From safety point of view it is essential to carry out strength and stability calculations of ships during loading operations. To make these calculations by hand without using a Computer is difficult, time consuming and open for mistakes. Since February 1998 International Maritime Organization (IMO) obliged ship owners to accommodate a computer and relevant software application able to carry out strength calculations for bulk carriers having length above 150 m. Afterwards this regulation was expanded on 1st of July 1998 under the scope of the rule coded as IACS UR S1 for all ships having length above 65 m. With the rapid proliferation of personal computers and obligation to make longitudinal strength calculations by computers, ship masters have been willing to use software applications also for stability calculations.
Delta Marine together with its solution partner Mesh (Mesh Engineering & Software Co.) provides a ship loading software which would meet precisely the requirements of the customers. Named as DeltaLoad, this software application is customized based on particulars of the ship such as type, dimensions, compartmentalization, etc. Basically DeltaLoad is a tool to carry out draft, trim, list, longitudinal strength, intact and damaged stability calculations interactively with the user as result of virtual loading operations of standard loads (ballast, fresh water, fuel oil, lubrication oil, etc.) and nonstandard loads (cargo). In the meantime documents and information such as draft survey report, loading report, hogging/sagging calculations, loading/unloading optimization can be produced using the software. DeltaLoad is also capable to present integration interface to many different tank level measurement systems to get tank filling level information constantly online.
DeltaLoad is a software product which can respond the request for digital intact and damaged stability calculation in ships either operated or chartered by to major oil companies, meet the requirement to run online and integrated with the tank level measurement system in parallel with the technological improvements in automation applications and -especially for container ships- fulfill the need to use a software application for loading and automation operations in order to maximize the amount of cargo and maintain close cooperation with container terminals.
Data Entry
The loading data can be entered manually from the compartment list or from the selected compartment in the graphical interface. In case that an electronic tank measurement system exists on the ship, it is possible to establish a communication link between this system and DeltaLoad via an online communication add-on module that ensures the interaction of two systems through the exchange of data either at desired times or continuously.
Intact Stability
When a loading data is changed in a compartment DeltaLoad is able to calculate automatically the new equilibrium status (as draught, trim and list) of the ship. The compliance of the criteria, which is calculated from the static stability curve, is checked with IMO criteria.
Damage Stability
Vessel Stability Calculation
The compartments that can be damaged according to the damage standards determined in Marpol or IBC Codes are automatically damaged at given loading condition and the criteria are checked for every damage case. This feature provides damage scenarios without any requirement of expertise about damage stability on user side.
Longitudinal Strength
When a loading data is changed in a compartment, the new equilibrium status (as draught, trim and list) is automatically calculated and weight and buoyancy distribution is generated according to the new condition. The load distribution is calculated from the difference of weight and buoyancy distribution. Calculating the integral of the load distribution gives the shear force while calculating the integral of the shear force gives the bending moment. The calculated shear force and bending moment values are compared with the allowable values given by the classification society for the control points.
