Initial Design is an integrated suite of programs aimed at hull form designers and Naval Architects It incorporates functions for hull form definition & fairing, appendage modeling, internal arrangement and analysis of hydrostatic and hydrodynamic characteristics The application consists of the next five modules: The Lines module is a hull fairing tool based on traditional methods that can be used to create virtually any form of marine vehicle including multi-hulls, chined and asymmetrical hulls The hull form is initially represented as a loosely connected mesh of curves that is used to create a network of 3D surface patches The Surface module principally used to define a product model of the outer surfaces of the main hull and its appendages At its core is a 3D solid modeling kernel (ACIS) that can be used to create many additional features for ships and other structures The Compartment module facilitates the quick definition of transverse bulkheads, longitudinal bulkheads, decks, compartments and superstructure This shares the same framework as the Surface module The Calc module offers ship designers a comprehensive toolkit of naval architectural assessment functions It encompasses the calculation of hydrostatics, loading conditions, intact and damage stability, critical KGs, longitudinal strength, tank calibration and damage stability assessment The module uses both deterministic and probabilistic methods The Hydro module is used to predict the hydrodynamic performance of vessels via the calculation of the vessels powering, maneuvering and sea-keeping characteristics This shares the same framework as the Calc module Lines • Lines • Hull Form Surface & Compartment • Internal Subdivision • Superstructures • Other Structures Calc & Hydro • Hydrostatic Calculations • Intact & Damage Stability Calculations • Hydrodynamic Calculations The ship design procedure using the Tribon – Initial Design modules For more details about Tribon M2 product see the Tribon M2 User’s Guides documentation or visit the Tribon Solutions Corporation web page at www.tribon.com Skoupas, S (Dec 2003) An Example of Preliminary Ship Design using TRIBON M2 SDL -

NTUA EXAMPLE – Damage Stability • -31- DAMAGE STABILITY The example ship is a reduced freeboard B-60 bulkcarrier according to the Int Load Line Convention of 1966 Based on this the ship must be able to survive flooding of any compartment, with an assumed permeability of 0.95, thus in damage condition to stay afloat at satisfactory equilibrium condition Because the ship is over 225 m in length, the machinery space is also assumed floodable, but with a permeability of 0.85 The ship after damage must comply with the requirements of the SOLAS 1992 Part B-1 Reg.25-1 Cargo Ship Rules In this approach the survival capability is assessed through comparing the Required Subdivision Index, R, and the Attained Subdivision Index, A The condition to be satisfied is that A > R To calculate A-Index, it is necessary to perform damage stability calculations of the traditional kind for all possible combinations of compartments assuming an initial KG equal to the limiting KG obtained from the appropriate intact stability criteria (here IMO A.167) at the draft being used The damage scenarios for the ship in question are 522 for each draft PROBABILISTIC DAMAGE STABILITY Probabilistic Data Heeling to starboard Main Particulars Subdivision Length Length b.p Breadth Depth Aft end from Origin Subdivision Loadline Lightest Service Draft Transverse Bulkheads 280.075 270.000 45.000 23.800 4.500 17.519 11.431 metres metres metres metres metres metres metres ID T11.2 T38.4 T62.2 T86.85 T111.5 T136.15 T160.8 T185.45 T210.1 T234.75 T258.55 Position from AP metres 11.200 38.400 62.200 86.850 111.500 136.150 160.800 185.450 210.100 234.750 258.550 Skoupas, S (Dec 2003) An Example of Preliminary Ship Design using TRIBON M2 SDL -
