Sažetak
In this paper, the methodology of seaworthiness and stability analysis of a pontoon for holiday house
has described. A 3D model of the pontoon was modelled in the NAPA software to perform hydrostatic
analysis. It is necessary to emphasize the fact that hydrostatic analysis has been made for several
drafts and trims of pontoons. The hydrostatic analysis yielded data such as displacement, moulded
volume, longitudinal centre of buoyancy, the transverse metacentric height, change of displacement,
moment to change trim, and more. This part of the analysis also includes the loading scale from
which we can see the deadweight at a given draft. Further, it is necessary to make weight study to get
moulded displacement for pontoon for a holiday house. The pontoon also includes capacity tanks, so
it is necessary to know the accurate dimensions of the tanks and their position for further analysis.
It is necessary to know the exact geometry of the tanks because of the free surface effect. When
calculating the stability of the pontoon, it is necessary to determine the minimum metacentric height
and the maximum distance from the keel to the centre of gravity. Intact stability conditions must be
met for GM limit curves and also for KG curves. Intact stability criteria of the pontoon were tested for
four loading conditions: lightship, pontoon with 10% consumables without passengers, pontoon with
100% consumables with passengers, pontoon with 50% consumables with passengers. It is important
to emphasize that all tasks meet the stability criteria.
