MARITIME – POLLUTION PREVENTION & ENVIRONMENTAL CALCULATOR
Marpol Annex I Discharge
A precise tool.
What is the Marpol Annex I Discharge & How does it work?
MARPOL Annex I, also known as the International Convention for the Prevention of Pollution from Ships, sets strict limits on the discharge of oil and oily mixtures into the sea.
The discharge criteria are based on ship size, the volume of oil, distance from the nearest land, oil concentration, and whether the vessel is operating in a designated special area.
Allowed = \begin{cases}1 & \text{if criteria met}\\ 0 & \text{otherwise}\end{cases}
Allowed = 1 (discharge permitted) or 0 (not permitted)
By entering the vessel’s operational data, the calculator evaluates each condition and instantly informs the crew whether a discharge complies with MARPOL regulations.

Frequently Asked Questions
What are the key factors considered in determining if oil can be discharged?
The key factors include ship size, volume of oil, distance from land, oil concentration, and whether the vessel is in a special area.
How does the calculator determine if discharge is allowed?
The calculator checks if all criteria set by MARPOL Annex I are met. If they are, discharge is permitted; otherwise, it is not.
Can a ship always discharge oil near land?
No, the distance from the nearest land and oil concentration must meet specific limits to allow discharge.
What happens if a ship operates in a designated special area?
In a special area, additional restrictions apply, making it harder to meet the discharge criteria.
Is there a limit on the volume of oil that can be discharged?
Yes, the volume of oil and its concentration must comply with MARPOL Annex I regulations to permit discharge.
How does ship size affect oil discharge permissions?
Larger ships may have stricter requirements regarding oil discharge to prevent pollution.
What is the purpose of MARPOL Annex I?
MARPOL Annex I aims to reduce pollution from oil and oily mixtures discharged into the sea by setting strict limits on discharge criteria.
