Marine Specialties and Jobs

Wharf: Diamond wire sawing technology’s concrete and metal cutting capability and dependability both above and below waterline means marine contractors confidently turn to Bluegrass. When it is essential that the wharf dismantling, modification or demolition project maintains schedule and budget, Bluegrass delivers.

Mooring Dolphins: Bluegrass technicians and diamond wire saws successfully cut and dismantle mooring dolphins of all dimensions into sections sized for removal.

Ship Shaft: By mounting our underwater saws to the ship hull, we can cut rudder control shafts.

Pier and Port: On structural modification jobs involving pile cutting above waterline and underwater, often in high profile and time sensitive situations, the Bluegrass advantage is reliable custom-built equipment and competent operators who consistently deliver on schedule.
