I have a question: Does this also apply to Singapore waters?

[cat60y]

Hello sailermoon,

“All ships flagged under countries that are signatories to MARPOL are subject to its requirements, regardless of where they sail and member nations are responsible for vessels registered on their national ship registry.”

https://en.m.wikipedia.org/wiki/MARPOL_73/78

Singapore as a global shipping hub is one of the signatory.

[Shipmare]

But how much exactly is 15ppm?

“PPM = parts per million

PPM is a term used in chemistry to denote a very, very low concentration of a solution. One gram in 1000 ml is 1000 ppm and one thousandth of a gram (0.001g) in 1000 ml is one ppm. One thousanth of a gram is one milligram and 1000 ml is one liter, so that 1 ppm = 1 mg per liter = mg/Liter.”

[Shipmare]

Another Question regarding Marpol Annex 1,

Special Areas; What is the differences in regulations between discharging of oil in machinery spaces in special area and non special area?

In Both special and non special area, since these critierias are to be made, are all similar
1) Ship must be enroute
2) Must pass through Oily water separator meeting requirement of regulation 14,
3) Must not exceed 15 ppm
4) Must not mix with cargo oil residue.

The Catch is, only in Antartic area ( which is a also special area) that any discharge of oil is prohibited. Kindly correct if im wrong.

And so why are the other special areas so call name special areas in annex 1 ?
