Load Editor is an interactive interface through which you can quickly access certain commonly-used GHS features. For example, with a single keystroke you can change the loading of a tank and instantly observe the result of the change relative to a specific set of stability criteria.
Load Editor has two applications. One is the design evaluation of a vessel's stability, where various loading combinations are being investigated to determine maximum cargo loading or to explore dangerous combinations of partial loads. The other application is in the actual operation of a vessel to monitor the stability and strength margins related to a loaded condition (see GLM).
The Load Editor screen resembles a spreadsheet where each load item is represented by a line on the screen. Pressing the arrow keys moves the visible marker about on the screen, thus enabling you to point to any item and make changes. Loads can be entered as percentage full; volume or sounding; or by actual weight or percentage present for non-liquid loads.
The top of the screen is dedicated to showing the vessel's drafts, trim, displacement, overall CG, GM, maximum VCG, and VCG margin which change instantly in response to the operators inputs. The bottom of the screen shows profile and plan views of the vessel with tank boundaries and weight locations. Longitudinal bending stress and deflection are computed by pressing a key which temporarily brings in the LS module. The deflection so computed can even be retained and reflected in the draft readings.
Whether in the architect's office or on board a vessel, Load Editor is an efficient and accurate tool for working out the stability and strength margins.
