The Ram Setu Sutra

By

Kanchan Gupta.

 

The Congress-led UPA Government has once again revived the controversial Sethusamudram Ship Channel Project which, if implemented, will cause the destruction of Ram Setu. In 2007 UPA 1 had kicked up a row by contesting the existence of Sri Ram in its affidavit on the issue to the Supreme Court. The uproar of protest forced the Government to withdraw the affidavit and set up a committee of experts headed by environmentalist RK Pachauri. In its report, the Pachauri Committee advised the Government against proceeding with the project.


Curiously, with the next general election looming on the horizon, the Government has once again decided to pursue the project whose cost runs into thousands of crores of rupees. Pushing through big ticket projects on the eve of elections is standard Congress tactics for more than one reason. The Supreme Court should stay the Government's hand and force it to retreat from its hideous decision which can only be termed as anti-Hindu, apart from being disastrous for the ecology of the region. There are several reasons why Ram Setu should be left alone. Here are some of them.


Legend has it, as any Indian child not born of deracinated parents would tell you, that the bridge was built by Hanuman's vanar sena to enable Ram and his army to cross the Palk Strait, march into Lanka, slay Ravan and rescue Sita. For those who believe that the Ramayan is not about Hindu myth-making but an elaborate rendition by Valmiki of what was till then oral history, the building of the bridge was an awesome feat. Images of the vanar sena carrying huge chunks of rock and paving a path across the sea, carved in stone, printed on yellowing oleographs or in Amar Chitra Katha comic strips, inspire both reverence and pride in a past that we tend to belittle. We are, after all, a nation that has no sense of history.


If the stalled Sethusamudram project is revived, dredgers equipped with cutters will resume badgering that past, literally and metaphorically, to create a channel for ships. Before work on the project came to a halt after the Supreme Court's intervention, unwilling to yield without a fight, as if summoning the Herculean strength of Hanuman, the remains of Ram Setu were found to be putting up a stiff resistance and proving to be difficult to be removed. Two state-of-the-art dredgers had to retire injured from the scene of battle.



The Ram Setu Sutra


The assault on Ram Setu is part of the ambitious, Rs 2,427-crore Sethusamudram Ship Channel Project to create a channel for large ships between the Gulf of Mannar and Palk Bay. The channel, if it is ever created, will reduce sailing time for ships moving from India's western seacoast to the east. They have to now circumnavigate around Sri Lanka, which means waste of time and resources. The project has been talked about since the 19th century, but it invariably foundered on the issue of the channel's alignment so as not to get stuck on the hard rock of Ram Setu, or, if you prefer, what British cartographers named Adam's Bridge. It was during the BJP-led NDA regime that the project took form and shape. But before a final view could be taken, the Government fell in the summer of 2004.

The UPA 1 Government's Cabinet Committee on Economic Affairs cleared the project on May 19, 2005. As for the alignment of the channel, the National Environmental Engineering Research Institute's (NEERI's) proposal was accepted. After rejecting alignments proposed by several experts since the 19th century on "technical grounds", NEERI has selected an alignment that runs through Ram Setu, which divides Dhanushkodi/Rameswaram island, travels through Palk Bay, and cuts through Palk Strait, linking the Gulf of Mannar to Bay of Bengal with a deep channel. The alignment runs close to India's maritime boundary with Sri Lanka. The dredged material will be dumped in Indian territorial waters.


» Shifting sandbanks in this area present a far more formidable problem – both at the stage of construction and during maintenance – than the sand dunes on the island site.


» Approaches to a channel would be far too open with no possibility of construction of protective works. A channel at this site – even if it can be made and maintained (which is unlikely) – would entail definite navigational hazard.


» The channel would be bordering on the Sethusamudram Medial Line.


"In these circumstances, we have no doubt whatever that the junction between the two seas should be effected by a Canal; and the idea of cutting a passage in the sea through Adam's Bridge should be abandoned," the report concluded.


Retired marine scientists and experts claim that if the Government persists with the project in its present form, India could be inviting an ecological disaster. They cite the 2004 experience of the coastline protected by Ram Setu escaping the fury of the Boxing Day tsunami.


Destroying the setu, they point out, citing tsunami expert Tad S Murthy, "Opens up serious potential damage to the entire Kerala and Tamil Nadu coast when the next tsunami occurs." The project does not factor in measures to protect the coastline from tsunamis after the existing barrier is destroyed.


Experts have pointed out that as a consequence of dredging and opening of Ram Setu, fragile coral islands will be "destroyed by sediments and turbulent tides of Bay of Bengal entering the tranquil Gulf of Mannar." They have suggested that the channel should be realigned towards Pamban and, like the Panama Canal, locks could be provided at the Palk Bay end and the Gulf of Mannar end to prevent disasters like tsunamis.


Murthy has written to the Prime Minister, suggesting that the alignment be changed northwest-ward to avoid the destruction of Kerala if a tsunami were to hit the southern coastline. "The Sethu Samudram canal has many characteristics similar to the Alberni canal, and this is the reason I am concerned. In the March 28, 1964, Alaska earthquake tsunami, outside of Alaska the largest tsunami amplitude was at the head of the Alberni canal well inland and not at the open coast as everyone expected. Later, I explained this was due to (a phenomenon known as) quarter wave resonance amplification," Murthy explained in his letter.


Experts also aver that thorium deposits in Kerala (Aluva, Chavara) and Tamil Nadu (Manavalakurichi), which have been critical in supporting India's indigenous nuclear programme, "will be desiccated". This could cripple the fast-breeder programme, already threatened by the India-US civil nuclear deal.


But what has led to an emotional upsurge among those who believe that what is under threat is Ram Setu is the manner in which the Congress-led UPA Government has ignored textual and scientific evidence about the structure's historical value. "Damage to Ram Setu is a violation of the Ancient Monuments and Archaeological Sites and Remains Act of 1958 since this is a monument which has remained in existence for over 100 years," one anguished critic points out.


On its part, the Congress appears eager to flaunt its "secular" (read callous towards Hindu sentiments) credentials and insists there are no archaeological studies that reveal the existence of Ram Setu between India and Sri Lanka. Not to be silenced so easily, scholars have dug out a NASA satellite picture that shows the existence of a stretch of rocks in the Palk Strait between the countries. This is claimed as evidence of a bridge having been built once upon a time.


The relevant information, taken from NASA's website, reads: "Shuttle Radar Topography Mission (SRTM) of NASA aboard space shuttle Endeavour launched in February 2000. Sri Lanka is shaped like a giant teardrop falling from the southern tip of the vast Indian sub-continent. It is separated from India by the 50 km wide Palk Strait, although there is a series of stepping-stone coral islets known as Adam's Bridge that almost form a land bridge between the two countries."

Another NASA website entry reads: "Adam's Bridge between India and Ceylon, at the right, is clearly visible. A cloudless region surrounds the entire sub-continent. Differences in colour, green near the west coast, and brown inland, delineate regions of heavy vegetation and semiarid areas." The entries have satellite images attached to them.


As for textual references, there are plenty of them to bolster the case for protecting Ram Setu. Valmiki has described the construction of the setu in vivid terms: Vaanar  having huge bodies, with mighty strength uprooted elephant-sized rocks and mountains and transported them. Ved Vyas refers to Nal Setu or Nal's bridge, "mountain-like, sustained out of respect for Ram's command".


Kalidas has written about how Ram, while returning from Sri Lanka, told Sita, "Behold, Sita, my setu of mountains dividing this frothy ocean is like the milky way dividing the sky into two parts." The Skanda Purana describes the installation of three Shivlings at the end, middle and beginning of the Ram Setu.

It's a heady mix, if you care to listen to those protesting against the project, of faith, science and history. This is not about politics or development, but ancient wisdom being sacrificed at the altar of commercial advantage. Even if you choose to disregard faith based on ancient texts, then look at it this way: Nature's protective cover is being destroyed because the project is a gravy train on which politicians, bureaucrats and contractors want a ride.

Should we allow that to happen?

The Rediff Interview/Captain (retired) H Balakrishnan

'The Sethu Samudram does not make nautical sense'

October 01, 2007

Continuing our series on the Sethu Samudram Shipping Canal Project, Shobha Warrier speaks to Captain (retired) H Balakrishnan of the Indian Navy to know a mariner's view of the project. Captain Balakrishnan has been associated with the navy for 32 years.

He was one of the first batch of three Indian naval officers to do specialisation in anti-submarine warfare in the erstwhile USSR Naval War College.

Out of interest, he did a study on the Sethu Samudram Shipping Canal Project from a mariner's point of view. Ever since the series appeared in the Indian Express, the captain has been much sought after for his interesting calculations.

Why did you get interested in the Sethu Samudram Shipping Canal Project?

I don't belong to any political party. It was purely a mariner's interest that made me research the project. There were many reports and statements in the media but I found that the mariner's point of view was not talked about at all. It is sad that even today the entire discourse on the project has got completely side tracked from the main issue; that is, the project is for ships and the shipping industry.

As a mariner, how do you describe the Sethu Samudram project?

The Sethu Samudram project, if I can put it simply from a mariner's stand point, does not make any nautical sense.

Why do you say so?

I have worked on the project from three different perspectives, all concerning the nautical world. I analysed the project in the backdrop of the environmental factors that would impinge the safety of the ship and also the safety of lives at sea. Number two was the security aspects which is maritime terrorism as it stands today. And the third was certain aspects of general navigation.

What does your research on the environmental factors say?

We mariners call the coast between Rameswaram and Cuddalore the cyclone coast. The India Meteorological Department has assigned this coastline as a high risk probability. To site one example, in 1964, the Pamban Bridge was washed away by a severe cyclonic storm.

A ship is safe when she is moving at the onset of a cyclone. Imagine a ship waiting to pick up its pilot as it approaches the Palk Straits to enter Sethu Samudram. No captain will wait for the pilot; his safety lies in heading south, towards Sri Lanka [Images].

The wind and waves bring in a large amount of silt and wash it ashore. The same thing is going to happen to the Sethu Samudram Canal. This brings me to another point. Marine scientists have identified five areas on the Indian coastline they call high-sinkage pits, and one of them happens to be the Palk Straits.

What is left unsaid by the Sethu Samudram authorities is that maintaining the 12 metre depth (of the channel) will entail round the year dredging. Once you establish the channel, you have to maintain it.

You mean other than the capital expenditure, there will be maintenance expenditure too. Will that be expensive?

Naturally. But this cost is not mentioned anywhere. This is the hidden cost which the authorities will have to pay to the dredging company. It is a high siltation and sedimentation area. So, what you pick up today is going to get filled up the next day.

What is the security threat you spoke about?

The Sea Tigers of the LTTE have control of that area off the Jaffna coast. What the Sea Tigers may do is difficult to say. Piracy exists even today.

Those who are against the project say the 12 metre depth of the Canal is not enough for big ships to pass through the canal. As a mariner, what is your opinion on this?


It is quite true. If you take global shipping trends today, to reduce operating cost, they go in for larger ships of the order of 60,000 deadweight tonnes and above. A 60,000 deadweight tonne carrier will need anything in excess of 17 metres of draft.

And as far as tankers go, the days of the super tanker are gone and you see only very large crude carriers of the type of 150,000 and 185,000 tonnes. It makes more sense to have such big tankers as in one voyage, you are bringing in more cargo and reduce your operating cost.

None of these big ships will ever be able to use the Sethu Samudram. So, the question is, for whom are you building the canal? 30,000 tonnes was alright when Sethu Samudram was conceived in the early fifties and the sixties.

That leaves you with only the coastal bulk carriers that carry coal from Kolkata, Paradeep and Visakhapatanam to Chennai or Tuticorin.

How much time and money are saved if the ships go through the Sethu Samudram Canal instead of going round Sri Lanka?


I plotted physically on a chart what we call 'passage planning' for a bulk carrier on passage as it happens today from Kolkata to Tuticorin; one of them circumnavigating Sri Lanka as is happening today and the other one going through the canal.

The voyage distance from Kolkata to Tuticorin around Sri Lanka works out to 1227 nautical miles. If you went through the canal, it is 1098 nm. So, you are saving just 120 odd nm.

The story doesn't end there. The majority of our bulk carriers go at a speed between 12 and 13 knots. That is the average speed at sea. I have checked with my friends who currently sail. They all said they do 12 knots. However, I worked in a bracket of 12-15 knots. So, if you are going around Sri Lanka at 12 knots at constant speed at sea, the time taken to reach outer anchorage at Tuticorin is 102 hours and 15 minutes.

When you go through Sethu Samudram, the point to be remembered is, you cannot proceed at the speed at which you are sailing at sea. The reason is the shallow water effect or what we call the 'Squat Effect'. So, the moment you enter Sethu Samudram, you have to reduce the sped by 50 per cent or more depending on the conditions prevailing at that particular time. So, I worked on a speed bracket of 6-8 knots. But many of my friends tell me 8 knots is too high for a 30,000 tonne bulk carrier. In all my calculations, I gave the benefit of doubt to the Sethu Samudram project.

The second aspect is, it is not an open seaway; it is like entering a port. A pilot boards the ship, who is a local mariner with greater knowledge of the marine environment. The same thing has to be done at Sethu Samudram also. I have given one hour delay for the ship to reduce speed for the pilot to climb aboard. You repeat the process at the other end too for him to disembark.

With this 6 knots speed and 2 hours pilotage delay, my time to Tuticorin via Sethu Samudram works out to 100 hours 30 minutes. If you went around Sri Lanka, it is 102 hours 15 minutes! So, your net savings in time by going through Sethu Samudram is 1 hour 45 minutes! Is it worth spending Rs 2,400 crore to save 1 hour 45 minutes?

You spoke of travel time. What about the cost?


The Sethu Samudram project from the media reports and the statement given by the finance minister will cost at Rs 2,400 crore, of which Rs 971 crore is through a special purpose vehicle. The debt portion has been pegged at Rs 1,465 crore. Assuming an interest burden of 10 per cent, the interest payment on Rs 1,465 crore is Rs 146 crore per annum. Twenty to 25 years is the time given for repayment.

Assuming 25 years for Rs 1,465 crore, capital repayment works out about 56 crore per annum. So, Rs 146 crore for interest burden and Rs 56 crore as repayment works out to roughly Rs 204 crore per annum which is what the authorities will have to repay to any financial institution. This is only to break-even. But the web site says it is a profitable industry and it is going to make 'mammoth profit'.

As the earning is going to come only from ships, I asked, how many ships are going to transit in a year through the canal? Ships that can use the canal will be coal carrying bulk carriers as long as the Tuticorin thermal power plant exists.

Having made the calculation, I feel they are rather optimistic in their figures. They have given a mean value of about 3,055 ships meant to use the canal in the year 2008 and by the year 2025, they expect it to go to in excess of 7,000 ships. Mind you, for 12 metres of depth! But I can't see more than 1,000 ships using the Sethu Samudram canal in a year.

If you take Rs 204 crore as annual repayment, and 1,000 ships use it, your per ship cost works out to Rs 22 lakhs pilotage charge to break even. There is an interesting comparison done by K S Ramakrishnan, former deputy chairman, Chennai Port Trust. He pegs around Rs 50 lakh as pilotage rate per ship if you have to make a profit.

Then I calculated the fuel consumed. These ships consume 1 metric tonne of fuel per hour, which costs Rs 24,000. For the Sethu Samudram canal, you have to add the pilotage cost too. In effect, if a ship goes through the canal, a shipping company loses Rs 19 lakh per voyage. It is more cost effective to circumnavigate Sri Lanka from the point of view of the shipping industry.

Therefore, neither are you saving time nor is it viable economically. These are the two aspects that need to be highlighted. So, there is absolutely no advantage to the ships and the shipping industry. So, what are we gaining by spending Rs 2,400 crore of tax payers' money? It is a white elephant in the making.

So, you must be against realignment which some political parties are talking about.

Any course, any realignment, is going to prove uneconomical to the shipping industry. If it is of no use to the shipping industry, why build it? You can bring about better economic progress to the southern districts of Tamil Nadu by building expressways. That is why I say the Sethu Samudram shipping canal project makes no nautical sense. That is the tragedy of the project.

Those who support the Sethu Samudram Canal compare it to the Suez Canal and the Panama Canal and say the Sethu Samudram is the Suez of the East.

In the case of the Suez and the Panama canals, ships save thousands of nautical miles in sailing distance and hundreds of hours in sailing time vis-a-vis the Sethu Samudram where a ship will probably save a few hundred miles and at the most twohours in sailing time. This is the difference.
