Initial Concept, Build Specifications, Detailed Design and Fabrication Drawings
Our client required two 300-cubic-yard dump scows, complete with full design, engineering, and fabrication documentation to support construction. These vessels were intended for use in dredging operations, specifically to transport and dispose of aggregate and sludge materials collected from the seabed.
Allswater developed a robust 24.4-metre (80-foot) dump scow design featuring two segregated hoppers. The vessels were designed to be unmanned and tug-assisted, allowing them to be positioned as needed during dredging operations.
Working in close collaboration with the client, Allswater produced the initial concept, build specifications, detailed design and fabrication drawings. Finite Element Analysis (FEA) was employed to optimize structural integrity in high-load areas, ensuring durability and performance under demanding operational conditions.
Engineering and Fabrication Support
Allswater delivered a comprehensive fabrication package that included:
- Assembly and sub-assembly drawings
- Piece part details
- Nesting plans
- Weld schedules
- Stability assessments
- Support for regulatory compliance and operational safety
- Consideration for long-term maintenance and operational efficiency
This package enabled efficient construction and ensured consistency across both vessels. The first scow was successfully completed during the off-season, and based on its success, the client proceeded immediately with the construction of a second identical vessel using the same design and documentation.
The client’s decision to replicate the design for a second vessel highlights the effectiveness of the engineering approach and the value delivered through Allswater’s collaborative process.
