Disinfection and conservation of water with silver ions. The Electro-Katadyn system is adding
silver ions to the water by an electrolytic process. The Electro-Katadyn EK-2/24 is a silver
ionizing unit for water volumes up to 16 m3/h with a silver dose of < 50 ppb. Preserves natural
taste of water. Long conservation of water. Requires smallest amounts of silver (no health
hazard).

Discharge of residues of category X

6.1 Subject to the provision of paragraph 1, the following provisions shall apply:

.1 A tank from which a substance in category X has been unloaded shall be

prewashed before the ship leaves the port of unloading. The resulting residues
shall be discharged to a reception facility until the concentration of the substance
in the effluent to such facility, as indicated by analyses of samples of the effluent
taken by the surveyor, is at or below 0.1% by weight. When the required
concentration level has been achieved, remaining tank washings shall continue
to be discharged to the reception facility until the tank is empty. Appropriate
entries of these operations shall be made in the Cargo Record Book and
endorsed by the surveyor referred to in regulation 16.1.
.2 Any water subsequently introduced into the tank may be discharged into the sea
in accordance with the discharge standards in regulation 13.2.
 .3 Where the Government of the receiving party is satisfied that it is impracticable
to measure the concentration of the substance in the effluent without causing
undue delay to the ship, that Party may accept an alternative procedure as being
equivalent to obtain the required concentration in regulation 13.6.1.1 provided
that:
.3.1 the tank is prewashed in accordance with a procedure approved by the
Administration in compliance with appendix 6 of this Annex; and
.3.2 appropriate entries shall be made in the Cargo Record
Book and endorsed by the surveyor referred to in
regulation 16.1.

7 Discharge of residues of category Y and Z

7.1 Subject to the provision of paragraph 1, the following provisions shall apply:

.1 With respect to the residue discharge procedures for substances in category Y or

Z, the discharge standards in regulation 13.2 shall apply.
.2 If the unloading of a substance of category Y or Z is not carried out in
accordance with the Manual, a prewash shall be carried out before the ship
leaves the port of unloading, unless alternative measures are taken to the
satisfaction of the surveyor referred to in regulation 16.1 of this Annex to
remove the cargo residues from the ship to quantities specified in this Annex.
The resulting tank washings of the prewash shall be discharged to a reception
facility at the port of unloading or another port with a suitable reception facility
provided that it has been confirmed in writing that a reception facility at that port
is available and is adequate for such a purpose.
.3 For high-viscosity or solidifying substances in category Y, the following shall
apply:
.3.1 a prewash procedure as specified in appendix 6 shall be applied;
.3.2 the residue/water mixture generated during the prewash shall be
discharged to a reception facility until the tank is empty; and
.3.3 any water subsequently introduced into the tank may be discharged into
the sea in accordance with the discharge standards in regulation 13.2.

7.2 Operational requirements for ballasting and deballasting

7.2.1 After unloading, and, if required, after a prewash, a cargo tank may be ballasted.
Procedures for the discharge of such ballast are set out in regulation 13.2.

7.2.2 Ballast introduced into a cargo tank which has been washed to such an extent that the
ballast contains less than 1 ppm of the substance previously carried may be discharged into the
sea without regard to the discharge rate, ship’s speed and discharge outlet location, provided that
the ship is not less than 12 nautical miles from the nearest land and in water that is not less than
25 metres deep. The required degree of cleanliness has been achieved when a prewash as
specified in appendix 6 has been carried out and the tank has been subsequently washed with a
complete cycle of the cleaning machine for ships built before 1 July 1994 or with a water
quantity not less than that calculated with k = 1.0.

7.2.3 The discharge into the sea of clean or segregated ballast shall not be subject to the
requirements of this Annex.

8 Discharges in the Antarctic Area

8.1 Antarctic Area means the sea area south of latitude 60° S.

8.2 In the Antarctic Area any discharge into the sea of noxious liquid substances or mixtures
containing such substances is prohibited.

Q-PV ALARMS OG IG SYSTEM

 For inert tanks the pressure in the tank should never be

permitted to fall below zero and so the pressure sensors within
the IG system required by the Inert Gas Code and SOLAS
 should be set to alarm at positive 200 mmWg (LOW) and 100
mmWG (LOW -LOW). Should the low pressure alarms sound or
there be a failure of the IG system, discharging operations
must be suspended immediately.

With regards to the individual tank pressure sensors, these

should be set to positive 50 mmWg in order to give warning in
the event that the main IG alarms have failed to suspend cargo
discharging operations. This equally applies where nitrogen
has been taken from shore to provide padding .

PV VALVE SETTING

Pressure vacuum valve or pv valve in the ventilation system will prevent either over or under
pressure. They are set usually so that tank pressure of about 0.14 bar will lift the main valve
(The smaller valve will lift along with it) and release excess pressure

PV BREAKER SETTING

What is pv breaker lift setting ? PV breaker operates at 1600 to 1800 mm of Water

Column and at a vacuum of -400 mm of Water Column.

Marpol Annex 1, Regulation 30.4.2 requires every oil tanker delievered

after 1 June 1982, required to be provided with segregated ballast tanks
or fitted with a crude oil washing system, shall comply with the following
requirements
 it shall be equipped with oil piping so designed and installed that oil
retention in the lines is minimized; and

 means shall be provided to drain all the cargo pumps and all oil lines at
the completion of cargo discharge, where necessary by connection to
the stripping device. The line and pump draining shall be capable of
being discharged both ashore and to a cargo tank or a slop tank. For
discharge ashore, a special small diameter line shall be provided
and shall be connected outboard of the ship's manifold valves
The small diameter line mentioned here is also called Marpol Line.
