Frequently Asked Questions
How often is testing required?
CHC opacity testing is typically required on a periodic schedule, often described as biannual. The exact frequency depends on vessel type, engine classification, and current CARB regulations. We can help confirm what applies to your vessel and operating area.
What if a vessel doesn’t pass?
If a vessel does not meet opacity requirements, you’ll receive clear documentation of the results along with guidance on next steps. After any necessary maintenance or adjustments are completed, a retest can be scheduled.
How far in advance should I schedule?
We recommend scheduling as early as possible, especially as regulatory deadlines approach. During peak compliance periods, availability can become limited. Booking ahead helps ensure you secure your preferred timeframe.
Do you test fleets?
Yes. We work with operators managing multiple vessels and can coordinate fleet testing schedules to minimize downtime and streamline compliance across your operation.
