VSP 2018 Operations Manual

6.2.1.2 In Port

6.2.1.2.1 Drained or Switched to Recirculation (10)
Before arriving to a port or HARBOR, the RWF must be drained
before the vessel reaches the 20-kilometer (12-mile) mark or any
point of land-based discharge as detailed in section 6.2.1.1.1 and it
must remain empty while in port or at anchor.

OR

The RECREATIONAL SEAWATER filling system must be shut
off 20 kilometers (12 miles) before reaching the nearest land or
land-based discharge point, and a recirculation system must be
used with appropriate filtration and halogenation systems.

6.2.1.2.2 Halogen and pH (09 C)
When switching from flow-through operations to recirculation
operations, the RWF must be closed until the free residual
HALOGEN and pH levels are within the acceptable limits of this
manual. The sample must be taken from the body of the RWF, not
from the pump room.

While the RWF is closed, batch HALOGEN and pH control
chemicals may be used to obtain ADEQUATE free HALOGEN
residuals and pH levels in a more-timely manner. Sufficient
time should be allowed before opening the RWF for use to
ensure proper mixing of batch chemicals.

6.3 Recirculating RWFs
(See individual sections for additional requirements for whirlpools and SPA
POOLS. See Annex 13.8 for requirements for BABY-ONLY WATER
FACILITIES.)

6.3.1 Operation

6.3.1.1 Fill Level and Turnover Rates (10)
