Published: December 2021

In situ burning (ISB) is an OSR (Oil Spill Response) technique generally not accepted as a “standard” response by most regulators. Main reluctance generally comes from the occurrence of large and dark smokes plumes as well as possible heavy burn residues likely to sink and reach the seafloor. However, ISB has been widely used during the Macondo oil spill in 2010 and highlighted as a promising operational technique. Additionally, standard OSR modeling tools do not consider ISB, as there is a lack of knowledge in the capacity to predict accurately the physico-chemical characteristics, fate and ecotoxicity, of the burn products from large varieties of crude oils.
In order to provide dispassionate arguments, we have conducted a study to gain knowledge and try to develop predictive capabilities to infer composition and fate of burn products from characteristics of starting crude oils. The study comprises both large literature review and experimental work where six crude oils of different types (along with corresponding weathered oils) were burnt, and all products quantified and analyzed (physico-chemistry), at both laboratory scale (burning bench) and pilot scale (fire platform). Additionally, ecotoxicity testing on Vibrio fischeri bacteria and Phaeodactylum tricornutum algae were conducted on crude and weathered oils, burn residues, water and soot. The fate of burn residues was also investigated through dispersibility, emulsification and biodegradability testing. The experimental work led to a very large set of data which was subject to multivariate regression statistical treatments to build predictive models. Main data investigated were burn efficiency, density, viscosity, SARA (Saturates, Aromatics, Resins, Asphaltenes) composition, n-alkanes and PAHs (polycyclic aromatic hydrocarbons) distributions in burn residues, gas emissions composition, soot' PAHs distribution in the smokes, and ecotoxicity data of burn residues, soot and water. The paper describes the main results of this study, with promising outcomes to develop predictive ISB modeling and help addressing objectively the relative impact of ISB within the SIMA process in comparison with other cleaning responses.
Overview of surveillance tools in oil spill response – responders' view based on case studies
Authors: Januszewska Marta 
Published: December 2021

ABSTRACT
With a growing market of new technologies in surveillance for oil spill response, it has become increasingly difficult for users to understand which surveillance tool is best suited for their requirements. Oil Spill Response Organisation's (OSROs) such as Oil Spill Response Limited (OSRL) require an easily-deployable, yet durable solution available to be utilised in a range of working conditions. The surveillance platform and type of sensor will be heavily influenced by the response scenario.
This paper provides an overview of surveillance platforms such as the surveillance kite, UAV's (Unmanned Aerial Vehicles) and tethered balloon utilised by OSRL in different response scenarios on real incidents. The examples include offshore and shoreline incidents and exercises with offshore and shoreline response elements. In each of the examples the focus will be on the advantages and disadvantages of the surveillance tool chosen for the task, and lessons learned from each case/experience.

Historically, visual observation is an emergency responder's first ‘tool’ in identifying spilled oil. Optical detection has since expanded to include a myriad of signals from space, aircraft, drone, vessel and submersible platforms that can provide critical information for decision-making during spill response efforts. Spill monitoring efforts below the air-water interface have been vastly improved by advances with in situ optical sensors and vehicle platform technology. Optical techniques using fluorescence, scattering, and holography offer a means to determine dissolved versus droplet fractions, provide oil concentration estimates and serve as proxies for dispersion efficiency. For subsurface spills over large space and time scales, Autonomous Underwater Vehicles (AUVs) can be used to provide subsurface plume footprints and estimate oil concentrations. For smaller, more frequent spills, tethered compact Remotely Operated Vehicles (ROVs) may be more appropriate as they are easy to deploy for rapid detection.
Two underwater oil detection technologies have been developed: (1) A Remote Environmental Monitoring UnitS (REMUS-600) AUV equipped with fluorescence and backscatter SeaOWL UV-A (Oil-in-Water Locator; Sea-Bird Scientific WET Labs Inc.), holographic imager (HoloCam; SeaScan, Inc), hydrographic information, video camera, CTD and a water/oil sampler. (2) A tethered ROV system (DTG2, Deep Trekker Inc.) equipped with video camera, UviLux (Chelsea Technologies Group, Inc) fluorometer, a CTD and water/oil sampler. Calibration and validation tests of the sensor suite were conducted at the Coastal Response Research Center flume tank (NH, USA). Oil concentration estimates were verified by chemical analysis of hydrocarbons and particle size analysis (LISST 200X, Sequoia, Inc). Operational performance of the ROV platform and sensors was evaluated at the Ohmsett wave tank (NJ, USA). Field performance of the REMUS and sensor suite was evaluated at natural seeps near Santa Barbara, CA. This research demonstrates the forensic value of in situ optical data for improved understanding of the behavior and transport of spilled oil below the air-sea interface.
Development of the Global Equipment Inventory and Network for Subsea Well Response

ABSTRACT 1141381
The Montara (2009) and Macondo (2010) incidents resulted in step change in safety for the oil & gas industry. Since then many improvements have been implemented to keep the highest standard of safety in drilling operations. Through industry collaboration subsea well response equipment not available at the time of these incidents is now globally accessible.
Technology continues to be developed to provide comprehensive response capabilities. A recent area of focus for industry was how to cap an incident well in water depths less than 600 meters where vertical access may not be possible due to hydrocarbons at surface and a possible gas boil in the case of a gas well. An innovative concept was developed, manufactured and tested to deal with a loss of well control event in shallow water.
The Offset Installation System (OIS) allows a capping stack to be deployed and installed on a blowing out well in shallow water, deployed and controlled by vessels offset from the incident well. In addition, the OIS can be used for debris clearance, removal of the lower marine riser package (LMRP), and deployment of other subsea response hardware.
By virtue of their source control operational function capping stacks are relatively large and heavy pieces of hardware. Despite these physical characteristics, there is expectation by stakeholders and international regulators for capability to transport capping stack equipment across significant distances in an expeditious manner to respond to an incident. For remote areas of the globe, capping stacks air transported as a single unit could provide an effective solution.
A key objective in responding to a subsea loss of well control event is the ability to effectively mobilise source control equipment and trained personnel to readily manage an emergency response scenario in a timely manner globally. A number of companies with a range of capabilities will be required to provide a comprehensive response. To further assist, initiatives focused on personnel resources have been developed including a global subsea response network, and continuing industry collaboration for mutual aid of personnel.
This paper will provide information on the development of the global subsea response equipment inventory available to industry. Latest developments such as OIS and air freightable capping stacks for transportation to remote areas will be discussed in detail as well as the above-mentioned initiatives for personnel.
Controlling mechanisms of burning rate enhancement while using Flame Refluxer technology during in situ burning of crude oil spills
Authors: Sauer Nathaniel , Pi Xiaoyue , Arsava Kemal , Rangwala Ali 
Published: December 2021

ABSTRACTThe focus of this study is to quantify the controlling mechanisms, which increases the burning rate of a pool fire using a Flame RefluxerTM. Part of the Flame RefluxerTM, is exposed to the fire and is heated up transferring heat to the fuel pool layer to which it extends. This enhances the conventional heat transfer that occurs only through the pool surface by transferring the heat from a fire to an in-depth layer of the liquid. Both sensible heat and heat of vaporization are supplied at increased rates by the submerged material. As an additional important effect, nucleate boiling onsets at the surface of the inserted material that generates bubbles of fuel vapor. These bubbles are transported to the surface of the pool, where they burst and release the v0061por to the gas-phase. While doing so, additional processes such as formation of micron-sized droplets or small jets of liquid fuel from the break point occur. This phenomenon causes additional fuel in liquid phase transported to the gas-phase, where they vaporize, ignite and burn in heterogeneous mode. Therefore, the processes involved in FR occur in three steps; enhancement of heat transfer to the liquid causing nucleate boiling, formation of bubbles and their transport, and dynamics of bubble breakage at the pool surface causing transfer of liquid fuel in the form of tiny droplets or jets towards the gas-phase. This study analyzes the influence of bubbles on the burning behavior of a pool fire using a simple experiment involving burning ethanol as a fuel. Ethanol is used due to its transparency and hence bubble behavior is easily observable on the heater surface. A 5cm x 5cm glass enclosure constantly replenished with ethanol serves as the burning pool. A solid aluminum block (8.8 cm tall x 3.6 cm wide x 1.2 cm thick) is placed in the flame to act as the Flame RefluxerTM. Bubble counts and burning rate measurements indicate the influence of the bubbles on the overall burning rate of the liquid pool.
How well prepared are countries in Latin America and the Caribbean? A Benchmarking Assessment for Oil Spill Preparedness and Response

Abstract ID 667973
A guide for best practices in spill response preparedness was presented to the international community over ten years ago during the 2008 IOSC. The published guide was the compiled effort of multiple government and industry stakeholder workshops representing the spill response community. Through ARPEL initiatives, the guide was transitioned into a free, user-friendly, spill response/readiness evaluation tool for oil spills (RETOS™) and its accompanying manual. RETOS™ is a scalable self-assessment tool that uses a broad suite of planning and readiness assessment criteria broken down into ten different categories to identify gaps in a response program. RETOS™ has subsequently been used in over 50 countries to assess the status of oil spill readiness and preparedness for national to local facility spill response programs. The benchmarking evaluation identifies gaps and opportunities for improvement, priority areas for development, and establishes a baseline against which program improvements and regional, or complementary, response programs can be gauged.
RETOS use in Caribbean and Latin America countries, instigated through the RAC-REMPEITC and ARPEL, has promoted national plan development, program improvements, and regional cooperation. National programs assessed at a base level using the RETOS™ application revealed scores between approximately 30 and 90% in these regions. National assessments from countries throughout region and a survey of RETOS users, most of whom utilized the tools for assessing national spill response programs, reveal areas that are common challenges for many of the small island and/or developing nations. These encompass financial matters, training and exercises, and sustained improvement. Several countries in the region have conducted subsequent assessments and in some cases have shown as much as 60% improvements in program readiness.
When RETOS™ is used on a regional scale, specific national program gaps can be compiled and analyzed regionally. This analysis can drive future IMO activities to address regional gaps and areas for improvement, highlight specific areas for bi-lateral and multi-lateral mutual aid agreements, and can provide regional solutions to national problems, such as creating and maintaining a database of oil spill equipment and experts available in the countries of the Region. Updates to the ARPEL RETOS™ tool and Manual, continued published guidance on best-practices, and repeated self-assessment efforts are recommended to sustain spill readiness improvements. The RETOS™ tool has proven to be an integral part of national and regional oil spill program assessment and directly contributes to overall oil spill program improvements.
Evaluation and Comparison of Current Emulsification Algorithms and Their Uncertainty in Oil Spill Modeling Software

Published: December 2021

Oil spill risk assessments (OSRAs) do not currently distinguish between potentially more toxic, fresh crude oil and less toxic, highly-weathered residues which limits the understanding of the highest risk areas to prioritize mitigation measures and allocate response resources. Fate and trajectory models, used commonly for OSRA, have advanced significantly over the last five years now with enhanced ability to model chemical and physical parameters at greater resolution. Using this enhanced resolution, modelers may be able to provide some indication of the weathered state of the oil as input to the OSRA. In order to evaluate the degree of certainty in such a prediction, it is necessary to better understand the uncertainty in the modeled weathering processes that influence the toxicity of the oil. Emulsification plays a significant role in modeling of oil thickness (and therefore photo-modification), evaporation, and dissolution which are important modulators of oil toxicity. In this project, the emulsification algorithms of three currently available fate and trajectory models, ADIOS, OILMAP/SIMAP, and OSCAR, were evaluated to gain a better understanding of the degree of certainty in the modeled weathered state of oil.
In this work, the basis of emulsification algorithms implemented in the models referenced above were identified, and it was found that each of these models incorporates emulsification differently. ADIOS2 relies on emulsification data gathered from mixing oil and water in a food processor. An updated version of ADIOS2 (ADIOS3) is based on a new formulation that is dependent on measured SARA components of the oil, but is still under construction and is not yet implemented. OILMAP/SIMAP use the algorithm presented in Mackay and Zagorski (1982). OSCAR uses a water uptake algorithm that was calibrated to in-house laboratory experiments. Further investigation into the development of each of these emulsification algorithms provided insight into the degree of uncertainty in these models and their input parameters, and what oil types may not be appropriately characterized by the implemented emulsification model. Additionally, the impact of that uncertainty on oil fate was investigated by evaluating the changes in the amount of emulsification when modifying user input parameters within realistic assumption ranges. The findings and comparison of the implementation of these emulsification algorithms and the sensitivity of the results to different inputs is presented here.
Resourcing the next industry defining spill
Authors: Hall Sarah , Rouse Dave , Foley Paul , Montgomery Aaron 
Published: December 2021

Abstract
The Deepwater Horizon (DWH) response was unprecedented in scale and complexity. In addition to testing the limits of Industry's technical knowledge, it required a sustained response of personnel effort over several years. At the peak of the response, some 47,000+ responders were deployed across five states. For any future incident of similar scale the challenges of resourcing must be considered now, to ensure a timely, efficient and effective response can be achieved.
Whilst the contribution of every responder is important, it is clear that some command and field roles are more critical than others. For these key roles there are a limited number of individuals with the knowledge, experience, credibility and personality to successfully take them on. Furthermore, accessing these individuals - having up-to-date contact details, maintaining business continuity and assuring their competency - is a challenge.
Another common preparedness gap is that most exercises do not test the process for mobilising people past the first few days (thereby not learning lessons about the time it takes) or consider the challenge of putting people in place with the right skill set during a prolonged response. DWH was resourced using the ‘little black book' of contacts from oil spill response organisations (OSROs), Oil and Gas operators, scientific experts and the local communities. Whilst successful, there were lessons to learn from the approach.
In the last 10 years the expectations from regulators, public and other stakeholders on the speed, transparency and effectiveness of response have multiplied. To meet these growing expectations a more robust and efficient way of putting the right people, in the right place at the right time is required. This poster discusses the merits and suggests a potential mechanism for a globally aligned mutual response network.
Oil spill response cooperatives are ideally positioned to identify key roles, the people who could fill them, assure their capability and readiness, and address the barriers which slow down mobilisation such as agreeing contracting terms and rates. This poster will lay out the challenges that both Industry and OSROs face in resourcing the next industry defining spill. It will set out how an oil spill mutual response network answers these questions. It will also reinforce why collaboration and cooperation, key principles of Tiered Preparedness and Response, will continue to be the most efficient and effective way of accessing capability and maximising Industry's preparedness to respond to the next big incident.
Monitoring sea surface oil slicks; a combined approach using advances in satellite radar, AIS and Metocean information

Published: December 2021

AbstractIn recent decades, industrial activity in the marine environment has dramatically increased. Dense offshore infrastructure combined with an increase in shipping activity creates a complex blend of potential oil pollution and environmental risk.Over the last year, CGG Satellite Mapping, supported by the European Space Agency's business applications, Oil Spill Response Limited and key oil and gas companies, created and managed a SeaScope monitoring demonstration service. SeaScope confirms the presence or absence of slicks around infrastructure; reports on the integrity of operations based on slicks observed; identifies the potential origins of pollution slicks or permitted discharge; and has the ability to distinguish between pollution and natural seepage by using routine satellite monitoring.This paper describes how advances in Earth observation radar combined with AIS (Automatic Identification System), metocean data and experts trained in the interpretation of offshore satellite imagery, can be used to regularly monitor sea surface oil slicks and notify offshore operators of anomalous events within the vicinity of offshore infrastructure and high density shipping areas.
Coastal Communities and Response Planning
Authors: Lowry Michael , Heaney Lincoln 
Published: December 2021

Abstract
The Coastal Response Program is a Western Canada Marine Response Corporation (WCMRC) initiative that brings existing response programs under one umbrella. The objective is to enhance these interrelated initiatives and ensure they have coordinated support to maintain an operational ready state. The program improves WCMRC's overall capacity by building strong relationships with industry, coastal communities and First Nations by involving them in spill response in a meaningful way. This paper will provide an update on how WCMRC is rolling out the program on Canada's west coast and will discuss some of the benefits and challenges that WCMRC has experienced. While local issues will bring unique challenges to every jurisdiction, some of the broader principles of the community involvement under the Coastal Response Program can help other response organizations and coastal communities be better prepared.
