Worst Water Weeds #6: Water Hyacinth
Water hyacinth (Eichhornia crassipes) is a floating plant that can grow in all types of fresh-water habitats. Its height above the water can vary from a few inches to as high as three feet. It has broad, glossy, leathery oval-shaped leaves and produces a deceptively pretty lavender or pinkish flower. The stalks are long, spongy and bulbous, and the feathery root masses underwater are purple-black ...

Get Ready for Spring Water Weeds!
Much of the country is deep into the freezing temperatures and snowfalls of winter, but it’s never too early to start thinking about how you’re going to get an edge when spring water weeds emerge in full force. It can take you by surprise – especially if you didn’t take some key winter water protection steps before the cold weather set in. But have no fear, Weedoo is ...

Wintertime Water Ecosystems: Spring into Action Now to Beat Water Weeds!
On February 2 in the small town of Punxsutawney, Pennsylvania, crowds of people waited for the weather prognosticating groundhog named Phil to emerge and make his annual prediction about how much more winter there would be this year. If the large rodent sees his shadow, then there will be six more weeks of winter. If he doesn’t see his shadow, then there will be an early spring. If you live ...

Removing Worst Water Weeds #8 :Sargassum with Weedoo Workboats
Nothing ruins a trip to the beach like having to navigate around or through piles of rotting seaweed to get to the water. This is why Sargassumhas earned a place on our list of the worst water weeds. This genus of macroalgae (seaweed), started making headlines back in 2015 when huge amounts of it started piling up and decaying on lovely Caribbean island beaches such as the Dominican Republic, ...

Worst Water Weeds #7: Phragmites Australis
This particular plant is widely known as the “common reed,” but the havoc it is causing on wetlands in various parts of the United States is anything but, which is why it definitely makes our list of the worst water weeds. In the world of scientific botany, the genus is known as Phragmites, with four main species found in different parts of the world. Only one of those four species, ...

Protecting the Arctic from oil spills
Once the far north was untouched by anyone except explorers. Now that there is more activity in the Arctic there is a need to protect it from oil spills. The Arctic region is opening up to more human activity. Climate change and advances in icebreaker technology are making the idea of a northern passage for commercial shipping a reality. More resources are being spent on studying the Arctic, ...

Understand the location very well before you purchase any oil spill response equipment
I love sports, football, tennis, surfing, ping pong, etc. and I always related that to the fact that I was very conscious in relation to the environment. In my eyes, sporty people have a higher tendency to protect nature. After finishing my studies in Finance and International Business, I ended up (as you do) working as an Oil & Gas Engineer in the UK with my very strong Peruvian accent. At ...

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 recovery ...

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 energy ...

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 ...

Port of antwerp oil spill soil remediation project case study
THE PROBLEM In 1990, 4500 m3 of silty sand/soil contaminated with mineral oil (diesel) to a level of 1500 ppm was treated on-site (Port of Antwerp) at the request of the client. OUR APPROACH On reviewing both the site and the scope of the project it was clear to Nordevco staff that the most cost effective and efficient approach would be to treat the soil in a modified soil pile/wet cell using ...

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 ...

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 ...

Remediation of silty-clay hydrocarbon contaminated site using Ivey-sol selective phase transfer technology
Earlier this year, Ivey International Inc. secured its first remediation project in Alberta using its Ivey-sol Selective Phase Transfer Technology (SPTT). This patented technology is being used to treat extensive soil and groundwater contamination at an active service station in Red Deer, Alberta. With a residential area nearby, the environmental sensitivity is relatively high. Unfortunately, ...

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 bolstered in dozens of locations around the United States through the use of a rather simple system. The concept is simple – a polymer “sponge” that removes contaminants from water before it winds up passing ...

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 ...

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 ...
