Where potable water supplies are disrupted by natural disasters such as hurricanes and tsunamis, SEADOV units can be de-ployed quickly to provide water until regular supplies are restored, then moved to other areas of need. El Niňo conditions in the Pacific produce droughts on the east coast of Australia and floods on the west coasts of the Americas, and these alternate with La Niňa conditions which produce the reverse - E.G. floods on the east coast of Australia and droughts on the west coasts of the Americas. SEADOV units can move backwards and forwards across the Pacific to drought areas as required. SEADOV will also be capable of delivering a hybrid supply alternating as required between water and power delivery.
SEADOV can supply enough water for small scale intensive irrigated horticulture which may make the difference between star-vation and wellbeing in some areas. Increasing the annual crop yield can also be the difference between successful farming outcomes and bank-ruptcy. SEADOV can maximise annual yields due to reliable water supply year round, begging the question ‘what price water’ ?
In many coastal cities of the world during drought periods, restrictions are enforced by policing water usage and fining citizens who abuse. During these periods brown and devastated landscapes soon proliferate. With SEADOV as a backup system to augment dwindling dam water storage supplies, water restriction events can be substantially deferred and even eliminated, allowing citizens to freely use water in any way they choose, including garden hosing etc, but with the option of selling additional water at a premium price to those who choose to pay for its un-restricted use. This premium income collected by authorities can be argued to be a realistic way to justify the deployment of SEADOV’s. When and if dam water supplies become chronically depleted, restrictions can again be imposed but delayed until absolutely necessary and with the comfort of knowing that some water supply will always be available via SEADOV. Deploying SEADOV vessel(s) can therefore be utilized as an effective back up to diminishing dam supplies. Once the emergency has past, citizens can resume unrestricted water access, but having the certainty of the backup SEADOV supply during drought periods. Importantly SEADOV deployments can also defer the need to expand expensive dam capacity and construction which in many locations is seen a destructive use of otherwise productive land.
Small islands often lack catchment and storage for potable water and suffer water shortages in dry seasons. Depending on local condition SEADOV can meet be the solution to meet the shortfall as the cost of desalinating water using diesel or other fossil fuels trans-ported from a distant mainland can be at a crippling and increasing cost. A Hybrid supply alternating between power and water will likely also prove useful in Islands relying on shipped in diesel supplies.
Mining companies and heavy industry throughout the world often exist in remote coastal regions often requiring large volumes of potable water for process and general use. Depending on local prevailing sea and wind conditions SEADOV may prove very cost effective to deploy.
SEADOV holds the potential in many circumstances to offer a hybrid supply of power and water. Mining sites, emergency light and power in devastated areas The cost effectiveness of doing so can only be correctly assessed subsequent to analysing best available nearby sites.
