Intact Stability Appraisal Module

Sensors, 2022
To evaluate the safety of passenger ships’ stability, ten stability parameters should be calculated. However, since the process for calculating all stability parameters is complex without a ship loading program, a convenient methodology to simply ...

Analysis of the Relationship between GM and IMO Intact Stability Parameters to Propose Simple Evaluation Methodology

Journal of Marine Science and Engineering, 2021
Securing a ship’s safe stability is essential. Thus, monitoring the stability parameters of the IMO requirements is required to provide an alert about the risk of the safety of ships’ stability to the captain, officers, and the crew of a ship.

A quantitative methodology for evaluating the ship stability using the index for marine ship intact stability assessment model

International Journal of Naval Architecture and Ocean Engineering, 2021
IMO stability regulations include various stability parameters such as GM values. To assess the stability of the ships, we should check all stability parameters of the IMO requirements.
