Case Studies – Bullitt

Brief

To turn the ballast system concept design into a workable system comprising of four tank volumes with fully–automated pick up, transfer and discharge – all integrated into the current GA of the vessel.  

Approach

Working alongside Pure, Judel/Vrolijk & Innovative Structural Design, BMComposites assisted and completed the final design layout for the entire system. All composite components were constructed in our purpose-built facility.  Ultra-lightweight CFRP parts were produced with the assistance of state-of-the-art technology such as 3D scanning, 3D printing and CAD CAM CNC. 

The system setup required special attention to detail for the scoop intake – to fill the tank volumes via a controlled master pump and distribute the necessary water volume as required for the chosen trim.  Then, at the right time, it was necessary to transfer several tons of water to the opposite tank in less than 6 seconds. The physical forces resulting from these processes can have a catastrophic impact on the new and surrounding structures if not designed and installed with complete precision.

    The Result

    BMC worked closely with the Captain, Designers, Engineers and sub-contractors to manage the entire process from initial briefing to installation and final commissioning. SY Bullitt won IRC Class 1 in the 2023 Middle Sea race in its first outing after the refit.
