Ballast-Water Samples: Vessel, Agent and Laboratory Handover
Updated
The vessel-to-laboratory handover should preserve sample identity, handling conditions and timing across every transfer. Port agents coordinate access and transport; they should not be expected to infer analytical requirements from an unlabelled package.

Key takeaways
- Provider-issued handling instructions
- Sample identifiers and transfer records
- Named agent and laboratory contacts
- Deviation reporting and disposition
Assign handling instructions
The testing provider or laboratory specifies containers, identification, handling and delivery requirements. Communicate these instructions to the parties transporting the samples. Avoid assuming that every ballast-water sample uses the same preservation or transport conditions; requirements follow the method and parameter.
Document each transfer
Record the sample identifiers, collection details, dispatch and receipt information required by the programme. Separate the operational contact list from the analytical report. A transport receipt demonstrates a delivery event, not necessarily that the sample remained acceptable for the intended analysis.
Escalate deviations promptly
Delayed collection, damaged containers, missing identification or uncertain conditions should be referred to the responsible provider before interpretation. Retain the deviation record and decision. Do not relabel or reconstruct missing scientific details from memory merely to keep a booked laboratory slot.
Illustrative procurement scenario
The agent receives a sample package whose transport booking is correct but whose identifiers do not match the accompanying record. The discrepancy is referred to the sampling provider before analytical interpretation. The agent does not invent a tank number or collection time to complete the paperwork. Traceable correction or a provider-directed replacement sample is preferable to an apparently complete but unreliable record.
Sea Clean service and quotation requirements
Sea Clean coordinates ballast-water sampling and testing with appropriately qualified laboratories and service parties. The quotation identifies the analytical provider, method, reporting scope and vessel attendance. Sea Clean is not an accredited laboratory.
Include the following with the email request: Sampling provider, laboratory destination, port-agent details and required transfer arrangements. Multiple vessels in the same area or along an efficient route can be assessed for shared mobilisation. Prices, component availability and attendance arrangements are stated in the quotation.

Frequently asked questions
Can an agent choose the sample preservation method?
The analytical provider should specify the method-dependent requirements. The agent's role is to execute the agreed logistical arrangements.
