  • Realisticstable Water-In-Oil Emulsions at Ohmsett

    ABSTRACT This paper discusses the first two phases of a multiphase study to create predictable stable water-in-oil (W/O) emulsions at Ohmsett including a lab study and a large tank-scale study. The first stage of the study refined the process of creating, characterizing, and testing small batches of W/O emulsions under controlled and reproducible conditions in the laboratory to determine if ...

  • DESMI Lifts Green Ship Business Case

    New rules call for fresh approach It’s hardly news that the shipping industry is mobilising to meet the demands of wave after wave of new environmental regulations. From the IMO’s ballast water management legislation to EEDI (the Energy Efficiency Design Index for new ships) and SEEMP (Ship Energy Efficiency Management Plan), shipowners need to be ready to drastically cut ...

  • 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 ...

  • OSE II economic comparison to dispersants and mechanical Clean ups

    INTRODUCTION   Oil Spill Eater II is the name of a non-toxic product which provides the means for moving oil spill response out of its 19th Century methodology into the realm of advanced technological 21st Century breakthroughs for addressing and remediating 100% of any spill in any environment. In comparison, current response methods employed by three major oil companies - BP, Exxon ...

  • Rational application of chemicals in response to oil spills may reduce environmental damage

    Oil spills, for example those due to tanker collisions and groundings or platform accidents, can have huge adverse impacts on marine systems. The impact of an oil spill at sea depends on a number of factors, such as spill volume, type of oil spilled, weather conditions, and proximity to environmentally, economically, or socially sensitive areas. Oil spilled at sea threatens marine organisms, ...

  • Trans-boundary marine oil pollution and its international legal aspects

    Marine pollution control is a sensitive topic, which has gained importance recently due to crude oil spills which in turn has led to many recent international legal developments. This paper examines the effectiveness of international marine laws in imputing liability and calculating damages where more than one nation is affected. The main international agreements covering the international marine ...

  • Desorption kinetics of naphthalene from sediment particles: batch and stepwise desorption approach

    We investigated three major parameters in simulating desorption behaviours: the pre-contamination period, dilution by clean water mass (dilution ratio) and the length of the time interval between dilutions, in both batch and stepwise desorption experiments using particles pre-contaminated with a polycyclic aromatic hydrocarbon, naphthalene (NAPH). We found that the dilution ratio plays a major ...

  • Photooxidation of crude petroleum maltenic fraction in natural simulated conditions and structural elucidation of photoproducts

    Significant amounts of petroleum enter the marine environment from different sources such as; transportation, natural oil seeps, and oil spills each year (Etkin, 1998). It is estimated that 3.2 million tons of petroleum enters the world oceans each year (Heller, 1993). Most crude oils spilled at sea spread rapidly to form slicks with greatly increased surface area (Nicodem, 1998). Oil entering ...

  • 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 ...

  • 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 ...

  • Empirical data and optimal monitoring policies: the case of four Russian sea harbours

    In this paper, we describe the present state of empirical information about oil spills and oil monitoring activities in Russian harbours. We explain how we gathered, organised, and estimated the data needed to run the monitoring efforts optimisation model of Deissenberg et al. (2001). We present, analyse, and discuss the results of the optimisations carried out with this model on the basis of the ...
