Hatch Sealing & Unsealing Services

At USAMS – Unique Solution Association for Marine Surveying, we provide professional Hatch Sealing & Unsealing Services to ensure the security and integrity of cargo holds during maritime transportation while providing independent and reliable documentation of cargo hold status from the completion of loading operations until arrival at the discharge port.

These services are essential in confirming that cargo spaces remain properly closed, secured, and protected from unauthorized access throughout the voyage, providing confidence to cargo owners, charterers, receivers, and all other interested parties.

Our surveyors attend onboard vessels upon completion of loading operations to inspect hatch covers, verify that they are properly closed and secured, and apply numbered security seals where required. Seal numbers and locations are carefully recorded and documented in official reports. Upon arrival, we verify the integrity of the seals and supervise their removal when requested by the relevant parties.

Our Services Include:

Hatch Cover Sealing

Application of numbered security seals to hatch covers upon completion of loading operations.

Seal Verification & Unsealing

Verification of seal integrity and compliance with recorded seal numbers prior to unsealing.
