Offshore Oil Production

ABSTRACT In anticipation of the Beaufort Sea's first two offshore production islands, Alaska's North Slope oil producers recently expanded their oil spill recovery tactical plans and equipment. To seek regulatory approval for offshore oil production, industry responders joined agency regulators and made plans to clean up as much as 225,000 barrels of oil from potential blowouts over 15 days. Response technicians are configuring new and existing skimmers, vessels, and barges on the North Slope to implement those planning standards. This paper outlines the oil spill tactical plans and equipment that Alaska's North Slope oil industry recently assembled in seeking regulatory approval for the first offshore production islands in the Arctic. The operators of North America's largest oil fields are beginning the first production from oil wells separated from roads and most spill response vessels. For example, the new Badami production pad lies on the Arctic coast more than 25 miles from the Prudhoe Bay facilities, across river courses and roadless tundra. Eight miles of ice-infested sea will separate the proposed Northstar and Liberty production islands from response vessel berths. The new fields regularly experience waves, cold, and ice invasions that constrain oil recovery efforts. Yet regulatory approval to begin oil production requires that the industry have plans and equipment to clean up all the oil that may enter open water, even from the largest spills, within 72 hours.

Response Planning

AbstractThe North Slope of Alaska borders on two arctic seas, the Beaufort Sea and Chukchi Sea, with a total shoreline length of approximately 6,000 km. Oil exploration and production facilities are close to the coast, and the risk of spilled oil reaching the coast is increasing. The North Slope coast is a challenging location for spill response as the coastal areas are ice-covered much of the year and subject to variable ice cover during the open-water season. In addition, the shoreline is highly complex and rapidly changing because of melting of permafrost. The North Slope Coastal Imagery Initiative developed an online, decision support tool for spill preparedness and Incident Command decision making. The online tool makes more than 16,000 high-resolution images and 30 hours of high-resolution videography available to Incident Command in the event of a spill. Such high-resolution imagery is extremely useful in providing situational awareness for personnel unfamiliar to the Arctic and for tactical response planning. The resolution of the imagery is much higher than typical shoreline mapping or satellite imagery and, as such, eliminates ambiguity in interpretation when developing the most appropriate response strategies. The project provides a consensus building tool for spill response.

Perennial groundwater springs along the Alaska and Yukon North Slope provide overwintering habitat for various organisms, including birds and fishes. We observed an American Dipper, Cinclus mexicanus, in the open water of a perennial spring situated in Fish Creek, Yukon, in Ivvavik National Park on 8 March 2018. The observation at Fish Creek was among the most northern documented sightings of an American Dipper during the winter in North America. Moreover, the observation was approximately 650 km farther north than where American Dippers have been documented overwintering in Yukon, making this the most northern Canadian observation documented for this species in any season. Additionally, the American Dipper was photographed feeding on a juvenile Dolly Varden, Salvelinus malma. Although American Dippers are known to feed on small fish, our observation was a novel documentation of a trophic interaction between both species during winter. The open-water habitat in Fish Creek, which is important for both species and has not been previously described, was short (~730 m long), shallow (mean = 20 cm deep), narrow (mean = 2.8 m wide), and cold (mean water temperature = 0.34ºC). While there is little information regarding the ecological interactions of American Dipper overwintering in the Arctic, we note that all observations in the North Slope area during winter occurred in river systems also used by Dolly Varden, which indicates that juvenile Dolly Varden could be an important source of food for American Dipper in winter.

Offshore Oil Production

The ecological vulnerability of shorelines to oil contamination varies and their self-cleaning ability may be extensive. The ice may restrict the spread of oil. In the biologically active season, oil contamination in this environment will affect an important foodchain. Both the ice and shoreline environments have elements which positively and negatively influence the planning of countermeasures for oil-spills. Offshore oil production in the Arctic is expected to be dependent on enhanced oil recovery (“EOR”). Thus any future environmental impact analyses of the offshore petroleum industry should include this aspect. It is important to analyse the functional aspects of arctic ecology to single out the most vulnerable situations. An oil-spill clean-up plan should avoid vulnerable areas and seasons of the year, and use effective countermeasures in the less sensitive situations.

Warming of the arctic climate is having a substantial impact on the Alaskan North Slope coastal region. The warming is associated with increasing amounts of open water in the arctic seas, rising sea level, and thawing permafrost. Coastal geography and increasing development along the coastline are contributing to increased vulnerability of infrastructure, utilities, and supplies of food and gasoline to storms, flooding, and coastal erosion. Secondary impacts of coastal flooding may include harm to animals and their land or sea habitats, if pollutants are released. Further, Inupiat subsistence harvesting of marine sources of food, offshore resource extraction, and marine transportation may be affected. This paper describes a project to understand, support, and enhance the local decision-making process on the North Slope of Alaska on socioeconomic issues that are influenced by warming, climate variability, and extreme weather events.

Oil Spill Response

The ability to exchange critical information across a broad spectrum of users is the success of a response. Communicating on the North Slope of Alaska is a technical challenge. One of the most critical elements supporting any Contingency Response is telecommunications (telecom). Telecom, as an issue rears its head after almost every exercise or real world response situation. It never seems to matter what type of event the response is supporting, the location of the response or weather that is occurring. Telecom continues to come up as a 'lessons learned'. Recent technological advances (Last 15–20 Years) have resolved some older, yet lingering issues, (e.g. SATCOM, Fiber Optics, Digitization, and the Internet). That said, trying to communicate over an area covering tens-of-thousands of square miles in some of the harshest, most remote regions on the planet is at the very least - demanding. Technically, in many regions, telecom issues can be fairly easy to resolve. In the Arctic, several factors as well as weather play a major part in our ability to respond to an incident. Many areas are not accessible on a road system. Ice roads provide seasonal, temporary access. When ice roads are not available then various aircraft can be utilized. Some sites may only be accessible via specialized vehicles treading lightly on the tundra or that displace the tons of equipment over a broad area for frozen pond, lake and river crossings, minimizing environmental impact. To meet the challenge of Spill Response on the North Slope of Alaska, Alaska Clean Seas and its member companies have developed and employ a network of Very High Frequency (VHF), Ultra-High Frequency (UHF), Cellular, Microwave, and SATellite COMmunications (SATCOM) Systems. A recent Federal Communications Commission directive to reduce bandwidth usage forced the modernization of Alaska's Oil Spill Response Network. The nationwide requirement enables the same number of users to occupy half the frequency spectrum. Alaska is unique in that the entire State's Oil Spill Response Network shares the same frequencies and compatible equipment. This enables the cooperatives to seamlessly support each another. One of the obvious reasons that telecom becomes an issue is non-standardized exchange of ideas, recommendations, or commands. User unfamiliarity with telecom devices (radios, speaker microphones) also contributes to communication barriers. Use of jargon, ten codes and often cultural references can inhibit needed messages from being received as expected. This can easily be improved through Incident Command System training

Oil Spill Response

The Alaska North Slope region is a demanding operating environment for oil exploration, production and transportation operations. The Arctic Ocean remains frozen for an average of nine months of the year, with only a limited open-water season in the summer. There are long periods of darkness, extremely harsh weather conditions, remote installations and limited infrastructure. As Arctic oil exploration, production and transportation activities expand, there is growing concern about the ability of public and private sector response organizations to effectively clean up oil spills under ice. Alaska Clean Seas (ACS) is the Alaska North Slope oil spill response cooperative based in Prudhoe Bay, AK. ACS oversees the training and coordination of the North Slope Spill Response Team (NSSRT), a volunteer-based organization consisting of personnel from the workforce of ACS' Member Companies and their support contractors. Beginning in January 2012, ACS partnered with the U.S. Army Corps of Engineers Cold Regions Research and Engineering Laboratory (CRREL) in Hanover, NH, to develop an Advanced Oil Spill Response in Ice Course. Now in its third year, this partnership has combined the unique facilities, capabilities and ice research history of CRREL with the Arctic response expertise and experience of Alaska Clean Seas to deliver realistic, one-of-a-kind training for recovering oil spilled under ice. Participants have included members of the NSSRT, several federal regulatory agencies and representatives from the Global Response Network. ACS provides response equipment from the North Slope and several vendors have demonstrated additional skimming and pumping systems specifically designed for recovery in ice. Central to the course is CRREL's outdoor saline test basin, a 60′ × 25′ × 7′ refrigerated in-ground tank equipped to grow and maintain a two-foot cover of sea ice. Approximately 600 gallons of Alaska North Slope crude oil are injected under the ice to provide a realistic field scenario to practice response tactics. These tactics include assessment and profiling techniques for safely working on the ice; employing underwater lights and ground penetrating radar for detection of oil under ice; use of augers and chainsaw sleds to cut holes and slots in the ice; deployment of recovery and storage systems to remove oil from an ice environment; and in-situ burning operations in slush and broken ice. This poster highlights the development of the CRREL Training Course and provides guidelines for course content, length, and special considerations for similar advanced field training courses.

The North Slope of Alaska is a demanding and harsh environment. Being prepared for an oil spill involving wildlife in this region requires training, innovation, and partnerships. For the past three years animal care groups, industry oil spill response organizations, and federal agencies have been collaborating to prepare for such an event. Protocol development is an essential and initial process to accomplish response goals. In 2011, protocols were developed for the care of oiled affected phocid seals in Alaska, focusing on the need for remote, deployable operations in the arctic. While developing these protocols, authors drew from their experiences caring for pinnipeds at their facility as well as from involvement in the statewide marine mammal stranding network. As the only institution authorized to rehabilitate stranded marine mammals in Alaska, we are uniquely positioned to assist in mitigating risks associated with possible oil exposure to these animals. Finding resources to treat oiled wildlife is a challenge on the North Slope, especially for medium to long term care. With that in mind, we designed and developed a Mobile Treatment and Rehabilitation Enclosure (MTRE). This deployable enclosure and pool with a life support system meets Animal Welfare Act holding specifications for small pinnipeds including harbor seals, spotted seals, ringed seals, and ribbon seals. The enclosure is designed to be assembled by 2 to 4 individuals and ready for use within 12 hours. While it is purpose built for small pinnipeds it would also be appropriate for short term, triage care of other marine mammals such as walrus calves, polar bear cubs, and sea otters. As a test of our oiled pinniped protocols and the MTRE this system was deployed during the mutual aid drill on the North Slope in August of 2013.

AbstractThe surface condition of the North Water was investigated during two winters (i.e. the three polynyas: Smith Sound polynya, Lady Ann Strait polynya, and Barrow Strait polynya). Since no detailed information was available on ice conditions and the extent of open water during winter, radiometric temperature measurements of the sea surface had to be taken along a flight line of 2650 km from an altitude of 300 m. From November to March 1978-79 and 1980-81, 14 remote-sensing flights were carried out. On the basis of the radiometric measurements, the following ice types were identified: ice-free, dark nilas, light nilas, grey ice, grey-white ice, and white ice. A comparison between the thermal and the visual ice classification (the latter being based on grey tones of the aerial images) showed a deviation of 3%. The analysis showed that in November, December, and January more than 50% of the Smith Sound polynya was covered by young ice, nilas, and ice-free, whereas in February and March white ice was dominant. Moreover, it was found that the two polynyas in Smith Sound and Lady Ann Strait were much smaller than previously believed. In Barrow Strait, a semi-permanent polynya was observed in the winter of 1980-81. The occurrence of polynyas in Barrow Strait seems to be connected with the location of the fast-ice edge. On the basis of the calculated ice-type distribution and heat-flux rates for different ice types, an energy loss of 178 W m-2was found on the surface of the Smith Sound polynya due to open water and thin ice for the winter months November to March. Compared with other ice-covered sea surfaces in the Arctic, the heat release by the sea-water in the Smith Sound polynya is about 100 W m-2larger.

Abstract. The Arctic is warming at an alarming rate, yet the processes that contribute to the enhanced warming are not well understood. Arctic aerosols have been targeted in studies for decades due to their consequential impacts on the energy budget, both directly and indirectly through their ability to modulate cloud microphysics. Even with the breadth of knowledge afforded from these previous studies, aerosols and their effects remain poorly quantified, especially in the rapidly changing Arctic. Additionally, many previous studies involved use of ground-based measurements, and due to the frequent stratified nature of the Arctic atmosphere, brings into question the representativeness of these datasets aloft. Here, we report on airborne observations from the US Department of Energy Atmospheric Radiation Measurement (ARM) program's Fifth Airborne Carbon Measurements (ACME-V) field campaign along the North Slope of Alaska during the summer of 2015. Contrary to previous evidence that the Alaskan Arctic summertime air is relatively pristine, we show how local oil extraction activities, 2015's central Alaskan wildfires, and, to a lesser extent, long-range transport introduce aerosols and trace gases higher in concentration than previously reported in Arctic haze measurements to the North Slope. Although these sources were either episodic or localized, they serve as abundant aerosol sources that have the potential to impact a larger spatial scale after emission.
