  • Removal of Particulate Matter (PM) and NOx from marine exhaust gas by combining electrostatic water-spraying scrubber and emulsion oil

    In this study, experiments were performed with combination using emulsion oil and an electrostatic water spraying scrubber to evaluate effectiveness for simultaneous removal of NOx and Particulate Matter (PM) emissions in marine exhaust gas. The effects of several parameters, such corona power, gas flow rate, on the contaminant removals have been investigated intensively. Total PM removal ...

  • Case study - Engine cell exhaust: RTO

    Problem A Mid-western outboard engine manufacturer bought a three year-old plant for the production of its marine engines. When finished the engines are removed from the assembly line and run for quality control. The 25,000 SCFM of exhaust from testing contains volatile organic compounds (VOCs) that require regulatory compliance. Also, within this exhaust is a great deal of water vapor ...

  • Trelleborg Harbour Marine helps moor vessels safely at LNG terminals

    Trelleborg Harbour Marine helps moor vessels safely at LNG terminalsSafety is the priority at LNG terminals, which are growing in number inline with an increased demand for the fuel. Like many fuels, LNG is potentially hazardous and to help reduce the possibility of an incident during berthing or when a vessel is alongside a jetty, integrated mooring systems are becoming standard specification. ...


  • Protection the Marine Environment from Land-Based Sources of Pollution Towards Effective International Cooperation

    The most significant source of marine pollution is from land-based sources, with estimates indicating that it comprises around 80 per cent of all marine pollution. It is an issue of utmost concern. Dr Hassan provides an insight into the technical and legal issues surrounding land-based sources of pollution, and argues for a new international convention that will enhance cooperation, contribute to ...


  • More to Scrubber Pumps than Meets the Eye

    One component, in particular, needs to be carefully selected to ensure safe and efficient sulphur removal. The time is now Shipowners are having to move fast to change fuel type to distillate fuel or LNG, or to install the exhaust gas cleaning systems (EGC systems) known as scrubbers. They’re reacting to new sulphur emission legislation set to come into force in designated ...

  • Auto mechanics find new way to save the environment and money

    Some mechanics have reported a 50% savings in cleaning time by turning to an ultrasonic parts cleaning machine while taking advantage of an ecologically safe alternative to manual cleaning with toxic chemicals. With today's industrial sized ultrasonic cleaners, the speed of ultrasonic cleaning to remove soils is combined with the capacity to clean multiple parts at once. Let's take a look at some ...

  • M/S Mount Washington repower project case study

    In October of 2009, Winnipesaukee Flagship Corporation undertook a project to repower the excursion vesselMt. Washington, with funding from EPA 2009 DERA.  The old engines in the Mt. Washington were two 1946 Enterprise DMG-18s, each producing 615 HP.  The Enterprise engines were pre-regulation EPA Tier 0 engines, and emitted much ...

  • The 80-20 inversion: how we waste time and money without automated systems

    Tracking and analyzing near-misses and at-risk behaviours should be central to any preventive health safety management system. In 2003 ConocoPhillips Marine conducted a study that indicated that for every workplace fatality, there were at least 300,000 at-risk behaviours – basically, activities inconsistent with health and safety rules – and about 3,000 near misses. This applies ...

  • Common Treatment Technologies for Nonhalogenated VOCs in Soil, Sediment and Sludge

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

  • Seeding the oceans may not stop climate change

    Geo-engineering against climate change – Seeding the oceans with iron may not address carbon emissions Numerous geo-engineering schemes have been suggested as possible ways to reduce levels of the greenhouse gas carbon dioxide in the atmosphere and so reduce the risk of global warming and climate change. One such technology involves dispersing large quantities of iron salts in the oceans to ...

  • Can a gas engine use diesel fuel with less pollution?

    Anyone concerned with rising oil prices and pollution from fossil fuel might like to know about a new technology, which addresses both problems. Its application will put an end to the days of sooty smoke seen from accelerating diesel trucks and buses. The ...


  • Influence of Coastal Economic Valuations in the Caribbean: Enabling Conditions and Lessons Learned

    Across the Caribbean, national economies are heavily dependent on coastal ecosystem services. Coral reefs, mangroves, and other coastal ecosystems provide fish habitat, attract tourists, and protect shorelines from storm damage. However, coastal habitats continue to degrade due to local and global pressures. For example, more than 75 percent of the Caribbean’s coral reefs are currently ...

  • Cobalt and its compounds

    Abstract Cobalt is a compound that occurs in nature. It occurs in many different chemical forms. Pure cobalt is a steel-gray, shiny, hard metal. Cobalt used in industry is imported or obtained by recycling scrap metal that contains cobalt. It is used to make alloys (mixtures of metals), colored pigments, and as a drier for paint and porcelain enamel used on steel bathroom fixtures, large ...

  • Coastal Capital: Ecosystem Valuation for Decision Making in the Caribbean

    Executive Summary Tropical coastal ecosystems—including coral reefs, mangroves, beaches, and seagrasses—provide a range of valuable goods and services to people and economies across the Caribbean. These ecosystems contribute to tourism, fisheries, shoreline protection, and more. However, despite their importance, coastal ecosystems are under threat from numerous human ...

  • 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 ...

  • Gas Safety in Confined Spaces

    Introduction An offshore worker ensures a vessel is safe to enter; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face common dangers, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited. A confined space ...

  • A civilizational tipping point

    In recent years there has been a growing concern over thresholds or tipping points in nature. For example, scientists worry about when the shrinking population of an endangered species will fall to a point from which it cannot recover. Marine biologists are concerned about the point where overfishing will trigger the collapse of a fishery. We know there were social tipping points in earlier ...
