Deepwater Horizon Oil Spill - Efforts to protect the coastline and marine environments
The three fundamental strategies for addressing spilled oil were: to contain it on the surface, away from the most sensitive areas, to dilute and disperse it into less sensitive areas, and to remove it from the water. The Deepwater response employed all three strategies, using a variety of techniques. While most of the oil drilled off Louisiana is a lighter crude, the leaking oil was of a heavier blend which contained asphalt-like substances. According to Ed Overton, who heads a federal chemical hazard assessment team for oil spills, this type of oil emulsifies well. Once it becomes emulsified, it no longer evaporates as quickly as regular oil, does not rinse off as easily, cannot be eaten by microbes as easily, and does not burn as well. "That type of mixture essentially removes all the best oil clean-up weapons", Overton said. Deepwater Horizon oil spill WIKI http://en.wikipedia.org/wiki/Deepwater_Horizon_oil_spill

USA Gulf of Mexico - Deepwater Horizon - 20 April 2010
SLIDES – barges – Big Gulp, Little Gulp, A-Whale, MV Arca.
Aerial photos show limitations of booms – only really effective in calm conditions, modest winds,
Not inexpensive ($400/metre), take time to deploy, manual deployment is physically hard, mechanized deployment requires specialized gear, never mind storage space, plus on-site inspection, cleaning and maintenance.
Three new technologies for Oil Removal/Cleanup

The implications for spill response with “Platform-Free Technology” should not be overlooked. If the industry can operate without drill ships and much reduced personnel then they will have a much harder time if things go wrong, since there will be fewer resources in ships and people to deal with incidents. It appears that this is a real possibility for the Arctic.
Lessons learned the Godafoss accident in Feb 2011.
Oil spill recovery at 20oC by Rune Bergstrøm
NOTE – Helicopter (3 minute) flyover of Godafoss incident clearly shows ice conditions

GODAFOSS - Lessons learned
The NCA is still in the process of working with the Godafoss accident. As a result,
evaluation of the overall operation is yet to be done. The list presented here does
not, therefore, provide the overall picture. Nonetheless, it likely gives the most
important findings.
Positive experiences
• Night capacity on oil recovery ships, use of drift buoys, 24 hours/day, made it
possible to follow and collect the oil for almost 4 continuous days.
• Advisors were sent from NCA to local municipalities at the start of the
accident. This helped the get the work on the right track and ensured good
documentation of strategic choices, efforts and costs.
• Sea operations with Norwegian-Swedish cooperation worked well. The use of
different ships’ sizes and equipment gave the necessary flexibility to work in
open sea, in shallow waters and in ice.
• Airplanes, helicopters and drift buoys provided updated and important
information about oil drift.
• Use of large double boom systems with a small opening, followed with a ship
with sweeping arms that collected oil worked well.
• Heating systems in Swedish ships enabled efficient and continued use of the
ships in extreme cold
• Hard working crews in all positions
• No accidents in spite of cold water and iced seashore
Room for improvement
• Not enough knowledge in NCA about the capacity/equipment on Swedish
Coast Guard boats in the initial phase of the operation
• Unloading of oil and containers (explosives) on Godafoss went according to
plan, but the ship drifted before oil recovery systems were on site and ready
(no spill occurred).
• Limitations of booms, pumps etc., in cold weather and collection of heavy fuel
with extreme viscosity.
• Before towing, the outside of the hull should have been inspected and cleaned
(diving dangerous in ice and river current).
• Early warnings to other nations before a ship enters their territorial waters, so
that they could implement necessary to precautions
• Not enough hot water or steam for disconnecting hoses, equipment etc. Many
boats had problems with ice/slush in the cooling system

Discussion and Recommendations (based on this presentation and that of Chris Ives described above)
The image of oil trajectories showing a simulated Gulf of Mexico oil blow out occurring at the same time as the Gulf blowout, but in the Beaufort Sea, are shown below to encourage discussion.
Can anyone clean up an Arctic oil spill?
-
Only demonstrated technologies should be considered and approved for Arctic oil spill response plans and operations and claims by industry as to the effectiveness of particular cleanup methods should be validated by demonstrated experiments in the field
-
Field experiments with actual oil and fuels must be part of the program to validate oil spill response methods and this is especially true in the case of oil in ice covered marine waters and offshore
-
Review of Arctic field testing and actual accidental spill records over the past 40 years indicates that some approaches currently being recommended and adopted by the oil industry and regulators either will not be effective or would have serious and negative consequences on the Arctic environment e.g. in-situ burning, use of dispersants, enhanced bioremediation
-
Field experiments with oil spills should be conducted on a regular basis in order to maintain spill response capability and training levels and to assess new approaches
-
Risk associated with offshore drilling must be minimized by reducing the frequency of major oil spills or blowouts to that of nuclear power reactor accidents i.e. the industry must meet the same standards as the nuclear industry with regard to safety culture
-
Study of the long term impacts of oil exposure including potential chemical dispersants on marine ecosystems should be part of all oil spill field tests (out at least 5 years)
-
Due to the very high cost of Arctic field work, it should be undertaken by international cooperative efforts and funded by a mix of government and industry as in the examples of the Canadian oil spill field projects described in this presentation (the Arctic Council could offer a mechanism for such collaborative work)
-
The use of unmanned underwater vehicles for tracking oil under ice as well as offering an additional method for studying the impacts of oil spills on under ice ecology should be a priority
-
Prior to approving drilling in the offshore regions in the Arctic which are subject to the moving polar pack often containing multiyear ice rather than shorefast ice regime, additional research is required to ensure that methods are found to deal with oil spills in this region of the Arctic marine environment
-
Little consideration has been given to the fact that much of the Arctic basin provides gas and condensates rather than crude oil and as such blowouts and accidents will likely involve these products so preparations for accidents and response methods should target this situation
-
Gas release in the Arctic will result in the formation of gas hydrates causing severe difficulties in working with equipment associated with uncontrolled events during drilling which suggests that additional and on-going research on such blowouts especially with gas and oil releases under ice should be a priority
-
Consider the consequences of a major spill when authorizing drilling permits and include a requirement to model the movement of oil from such sites should a major spill occur since even if the site is acceptable oil released from the site could move hundreds of miles should the spill be uncontrolled for a long period due to Arctic conditions
The majority of oil released is more likely to be caused by shipping accidents, or multiple small spills, than by infrequent major blowouts or shipping accidents. The following recommendations are offered based on a review of some actual Arctic oil spills.
A primary goal should be to avoid/minimise pollution of the Arctic and marine environments
- to give “Mother Nature” a helping hand when and where necessary.
• Respond VERY QUICKLY with resources on hand, to recover any oil / fuels spilt.
Equip, plan and deploy cleanup resources within 1/3 hour, not 72 hours
New skimming technologies enable a fast, effective, and large scale cleanup approach. Such technology still requires more research, development and demonstration in real Arctic spill conditions.
These can be incorporated into suitable existing vessels and barges
Think through the LOGISTICS for major volumes of recovered oil - barges/tankers/tugs/crews/OSV's/bladder tanks
Consider the use of non-oil industry resources to broaden the approaches to oil spill response in light of the financial consequences of making decisions based only on insider considerations. e.g.the banking industry that did not see the recent crises coming
• Avoid the use of burning (severe air pollution) and dispersants (toxic to humans and marine life).
• Use non-toxic coagulants for smaller spills to LOCKUP harmful vapours & toxic components.
Reclaiming of removed hydrocarbon materials is feasible, either as building materials or as solid fuel stocks.
* Strengthen/enhance local SAR capability (SAR = Search and Rescue) that can also contribute to oil spill response requirements
* Clear the decks for fast action - some regulations can hinder the incident commander = Chief Fire Marshall.
Remember the Jones Act? - US could not accept Dutch OSV's for GoM cleanup (labour act precluded non-US bottoms)
Emissions regulation levels effectively require OSV fleet vessels to be stationed 25 miles from the drillship which is not satisfactory for a fast response especially in when ice is present.
• Introduce less polluting energy sources for Arctic shipping eg - low sulfur fuels (follow the lead of the Port Authority of Hong Kong)
- Fuel Emulsification Processes to remove sulphur and reduce emissions.
- LNG versus heavy oils and bunker grades for ship fuel
- Nuclear powered vessels?
