Meeting U.S. Marine Engineering Standards


In early 2023, BRUCE’s SGV‑1000 vibratory hammer was deployed in a U.S. marine bridge foundation project.

Designed to meet stringent performance and environmental standards,

it enabled the contractor to achieve over 60% faster sheet pile installation while minimizing disturbance to marine life.

1. Technical Insights: What Makes the SGV‑1000 a High Performer?

  • Equipped with dual counter-rotating eccentric weights, generating up to 3,045 kN of centrifugal force.

  • Adjustable frequency and amplitude via remote control ensures precise and efficient soil compaction.

  • Integrated hydraulic clamp system enables fast changeover between sheet & tube piles, boosting productivity.


2. Project Case Study: Efficiency in Action

  • Site Conditions: East Coast marine construction site with sandy-silt seabed and tidal variance.

  • Pile Type: 1,020 mm diameter steel sheet and tube piles

  • Performance Outcome:

    • Pile driving cycle: less than 2 minutes per pile (vs. 5–6 minutes by traditional impact methods)

    • Clamp transition time: under 30 seconds, enabling continuous workflow


3. Environmental & Operational Advantages for U.S. Contractors

  • Lower noise and minimal vibration transmission—crucial for compliance with U.S. marine sound limits.

  • Operator Safety and Control: Remote monitoring with LED diagnostics reduces manual exposure and improves stroke precision.

  • Flexible Rig Mounting: Compatible with fixed-leader, crane-suspended, and U-type configurations tailored for U.S. offshore or near-shore operations.


4. Performance Comparison: Vibratory vs. Impact Hammers


Feature SGV‑1000 Vibratory Hammer Traditional Impact Hammer
Installation Time ~2 min/pile 5–6 min/pile
Noise & Vibration Low continuous vibration High impulse, environmental risk
Changeover & Flexibility Fast clamp conversion Manual, slower
Operation Control Remote + diagnostic monitoring Manual or semi-automated

5. Frequently Asked Questions (FAQ)


Q: Is a vibratory hammer appropriate for both driving and extracting piles?
A: Yes—BRUCE’s SGV‑1000 uses a robust clamp and line pull system that handles both installation and extraction efficiently.

Q: Can the SGV‑1000 meet U.S. marine environmental standards?
A: Absolutely. Its continuous vibration profile and optional noise suppressor kit make it compliant with U.S. underwater acoustic regulations.

Q: What excavator classes are compatible with this vibrator?
A: The SGV‑1000 is typically installed on excavators weighing between 20–50 tons with short hydraulic hoses and quick-connect systems.
