Piper Alpha and Titanic – Safety lessons for Oil & Gas Industry
By Captain Chandra Godakanda Arachchi
Master Mariner, Gladstone LNG Australia
S. S. Titanic was said to be unsinkable. Similarly the oil platform, Piper Alpha, owned by Occidental Petroleum, 110 miles from the Port of Aberdeen, operated in extreme weather conditions for most part of the year and, therefore, was considered indestructible. The sheer size of the structure also contributed to this view. The sinking of Titanic has been the maritime disaster of all time and the Piper Alpha disaster where 70 percent of the 226-member crew on board, in the North Sea, is said to be the worst off-shore oil platform tragedy of all time. A series of explosions caused some sections of 300-foot tall structure to collapse within three hours. It became a flaming ball of twisted metal.
Piper Alpha was producing 30,000 tonnes of oil per day, 10 percent of the British North Sea oil production. The shipping industry witnessed an unprecedented regulatory regime post the grounding of Exxon Valdez, in Alaska, in 1989, causing a massive crude oil spill; similarly Piper Alpha disaster led to the introduction of significant regulatory changes in the oil and gas industry in terms of safety improvement and managing “Permit to work” system.
Piper Alpha, which operated 12 years from 1976, was first built for oil production but modified for gas production as well. Piper Alpha was connected to a network of oil platforms (Claymore and Tartan).
Almost all survivors from Piper Alpha were those who jumped into the burning sea from a height about three hundred feet which required a lot of courage.
What really happed on 06th July 1988. Here is the story in brief!
It was just another summer night in North Sea, 06 July, 1988. Some 226 crew on board Piper Alpha were having another night shift with usual problems the control room had to deal with.
Piper Alpha had two gas pumps (centrifugal compressors), A & B, to boost gas pressure for delivering gas to Flotta, an island terminal off Scotland. There had been two work permits issued during the day shift, one for pressure safety valve (PSV) servicing and the other for overhauling compressor A; the work would have taken two weeks. The crew had removed the PSV for servicing and taken compressor A out of service only by isolating power, which is illegal. The industry now requires full isolation, key common lockout by workers, permit holder and permit authority so that everyone involved in work has to unlock before being able to start the compressor. Crew could not complete servicing PSV as expected by 1800 hrs and the engineers decided to postpone reinstating the PSV until morning and fitted a blind flange (metal plate) where the PSV had been removed. (It was probably not a pressure rated flange). The overhauling of the compressor A had not begun during the day shift, and this was noted in the work permit form. When the engineer concerned arrived in the control room to hand over the permits, the supervisor was busy and therefore he failed to inform the latter that the PSV was out of service. He, however, made notes on the permit form, returned two permits and knocked off for the day. Unfortunately, two permits got separated in the control room. There could have been many permits on that day due to a new gas line being installed during weeks. Piper Alpha was not shut down for gas line installation as the installation could be managed with control measures as stipulated. A critical aspect to note here is that nobody in the control room had an update of incomplete PSV work. In the mean time, the diesel fire-fighting pumps had been switched to ‘manual from ‘auto’ as a control measure to prevent divers who were at work being sucked in case the fire pumps started in ‘auto’ mode.
At 2145 hrs, the compressor B tripped and failed to restart despite repeated attempts by the control room. Now, there was another risk looming due to tripping the compressor. In case of failure to get the compressor started within a certain period of time, the platform runs the risk of losing gas pressure, which is required to run the gas generator. The consequence of shutting down the gas generator is huge with platform shutting down including drilling. There is also the likelihood of the drill head getting stuck. Getting everything back online is a time consuming and that involves a huge cost. Therefore with this scenario in mind, the shift engineer traced the permit for compressor A and noticed that overhaul work had not begun but failed to realise PSV was out of service due to the unfortunate separation of permits. At 2155 hrs, the supervisor assumed it was safe to start the compressor A and ordered reinstating power and got it online. As the PSV was located about five metres above the compressor, the crew failed to notice the missing PSV. As the compressor started at 2157 hrs due to the sudden rise in pressure, gas started to leak from the temporary blind flange. A huge amount of gas leaked and alarms were going off in the control room continuously; this was followed by an explosion. The supervisor immediately activated the emergency shutdown (ESD), which shut off safety valves (XVs) of the huge oil and gas production risers of Piper Alpha from sea bed, isolating Piper Alpha, but it appears that it did not shut down the connections to other network oil platforms. The explosion did rupture the fire walls in oil separator area, which caused an oil fire to erupt.
It was believed that at 2204 hrs only two crew members had been killed due to the blast. There had been similar fires in certain other rigs but they had been doused. When the fire started, fire fighting pumps should have started, but unfortunately pumps had been switched to ‘manual’ as was said previously. Two brave members tried to and start the pumps manually, but they failed and were never seen again. At this stage, emergency procedures simply collapsed and the Rig Manager who was supposed to coordinate the emergency from radio room sent a distress message, which was heard by the two nearby rigs, Claymore and Tartan. No attempt was made to announce the distress message over the public address system. No one told the crew what to do. Workers were supposed to gather at life boat deck and wait for instructions in case of emergency, but the fire prevented them from reaching the muster point and, therefore over 100 crew members waited in fireproof accommodation block beneath the helicopter pad and waited for helicopter rescue. However, the wind was blowing the heavy smoke over the helicopter pad and it was impossible for the helicopter to land. Accommodation block too gradually started to fill with smoke and even at this there was no attempt whatsoever to evacuate the crew to safety.
ESD had shut down oil and gas production, but oil in the separator continued to burn, and it eventually burnt itself out with the fire extinguishing itself, but Claymore continued to pump oil even though Claymore heard the May Day, and witnessed the flames of Piper Alpha from a distance. It was waiting instruction from on shore Occidental control room to shut down. Claymore repeatedly attempted to contact the shore control room for a long time but without success. Therefore the discharge pressure of Claymore and Tartan oil pumping fed oil through a damaged pipework to fire on Piper Alpha, adding more and more fuel to fire. Both Claymore and Tartan knew it was costly to restart the production from platform post ESD, and that perhaps led them to wait for instructions to shut down rather than taking decisions on their own.
There was another huge problem looming at 2218 hrs with oil fire heating the high pressure gas risers (on Piper Alpha) from Titan. Heat eventually damaged the pipe work of high pressure gas riser from Tartan, adding three tonnes of gas per second to already burning Piper Alpha. Most crew members were still alive. Some of them decided to jump into the burning sea from a ten-storey-high Piper Alpha prior to the second explosion. Those are the people who survived and 167 crew members were killed. More than 75% of the Piper Alpha facility was destroyed although it had been considered indestructible. Emergency response vessel Faros by luck happened to be there anchored closer to Piper Alpha. It attempted to start the fire pumps in a hurry, causing them to trip and this led to a 10-minute delay in operating them. The extendable gangway was unusually extremely slow and it took more than an hour to reach the deck with crew. It was too late. After the second explosion, Faros could not get closer to Piper Alpha due to intense heat and it manoeuvred away from Piper Alpha for its own safety.
Occidental Petroleum later destroyed the remains of Piper Alpha within a year, closed down the operation never to operate in the North Sea ever again. Investigators found that the safety culture on Piper Alpha had been superficial. CEO of Occidental Petroleum at a post-disaster press conference said that 06 July 06 was the first incident in twelve years since the commencement of operations, but the fact remains that a crew member had been killed in an accident four year prior to the Piper Alpha tragedy. That could have been an ideal opportunity for the company to review safety procedures on Piper Alpha. Had Occidental Petroleum been seriously committed to safety, the incident probably would not have occurred and 167 crew would not have been killed.
It is extremely important to comply with safety standards in oil and gas industry.

Are rice consumers and farmers victims of current practices?
by Neville Ladduwahetty
One of the subjects President Anura Kumara Dissanayake is responsible for is agriculture. On the other hand, subjects such as food security and health that are related and dependent on agriculture come under the purview of Prime Minister Harini Amarasuriya. Consequently, the production and distribution of agricultural products have a bearing on access to food at affordable prices to ensure not only food security but also on poverty and malnutrition. Thus, responsibility for the welfare and wellbeing of the majority of Sri Lankans depend on the joint efforts of the President and the Prime Minister.
An area that will have a significant bearing on the above is the production and distribution of rice. This topic is addressed in a well-researched article titled “RICE MONOPOLY Continues to Put Farmers and Consumers in Peril” by Prageeth Sampath Karunathilaka (Daily Mirror, Sept 25. 2024). This article confirms that consumers and farmers are victimised not only due to shortages in production but also by the current practices that are permitted to operate with regard to the production and distribution of rice.
RICE PRODUCTION
The aforesaid article says the per capita rice consumption is approximately 125 kg per year. Furthermore, it states that during a conversation the author had with a former Director of Agriculture, K.B. Gunaratne, he had commented that despite the fact that there were variations during COVID, Sri Lanka must produce an additional 2.4 million metric tons annually”.
The argument that Sri Lanka is self-sufficient in rice does not hold water. Therefore, since the current shortfalls have a bearing on market prices which in turn have a bearing on health, poverty and malnutrition, price variations should be avoided. It is therefore imperative that rice production be increased and stocks monitored regularly to ensure that sufficient stocks are available at any time because shortfalls are often the cause to justify increasing market prices.
Increasing paddy production could be achieved either by advanced technologies or by bringing more land under cultivation. Since the latter approach would involve an increase in infrastructure and maintenance costs, it would be more prudent to resort to advanced technologies because human capital and related infrastructure are already available. Furthermore, the former approach is likely to bear not only faster results but also more income to the farmer through increased yields.
CURRENT PRACTICES
The article cited above states: “In the past large-scale paddy mill owners sold rice at Rs. 220 per kilogram, based on the government’s guaranteed price. Meanwhile, smaller mill owners sold the same rice for Rs. 160-175 per kilogram. This allowed large scale mill owners to make a profit of Rs. 60-75 per kilogram of rice. They earned significant profits from paddy purchased at low prices. Although the government set a guaranteed price of Rs. 100 per kilogram of paddy, some large-scale mill owners bought it for as low as Rs. 70-80. It is no secret that purchasing hundreds of thousands of kilos of paddy at low prices and storing it led to massive profits ….
According to the National Institute of Post-Harvest Management, a large-scale mill owner earns at least 4 million in profit per day, which amounts to Rs. 120 million per month … To produce one kilogram of Nadu rice, about 1.5 kilograms of paddy are required”. This is so with other varieties as well. Thus, on average, nearly 2/3 of rice is produced from 1 kilogram of paddy.
“The cost of producing one kilogram of rice, including expenses such as machinery, electricity, labour and distribution is approximately 25 rupees. Given the government’s guaranteed price of 100 rupees per kilogram of paddy, rice can be sold to consumers at 160-175 rupees per kilogram. However, in the current market, a kilogram of rice is sold at 220 rupees”.
With due respect, there appears to be an inaccuracy in the conclusion that “rice can be sold to consumers at 160-175 rupees per kilo”. If as stated in the article cited above, 1.5 kilos of paddy are required to produce 1 kilo of rice and the guaranteed price is Rs. 100 for a kilo of paddy, it means a farmer would need Rs. 150 to produce 1 kilo of rice. To this, if Rs. 25 is added as the cost of production as stated in the article, the bare cost without profit would be Rs. 175. Therefore, the comment that “rice can be sold to the consumer at 160-175 rupees per kilogram” needs to be revisited.
STRATEGY for the IMMEDIATE
What is evident from the foregoing is that the higher the guaranteed price for paddy, the greater is the benefit to the farmer because of increased income. On the other hand, high guaranteed prices for paddy results in high prices for the consumer. What is demonstrated above is that with a guaranteed price of Rs. 100 for paddy, the price to the consumer has to be close to Rs. 200 and above. Another fact demonstrated is that a high guaranteed price to the Farmer and an affordable price to the consumer is an incompatible proposition. Consequently, the challenge is how the farmer could earn a worthwhile income while ensuring that the consumer has access to rice at an affordable price.
A fact that influences this challenge is the availability of paddy surpluses soon after each harvest. The large-scale millers have financial capacities and infrastructural resources to buy large stocks following each harvest at low prices and store the paddy. Consequently, farmers are at their mercy. Such advantages are not available to small and medium scale Mill owners. However, the Agriculture Department reports that it is “set to provide a maximum loan amount of Rs. 50 million rupees for small and medium scale rice mill owners and maximum loan amount of Rs. 25 million rupees for paddy storers and collectors through state and private banks…” (Dept. of Agriculture Report).
An alternative proposed by All Ceylon Farmers’ Federation (ACFF) Convener Namal Karunaratne speaking to The Sunday Morning (June 25, 2023) is “that prices could be reduced if production cost was reduced… For instance, to reduce production costs, farmers’ equipment and gear need to be freed from taxes. Fertiliser prices need to be reduced. If production costs are reduced to about Rs. 60 a kilo of paddy can be sold for Rs. 80-90. The responsibility for this is in the hands of the government.”
Similar concepts have been in operation since 2000 by The Farm Storage Facility Loan Program (FSFL) of the US Department of Agriculture. FSFL provides low-interest financing so producers can build or upgrade permanent and portable storage facilities and equipment. Eligible commodities include grains, oilseeds, peanuts, pulse crops, hay, hemp, honey, renewable biomass commodities, fruits and vegetables, floriculture, hops, maple sap, maple syrup, milk, cheese, yogurt, butter, eggs, meat/poultry (unprocessed), rye and aquaculture. Eligible facility types include grain bins, hay barns, bulk tanks, and facilities for cold storage.
Drying and handling and storage equipment is also eligible, including storage and handling trucks. Eligible facilities and equipment may be new or used, permanently affixed or portable. Since its inception in May 2000, more than 33,000 loans have been issued for on-farm storage, increasing storage capacity by 900 million bushels.
FSFL is an excellent financing programme for on-farm storage and handling for small and mid-sized farms, and for new farmers. Loan terms vary from 3 to 12 years. The maximum loan amount for storage facilities is $500,000. The maximum loan amount for storage and handling trucks is $100,000. In 2016 FSA introduced a new loan category, the microloan, for loans with an aggregate balance up to $50,000. Microloans offer a 5 percent down-payment requirement, compared to a 15 percent down-payment for a regular FSFL, and waive the regular three-year production history requirement.
CONCLUSION
The clear objective of any government has been to ensure a healthy income to the paddy farmer and rice at an affordable price to the Consumer. Achieving such an objective means improving the welfare and wellbeing of nearly a third of the population who are engaged in production and improving the health of the whole nation with an impact on poverty.
A variety of opinions and proposals have been expressed and explored over the years to realize the objective stated above. Most of them involve the intervention of the Government in one way or another. For instance, one way is for the Government to control 10% of paddy production to stabilize production and to provide financial benefits in one form or another to reduce costs.
One form of financial assistance considered has been to provide loans to establish small and medium scale Mills and storage facilities throughout the country; a strategy adopted by the US Department of Agriculture. Another form has been to subsidize fertilizer and other inputs required in the production of paddy. Yet another is to establish guaranteed prices for paddy; a strategy that favours the Farmer but not the Consumer, as stated above.
None of these options have proved satisfactory, as far as achieving the desired objectives are concerned. The reason perhaps is because strategies proposed are from the perspectives of the Farmer or the Consumer and not from a holistic perspective of both. Therefore, the strong recommendation is that a Forensic Audit is conducted to ascertain the most effective strategy or strategies to meet the interests of both Farmer and Consumer.
However, what is needed in the immediate term is for the Government to engage with the large-scale mill owners and the representatives of the All Ceylon Farmers’ Federation to establish a sustainable compromise arrangement that serves the interests of both the Farmer and Consumer because at the end of the day, their interests affect the wellbeing, health and food security of the whole nation, the responsibility for which rests jointly with the President and the Prime Minister.

Hope for future; Heads need be cautious
Many good things have been happening; the best is that in all Sri Lankans, barring opposing political parties and politicians, hope has been rekindled after decades of gloom and doom. We trust, admire and have full confidence in the President and the Prime Minister. Cass does not need to spell these out and give reasons.
Beware the bullet
Open letters have been penned and seen in the public sphere as how things should be done. Personally, Cass believes no pontificating nor even advice is needed. President Anura Kumara Dissanayake and his advisors, and Dr Harini Amarasuriya know what they have to do, how best to do these, and they will deliver, for the greater benefit of the country and its people. Already things are greatly improved like food items getting cheaper.
Cass always wondered why eggs and onions were imported from India, Bangladesh and Pakistan when we can produce our own, and if there occurred a shortfall, we just had to tide over that hiccup and use less or no eggs and onion. Then she was told of the import mafias – unscrupulous persons making personal profits at the expense of the country and us The People. The authorities, under the new dispensation which is honest and wise and true to the country will stop import of inessentials. That will give a boost to local producers. So, enjoy it!!
One matter Cass wanted to write an open letter to the two Heads was to please be careful; employ high security; cut down on moving around freely. They have to be very cautious. The entire country’s future now depends on these two: the Prez and PM. This is no exaggeration. Murderers, willing now to kill for perhaps a mere Rs 2,000, float around looking for their kind of work. Someone corrected Cass when she said this. Stupid, a murderer can be hired for a shot of arrack, so low is the morale of some and so rampant are sharpshooters ready to be hired.
The two Big Ones must constantly keep in mind that there are politicians in kapati suits who do not have an ounce, nay, an atom of conscience. The hunger for power, envy, need to avenge being defeated are so great that for the sake of just himself, he will order the murder of someone, even though it will shatter the entire country and send it plunging down a gorge worse than the bankruptcy they caused. Also, a strong motive pushes them forward to order a killing – their being open to exposure now that previous crimes are to be re-investigated, and more closely.
Remember Lasantha W was brutally, horrendously murdered just because he was writing about an act of suspected corruption. Even more tragic was the torture and murder of ruggerite Wassim Thajudeen since he cocked a snook at powerful sons and was, it is said, due to a dispute about a sports team. Those who were suspected of commissioning the murders and the murderers themselves are still free and around. Nothing was proven in these cases so what Cass says here is almost hearsay, but fingers pointed then and still do so. Murder simply cannot be overlooked.
Advice given by elders when we complained of a theft of something of ours was: Why do you accommodate temptation? Why are you not careful about your possessions? Do not keep them lying around, inviting theft. Now that Cass is the older person and allowed to advise: please, increase the security around our Head of State and Head of Government. It was wonderful seeing the President Elect let himself out of his car and walk unescorted by security personnel to take his oaths as Head of State. He needs to change his stance; and Harini as well. They need very secure, foolproof protection. They must also cut out walk-abouts.
Work ethic
Iridescent, luminous is the message conveyed by the true story of the son who reported for work in the skies while his father was taking oaths as the Prez of the Democratic Socialist Republic of Sri Lanka. His reply to his peers who asked him why he was not among the VVIPs at this momentous event is said to have been: “I let my father do his job and I like to do my job.”
That ethos was much with us older persons when we were in careers: hardly took leave, especially medical staff and teachers, (not government teachers who were often non-caring of kids in their charge); we worked a full day. Cass remembers going to her place of work the day after her husband was cremated. Shocked looks. You could have taken a week off. But why? I did all I had to do and now I am ready to carry on my job. She remembers as the Education Officer in a professional association finding students taking very long over an assignment they had to submit before final results. Why have you taken so long to complete the research and submit your paper? My father died? When? A year ago. So, you are in deep mourning all this time, unable to do what you have to do! That is the general trend in this lotus eating country of ours.
Back to work
This malaise has ceased. Goodness gracious! A woman reports that she visited the income tax office in the past week. A department which had earned the wrath of the public for sending them from pillar to post. But to her utter surprise and delight her work was attended to, pronto, and she was treated politely.
Cass had a report to get about a piece of land. Her agent went a number of times to two offices concerned and spent many hours, but the document was not signed. The person authorised to sign the document had gone to political meetings, he said. The agent told her the officer expected jarava – oiling palms. Post September 23, Cass told her agent that now he would get the completed document handed over to him the moment he went in!
Demise of the vehicle parades
A vendor on Thurstan Road opposite Royal and Thurstan Colleges told a friend that normally a large number of armed forces’ vehicles driven by uniformed personnel would stop in front of where he was to drop boys studying at Royal. But no longer since September 23!
Monday late news reported that 107 vehicles, all luxury, were allocated to Presidential advisors, secretaries et al by ex Prez Ranil W. So very many advisors when he was a man who decided matters often on his own? What did Rosy Senanayake advise him on, pray? Sartorial elegance? This is just one institution and the cost borne by us, citizens, in maintaining them a favoured bod could cruise all over in a public paid for vehicle? Deeply shocking!
Dr Harini Amerasuriya’s views
Cass listened to an interview conducted before the presidential elections by Kishani Alanki of Conversations with Dr Harini Amarasuriya where she was asked what she stood for if the NPP won the presidency. Cass’ heart got lighter, hopes kept rising and pride was born within as Dr H A outlined strategies she would promote. She first made clear the ideology of the NPP and its inception – the National People’s Power or Jathika Jana Balawegaya, established in 2019, is a socialist political alliance led by the Janatha Vimukthi Peramuna, consisting of 21 political parties.
Dr H A’s main areas of interest are education, women’s and children’s concerns and of course bringing equality among all in the island, particularly concentrating on erasing the divide between the haves and the marginalized. She was questioned about the low representation of women in Parliament and how she fared, with the majority of her co-MPs being male. She smiled broadly! She said she fared well but there were instances when behaviour toward other women MPs was below par (Cass’ words).
Encouraging it was to hear that in her interaction with women in various spheres of employment and economic status, she found so many willing to give of their ability to improve the condition of the people of the land. Yes, Cass agrees wholesale with the move: give a woman a job and she will do it well, with full commitment and effort. Corruption and its temptation are so much less in women, Cass boldly affirms.
So, unlike on previous Fridays, with Cass’ dismal mood infusing her Cry with acid and suppressed frustration, she now looks to the future with hope and enthusiasm.
