Project Experience: Ship Loading and Unloading Operations Noise Study, Florida

The Challenge

Helping the Port of Miami respond to noise complaints from residents of Fisher Island. The noise stemmed from ship loading and unloading operations and was affecting these residents of high-rise condominium buildings located across a 600-foot wide channel from the Port.

The Strategy

HMMH performed a noise study and evaluated the complaints. The results showed that under some operating conditions, the noise environment at Fisher Island was less than ideal for residential land use. So we developed several strategies to alleviate the problem.

The Solution

Suggested mitigation measures included:

  • Converting the cranes to electric power
  • Implementing a cushioning system to reduce impact noise
  • Lowering the sirens from the top of the cranes to shielded locations and directing them downward
