An algorithm for detection of crude oil spills in visible light images has been developed and tested on 50 documented crude oil spill images from Shell Petroleum Development Company (SPDC) Nigeria. A set of three 25 x 25 pixels crude oil filters, with unique red, green, and blue (RGB) colour values, homogeneity, and power spectrum density (PSD) features were cross-correlated with the documented spill images. The final crude oil spill Region of Interest (ROI) was determined by grouping interconnected pixels based on their proximity, and only selecting ROIs with an area greater than 5,000 pixels. The crude oil filter cross correlation algorithm demonstrated a sensitivity of 84% with a False Positive per Image (FPI) of 0.82. Future work includes volume estimation of detected spills using crude oil filters, and utilizing this information in the recommendation of appropriate spill clean-up and remediation procedures for the detected spills. Keywords: Crude Oil Spill Detection, Crude oil image filters, Cross correlation, Visible sensor imaging, Oil Spill Segmentation.

A superhydrophobic fabric was first fabricated by a novel mussel-inspired strategy with the aid of folic acid and a low concentration of dopamine without any additional nanoparticle incorporation. A mini boat of this fabric can automatically recycle oil spills while floating freely on water.

ABSTRACT In July 1981, a crude oil spill from a pipeline break occurred in Osito Canyon near Castaic, California. In April 1984, a tank truck accident on Interstate Route 5 resulted in a fuel oil spill into a tributary canyon to Osito Canyon. Although the spills occurred at virtually the same location, the amounts spilled, the extent of the canyons contaminated, and the cleanup methods used produced different recovery results. The spillers assumed financial responsibility for cleanup actions and complied with the concerns and recommendations of government officials. The Environmental Protection Agency served as the on-scene coordinator, while the U. S. Forest Service and the U. S. Coast Guard's Pacific Strike Team provided on-site monitors and technical assistance. Impact from the spills appeared to be negligible on the chaparral type vegetation and sparse concentration of wildlife in the area. Effects from the spills were not lasting, and no environmentally sensitive downstream areas were affected.

ABSTRACTThere are few feasible options for sorbents, which can be quickly manufactured and deployed in the event of a major oil spill and so every oil spill is an ecological disaster. This paper aims to provide an understanding of what a realistic, full-scale crude oil spill solution would look like based on the performance of the best sorbents currently available, their costs, and their advantages.Adsorbent materials or “sorbents” described here have been a recent target for research toward applications in environmental cleanup, remediation, and hazardous material containment. These materials contain many compositions, syntheses, and practical manufacturing parameters that make most of them practically and logistically unfit to tackle quantities much larger than a single barrel of oil. Different properties of crude oil and nonpolar materials, such as their viscosity, density, and weathering, can also make these materials seem attractive on a lab scale but underperform in field testing and in practical applications. This review addresses the challenges, advantages, and disadvantages of different technical applications of the superior sorbent materials and material types in the literature. In addition, we discuss the different costs and manufacturing challenges of sorbent materials in real oil spills and what a feasible containment sorbent material might look like.

Abstract Offshore terminal usually performs crude oil lifting process regularly every 7-8 days. However, three repetitive leaks in crude oil subsea pipeline 36" MOL SPM-1 to SPM-2 occurred in the offshore terminal area had stopped the natural oil lifting process. Due to complex conditions, leak repair needs a longer duration and some future crude oil lifting schedules facing cancelation possibilities. By simulating the leak parameter, more than 60 bbl. of crude oil would release from the leaking pipeline in 48 hours crude oil lifting operation. An innovative approach is built by designing a new tool to contain oil spills from the source using a pyramid shape tank and safely transport to the temporary storage tank on the diving vessel to keep crude oil lifting process execution still possible to hold while the subsea pipeline repair by installing subsea clamp is undergo. New tools have successfully eliminated oil spill spreading during crude oil lifting takes place schedule. Six crude lifting schedules have been safely delivered with nearly 30,000 liters of crude oil spill have been evacuated and transferred back to processing facilities. Further implementation would possibly be held in pipeline preservation program and diver less application, which can increase leak response time.

ABSTRACT This article examines the potential for benzene exposure during crude oil spill response. Literature review found that under normal conditions benzene is lost from an oil slick within 40 minutes to 8 hours. A correlation between benzene and API gravity is presented graphically. This information was used to develop worst-case scenarios. Results of a preliminary field investigation indicate that benzene overexposure may be possible during “ideal adverse” conditions. Four generic crude oil spills are described along with rationale for the suggested level of self protection.

Crude oil spills are a major threat to marine biota and the environment. When light crude oil spills on water, it forms a thin layer that is difficult to clean by any methods of oil spill response. Under these circumstances, a special type of amphiphile termed as “chemical herder” is sprayed onto the water surrounding the spilled oil. The amphiphile forms a monomolecular layer on the water surface, reducing the air–sea surface tension and causing the oil slick to retract into a thick mass that can be burnt in situ. The current best-known chemical herders are chemically stable and nonbiodegradable, and hence remain in the marine ecosystem for years. We architect an eco-friendly, sacrificial, and effective green herder derived from the plant-based small-molecule phytol, which is abundant in the marine environment, as an alternative to the current chemical herders. Phytol consists of a regularly branched chain of isoprene units that form the hydrophobe of the amphiphile; the chain is esterified to cationic groups to form the polar group. The ester linkage is proximal to an allyl bond in phytol, which facilitates the hydrolysis of the amphiphile after adsorption to the sea surface into the phytol hydrophobic tail, which along with the unhydrolyzed herder, remains on the surface to maintain herding action, and the cationic group, which dissolves into the water column. Eventual degradation of the phytol tail and dilution of the cation make these sacrificial amphiphiles eco-friendly. The herding behavior of phytol-based amphiphiles is evaluated as a function of time, temperature, and water salinity to examine their versatility under different conditions, ranging from ice-cold water to hot water. The green chemical herder retracted oil slicks by up to ~500, 700, and 2500% at 5°, 20°, and 35°C, respectively, during the first 10 min of the experiment, which is on a par with the current best chemical herders in practice.

Traditional superhydrophobic material use depends on two processes: creating a rough structure on a material surface and modifying the rough surface with low surface energy materials.
