ships bogs

[Alrob]

As a tangent to HLB's post about his Bog, I was asked recently about what happens to cruise liners waste. I couldn't answer but I presume they have treatment plants!

Can anyone answer this for me ?

I hope every ones finished eating /forums/images/graemlins/laugh.gif

From my experience some years ago, Fred Olsen's "Blackwatch" and "Blenheim" had treatment plants. So did Jebsen's smaller bulk carriers. On a trip up the St Lawrence seaway we were allowed to use the ship's heads because a treatment plant was fitted but, on another ship without one, a couple of fragrant Portaloos had to be loaded on board. /forums/images/graemlins/frown.gif

All the cargo ships I served on had treatment plants. It was always said you could drink the water that came out, but never saw actual proof of that!

As with all technology time causes changes.

In the early sixties only passenger vessels were fitted with sewage treatment plant, as most of the ships I was serving on then were built in the forties/fifties when there were other things on designers minds (like replacing wartime losses) so no sewage treatment, voltage 220DC only, no A/C or sesalination plant and no Formica either.

I understand that vessels now have to have treatment plant as standard.

********************************************
All ships now have to have a comprehensive waste management program and not even the zip strip of a fag packet should be thrown over the side.

These passenger ships try to have a zero impact on the environment and so have both black (BOG) waste and Grey water water purification and storeage systems. Moreover all solid waste is stored and sorted into about five catagories for putting ashore.

SHips are also not supposed to discharge ballast water in one port that was taken on board in another as this water could carry all sorts of organisms. If it is anticipated that water will be discharged in another port then those tanks have to be flushed out and refilled in mid ocean.

This environmental thing even extends to impact on the environment from exhaust and not only to the ships have to comply with exhaust limits but if you check out some sites on the subject you will for instance discover that where a great number of cruise ships go to a specific location then they actually ration duration and number of ships allowed at that location per day....Just because your itinary says you will see Glacier Bay on a certain day may be no guarantee...you might be diverted to look at polar bears if the limit for exhaust pollution that day is already reached!!!!!

I once knew a Chief Engineer who had superintended a new build and he claimed that the engineer who installed the plant on his ship drank a glass of water from the system after commissioning and testing it. I don't know what the testing consisted of; perhaps the commssioning engineer took the crew out for a curry on expenses the night before /forums/images/graemlins/frown.gif

as I understand it .....

it is compressed and left to solidify, then dumped over the side in Southampton docks

It is then taken upto the local football ground where it is put on display each week

Yep quite true.

Little Japanese commissioning eningeer downed a glass.

Sewage plant was the License copy of Hamworthy aerobolic three chamber unit if my memory is good.

When you think of the number of times Thames water is recyled through th esupply and waste plants by the time it gets to the sea not so astounding after all.

Re: ships bogs - ex seafarer tales

Seems like we have quite a few ex MN around - ah 220V open face plate starters, scotch boilers and weirs pumps, those were the days.

Shame the UK has not kept at least one cargo vessel, like the Germans have in Hamburg - a Doxford SD14 perhaps - to remind future generations of the fact we once had biggest fleet and shipyards in the world. I support the Sheildhall but its not a deepsea vessel.
