Vessel lay-out optimalization
Saltwater was contracted to execute various engineering tasks related to the conversion of a cable laying vessel.
Matching vessel lay-out to ever-developing offshore wind market
The most impactful task was equipping the vessel with an existing A-frame. The integration scope consisted of verifying the structural integrity of the original A-frame, repeating the strength calculations for the modified A-frame and verifying additional load cases that were requested by the client. The scope of the analysis was limited to strength verifications, no structural modifications were required. To complete the above the following checks were executed:
- Splash zone checks
- Snap loads
- Added mass on CBT (cable burial tool)
- Hydraulic cylinder misalignment (30mm)
- Buckling verification
Purpose-built foundation design
The A-frame has been positioned on the centerline on the aft of the vessel, a purpose-built foundation was designed, and strength has been verified. Upon completion of the design, a set of construction drawings were delivered. The scope of work for this partition consisted of the following items:
- Design and structural verification of foundation
- Structural verification of vessel local structure
- Construction drawings of A-frame foundation
- Delivering plans for class approval
Splash coaming
To improve safety and workability on the aft deck, the vessel has been equipped with a bulwark/splash coaming along the sides and partially on the aft. The coaming has been designed such that it has sufficient openings for mooring, and freeing ports where needed. The coaming design does not contribute to the longitudinal strength of the vessel.
The scope of work for this partition was limited to the following:
- Design and verification of bulwark/coaming according to class regulations
- Strength analysis of fairlead/chock integration
- Construction plans
