Industries We Serve

Marine Demolition and Subaqueous Cutting Solutions

Marine demolition projects take place in conditions that test both equipment and people: current, turbidity, depth, tidal scheduling, and strict environmental oversight. The structures being removed (piers, caissons, sills, mooring dolphins, ship components) are typically large, submerged in whole or in part, and surrounded by active maritime operations that cannot be interrupted.

Bluegrass Bit has been serving the industry as a leading marine demolition company since 1979, offering expert underwater concrete and metal cutting services. Our equipment is custom-designed and fabricated in our own machine shop (including our patented underwater diamond wire saws) and our operators are trained and certified to work in marine environments. Our innovation, problem-solving, and safety record reinforce our worldwide reputation for excellence as a marine demolition company.

Why Choose Bluegrass Bit for Marine Demolition?

Choosing Bluegrass Bit as your marine demolition contractor means the job is supported by more than 45 years of experience on port, wharf, bridge, and offshore projects. We stand behind our excellent safety record and our reputation for completing marine projects on schedule, two standards that matter as much in the marine industry as anywhere we work. Distinct advantages Bluegrass brings includes:

Specialized Marine Demolition Contractors for Complex Infrastructure

As leading marine demolition contractors, we understand that maritime projects require more than just standard equipment; they require a rigorous commitment to safety and environmental stewardship. Cutting in high-profile and schedule-driven situations, above and below waterline, in challenging marine environments is a core Bluegrass capability. Our advantage is reliable, custom-built equipment and competent operators who consistently deliver on schedule. Bluegrass technicians are trained and certified for marine work, carrying OSHA, First Aid, BOSIET, and TWIC Card certifications in addition to site-specific qualifications.

Our Core Marine Capabilities

Mooring Dolphin Removal

We cut and dismantle mooring dolphins of all dimensions, sizing sections for removal by crane. Our low-vibration cutting method protects adjacent berth structures and allows port operations to continue during the project.

Wharf and Berth Removal

Wharf dismantling and berth removal projects require coordination with active port operations and strict adherence to environmental and navigational schedules. Bluegrass delivers: our equipment is reliable, our operators are experienced, and our project management is focused on maintaining schedule and budget.

Sill and Caisson Cutting

Submerged sills and caissons require reliable underwater cutting systems and experienced operators. Our custom-built underwater diamond wire saws are deployed by divers or ROV and operated from the surface, providing consistent performance at depth and in low-visibility conditions. Our slurry and debris management systems maintain environmental compliance throughout.

Vessel Component Cutting

By mounting our underwater saws directly to the ship hull, we can cut rudder control shafts and other internal ship components that require access without drydocking. For complex interior cutting — such as our work on the NS Savannah, the world’s first nuclear-powered merchant ship — we design and fabricate customized equipment on site to address the specific geometry and constraints of the job.

Advanced Marine Demolition Services

The cornerstone of our success in marine demolition services is our fleet of custom-built diamond wire saws engineered to emphasize dependability, ease of operation and simplicity of deployment. Unlike conventional methods, our saws are designed for reliability in high-current and low-visibility conditions. By mounting our ROV-compatible underwater saws directly to the structure, we deliver a precision cut every time.

Expert Marine Demolition: Case Studies in Excellence

Bluegrass has a proven track record of solving the “impossible” in the marine sector. Our work at the Port of Los Angeles and the Copano Bay Bridge demonstrates our ability to deploy as a specialized marine demolition contractor to handle pile cutting and structural sectioning under strict environmental regulations.

We don’t just provide equipment; we provide a comprehensive demolition strategy that minimizes downtime. From the Blount Island Sill Removal to the Nuclear Ship Savannah Renovation, our competent operators consistently deliver on schedule, maintaining project budgets since 1979.

Marine Demolition FAQs

Can your equipment handle both concrete and metal cutting underwater?
Yes. Our diamond wire saws are engineered to cut through heavily reinforced concrete, solid steel ship shafts, and composite marine structures with equal efficiency, regardless of water depth or turbidity.
As a professional marine demolition company, we use non-percussive cutting methods like diamond wire sawing. This reduces vibration and noise, minimizing the impact on local marine life and surrounding structural integrity compared to traditional hammering.

Our marine demolition contractors frequently work on piers, wharfs, mooring dolphins, caissons, bollards, and bridge footings. We also provide specialized cutting services for ship renovations and offshore platform segmentation.
