Subsea Diamond Wire Saw
In bridge foundation demolition, port and harbor renovation, offshore structure maintenance, and underwater obstruction removal projects, cutting large-diameter steel pipe piles, reinforced concrete piles, and steel-concrete composite structures remains a significant technical challenge.
Conventional underwater cutting methods may involve risks associated with close-range operations, limited working space, difficult equipment positioning, and cutting instability caused by environmental conditions. These challenges become even greater when dealing with large-diameter, high-strength piles in deep water, strong currents, or low-visibility environments.
To address these challenges, BEIYI introduces its new Hydraulic Diamond Wire Saw Pile Cutter, providing a specialized equipment solution for underwater pile removal, offshore structure modification, and complex submerged cutting applications.

Product Description
Stable Clamping, Low-Vibration Cutting & Remote Operation
The BEIYI Underwater Diamond Wire Saw features a pile-clamping frame designed to fit securely around the pile, helping minimize equipment movement and misalignment during cutting. This design accommodates vertical and inclined piles under suitable operating conditions.
Powered by a hydraulic motor, the diamond wire performs continuous abrasive cutting, offering low vibration, reduced noise, and smooth cutting surfaces. This helps minimize disturbance to surrounding structures and remaining pile sections.
The equipment also features a wireless remote control system, allowing operators to control cutting operations from the water surface, shore, or vessel, depending on site conditions. This reduces the need for divers to remain close to the cutting area and improves operational control in challenging underwater environments.

Multiple Applications for Complex Underwater Cutting
The BEIYI Hydraulic Diamond Wire Saw is designed for underwater pile cutting, removal, and modification in bridge, port, harbor, and offshore engineering projects. Equipment selection can be tailored to pile dimensions, material properties, and site conditions.
01 | Bridge Foundation Demolition & Underwater Obstruction Removal
Suitable for bridge renovation, existing pile removal, and underwater pile obstruction clearance.
The Underwater Wire Saw can be configured for cutting steel pipe piles, steel casings, and reinforced concrete piles, helping reduce vibration-related disturbance to surrounding structures.
02 | Port, Harbor & Offshore Engineering
Suitable for port and harbor foundation modifications, offshore platform pile removal, and compatible pile-cutting applications in offshore wind projects.
For suitable subsea applications, the Subsea Diamond Wire Saw provides a hydraulic cutting solution for the removal and modification of underwater foundation structures.
03 | Steel-Concrete Composite Structure Cutting
For steel-concrete composite piles, concrete-filled steel pipe piles, and steel casings filled with concrete, the diamond wire performs continuous abrasive cutting through suitable materials.
Diamond Wire Cutting Underwater offers a practical approach to these complex structures. The cutting configuration must be determined according to steel wall thickness, concrete strength, structural design, and project requirements.
04 | Challenging Underwater Working Conditions
In deep-water environments, strong currents, low visibility, and confined working spaces, equipment positioning and stability are essential.
The pile-clamping frame helps secure the cutting system to the pile and reduce movement during operation.
The Diamond Wire Cutter Subsea configuration can be evaluated according to water depth, current conditions, pile dimensions, and other site-specific requirements to determine a suitable cutting solution.
