Marine Oil Spill

One of the worst nightmares for the maritime industry is open sea oil spill. Disasters such as the MV ‘Exxon Valdez’ and ‘Sea Empress’ are good cases on the impact both in terms of financial and environment. Literally hundreds of millions if not billions are spent on each oil spill disasters.

up procedures for oil spills would involve many equipment and expertise such as oil booms, recovery crafts and dispersant chemicals. In the USA, oil spill contingency planning now include dispersant use as a response option under certain conditions. In other parts of the world, such as in Asia, Great Britain and Europe, dispersants have become the main response technique for oil spills. Dispersant use was considered to be a major factor in reducing shoreline oiling and biological impacts at the MV ‘Sea Empress’ oil spill in Wales in 1996.



Use of Dispersant in Marine Oil Spill

The environmental impact on the usage of dispersants in oil spills have been largely studied by many international agencies as some dispersants affects the marine ecology more than others.

The decision to use dispersants involves balancing the potential advantages of dispersant use--removing oil from the water surface and avoiding some shoreline impacts with the potential disadvantages, such as impacts to plankton or other water column organisms. Toxicity is the primary concern. To date international marine conservation and environmental agencies advocate only the use of dispersants that are very low in toxicity. Typically the dispersants are evaluated using toxicological test apparatus as in the Diagram 1 below to evaluate the impact on the marine ecology system.

Miyabi Dispersants

Developed under strict Japanese environmental regulations, Miyabi range of dispersants are OEM for many brands. Our Miyabi Oil Spill AidTM (MOSA), Miyabi Oil Spill ControlTM (MOSC), Miyabi Tank CleanerTM (MiTaC), MiDeg (Miyabi Degreaser) are few of the dispersants in the commercial market that meet such criteria.

Our dispersants are water based and hydrocarbon free, and extremely low in toxicity. We also develop an advance biodegradable range for sensitive ecological concerns. Our dispersants are;

  • It is highly effective at emulsifying crude oils, fuel oils and
    water in oil emulsions.
  • Do not adhere to rock walls and coastal walls
  • Caused dispersed-emulsified oils to scatter, float on the
    water and do not settle to the bottom of the sea.

Does Miyabi Dispersants Work?

In layman terms, they work much like the detergent use in cleaning grease and oil from cooking utensils (but our dispersants are very much less toxic and more complex). They contain molecules with a water-compatible ("hydrophilic") end and an oil-compatible ("lipophilic") end. These molecules attach to the oil, reducing the interfacial tension between oil and water, breaking up the oil slick. Refer to Diagram 2 below.

Diagram 2 – How dispersant works.
Upon application with Miyabi dispersants, oil slick beaks down into oil droplets and globules. This enables the suction pumps to ‘skim’ off the oil droplet and globules from the surface of the sea with ease and greater efficiency as compared to large sticky mass of oil. Furthermore the break down to oil mass into oil droplets and globules increases the surface area of the emulsified oil and therefore increasing the oxidation and ultraviolet radiation of the sun which aid in the degradation of the oil. Eventually these emulsified oil droplet and globules are degraded into naturally occurring substances.

Researches by international environmental agencies on dispersants had shown dispersed oil degrades more quickly than oil that has not been dispersed. Diagram 3 illustrates how the oil may be processed in the marine ecological system. Initially, the droplets of oil and dispersant are swarmed by bacteria which begin to degrade them. Then protozoans and nematodes (small worms) join the colonies. Eventually, the oil may be further broken down and incorporated into the food web.
