Question 4

What are Special Areas and what are the rules in them?

Answer 4

Special Areas: Sea areas where because of oceanographical and ecological reasons, there are special mandatory requirements in applying MARPOL. Each annex stipulates the requirements for special ares;
Generally no discharges allowed.

Discharge of Sewage in Baltic Sea only through Approved Treatment Plant.

Question 5

Then when refilled with water, that water may be discharged at sea given:

• 7 Knots (or 4 knots if being towed/not self propelled)
• Discharge below waterline
• > 12NM
• Depth >25m

Cat X must be prewashed to 0.1% Concentration.
