Compliance Test of Discharged Water

Ensure compliance of discharged water with international conventions, supporting green global shipping.

Background and Basis of the Convention

Background and Basis of the Convention

Discharged water from ships, including ballast water, gray water, EGCS wash water and sewage water, can severely damage marine ecosystems if not properly treated.
The International Maritime Organization (IMO) has established strict standards through conventions such as the Ballast Water Management Convention, MARPOL 73/78, and VGP. Non-compliance may result in fines, detention, or port state control sanctions.

Frequently Asked Questions

Is your testing service limited to China only? Can you provide services at overseas ports?

No, we are not limited to China. We have established a service network covering major ports worldwide, enabling us to respond quickly to your testing needs across various shipping routes. You do not need to worry about diverting your vessel or waiting extended periods for testing. We recommend that you communicate your port call information with us as early as possible once the itinerary is confirmed, so that we can coordinate local resources in advance to ensure smooth testing.

What accreditations does your laboratory hold? Are your reports accepted by classification societies and Port State Control (PSC)?

Our reports are internationally recognized and accepted by major classification societies and PSC inspectors.

This is supported by the following three aspects:

International Mutual Recognition Accreditation: Our laboratory holds ISO/IEC 17025 (CNAS) accreditation and CMA certification, ensuring that our testing capabilities and management systems comply with international standards – the foundation for global recognition of our reports.

Full Recognition by Top Ten Classification Societies: We have obtained accreditation from ten major classification societies, including NK, DNV, ABS, LR, BV, CCS, and others. This means our test reports can be directly used for vessel certification, surveys, and compliance verification without the need for additional review.

Regulatory Compliance Assurance: Our testing methods strictly follow IMO conventions and the requirements of various port states, ensuring that our reports satisfy PSC inspectors' review criteria and help vessels clear port state inspections smoothly.

What are the common causes if a test result is non-compliant? Can you help with troubleshooting?

Yes, we can. We go beyond issuing test reports – we provide "testing + diagnosis" one-stop technical support to help you quickly identify the root cause and find solutions.

Specifically:

Root Cause Analysis: Our technical team can assist in analyzing the causes of non-compliance based on test data and the operational status of onboard equipment. For example, ballast water non-compliance is often related to accumulated sediment in ballast tanks, aging UV lamps, or sensor calibration drift. Non-compliance in sewage is commonly caused by aeration system malfunctions, insufficient chemical dosing, or insufficient retention time.

Corrective Recommendations: Once the cause is identified, we will issue a detailed corrective action report to guide the crew or shore-based support team in making targeted adjustments or repairs.

Re-testing Support: After corrective actions are completed, we can prioritize re-testing to help you obtain a compliant report as soon as possible, minimizing any impact on your vessel's schedule.
