2D Wire Frame FE-Analysis:
A 2D wire frame is undertaken to compute large structures in FE-Analysis. As an example, below is the hatch cover of a Multi Purpose vessel. This model can be rigorously analysed for all scenarios that occur when transporting heavy loads.
The re-creation of the hatch-cover, tween-deck or the lower-hold of a vessel is commonly undertaken at MBM to confirm the structural integrity to transport cargo’s in sea going conditions.
Below are the 4 stages of the analysis:
• Stage 1 – Drawings are acquired. |
| Scantling drawings of hatches used to define the model. |
• Stage 2 – Confirmation of dimensions from drawings with a Hatch Survey on the vessel. |
The vessel under analysis will be visited by the Naval architect to confirm the scantling drawings provided. This is to ensure:
a) The drawings provided correspond to the hatch under analysis.
b) Modifications, corrosion, erosion, cracks, or imperfections are recorded.
A full set of hatches can be created and analysed as one- |
Or
Singular pontoons can be analysed to speed up the computation process- |
Or
Sections of the hatch cover (solid 3D model) can be re-created i.e. a transversal - |
• Stage 4 – The model is subject to state of the art FE-Analysis. |
