Pollution from ships

#10 Even Ballast water has to have a log book of its own in Australia Johnny . I came here permanently in 1991 and you could not just deballast water from abroad ad lib. In case of chemical or other pollution into Australian waters. At the time I failed to see why , as one of the terms of chemistry or other sciences , water is not compressible and will spread given time , anywhere there is a space. But the law is the law regardless us not to reason why, but to do and die just like those US Rangers on Omaha Beach 80 years ago. Cheers JS

#8 The great lakes have been toxic for decades.

In the late 1960s, all along the Great Lake shores, collections of junk contributed to a mass of waste being used as landfill. Especially in the shores of Lake Erie, the piles of trash suffocate fish, fill the shorelines with untreated wastes, and slowly contribute to the lake's premature death.

The clean water act did not come into being until 1972.

Even to this day the lakes remain highly toxic.

I’m in Ohio today to discuss how the Bipartisan Infrastructure Law will deliver for the American people. We’re announcing a $1 billion investment through the law to accelerate the restoration and cleanup of the Great Lakes — securing clean water for millions of Americans.

Drinking water!!! even here in the UK in recent weeks advisories have gone out in several ares, not to drink tap water or boil your water before use.

I was on tankers for about five years, used to take the wheel for anything up to eight hours, as blokes preferred cleaning tanks, on every one the sludge was pumped over the stern, and that was only one tanker out of hundreds doing the same.
As for drinking water we have been drinking bottled water for the last ten years only use tap water for tea, coffee or cooking, not so much for pollution but to avoid Floride, which every council puts in the water, the big Aluminum Co's get rid of the waste from production that way,plus make money .

According to professor Journalist, a well known presenter here in Oz of gloom and doom.
The global warming is being caused by the ships of today.

Ships now run on clean fuel, either LPG or with diesel generators which provide the ships with electric power.

Years ago they either burned coal or oil and this saw large black clouds coming from their stacks.
This kept the suns heat to a lower level so the sea did not heat up so much.

This is some of the crap the climate cult followers believe.

#14 what is clean fuel John? yes the fuels they burn now are lower in Sulphur content.
Ships still use HFO and MGO. Newer tonnage are using LNG or Methanol. Hydrogen is coming online.
Most new builds are usually dual fuel but they still have fossil fuel bunkers.

For several years I was on the shuttle service from the Arabian Gulf to the Louisiana offshore oil terminal.
We always went via South Africa. It was as said a shuttle service. There was usually a yellow sulphur plume form the funnels and as ships were usually about 24 hours apart and following more or less the same course. On days when there was no wind you could smell the emissions from ships ahead of you.
I find it hard to believe that there are still those who are in denial about climate change.
Was it Des who said they had -8 degrees in his home town this last week? and winter is only beginning this month.

Not sure about UK but Sulphur was taken out of all diesel here was taken out about 20 years ago.

Pollution now from ships is minimal compared to our time when all rubbish went over the wall.
Now it is all stored and taken ashore at the end of each voyage.

But on occasions a slight oil slick can be seen on the waters, there are some ships that do not abide by all the international regulations.

Yes John, sulphur content has been greatly reduced for years, it is a world wide thing.
Well John feel any guilt about the dishes you may have dumped over the wall during your time with UCL. :p Mind lord only knows what was in the washing up liquids used back in the day.
Think when I first went to sea when pumping ER bilges you could avoid using the oily water seperator by using the GS pump instead of the bilge pump. Golden rule was make sure you went sea to sea when finished pumping bilges to remove any oily residue. Seem to remember the OWS had three levels with testing cocks so you could see the bilge water that was being discharged. When you hit oil you chaged to another bilge.. Think the rules now are maximum oil discharged overboard is not to exceed 30 litres per nautical mile and that is only allowed if the vessel is 12 miles +from nearest land..
I could cringe when I think back to dirty oil tankers , tank cleaning and changing ballast, Best thing ever to happen to oil tankers was to make them double hulled so you were only ever discharging clean ballast. Even that had it's draw backs as discharging your clean ballast loaded say port A and discharging it in port B thousands of miles away. Now tankers are required to carry out a ballast change enroute. Reason is to stop depositing living organisims from Port A to Port B which will help reduce the environmental impact around the Globe.

Yes we had minus 8 last week been on average minus 1 or 2, today it's a nice sunny day but cold wind. the snow boaders are down for the long week end, King or is it Queens birthdaybeen so many in my life I forget LOL.

The ban or check on ballast was brought in I think over the Starfish epidemic in the Barrier Reef, came down not only on ships bottoms but in the ballast water.

Des, you should come down here to Mexico, south of the border, we are struggling with low temperatures of about 12 to 15 degrees.

Whatcha doing down there John ? Hope you visit the site of the battle of the Alamo and bring back a replica of Davy Crocketts hat , bringing one back for Des to keep his head warm as is complaining of the cold. Cheers and keep off the Tequilla . JS
