  • Stochastic models of oil spill processes

    This paper models the occurrence of an environmental accident as a stochastic event. In particular, the situation of an oil spill is explored. Characteristics of the ship operator, and the different types of the ship's operating environment determine a stochastic process governing the time patterns and size of spills. It is shown that both the time distribution of different types of oil spill and ...

  • Oil Spill Technologies Heat Up

    The highly successful, widespread deployment of PyroBoom® fireboom for controlled burning in the Gulf represented a crowning achievement in a development journey spanning more than 30 years. The concept of burning spilled or leaked oil on the sea’s surface has been known for many years, offering an extremely effective way of reducing the spill by as much as 90 percent with minimal ...

  • An empirically tractable model of optimal oil spills prevention in Russian sea harbours

    Based on previous theoretical work by Gottinger (1997, 1998), we propose a simple model of optimal monitoring of oil-related activities in harbour areas that is suitable for empirical estimation within the Russian— Ukrainian context, in spite of the poor availability of data in these countries. Specifically, the model indicates how to best allocate at the steady state a given monitoring budget ...

  • Econometric modelling, estimation and policy analysis of oil spill processes

    This paper explores approaches to model specification suitable for empirical investigation of a stochastic oil spill model. We focus on the effects of economic incentive measures on the frequency of oil spills, spill size, and volume of oil spilled. We look into the relationships between parameters that describe the spill generation process and the enforcement effort, using data for the Black and ...

  • Groundwater Remediation System Cleans Up Oil Spill

    A customer in TX was recently in some hot water with the local municipal water department. Due to excessive rains near the coast of Texas, the water levels have been higher than usual. The company fills storage tanks with diesel at its facility. However one day the tanks were overfilled and instead of going into the ground, they diesel dispersed out via the high rain water and into the local ...

  • Effects of chemical dispersant and seasonal conditions on the fate of spilled oil – modelling of a hypothetical spill near Saint John, NB

    The proposed Energy East pipeline project has raised concerns about potential oil spills in Saint John, New Brunswick. While environmental conditions could pose challenges for using mechanical recovery methods if a spill occurs, chemical dispersant could be an alternative. However, the application of chemical dispersant in shallow water and costal zones remains an issue of debate. Furthermore, ...

  • Power plants use oil skimmers to prevent contamination from spills

    Most hydroelectric plants designed in the 1960s were built with a station drainage sump that collects all drainage from the plant. As designed, float switches activate sump pumps that discharge liquids directly into the tailrace. The system cannot distinguish between types of liquids, so in the event of an oil leak, oil in the sump could be released into the tailrace. Modern ...

  • New approach makes faster and efficient work of oil spills

    A comprehensive new study of oil’s behaviour in various sea conditions has resulted in significant advances in oil spill recovery using boom-style systems. Put into practice in DESMI ‘s Speed-Sweep Oil Spill Response (OSR) solution, the new approach speeds up oil recovery, increases encounter rates, covers a wider area in a shorter time and provides new flexibility in the choice of ...

  • Quantifying population‐level risks using an individual‐based model: Sea otters, Harlequin Ducks, and the Exxon Valdez oil spill

    Ecological risk assessments need to advance beyond evaluating risks to individuals that are largely based on toxicity studies conducted on a few species under laboratory conditions, to assessing population‐level risks to the environment, including considerations of variability and uncertainty. Two individual‐based models (IBMs), recently developed to assess current risks to sea otters and ...

  • A dynamic model of optimal reduction of marine oil pollution

    This paper proposes a system of dynamic models to describe the interactive behaviour of different agents (polluters, inspectors, and a principal pollution control agency) involved in the processes of marine oil pollution and of its prevention and purification, under some realistic assumptions. In particular, short- and long-term economic responses of polluters to monitoring efforts, as well as ...

  • Case study - Public-private partnership successfully tests leakwise early oil spill detection sensor in the tidal Delaware river

    Background In the summer of 2011, the Delaware River Basin Commission (DRBC) and the U.S. Geological Survey (USGS) collaborated with GE Analytical Instruments on a unique test deployment of an oil sheen sensor in the tidal Delaware River. The idea for the test deployment arose during meetings of the Delaware River and Bay Oil Spill Advisory Committee, which includes organizations and ...

  • Oil in frac water testing

    The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well. Whether the water is going to be taken off site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the wa-ter. Waiting for remote laboratory results can take several days to a week. The InfraCal TOG/TPH ...

  • Impact–based cost–benefit analysis model for management of crude oil contaminated agricultural soil

    Evaluating the compensation payable to farmers whose farms/farmlands have been rendered unproductive due to oil spill requires adequate scientific research and improved decision–making. This work proposes a bacterial–based mathematical framework as a decision–support system for evaluating crude oil spill impact on agricultural soil. The rate of 'in situ' biodegradation of the crude oil predicts ...

  • Enhancing the hydrophobicity of mangrove bark by esterification for oil adsorption

    Oil spills generally cause worldwide concern due to their detrimental effects on the environment and the economy. An assortment of commercial systems has been developed to control these spills, including the use of agricultural wastes as sorbents. This work deals with raw and modified mangrove barks (Rhizophora apiculata), an industrial lignocellulosic waste, as a low cost adsorbent for ...

  • Study of the dispersion/settling of oil–mineral–aggregates using particle tracking model and assessment of their potential risks

    A random walk particle tracking model was used to simulate the motions of oil–mineral–aggregates (OMAs) under hydrodynamic conditions involving wave–induced velocities, random velocities due to turbulence, and the settling velocity due to gravity. Wave–induced and settling velocities for OMAs determined from the application of Stokes's theory and empirical equations derived from experimental data ...
