Cruise Ship Hygiene Management: Part II
In a previous blog, we took a look at some of the hygiene processes followed aboard the mega-ships that tour our oceans. Today we’ll be taking a look at the legislation behind it all. The following content is based on the Guide to Ship Sanitation by the NCBI (National Center for Biotechnology Information), which forms a part of the United States National Library of Medicine, a branch of the National Institutes of Health.
National & Local Authorities Manage Discharge Laws
Cruise ship waste disposal is managed according to the wishes of national and local authorities at each port of call. In general, and for obvious reasons, ships are not permitted to discharge sewage or any other liquid containing contaminating or toxic wastes within an area from which a water supply is drawn or in any area restricted for the discharge of wastes. Overboard discharge is also subject to the rules and regulations of individual harbours, ports and coastal waters.
Barges Or Shore Connections Are Normally Provided
Certain countries provide special barges for receipt of waste. Others provide shore connections that allow for input into the sewer system. Certain shore service providers may provide their own hose for these purposes, but in other cases, ships could be expected to provide their own durable, impervious hose with connections that are large enough to facilitate rapid waste discharge.
On-Board Sewage Treatment Provides a Fall-Back
In certain cases discharge may be completely prohibited near water supply intakes or in bodies of water in which measures have been taken to prevent and control pollution. In cases like these, ships should have sufficient retention tanks and sewage-treatment equipment on board to tide them over until their next port of call.
Grease Traps, Food Waste & Pharmaceutical Waste Are Also Under Scrutiny
There are separate rules and regulations that pertain to the management of waste generated by grease traps, food waste in general, as well as medical and pharmaceutical waste generated at onboard spas etc.
With this kind of legislation in place, the hope is that our oceans will be safeguarded against damaging waste disposal. Did you find this interesting? Good! We’ll be sharing more interesting perspectives on shipping and ocean-faring right here on the blog in the coming weeks and months, so keep an eye out.
