Oil Spill Responder Applications (OSRAp) is a series of modules dedicated to maritime oil spill response operators, for oil spill preparedness activity as well as during an oil spill incident (Application available in french and English: - (1) Unit converter to easily convert different units (distance, volume, speed etc); - (2) Oil slick trajectory: Using wind and current data, the module allows to easily and rapidly estimate the oil slick drifting speed and direction as well a possible final location of the oil slick (considering the geographic coordinates of the spill source and a duration of drift simulation). Drift prediction can be exported in KMZ format and opened on Google earth or any other Geographic Information System (GIS). or report in pdf file is also available. - (3) Oil Quantification. The Module allows to rapidly evaluate a volume of oil spilled based on data derived from aerial surveillance (Percentages of oil coverage for each Bonn Oil Appearance Codes in estimated surfaces). The module allows to estimate volume of chemical dispersant required to treat the oil slick oil slick. A report in pdf file is available - (4) Dispersant Application: The module allows adjusting speed of vessels and dispersant pump flowrate for a proper Dispersant Oil Ratio (DOR). It also calculates the quantity of oil dispersed and dispersant needed for spraying operations with several vessels. *********** Oil Spill Responder Applications (OSRAp) est une série de modules destinés aux opérateurs de la lutte contre les déversements d'hydrocarbures en mer, pour les activités de préparation aux déversements d'hydrocarbures ainsi que lors d'un incident de déversement d'hydrocarbures. L'application existe en français et en anglais - (1) Convertisseur d'unités pour convertir facilement différentes unités (distance, volume, vitesse, etc.) ; - (2) Trajectoire de la nappe d'hydrocarbures : En utilisant les données de vent et de courant, le module permet d'estimer facilement et rapidement la vitesse et la direction de dérive de la nappe d'hydrocarbures ainsi que sa localisation finale possible (en tenant compte des coordonnées géographiques source et d'une durée de simulation). Les prévisions de dérive peuvent être exportées au format KMZ et ouvertes sur Google Earth ou tout autre Système d'Information Géographique (SIG). Un rapport au format PDF est également disponible. - (3) Quantification du pétrole. Le module permet d'évaluer rapidement le volume d'hydrocarbures déversés sur la base des données obtenues lors de la surveillance aérienne (pourcentages de couverture des hydrocarbures pour chaque code d'apparence selon l’accord de Bonn). Le module permet d'estimer le volume de dispersant chimique nécessaire pour traiter la nappe d’hydrocarbures. Un rapport en fichier PDF est disponible - (4) Application du dispersant : Le module permet d'ajuster la vitesse des navires et le débit de la pompe à dispersant pour obtenir un bon rapport entre le dispersant et l'huile (DOR). Il calcule également la quantité d’hydrocarbures dispersé et de dispersant nécessaire pour les opérations d’épandage de dispersion avec plusieurs navires.

Verdict

The call

The clearest difference is in-app purchases: osrap at none against Metal Detector Pro+'s 3. osrap also leads on iOS requirement (13.0 vs 15.0). Metal Detector Pro+'s advantage is device support. On price there is nothing between them.
