Indian Council of World AffairsSapru House, Barakhambha Road New Delhi Issue Brief OFFSHORE ENERGY EXPLORATION: RISKY, YET VITAL Vijay Sakhuja* Nearly two months ago on April 20, 2010, BP’s Deepwater Horizon offshore oil rig suffered an explosion and sank in the Gulf of Mexico killing 11 crew members and 17 injured. The deep-sea well continues to spill oil at a raid rate and a ‘lower marine riser package’ containment cap has been installed to collect oil and gas and transport to the Discoverer Enterprise drillship on the surface where the oil is being collected and the gas flared. BP is mobilising technological resources to capture up to 90 percent of the oil leaking out of the well and plans to drill a relief well to stop the leak completely. Nearly 30,000 personnel, several ships and vessels are responding to the oil spill, and over 17,000 National Guard are being deployed along the coast. This is the worst environmental disaster in the U.S. history, and the U.S. President has issued a six-month moratorium on deepwater drilling. 1 According to some estimates, the Gulf of Mexico spill is more than twice of what was spilled in 1989 into Alaska from the oil tanker Exxon Valdez. The spill response agencies have so far skimmed 475,000 barrels of oil from the surface of the sea and the cost of the operations has exceeded US $1.5 billion, including spill containment, grants, claims and federal costs. The U.S. President has already made four visits to the region and has also raised the issue of liability and urged BP to pay compensation to the victims of the catastrophe. 2 The adversarial impacts of the oil spill in the Gulf of Mexico are quite evident and the ensuing damage to marine life and the eco system is quite visible. Environmentalists and conservationists have argued that continued offshore exploration activities could result in a series of environmental disasters similar to the BP oil spill leading to chaotic scenarios that can potentially heighten tensions among local populace and even states. these rigs and platforms have reinforced materials to withstand hurricanes and storms. Although. Some of these were due to human errors leading to collision between the oil rig . Therefore they present themselves as a very potent target and can be destroyed. These are manned by specialist personnel who are continuously monitoring exploration /production activity. Offshore structures also contain large quantities of materials some of which are highly inflammable and are capable of making lethal mixtures that can produce devastating effect. all experiences. or even exploited by asymmetric actors such as terrorists. Offshore Oil Infrastructure and Accidents Offshore oil infrastructure is a complex web of exploration and drilling rigs. In the past there have several accidents onboard offshore oil drilling /production platforms. it does not require ordinary explosives for an accident to happen and start a fire. The platforms are huge industrial complexes and can be identified at sea from far off distances by the flame that burns atop. these platforms are devoid of robust security systems with few armed personnel to repel an attack by subversive elements. and supply/support vessels. Although these energy complexes are equipped with state of the art firefighting systems but these may be inadequate in the event of a major fire because the personnel operating the platform would have to be evacuated during crisis. it then tabulates the accidents onboard oil rigs. pipelines.” 4 In the backdrop of the BP oil spill in the Gulf of Mexico and the risks in offshore energy exploration industry. The Norwegian Prime Minister Jens Stoltenberg has noted that “We will take into consideration all knowledge. oil spills in the Indian waters and the responses by oil spill containment agencies in India. also the experience from the recent accident in the Gulf of Mexico. they are maintenance intensive and require a very high level of housekeeping particularly to keep them afloat. states and oil companies across the world are seriously engaged in studying the BP oil spill and applying the lessons from the accident. India. I see a very difficult and very challenging time for us to operate within India and outside. The paper also argues for multilateral approaches to fighting oil spills particularly in the Bay of Bengal where Bangladesh. Consequently. Further.” 3 Similarly. production platforms.Meanwhile. incapacitated. this paper argues that it is important for India to examine its offshore exploration strategy by addressing the lessons learnt from the oil spill and also explore multilateral approaches to address issues relating to offshore oil spills. the Oil and Natural Gas Corporation (ONGC) chairman has stated “It (BP oil spill) has been a game changer for the industry…Going forward. The paper begins by highlighting the complexity of offshore oil exploration infrastructure. Myanmar and Sri Lanka are engaged in oil and gas exploration. capable of producing 100. (c) Prevention of marine pollution. The ICG engages in combating oil spill at sea and conducts marine pollution control exercises regularly as also imparting training to interested agencies. on July 27. the Petrobras Platform 36 with a processing capacity of 180. The spill had spread over 8000 sq. these are maintenance intensive and require a very high degree of water tightness. belonging to the Shipping Corporation of India. the accident was a result of ‘deficient procedures and training to deal with emergency situations’ and also due to negligence of not sealing the watertight compartments. the ONGC owned oil platform in the Mumbai High North (MHN) in the Arabian Sea caught fire resulting in a major disruption of domestic crude oil supply. 10 . 9 It is India’s nodal agency in the meetings of the Marine Environment Protection Committee (MEPC) of the International Maritime Organisation (IMO). nautical miles and the slick was observed as close as 10 nautical miles from Nicobar Island. For instance. and (d) Control of marine pollution. Apparently. there were 67 reported incidents of oil spill in Indian waters but in 2008 there were no oil spill reports. In January 1993. The accident occurred when the multipurpose support vessel M/V Samudra Suraksha. drifted. Hurricane Katrina caused extensive damage to another 20 platforms and nine drilling rigs resulting in 90 percent of crude production and 72 percent of natural gas output paralyzed. 6 Natural causes such as hurricanes and typhoons too have resulted in accidents onboard offshore platforms. 8 However. and hit a fuel-laden pipe on the platform causing multiple explosions. In March 2001. The spill was managed efficiently and a major environmental catastrophe was avoided. The force identifies its role through (a) Protection of marine environment. Given the complexity of these platforms. located in the Campos Basin area about 125 km off the coast of Brazil caught fire and sank. The Indian Coast Guard (ICG) is the national agency for ensuring marine environment security in India’s sea areas. 7 Oil Spills in Indian waters and Response Capabilities Between 1982 and 2007. lost control during a medical evacuation. the ICG undertook Operation Safai to control the oil-spill resulting from a collision between two super tankers off the Straits of Malacca. 2005.000 barrels per day.and a vessel. (b) Preservation of marine environment.000 barrels of oil per day. was damaged and 11 persons died and another 11 were reported missing. there were 8 incidents of grounding and sinking of vessels in Indian waters in 2008. In September 2005 Hurricane Rita destroyed 63 platforms and one drilling rig in the Gulf of Mexico and soon thereafter in October. The platform. 5 The fire was so intense that in less than two hours the whole platform warped and fell into the sea. Advance Offshore Patrol Vessel (AOPV) Sagar. 13 India’s Offshore Energy Scene India’s rising demands for energy resources have led to aggressive oil exploration activities at sea to locate new oil and gas fields. is the largest with a capacity of 80. in March 2005. Offshore Patrol Vessel (OPV) Vigraha.000 barrels per day of crude production. the Indian government announced the New Exploration Licensing Policy (NELP) to boost hydrocarbon exploration in the country. An ICG Dornier aircraft reached the site and dropped life rafts. Cauvery basin. India’s EEZ is dotted with offshore platforms engaged in offshore exploration for oil and gas in Cambay/Mumbai basin. 12 The ICG response to the fire that broke out on Mumbai High North (MHN) in the Arabian Sea merits attention.On another occasion. the Indian government opened 164 blocks of which 103 blocks were offshore in deep and shallow waters. The initiative acted as a catalyst and several offshore gas finds were discovered in the deep waters off India’s east coast. Significantly. So far US $9 billion worth of investments have been made under the NELP and production target of 600 million tonne of oil equivalent has been achieved from 203 blocks. The INDSAR and International Safety Net (ISN) were activated by MRCC calling all vessels in the vicinity to render assistance. the ICG responded to a collision between two vessels off Goa on the west coast of India. Mahanadi and West Bengal basins. 14 The NELP VII offered 45 blocks 15 and under NELP VIII 70 blocks around the country were on offer for exploration. In 1998.51 tcf of which 4. The industry response to the NELP was encouraging and so far eight rounds have been announced. Andaman and Nicobar Islands basin. Bangladesh and Myanmar are sitting over a gas lake. 11 The spill was successfully managed in less than four days. 16 Further. Krishna-Godavari basin. Myanmar has . Interceptor boats and Dornier aircraft were deployed to combat the spillage by spraying chemicals through spill spray arm. the Bay of Bengal has emerged as an important source of gas to meet Asian needs.07 tcf have been already produced. Bangladesh has recoverable reserves of 15. the Mumbai High Basin located 160 km west of the Mumbai coast and operated by the ONGC since 1974. and Kerala basin. Kutch basin. Under the NELP VI. It dispatched ships and aircraft to rescue the stranded personnel and also to respond to the oil spill. These ships are equipped with two arms that pump in water and oil inside the ship. Among these. in 2007 the ICG ordered three special vessels from ABG Shipyard. In order to enhance its capacity for combating oil spill. ICG vessels with Pollution Response Equipment and Oil Spill Dispersant were deployed and the damaged vessel was escorted by ICG vessels to Mumbai port. Indonesia.81. turtle nesting areas and other sensitive habitat areas. Any marine pollution related accident would impact on the fragile eco system of the region and would merit immediate response. Malaysia. It could severely impact the fragile marine eco systems and also slow the flow of oil as it .000 square kilometers in the Bay of Bengal. Maldives. it would take a few accidents such as the BP oil spill to bring home the realization of the vulnerability of offshore infrastructure. This issue gains further criticality in the light of the fact that Bay of Bengal is burgeoning with oil and gas exploration activity in Bangladesh. India. 17 Multilateral Approaches to Responding to Oil Spills The South Asia Co-operative Environment Programme (SACEP) to promote the adoption of a Regional Oil and Chemical Marine Pollution Contingency Plan for South Asia has not taken off. there is no institutional mechanism among the Bay of Bengal littorals to address oil spills despite the region being declared as a Large Marine Eco System under the United Nations Environment Programme’s UNEP. marine parks. sanctuaries. the Bay of Bengal is a large enclosed sea with abundance of mangroves. A few days later.03 tcf of natural gas in offshore blocks that stretch over 270. Conclusion From the above discussions. The Andaman & Nicobar Islands in the Bay of Bengal comprise of 572 Islands and are witness to significant merchant traffic. Myanmar. Sri Lanka has offered China and India 9 blocks in the Mannar Basin. a single-hulled tanker carrying 67. on August 13. However. Myanmar and Sri Lanka. the region is also witness to heavy tanker traffic carrying crude oil and gas from the Persian Gulf to the Asia Pacific countries. the Andaman & Nicobar islands are geographically closer to Southeast Asian countries and any response to any oil spill in the region can be best addressed by the eastern littorals. Sri Lanka and Thailand) constitute over 400 million people and are highly dependent on the seas for their livelihoods. Unlike the Arabian Sea. Pakistan decided to obtain assistance from UK to deal with the oil spill instead of India that has national capability to deal effectively with a spill of more than 100 tonnes in sheltered waters. 2003. India. Its littorals (Bangladesh. Although under the purview of the SACEP. corals. the ship broke into two and the resulting oil spill constituted a major environmental disaster. Any damage or degradation of important marine habitats and pollution would impact on their wellbeing. when Tasman Spirit. the question that arises is “Are the offshore oil and gas fields more at risk than people realize?” Apparently.000 tonnes of crude oil ran aground off Karachi port. This is best reflected by an incident on July 27. Besides. 26. January 2009. June 18.cccarto. available at http://www.petrobras. Also needed is a sophisticated warning system to provide total domain awareness of offshore exploration activities and oil spills through a network of surveillance and monitoring. 5 T.
