VSP 2018 Operations Manual

In Port
Before arriving to a port or HARBOR, the seawater supply system
must be shut down and the facility closed for use before the vessel
reaches the 20-kilometer (12-mile) mark or any point of land-based
discharge. The system must remain empty while in port or at
anchor or the flow-through supply must be switched to POTABLE
WATER.

Recirculation
Fill water must be provided only to the compensation tank and not
directly to the BABY-ONLY WATER FACILITY.

TURNOVER Rate
The entire volume of water must pass through all parts of the
system to include filtration, secondary UV DISINFECTION, and
halogenation at least once per half hour.

The filtration, UV DISINFECTION, and HALOGEN and pH
control systems must be operated 24 hours a day. This is required
even when the facilities are not in use. The systems may only be
shut down for required maintenance or cleaning of system
components.

13.8.3.4 Filtration
BABY-ONLY WATER FACILITY water must be filtered.

At least one replacement cartridge or canister-type filter must be available.

Cartridge or canister-type filters must be inspected weekly for cracks,
breaks, damaged components, and accumulation of excessive organic
material.

Granular filters must be backwashed daily. Backwashing must be repeated
until the water viewed through the sight glass or discharge point is clean
flowing.

The granular filters must be opened monthly and examined for channeling,
mounds, or holes in the filter media. Inspection method: Drain the
water from the filter housing and inspect the granular filter for
cracks, mounds, or holes.

A core sample must be examined monthly for accumulation of excessive
organic material. Core sample method:
1. Take a sand sample from the filter core after inspection and
place it in a clear container. A core sample can be taken by
inserting a rigid hollow tube or pipe in to the filter media.
