A device and method for dispersing oil on water comprises a rig structure for being mounted in a vessel, the rig structure including a front transverse structure with at least one nozzle for flushing with pressurized water supplied from a pressure facility located on the vessel.

FUNCTIONALIZED FOAMS

A method of fabricating an foam includes providing a foam comprising a base material. The base material is coated with an inorganic material using at least one of an atomic layer deposition (ALD), a molecular layer deposition (MLD), or sequential infiltration synthesis (SIS) process. The SIS process includes at least one cycle of exposing the foam to a first metal precursor for a first predetermined time and a first partial pressure. The first metal precursor infiltrates at least a portion of the base material and binds with the base material. The foam is exposed to a second co-reactant precursor for a second predetermined time and a second partial pressure. The second co-reactant precursor reacts with the first metal precursor, thereby forming the inorganic material on the base material. The inorganic material infiltrating at least the portion of the base material. The inorganic material is functionalized with a material.

Oil dispersant effectiveness monitoring

A process is provided for the determination of oil dispersant effectiveness. A submersible dispersant sensing platform is passed across a body of water. The platform has a plurality of sensors including a multichannel fluorometer and a particle size analyser, and each sensor produces an output data stream. The body of water is continuously analysed at a predetermined depth profile below the surface of the body of water. Hydrodynamic and environmental condition data is collected proximate in time and location to the output data from the dispersant sensing platform. The environmental condition data includes one or more of ambient temperature, body or water temperature, salinity of the body of water, wind speed, location, mixing energy of the body of water and derivatives thereof. Oil and dispersant data is provided which includes characteristics of the dispersant and of oil samples prior to the application of the dispersant. The output data stream, the hydrodynamic and environmental condition data, and the oil and dispersant data is processed to generate an indicator of the state of dispersion of the oil and of the oil dispersant efficiency under the hydrodynamic and environmental conditions the oil is exposed to. A system for the determination of oil dispersant efficacy is also provided.

Method and system is described to enhance operations for managing the hydrocarbon release. The method and system for managing a hydrocarbon release includes one or more vessels configured to collect mineral fines, to transfer the mineral fines to a hydrocarbon, and inject the mineral fines into the hydrocarbons at or near the hydrocarbon release location. The method may include subsea dredging or sediment collection in the vicinity of the mineral fines injection. This approach may be utilized to provide a continuous supply of material without interruption to injection operations.

Retraction of oil slicks using surfactants

A method for retracting oil on a water surface, and a method for reducing the quantity of oil on an oil control boom are described. Spreading of oil can be reversed by reducing the surface tension of the seawater, for example by using a low concentration of a water-soluble surfactant, such as a non-ionic surfactant. A controlled amount of the surfactant may be continuously discharged at the inner-wall of a spill control boom surrounding the oil spill. The spilled oil is caused to retract away from the boom toward the center of the area encircled thereby, such that the oil layer becomes sufficiently thick to be more effectively removed mechanically. The surfactant also reduces the amount of oil on the spill control boom, whereby the boom can easily be removed from a remediated oil spill and reused at a later date without further cleaning.

INTEGRATED MARINE BARRIER

A submergible marine barrier protecting marine installations in a protected zone against intrusion and providing a containment barrier against spread of floating spills or bodies. The body of the barrier is supported above water by a main body thus preventing intrusion and containing floating spillage. A weight in main body keeps the barrier upright, and a rigid floatation chamber in the main body keeps it afloat when full of air. A skimming pipe collects floating pollution. Flooding the floatation chambers causes the barrier to submerge allowing access to the protected zone and protecting the barrier from storms. Body, main body, and floatation chambers are made of extruded material with flotation properties (e.g. plastic pipes). Floatation chambers are connected by air hoses and have air venting tubes at their bottom. Sensors detect approaching intruders and pollution, while spikes, barbed-wire and diver-net or any known barrier are used to stop them.

Polysaccharide microgels for cleaning water of petroleum and petroleum products and method for using same (variants)

The group of inventions relates to the field of organic chemistry and can be used for cleaning water, industrial and domestic waste water or waste water sediment, and for the containment and recovery of petroleum and petroleum product spills in large bodies of water, rivers, lakes and seas.
