Project description:

For a beaching operation the HD3 Plough of VBMS is pulled backwards towards the beach. To support the plough, a beach skid needed to be designed and fabricated. The beach skid exists of the following main specifications:

• Main dimensions: approximately 10m Length x 1.9m Width.
• Weight approximately: 3.5 tons.
• 1 towing point with a SWL of 90 tons.
• 2 shafts to connect with the plough share.
• Hydraulic system to retract the 2 shafts.

Scope:

Our sister company, Offshore Independents, performed the structural engineering support:

• A conceptual design of the skid was supplied to Offshore Independents which formed the basis of the analysis.
• The skid design was analysed in ANSYS and further refined into a detailed design.
• According to AISC ASD 9th Edition and ISO EN 10025 regulations.
