4.1.1 The 15 ppm Bilge Separator should be strongly
constructed and suitable for shipboard use, bearing in mind its intended
location on the ship.
4.1.2 It should, if intended to be fitted in locations
where flammable atmospheres may be present, comply with the relevant
safety regulations for such spaces. Any electrical equipment which
is part of the 15 ppm Bilge Separator should be based in a non-hazardous
area, or should be certified by the Administration as safe for use
in a hazardous area. Any moving parts which are fitted in hazardous
areas should be arranged so as to avoid the formation of static electricity.
4.1.3 The 15 ppm Bilge Separator should be so
designed that it functions automatically. However, fail-safe arrangements
to avoid any discharge in case of malfunction should be provided.
4.1.4 Changing the feed to the 15 ppm Bilge Separator
from bilge water to oil, bilge water to emulsified bilge water, or
from oil and/or water to air should not result in the discharge overboard
of any mixture containing more than 15 ppm of oil.
4.1.5 The system should require the minimum of
attention to bring it into operation. In the case of equipment used
for engine room bilges, there should be no need for any adjustment
to valves and other equipment to bring the system into operation.
The equipment should be capable of operating for at least 24 hours
of normal duty without attention.
4.1.6 All working parts of the 15 ppm Bilge Separator
which are liable to wear or to damage should be easily accessible
for maintenance.
