The results show that nonlinear finite element analysis most accurately simulates real-world loading conditions. ) roof while it is floating without damaging the floating roof. This calculation would mean that the pontoon boat could carry about 2. 2 x 5. The key steps are calculating the hydrostatic properties of the floating barge based on its weight and centers, determining if pontoon or general criteria apply, and plotting the righting arm curve from cross Description: This popular spreadsheet automatically computes trim, list, forward port and starboard draft s, aft port and starboard draft s, GMs (metacentric height s: transverse and longitudinal). 000 COMPRESSOR ROOM SWITCHBOARD / TRANSFORMERS AUXILIARY SWITCHBOARD ROOM MAIN SWITCHBOARD / TRANSFORMER ROOMS 12x12= 144 square feet x 28 = 4032 lbs of buoyancy required. Stability is important for safe barge operation and is regulated by the IMO Code. In addition to these parameters, by implementing the calculated data of mass and sectional properties of the bridge truss-work components, the simplified beam model of the bridge is built in Abaqus. Method 2. GM min = 0. 6m up from the bottom and 20 mm aside from the vertical centreline.
