Systems of water and wastewater treatment for offshore and coastal facilities under the conditions of Arctic climate
Summary
The aspects of designing water supply and wastewater treatment systems for offshore Arctic facilities – floating drilling units, platforms and terminals are considered. Owing to the special conditions of operating floating drilling units in Arctic marine during long ice seasons a number of additional requirements to the water treatment systems shall be taken into consideration. Among them is reduction on the use of tankers-water carriers and of the fresh water reserve at the offshore facilities inter alia by abandoning the discharge of grey wastewater after proper treatment into the sea. Designing floating facilities of special purpose with the use of advanced small-scale and efficient systems of water purification and wastewater treatment – life-support vessels that is a separate trend in shipbuilding has been suggested and justified. Life-support vessels can be used for water transportation and waste disposal or as seasonal water and wastewater treatment systems for different purposes including emergency conditions.
