Phase 1: Graving Dock Upgrade (2012)
In the first phase of this project, the client was upgrading a graving dock to support the construction of the world’s largest offshore oil rig. Due to dynamic conditions the 4’ foot thick slab failed, rising up 2-3 feet in the center from hydraulic pressure, necessitating urgent intervention. Concrete Cutting and Breaking (CCB) was tasked with wire sawing and slab sawing approximately 150,000 square feet of concrete. Our team expertly segmented the slab for efficient removal by the client.
Phase 2: Graving Dock Conversion (2019)
In 2019, the graving dock was sold to be converted into a tank storage facility. CCB was called back to manage the delicate removal of the entire slab. The operation required minimal vibration to prevent structural collapse and flooding, as we were working 60 feet below sea level.
To meet these challenges, we deployed wire saws and super-deep slab saws with blades reaching up to 91 inches in diameter that CCB designed and built ourselves. The slab consisted of some of the hardest aggregate in the world, heavily reinforced with steel. Despite these conditions, our team executed the task with precision and efficiency.
What set CCB apart in this project was our rapid mobilization and sustained on-site presence throughout the summer. We had a robust setup as we employed five wire saws and twenty slab saws, ensuring continuous and efficient operations.
