4 Root Causes

Medium- 50-5000 bbl./7-700 tons Large > 5000 bbl./700 tons

• Incidence of spills due to internal fires and explosions are less when compared to navigational causes like collisions. 5 Contingency and Emergency Preparedness

Mechanical Chemical Biological Physical Methods Methods Methods Methods

Booms, Manual Dispersants Skimmer methods degrading Bacteria & other biological agents Natural In situ burning processes Gelling agents & explosions biodegradation, oxidation

Currently all these methods are well-developed 6 Response History to Spills • Response methods have not been deployed successfully in many spills. • Response methods aggravated the clean- up operations in Torrey Canyon . • No response techniques due to inaccessibility of the spill area in MT Haven oil spill. • Initial response techniques were hampered by unfavorable weather in Exxon Valdez.

7 Environmental Impact Oil Duration of Location of Characteristics exposure spill

Short term Offshore Quantity effects deep

Long term Onshore Type of oil effects shallow

Amoco Cadiz – largest impact

8 Role of Media on Public Perception and Reputation Losses • Prior 1970, only spills over 100,000 gal captured public attention and spills below 25000 gal went unreported [4]. • Public response not proportional to magnitude of spill. e.g. Exxon Valdez spills and Arthur kill had a significant impact on brand value of the company. • MT Haven and ABT summer spills occurred within a duration of one month. Attention to MT haven was lost after ABT summer occurred. 9 Risk Perception and Public Outrage • Spatial and temporal Local Community factors. • Local community Environmental groups perceive risk differently than experts. General Public • Exxon Valdez- all Government groups actively involved. – Resulted in significant changes.

Responsible • Communities with recent parties catastrophes are more sensitive.

- Objective responsible parties vs subjective public responses. 10

Economic Impact

• Cleanup, loss and damage of materials • Societal Impact -Tourism and recreational activities. • In Exxon Valdez oil spill – 60% loss in tourism business – 35% loss in number of tourist [7] • In Prestige oil spill, – Fishing banned in 90% of the coastline – Tourism affected in Spain and France. • Eco system impact- Fisheries and Mari-culture.

11 Economic Impact Contd.. • Spills closer to shore and affecting human populations are expensive.[5] • Shoreline cleanup to be 4-5 times more expensive than collecting the oil at sea, and 100 times more expensive than pumping oil from the damaged vessel [7].

• EffectAtlantic of Empress spillage rate and amountABT Summerof oil spilled.

12 Regulatory Impact • Post Exxon Valdez, introduction of Oil Pollution Act (OPA) in 1990 [8]. • Office of Emergency Management (OEM) • DOT 49 CFR 110 – Discharge of Oil [9] • EPA led SPAR programs – Spill Prevention And Response [10] • USCG National Contingency Plan • Fire Safety Systems Code

13 Technological & Procedural Changes

2007 2000 Enhanced navigation IMO during introduces 1996 hazards Mandatory Automatic towing Identification 1992 arrangements System (AIS) MARPOL mandates Double hull 1974 SOLAS mandates duplication of essential parts Recent Incidents

9 December 2014, ship collided with 22 March 2014, ship to ship collision cargo vessel Sela river causing leak in Houston ship channel causing leak of furnace oil of intermediate fuel oil

Sunderbans Oil Spill Kirby Barge Oil Spill OT Southern Star Miss Susan- MV Summer Wind 350 ton Collision-550 ton 15 Lessons Learned • Lack of regulatory driver for risk communication covering all target groups. • There is need for study on public perception to improve risk communication. • Community should be involved in emergency planning. • A rapid response using a mix of efficient and effective technologies is critical. • Operations in extreme environments should include detailed assessment to prevent reputation losses and protect brand value. • Increase in competency for preventing oil tanker spills is necessary. 16
