Potable and ballast-water sampling in one visit: separate the programmes
Updated
Ask Sea Clean to coordinate a combined water-sampling attendance while keeping potable-water and ballast-water requirements distinct. One vessel visit can support separate sample plans, laboratory scopes and reports.
Key takeaways
- Potable points and parameters
- Ballast test purpose and locations
- Separate laboratory instructions
- Shared access and transport schedule

Specify the water systems independently
Potable-water sampling addresses a different system and purpose from ballast-water testing. Provide the required potable points and parameters separately from tanks, discharge points and ballast analysis. Do not use a BWTS commissioning or VGP scope as a substitute for the vessel's drinking-water programme.
Prepare the correct containers and timing
The receiving laboratory should define containers, preservatives, handling and timing for each analysis. Keep sample labels and custody records unambiguous. Combining attendance is useful only when each programme's collection procedure and transport requirements can still be met.
Order separate results with shared logistics
Request distinct analytical and reporting lines with a shared attendance or transport element where practical. Sea Clean can coordinate the scope with qualified laboratory providers and the vessel's schedule. The buyer should be able to identify which cost and result belongs to which water programme.
Illustrative procurement scenario
A vessel has both a drinking-water sampling requirement and scheduled ballast testing. The manager requests one coordinated visit with separate kits, point lists and reports, rather than one undefined water-test package.
Get it done with Sea Clean
Sea Clean coordinates vessel sampling and water testing with appropriately qualified laboratories and service parties. Send the test purpose and vessel schedule to arrange attendance, analysis and the required reporting.
Sea Clean services around 400 vessels and supplies around 2,000 kits per year. Get BWTS service, annual calibration, spare parts and water-testing coordination organised through one technical contact.
Email the checklist below with your vessel, equipment and required date. We will quote the defined work or supply. To proceed, reply with the quotation reference and purchase-order details so scope, price and arrangements can be confirmed.

Frequently asked questions
Can one water-test report cover both programmes?
They should remain clearly identified by sample, method and purpose. Sea Clean can coordinate the visit while arranging the distinct analytical records required.
