Polluting shipwrecks in Swedish waters: investigations, risk assessment methodology and oil removal operations
Authors: Lindgren J. Fredrik , Åberg Frida , Johansson Josephine Rubia 
Published: December 2021

ABSTRACT
Large amounts of oil exists in old shipwrecks worldwide, both as cargo and bunker. This oil will eventually enter the marine environment as the ship hulls deteriorate or as other types of activities affect the wrecks. Oil being a complex mixture of hazardous substances will when released into the marine environment be a source of both lethal and sub-lethal effects to organisms. Costs of an oil spill in the marine environment, including clean-up actions, socioeconomic and environmental costs is often substantial. Sweden has a ten year nationally funded program where oil removal operations on shipwrecks are performed. From a list of 300 potentially polluting shipwrecks, 31 wrecks have initially been selected for oil removal operations. In a first stage extensive gathering of information was performed regarding each wreck, both archive data and in-situ data at the wreck site. Secondly, a risk analysis was carried out. Based on the probability of oil leakage, amount of oil in the wreck and sensitivity of recipients, a prioritization for oil removal operations was made of the 31 wrecks. Based on the prioritization, time of the year and cost of an operation wrecks are finally selected for oil removal operation. So far, since 2017, five operations have been performed.
During 2019 and 2020, two successful oil removal operations were carried out. The ship Lindesnäs wrecked 1957 in a snow storm close to the lighthouse Norra Kränkan on the Swedish east coast with a cargo of kerosene and diesel as bunker fuel. The operation from mobilization to demobilization lasted for 22 days, and 299 m3 of oil and a large ghost net was removed from the wreck. Secondly, Finnbirch, which wrecked in 2006 east of the island of Öland and started to leak oil during the end of 2018, was salvaged in a two-part operation. In 2019, 60 m3 of diesel fuel and lubricant oil were salvaged, during a fourteen-day operation. In 2020, 114 m3 of heavy fuel oil (HFO) was salvaged from the wreck during a fifteen-day operation. The costs per ton of removed oil were far less than cost for oil clean-up operations in Swedish waters. In conclusion, using a risk-based approach for prioritization of potentially polluting shipwrecks and the subsequent proactive removal of oil from shipwrecks is a cost-effective approach to alleviate the problem.
Bridging research to response – how the spill response community benefits from academic engagement

ABSTRACT
Often technical advances are made through key industry-academic alliances in a diverse range of engineering, medical and scientific disciplines. Oil spill response studies are no stranger to research programmes within the academic / R&D community and have advanced our knowledge, understanding and capability significantly over the last 50 years. For example, following the use of industrial detergents during Torrey Canyon in 1967, the research, development and scientific rigour behind the latest marine dispersants is testament to the value in investment of resources to develop and deliver solutions to new and emerging risks.
Typically, spill responders are focussed on operational issues and seeking maximum reward when selecting a response technique(s) as part of a given spill scenario. Research scientists conversely may be focussed on a more detailed aspect of the spill such as a sub-cellular, non-lethal biological effect which may have limited relevance to the immediate clean-up effort. Having a spill response organisation intrinsically involved with academic response research ensures that an element of “operational realism” is injected into the programmes to produce outputs with more direct relevance and application to advance the boundaries of future spill response techniques and capability.
The paper discusses the merits and leverage potential of “Bridging Research to Response” and offers suggestions for future collaborations potentially adding value to all spill stakeholders.
Geographic Response Strategies on Canada's West Coast
Authors: Gardner Jocelyn , Ostrowski Stefan 
Published: December 2021

Abstract
In 2012, Western Canada Marine Response Corporation (WCMRC) began developing site specific shoreline protection strategies, known at Geographic Response Strategies (GRS) for the entire coast of British Columbia (B.C.). The project started in Vancouver Harbour and has since spread along the Salish Sea and Strait of Juan de Fuca, as well as into Prince Rupert and Kitimat on the northern B.C. coast. Recognizing that B.C. has approximately 27,000 km of coastline (~16,777 miles) and with 450 strategies already developed only within a few hundred kilometres, WCMRC saw a need to automate the GRS development process from data collection all the way to the final GRS output. In conjunction with a local environmental consulting company, WCMRC developed a new sensitivity model. This new model can help the Response Readiness Team quickly assess intertidal sensitivity to oiling based on shoreline type, oil residency index, biological, archaeological, and/or socio-economic features of the shoreline, as well as operational protection feasibility. Now, using ESRI GIS web tools, a GRS can be developed automatically as a geo-referenced PDF, easily exportable to mobile devices for operational use. Overall, the automated enhancements have provided WCMRC with the tools necessary to manage the GRS program for B.C.'s entire coast. This means that more coastline can be assessed far more quickly and GRS's can be developed using fewer human resources. Additionally, if a spill occurs in a more remote area that has not yet had GRS's developed, they can be created within minutes based on the information from the Environment Unit in the Incident Command Post, or initial assessments by responders.
The Multi-Partner Research Initiative: A Scientific Research Network to Support Decision Making in Oil Spill Response
Authors: Lee Kenneth 
Published: December 2021

ABSTRACT
The Government of Canada's Oceans Protection Plan (OPP) is a comprehensive, transformative $1.5 billion strategy to build a world-leading marine safety system to protect marine ecosystems, while enabling inclusive economic growth. A key component of the OPP is the Multi-Partner Research Initiative (MPRI), led by Fisheries and Oceans Canada (DFO) in collaboration with other federal agencies (Environment and Climate Change Canada, Canadian Coast Guard, Natural Resources Canada, and Transport Canada), that aims to advance oil spill research by fostering a national/international research network that brings together scientific experts in the field. The core studies under this program are focused on the provision of scientific knowledge to support the development, validation and regulatory approval of Alternative Response Measures (ARMs) that include: spill treating agents, in situ burning, oil translocation and decanting/oily waste disposal. Additional research includes studies on key “cross-cutting” issues, such as natural attenuation and bioremediation of oil, assessment of toxic impacts associated with oil spills and the application of oil spill countermeasures, and oil detection and mapping by autonomous underwater vehicles (AUVs). The deliverables from this research program will provide essential information to support Net Environmental Benefit Analysis (NEBA) for decision making to select the optimal oil spill response option(s) to protect the marine environment and its living resources. With an emphasis on supporting the development of the next generation of scientists in the field through engagement with the private sector (i.e., spill response organizations and oil industry partners) and other international (e.g., USA, Norway, France, Australia, China) government agencies, MPRI is anticipated to have a profound influence on the oil spill research community and emergency response agencies within Canada and abroad.
SpiDeR –Spill Detection and Recognition system for ROV operations
Authors: Pocwiardowski Pawel 
Published: December 2021

ABSTRACT
The paper presents the outline of the Spill Detection and Recognition system – SpiDeR and its application to underwater oil and gas detection, classification and source characterization demonstrated in the remote-sensing survey of Mississippi Canyon area in the Gulf of Mexico founded by BSEE in 2017. The main objective of the operation was to deploy sensor package from a remotely-operated vehicle (ROV) to survey, detect, and map the location(s) of hydrocarbon emissions that are responsible for the surface oil spill and sheen footprint in the Mississippi Canyon Area. The objectives have been accomplished by conducting a multi-day, three-part survey mapping the area of interest, generation of georeferenced charts and 3D visualizations with detected oil active spills, all supported by a ROV intervention outfitted with oil spill detection and recognition system SpiDeR.
SpiDeR is a modular sensor suite capable of detecting, recognizing the source and classifying the hydrocarbon underwater leaks. The sensor suit with selectable configuration can be installed on any type of ROV vehicle and interfaces to the ROV with a single cable conducting the power and data. The presented here and used during the mission complete sensor suite consist of two 3D, broad band, electronically scanning multibeam sonar systems NORBIT WBMS STX, one Forward Looking Sonar NORBIT WBMS FLS, fluorescent oil classifier LIF – Laser Induced Fluorescence detection unit and the video camera with lights.
The most useful capability of the SpiDeR is the ability to generate 3D imagery (georeferenced bathymetry) even when the ROV is not moving. That combined with time gives 4D observable capabilities of the oil spill. The 4D capabilities have been proven useful during the u-bathymetry part in Phase 2 and forward-looking 3D in Phase 3 of this mission.
The system has been deployed from the ROV in the area where it has been known for the last decade that the leak of hydrocarbons is coming from. The real task at hand was to recognize the leak source and that source contain hydrocarbons and accurately document the source location and provide measurable documentation of its character.
California's Stakeholder Matrix: A Liaison Tool for the first 96 hours of Response
Authors: Addassi Yvonne Najah , Shinn Cassidee 
Published: December 2021

ABSTRACT
Research on crisis and risk communication continues to illustrate the need for and benefits of early and sustained stakeholder engagement during disasters, both natural and manmade. The California citizenry is deeply committed to environmental protection and expects to “engage” with their government on policy development and environmental solutions. Stakeholders expect a high-level of government transparency, driving the need for engagement even more during emergency responses such as oil spills.
Within the Incident Command System (ICS), it is the responsibility of the Liaison Officer (LOFR) to coordinate and share information with stakeholders. A review of “After Action Reports” and “lessons learned” from oil spills, both nationally and within California, point to the continued need for strong stakeholder engagement by the LOFR and has become a priority of California's lead oil spill response agency, the California Department of Fish and Wildlife, Office of Spill Prevention and Response (OSPR).
Building off stakeholder engagement tools found in crises and risk communication literature and in Incident Command System job aids, OSPR crafted a stakeholder matrix that was readily scalable, easy to use, and easy to translate to Incident Commanders and other Command Staff during response. This matrix is a template of simple inputs, allowing stakeholders and engagement strategies to be identified, grouped, and prioritized. It is intended to be a planning tool for the first 24–96 hours, a precious time in a response. It is often too early to expect the LOFR to have completed a stakeholder engagement plan, yet this time is critical to initiating early stakeholder communication that will set the tone for the response. This matrix serves as the initial plan for the LOFR. This paper will describe the development of this tool, its evolution, and its use. It will also highlight feedback from exercises and response partners. It will describe the flexibility and scalability, and considerations for broader applications.

ABSTRACT - 687127
Most oil spill response strategies, tactics, and equipment are designed to address floating oil. Previous research and historic events have shown that spilled oil can suspend (i.e., submerged oil) or sink (i.e., sunken oil) as a function of the oil's density relative to that of the receiving waters. Processes such as wave action or current velocity, sediment entrainment, and oil weathering (e.g., evaporation) may change the buoyancy of floating oils causing them to submerge or sink. Non-floating oil is more difficult and expensive to detect and poses significant challenges for containment and cleanup. Many existing detection techniques for non-floating oils rely on oleophilic sorbents, such as snare, which are weighted depending upon the oil's location in the water column and then towed behind a vessel in designated transects. Currently, there is no quantitative method to relate the amount of oil collected by snare to the amount of oil encountered during towing. In addition, the dynamics and interactions of towed snare and oil remain largely unknown. To address these knowledge gaps, various components of snare performance have been evaluated since 2016 by the Coastal Response Research Center (CRRC) at the University of New Hampshire (UNH).
The research has evaluated: (1) the impacts of temperature, salinity, oil type, and tow velocity on adsorption and desorption of oil to snare, (2) snare dynamics and position in the water column as a function of tow velocity, (3) the impacts of material type and potential alternatives to snare (e.g., mosquito and fishing nets, plastic debris) for lesser developed countries (LDCs), and (4) the interaction of snare with sunken and submerged oil. The results determined: (1) adsorption of oil to snare was best for less viscous oils (No. 6 Fuel Oil) and lower water temperatures (5°C) and desorption was greatest at low temperatures (6°C) and low current velocities (&lt; 1 knot), while salinity had no significant effect. (2) Tow depth for snare arrays decreased with increased velocity unless a vane was used. (3) Optimal spacing of snare on a chain is a function of tow and current velocity, and drag forces on the tow chain. (4) Snare alternatives with greatest potential for sunken oil detection in LDCs were nylon mosquito netting and plastic bags. The findings from this research improves understanding of the behavior of snare and how it interacts with sunken and submerged oil and can improve towing techniques used by oil spill responders, leading to more effective detection.
Understanding the Fates and Chemical Compositions of Weathered Oil in Coastal Marshes since the 2010 Deepwater Horizon Oil Spill

Abstract
Coastal marshes were heavily impacted by the Deepwater Horizon (DWH) oil spill in 2010, with approximately 90% of shoreline impacts occurring in Louisiana's coastal wetlands. Spilled crude oils impact an environment through four major mechanisms: ecosystem exposure to reactive and toxic aromatic compounds; covering and smothering that hinders normal plant and animal physiology; depletion of dissolved oxygen; and disruption of the aquatic food web. Crude oil's ability to cause environmental harm depends upon its composition, which is a very complex mixture of many thousands of reduced carbon compounds made from the degradation of plant material deposited deep underground. This study reviews the results from the chemical characterization of petroleum hydrocarbons, at various weathering stages, in &gt;2000 marsh surface sediments and select sediment cores samples collected from various sampling locations in Terrebonne Bay, Grand isle, and northern Barataria Bay from 2010 to 2018. The sediment samples were analyzed for target saturated alkanes, polycyclic aromatic compounds, and the forensic biomarker (hopane and sterane) compounds. The chemical characterization of the compositional changes of target compounds in DWH oil, from its pre-stranding stage just offshore in the Louisiana Bight, through stranding on marshy shorelines and through its degradation and weathering over eight years has given insights into the complexity of oil residues and potential for impacts in these varying environmental conditions. Stranded oil initially had two prominent fates: settling on surface sediment/soils of the marshes, and subsurface deposition primarily by means of settling into fiddler crab burrows. Both initial fates affected shorelines and 10–20 meters inward. Over time, surface oil residues were spread beyond initially impacted areas by Tropical Storm Isaac in 2012 and other weather events, and oil residues were quickly degraded. Subsurface stranded oil was degraded much more slowly under anaerobic conditions and some was re-released as fairly fresh oil during the coastal erosions caused by DWH surface oiling damage to the marsh plants. However, these re-releases were relatively slow and were quickly aerobically degraded once the stranded oil reached marsh surfaces. There was also evidence of anaerobic degradation of heavily weathered surface oil residues during the 2015 to 2018 timeframe. This eight-year study establishes a very complex narrative between the physical and chemical properties of stranded oil and its interactions with coastal marsh environments.
Advanced Well Control Reduces Risk of a Blowout
Authors: Nedwed Tim , Mitchell Doug 
Published: December 2021

AbstractThere are still concerns about well control especially for operations in sensitive environments. Currently the final barrier while drilling oil and gas wells is a valve system (blowout preventer or BOP) located on top of wells. These valves can isolate wells by sealing around or shearing through obstructions in the well (e.g. drilling pipe and casing). If these valves fail or if some other barrier in a well fails, hydrocarbon loss to the environment is possible. Adding barriers capable of responding to a well control loss could alleviate these concerns. ExxonMobil is currently evaluating concepts to provide two additional methods to kill an out-of-control well. One utilizes rapid crosslinking polymers to form a polymer-plug seal inside a BOP after a failure. The other is to rapidly pump seawater into a well to produce back pressure that overpressures the entire well bore to keep hydrocarbons from escaping oil / gas bearing zones.Mixing dicyclopentadiene (DCPD) and other monomers with a ruthenium-based catalyst causes a rapid polymerization reaction that forms a high-strength, stable solid. These reactions can occur under extreme temperatures and pressures while withstanding significant contamination from other fluids and solids. The well-control concept is to rapidly pump the monomers and catalyst into a leaking BOP to form a polymer seal that prevents further flow.The seawater injection concept uses high-pressure and capacity pumps located on a surface vessel and a conduit from these pumps to a port on a BOP. If a blowout occurs, seawater at high rate is pumped in the BOP. If BOP seal failure is the reason for containment loss, then the seawater will overpressure the BOP and seawater will displace the hydrocarbons passing through the leak point. Seawater injection will also overpressure the entire wellbore to keep hydrocarbons from escaping anywhere in the well. For example, if a leak occurs deep in the well, seawater injection into the BOP will overpressure the entire well and the seawater will replace the hydrocarbon flowing through the leak point.We have conducted testing of the polymer plug concept at representative temperatures and pressures using a small-scale BOP. Polymer seals were formed when the scale BOP was flowing drilling mud, a crude-oil surrogate, and water. The seals held up to 5,000 psi pressure for almost 18 hours. We have completed modeling of the seawater injection concept to define pumping needs. This paper describes the current status of concept development.

ABSTRACT
In 2015, an ambitious wildlife response preparedness project was initiated; funded as part of the post-Macondo IPIECA-IOGP (International Association of Oil and Gas Producers) Oil Spill Response Joint Industry Project (OSR-JIP). The Global Oiled Wildlife Response System (GOWRS) Project, which involved 11 leading wildlife response organizations from seven countries, aimed to develop an international framework for oiled wildlife response as well as encourage the further development of wildlife response preparedness by industry and other stakeholders. This paper will provide an overview and assessment of the key outcomes of both the JIP-funded phase of the project (2015-16; development of internationally agreed standards and common operating procedures) and the second industry-funded phase (2017-18; focused on response readiness) in order to provide key background information to support the movement towards operationalizing the system.
Net Environmental Benefit Analysis Embedded Action Plan Development
Authors: Peach Dennis , Taylor Kirstin 
Published: December 2021

Abstract
During a response to an oil spill the responsible party needs to develop Incident Action Plans that aim to minimise the environmental and socio-economic effects of the incident on the surrounding area.
It is widely accepted that Net Environmental Benefit Analysis (NEBA) and the Spill Impact Mitigation Assessment (SIMA) methodology should be considered before, during and after any spill response. However, during the initial response phase, actions are typically reactive. Decisions may therefore be based on the needs of the response, media or the local inhabitants rather than the long-term benefits to the affected area.
But how can we confirm that when the strategies and tactics are developed NEBA/SIMA is taken into account? To ensure that all response options chosen have considered NEBA/SIMA, especially during the initial stages of a response, it should be embedded into the action plan development process. This will also capture the decision-making process for the strategy and tactical plan development as evidence.
This paper explores where an Incident Management System (IMS) could be amended to ensure that NEBA/SIMA is integrated into decision making. This should guarantee that NEBA/SIMA is always considered in determining the correct response operations that capitalize on the net environmental benefits for the response. The process will follow the IPIECA/IOPG good practice guidelines for incident management implementation of IMS and contest the existing formal processes found in Incident Command System (ICS).
