Specialist fabricators of heavy and complex structural steel.


Ferry Hull 1

Client Name: DPTI

Year Completed: 2015

Innovative Methodologies: Manufacture technique was critical to achieving success on this complex project. Because Bowhill Engineering was able to be involved right from the start of the design process, we were able to work closely with the clients design team to coordinate the longitudinal connection of the hull and build the ferry complete at our manufacture facility (previously been road freighted to Morgan in two halves). The benefits to the client included structural integrity, coating integrity, accuracy, and conveniently allowing DPTI to continue using their Morgan Slipway for some 2 months longer.

Technical Challenges: Large components, transported via river channel to DPTI dockyard. Using a professional approach to this challenge factoring in an allocation for extensive temporary steelwork.

We designed this temporary steelwork together with our own engineering and drafting team to be able to launch the completed ferry at the river just metres from our manufacture facility. We treated the temp steel like part of the product and gave it the attention that it needed to achieve the accuracy. The careful coordination with regards to the logistics was the key to the successful launch, through the use of 3D modelling and simulation we were able to predict and plan the process to ensure a successful launch.

Coating Details: Highly scrutinised 3 coat system internal and external surfaces of the large modules.

Successful Outcomes: A slick methodology was the key to the success for this project, the large components that were being built on our site had to be sequenced carefully between fabrication and surface treatment. Bowhill’s facilities enabled the complete manufacture on the one site in an efficient and environmentally friendly way. This approach saw the amount of activities that were required on our client’s site drastically reduce in comparison to previous builds. A safer and much more convenient outcome for our client DPTI .
