  • Environmental Technicians – It’s a Dirty Job

    But someone’s got to do it. Environmental Technicians are unsung heroes at Global. Their job isn’t glamorous. And while they’re not diving to great depths or piloting ROVs, the services our Enviro Techs provide are absolutely vital to Global, to our clients, and to the environment. Along with providing preventive booming and spill response services, our Enviro Techs play a ...

  • Lamor & Arctia study effectiveness of oil spill response applications in ice

    Arctia Karhu Oy’s harbor icebreaker, Ahto, based out of Kemi in northern Finland, is participating in oil spill response research and development in the Gulf of Bothnia, between Ajos and Tornio, during the first week of February, 2016. The ice trials will test and examine the effectiveness of mechanical oil spill response operations in ice and the behavior of oil throughout ...

  • Sea Fair - Breasting Barge Install - Case Study

    Global’s Marine Services Division provided breasting barges and security boom to support to arrival of the US Navy ships that took part in the Sea Fair celebration in Seattle. Sectional barges sections were deployed into the water, yokohama fenders affixed to the barge and the barges were secured to the pier piling to fend the Navy ships from the pier. Once at berth, the ships were ...

  • 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 ...

  • Offshore oil spill clean up case study

    In the event of a major incident occurring offshore, for example a tanker casualty running aground or breaking up for any reason, it is of paramount importance to deploy emergency response to protect and save human life. Once this has been done an assessment of the casualty should be made on whether it is possible to salvage the vessel and its contents and to assess the type and amount of oil ...

  • Issues and challenges with oil toxicity data and implications for their use in decision making: A quantitative review

    Aquatic toxicity considerations are part of the net environmental benefit analysis and approval decision process on the use of dispersants in the event of an offshore oil spill. Substantial information is available on the acute toxicity of physically and chemically dispersed oil to a diverse subset of aquatic species generated under controlled laboratory conditions. However, most information ...

  • 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 ...

  • 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 ...

  • Energy and Environment in the European Union

    Introduction Energy gives personal comfort and mobility to people, and is essential for the generation of industrial, commercial and societal wealth. On the other hand, energy production and consumption (including heat and electricity production, oil refining and final uses in households, services, industry and transport) place considerable pressures on the environment. These pressures include ...

  • Unique sponge system contains water contaminants in storm drains

    Untitled Document SmartSponge technology captures oil and hydrocarbons from stormwater runoff, preventing its discharge into receiving waters. Water quality is being ...

  • 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 ...

  • 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 ...

  • 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 ...
