Options for Deep Sea
Voyages
A. Ballast water exchange
1. |
Introduction:
Near-coastal (including
port and estuarine)
organisms released in
the [deep sea,] and
oceanic organisms released
in coastal waters,
do not generally survive.
Ballast water
exchange in the at deep
sea, such as through
sequentially emptying
and refilling the
ballasted tanks or causing
water to
flow-through ballasted
tanks, can therefore
reduce the probability
of transfers of
harmful aquatic organisms
and pathogens. |
2. |
Safety: When
exchanging ballast at
sea, guidance on safety
aspects of ballast water
exchange as set out
in part B of the this
Appendix shall be
[taken into account][followed].
When
exchanging ballast water
at sea, the ship's
safety shall be of paramount
importance and
the appropriate conditions
set out in .....
shall be strictly observed. |
3. |
[Location: Ships
shall conduct ballast
water exchange in water
500 meters or more in
depth and 200 nautical
miles or more from shore.] |
4. |
Techniques: When
conducting ballast water
exchange, one of the
following techniques
shall be employed:
- |
The sequential method. Where this
method is employed,
all of the
ballast water
should be discharged
until suction
is lost, and stripping
pumps or eductors
should be used if
possible; and
|
- |
The flow-through method. Where
this method is
employed in the deep
sea by pumping
ballast water into the
tank or hold
and allowing the water
to overflow,
at least three times the
tank volume should
be pumped through
the tank. |

Introduction: Near-coastal (including
port and estuarine) organisms
released in the
[deep sea]open ocean
and oceanic organisms

survive. Ballast
water exchange in the
at [deep sea,]
open ocean, such as through
sequentially emptying
and refilling the
ballasted tanks or causing
water to
flow-through ballasted
tanks, can therefore
reduce the probability
of transfers of
harmful aquatic organisms

Location: ships shall conduct
ballast water
exchange in deep water,
in open ocean
and as far as possible
shore,[but not
less than 200 nautical
miles][ and in
water depths of 500
meteres or more]. |
