VSP 2018 Operations Manual

5.2.1.1.2 Within 30 Minutes (08)
The free HALOGEN residual level must be adjusted to at least
2.0 MG/L (ppm) and the pH adjusted not to exceed 7.8 within
30 minutes of the start of the bunkering and production processes.

5.2.1.2 Monitoring

5.2.1.2.1 Bunkering Pretest (08)
A free HALOGEN residual and pH test must be conducted on the
shore-side water supply before starting the POTABLE WATER
bunkering process to establish the correct HALOGEN dosage.

The results of the pretest must be recorded and available for review
during inspections.

5.2.1.2.2 Bunkering/Production Test (08)
After the free residual HALOGEN level of at least 2.0 MG/L
(ppm) and pH level not exceeding 7.8 have been reached, the free
residual HALOGEN and pH monitoring must be performed at
least hourly during the bunkering of POTABLE WATER.

After the free residual HALOGEN level of at least 2.0 MG/L
(ppm) and pH level not exceeding 7.8 have been reached, the free
residual HALOGEN and pH monitoring must be performed at
least once every 4 hours during the bunkering of POTABLE
WATER.

A test kit must be available for testing free HALOGEN levels and
pH.

Test kits must be accurate to within 0.2 MG/L (ppm) for
HALOGEN and must have a testing range of free residual
HALOGEN normally maintained in the POTABLE WATER
system. Test kits for pH must be accurate to within 0.2.

5.2.1.2.3 Records (08)
Accurate records of this monitoring must be maintained aboard for
12 months and must be available for review during inspections.

5.2.1.2.4 Analyzer-Chart Recorders (06)
HALOGEN and pH analyzer-chart recorders used in lieu of
manual tests and logs must be calibrated at the beginning of
bunkering or production, and the calibration must be recorded on a
chart or in a logbook.
