• Input of contingencies for cargo and heeling operations;
• Control of heeling operations;
• Overseeing of heeling process (ship s metacentric height, draught, list, trim, displacement)
• Printout of results of the training.

Functionalities of Trainee's WP Software.

The Trainee' s W P software enables the following functions at the time of generation of the vessel cargo plan:

• Calculation, generation and storage of the vessel cargo plan;
• Maintenance of the cargo documentation;
• Calculation of draught at fore, aft and midships;
• Calculation of list, trim and metacentric height;
• Generation of stability diagrams;
• Consideration of local strength for calculation of loading on decks, hatches and double bottom;
• Accounting for seawater density;
• Visual representation of results of embarkation- disembarkation or movement cargo operations;
• omparison of all parameters of trim, stability, global and local strength with permissible values;
• Automatic calculation of ice load as per the IMO demands and the RMRS regulations, considering actual loading of the vessel;
• Facility for printing out the whole set of cargo embarkation documentation for submission to port administration;
• Maintenance and storage of cargo log and preparation of official documents.

Stores and Ballast. Facility of accounting for dead stores in tanks; Detailed data output to printer; Facility to input level, weight or volume values; Display of tank layout in two projections; Indication of free surface allowances for each tank; Storage of initial variant of the ballast layout in memory; Optimization of quantity and positioning of the ballast by trim, list and metacentric height Ship s stability monitoring. Simulator TGOS-2006 allows the trainees : To carry out practical heeling using facilities available onboard, by : -receiving ballast in ballast tanks; -receiving earlier weighed cargos; -turning and hoisting of the shipboard derrick booms; To automatically process data obtained during the heeling practice, including auto selec- tion of reliable values, estimation of quality of metacentric height measurement and admissibility of obtained results as per the RMRS demands. Ship s flood ability. There is a module calculating the ship s emergency condition, including : Generation of variants of typical ship damages assuming presence of seepage water for any combination of ship s compartments; Saving of ship s damage variants in the database; Calculation of ship s emergency condition with all variants of flooding for every loading option; Comparison of ship s characteristics in emergency condition with IMO demands and norms of the RMRS; Visual monitoring of the ship s emergency condition, including 3D representation of the ship s hull and affected compartments; Generation of the ship s emergency condition report; Calculation of trim and stability of the damaged ship for any combination of affected com- partments; Comparison of all trim and stability parameters with criterions of the RMRS. Ship's seagoing ability. Ship seagoing tasks are implemented for the following rough sea criterions : Side and bottom slamming; Deck flooding; Screw acceleration; Pitching and rolling resonance; Parametric resonance; Lost of stability and maneuverability in case of following seas; Rolling; Vertical accelerations. Auxiliary tasks. Generation of the ship s loading statement; Generation of step-by-step ballast amendment procedure as per IMO resolution A 868 (20); Correction of loading process depending on the current status of the ship. OPERATION MODELING Hardware-software system simulator enables modeling of the following tasks : Automatic collection of values of measured parameters at the time of practical heeling, to determine the metacetric height value at the berth and at the anchorage; Automatic estimate of quality of practical ship heeling, display of data pertaining to measured parameters on the onboard PC monitor and printing out of the same; Automatic draught measurement; Automatic heel measurement. Hardware-software system simulator enables implementation of six mathematical models: Mathematical model of a vessel (multipurpose dry cargo vessel) enables operation with the following types of cargos: - container (by bays and tiers); - general; - timber; - bulk (including grain); Mathematical model of a vessel with horizontal cargo processing (Ro-Ro) enables hand- ling of wheeled transport; Mathematical model of the automated system of measuring actual ship stability enables : -carrying out practical heeling and simulation of various degrees of accuracy of para- meters measurement; -automatic assessment of quality of the practical ship heeling with view to determine actual metacentric height of the ship at a pre-set sea state, wind force and gauging error. The simulator also enables prompt changing of of cargo loading processes and stability measurements. Instructor from his work place can input various amend- ments on displacement, metacentric height and trim data. The simulator enables the following variants of contingency modeling at the time of loading operations : unexpected heel (may by caused by uneven loading or erroneous ballasting); ship s susceptibility to roll (due to presence of dangerously vast free surfaces). The contingencies are set from the instructor s work place, either one after another or all together.
