The Mumbai Oil SpillThere was some good news for the Indian shipping industry as the nation's two premier ports-

Jawaharlal Nehru Port Trust and Mumbai Port Trust-reopened for business partially. Thirty-two ships

had been stranded at the two ports. Most of these carry vegetable oils, steel, crude oil, and naphtha.

Navy ships were pressed into service and escorted small and medium cargo ships in and out of the

canal. Vessels with a draft of less than nine meters will be allowed to use the port during high tide

and under a naval escort. Authorities have stated that it will take at least another week before the

bigger ships can sail through. The Indian Navy's Western Command conducted the operation with

the help of a convoy made up of ships and helicopters. The convoy guided the ships by steering

them clear of floating and submerged containers.The two ports were shut down for five days after

two ships, MSC Chitra and MV Khalija-III, ran into each other off the coast of Mumbai on August 7

and the containers from the former spilled into the sea, leaking oil. Over 300 containers from the

MSC Chitra fell into the water. The Chitra had 1,219 containers on board, of which 31 held

hazardous chemicals and pesticides.The oil slick has spread to a distance of two nautical miles from

the ship. The vessel was carrying 2,662 tons of heavy oil in its various tanks and 245 tons of diesel

oil. Around 800 tons of oil is estimated to have spilled into the sea. The oil spill has hit shippingcompanies the hardest as ship movement to and from the ports of Mumbai and JNPT had been

suspended. These two ports handle 60 percent of India's container traffic.The total number of

containers handled at each of these ports had dwindled to 10-15 percent of their regular capacity. It

was estimated that the trade loss incurred could touch the $4 billion mark if the issue was not

resolved by the weekend. Exporters and importers turned to the government seeking financial relief.

About 33,000-35,000 export boxes are inside the three terminals at the JN Port awaiting the arrival

of vessels for loading while nearly 20 vessels have been diverted to other ports.

Fuel Shortage

With the ports limping back into operation mode, fears of a fuel shortage in the city of Mumbai havebeen quelled. There was a possibility that the city would run out of fuel if the ports did not reopen

soon. Oil and fertilizer ships will be let in on priority.

However, major oil companies such as Oil and Natural Gas Corp. (ONGC), Bharat Petroleum Corp.,

and Hindustan Petroleum Corp.have sought to assuage fears by maintaining that production at their

plants in Mumbai are normal and there is no shortage foreseen whatsoever.

Ecological Impact

The impact is already being felt along the Mumbai coastline, with fish and other marine creatures

being found covered with oil. The oil slick has entered the sensitive mangrove belt and is likely to

damage the environment there. The shores along the green mangroves are coated with slick black

oil. Containers of pesticide are also thought to have spilled over and this is causing alarm to

environmentalists.The government had banned fishing in the region soon after the collision occurred.

The state fisheries department is carrying out random sampling at various locations throughout the

city. The state government has appointed the National Environmental Engineering Research

Institute and Goa-based National Institute of Oceanography to assess the environmental impact of

the accident.

The Energy and Resource Institute (TERI) has volunteered to clean up the oil spill with its

indigenously developed and patented formula of bacteria called as 'Oil Zapper.' The process uses

bacteria to clean-up the oil slick. This might help do away with the effects of the spill.

Cause of the Accident

Preliminary investigations suggest that the accident occurred as a result of communication errors.

An inquiry is being conducted by the Directorate General of Shipping and a report is expected to be

tabled in a month. The captains of the two ships have blamed each other for the mishap. Captain

Laxman Dubey of the Khalija-III alleged that he attempted to establish radio contact with the MSC

Chitra thrice but received no response.Captain M Ranjit Martin, who was at the helm of the Chitra,

said that it was negligence on the part of Captain Dubey that led to the accident. He claimed that the

Khalija-III was not in a good condition after being grounded by Mumbai port authorities earlier in

July. The vessel had been moving into the port when it collided with the Chitra. The Geneva

headquartered Mediterranean Shipping Company, which owns the Chitra, has stood by its captain

on the issue.

Salvage Operation

SMIT Salvage is continuing with operations to clear the containers from the channel. It has cleared

about 60 containers from the sea. The cleanup operation will be tedious and time consuming as it

takes many hours to lift a container by employing metal ropes and a crane. A floating crane and two

tugs have been employed to tow and pick up containers drifting in the channel.SMIT is also pumping

out the remaining fuel from the MSC Chitra to avoid any further spill. Attempts to straighten the ship,

which is dangerously tilted, failed because of the weather conditions. The Chitra is tilted at an angle

of about 75 degrees. Shipping officials estimate that clearing the ill-fated ship could take a few

months.

MUMBAI: Middle Ground Thats the name the Coast Guard has given to the spot where MSC

Chitra collided with MT KhalijiaIII three kilometers off the Mumbai shore on Saturday. On Monday,

when a Hindustan Times team sailed out to the spot, the sea seemed unusually calm as theprecariously listing Chitra swayed with the waves. Miraculously, the containers, stacked high on the

bow that was listing at almost a right angle, werent falling off. It was in an arc about 500 meters

around the vessel where it became clear that the sea was being poisoned by the fuel leaking out of

its tanks. A dark froth was visible as the waves crashed against the hull. Though the slick was not

visible on the surface, the oil was visible on biscuit packets floating away from the Chitra. A

container at the rear of the ship had opened and it was from there that biscuits and chocolates were

floating out. The abandoned ship was completely silent, the only sound coming from the containers

that shifted with every wave. "The ship is perched on a hill right below it said Deepak Koli, a

fisherman who said the fish would not affected by the oil leak. Koli said the 120 containers that had

broken loose were a bigger threat. They could sink fishing boats made of wood. "We heard a

container crashed into a boat, damaging it, he said. Meanwhile several containers with oil traces

reached Uran. Sources said nine containers drifted there, while on was still afloat. "There were large

patches of oil at various spots near Uran. However, the slick has not touched the shore, a Coast

Guard source said. At the Geeta Nagar slum, behind Navy Nagar, Oil washed up with the high tide.

It coated the rocks and even spilled onto the streets with the seawater. Environmentalists said that if

the oil reaches Alibaug it could percolate to the floor of the fragile mangrove patches. The oil could

choke the roots and kill the plants. But scientists said the mangroves were more resilient than

smaller organisms that would get affected. Removing the oil would be difficult if it binds with the

sandy or rocky habitats. Scientists are also worried about the chemicals being sprayed to neutralize

the oil. Deepak Apte, assistant director, Bombay Natural History Society, collected water samples at

Rewas and Mandwa, which had oil. "There should be surveys to check on contamination every two

days, he said. Apte said the flora and fauna in inter tidal areas and shallow waters would be

affected. Oil and toxins will accumulate in smaller fish, which will enter the food chain because large

fish feed on them, said Apte. Apart from the oil affecting marine life, scientists working in fisheries

said oil would obstruct light from penetrating the water. The absence of photosynthesis will affect the

growth of floating plants, said C.S. Purshottaman, head aquatic environment management division,

Central Institute of Fisheries Education, Versova.

WHAT IS AN OIL SPILL?

It is a mass of floating oil covering an area of water, especially oil that has leaked or

discharged from a ship or liquid petroleum hydrocarbon from an oil tanker, Commonly

referred to as marine oil spills and a form of pollution, they include releases of crude oil

from tankers, offshore platforms, drilling rigs and wells, as well as spills of refined

petroleum products gasoline and diesel-and heavier fuels used by large ships, such as

bunker fuel, or the spill of any oily refuse or waste oil.

ON FISH

When oil stops floating on the surface, it starts to sink into the sea. It reduce the

oxygen content in the water and can kill or contaminate fish and smaller organismsimportant to the underwater ecosystem. An oil spill can also take a toll if large numbers

of fish eggs or larvae are exposed to it.

ON MARINE MAMMALS

When mammals such as whales and dolphins swallow oil, it can clog their lungs and

make it difficult for them to breathe. It also disrupts their ability to communicate.

Marine mammals could die of poisoning because they could eat fish exposed to the oil.

ON BIRDS

Birds that swim and dive for food can get their feathers coasted with oil, making itdifficult for them to fly. It also destroys their waterproofing and insulation, thus

exposing them to overheating. If they swallow the oil, it damages their internal organs

and could lead to death. Oil spills can also disrupt migratory patterns by contaminating

areas where migrating birds normally stop. For instance, the Exxon Valdez oil spill in

1989 at Alaska killed 250,000 to 500,000 sea birds.

ON COASTAL MARSHES, MANGROVES, WETLANDS

The plants absorb the oil which chokes their roots and damages the fragile eco-system.

ON WILDLIFE HABITATS AND BREEDING GROUND

Spill can affect nesting and breeding cycles as well as seasonal migrations of various

species.
