Olympic Class of White Star Steamers
Developed by JP Morgan’s White StarShipping Group Constructed by Harland & Wolff in Belfast included
The Olympic, The Titanic
and
The Britannic
Designed to compete with Cunard & German Shippers on the prestigious Transatlantic English Channel in the early 1900s Built for affluent travelers offering highspeed luxury –
The prized ‘Blue Riband’ was bestowed upon the ship with the fastest crossing. Held by Cunard’s Mauretania 1907-1929

What has changed since 1912
Information technology – Computers, phones, radar Advanced materials – metallurgy, plastics, resins Huge advances in machinery design.
Mass transit systems 11
Timeline
10 April 12:00 departure Titanic from Southampton on maiden voyage to New York (via Cherbourg and Queenstown) 12 April, reports of ice fields on course coming in 14 April, increasing ice field reports, course altered to south, speed maintained at 22 knots 14 April, night: moonless, clam seas, temperatures just below freezing 14 April, 23:00, Californian radioed more ice and mentioned it stopped for the night because of pack ice, answer from Marconi radio operator ”shut up, shut up, I’m busy, I’m working Cape Race” 12
Timeline
14 April, 23:40 – “iceberg directly ahead” alarm from crows nest to bridge – First Officer Murdoch ordered helm hard to starboard and engines stopped – – to prevent stern hitting iceberg, he then ordered helm hard to port, this manoeuvre came too early and ship’s bow hit undersea shelf of ice, causing damage to riveted seams 14 April, 23:52 decision to restart engines by Ismay, increasing leak, with rivets popped open below water line over length of 90 m, allowing increasing amounts of water to enter damaged compartments, causing bow to sink, and water eventually to rise above watertight bulkheads terminating at E deck 13
Timeline
15 April, 00:10 distress calls started (SOS) 15 April, 00:19 engines stopped for last time 15 April, 00:27 first lifeboat lowered (with capacity for 65 people, carrying 27) 15 April, 00:35 distress rockets launched 15 April, 02:20 Titanic sinks 15 April, 04:10 Carpathia arrived on scene 14
What lessons can we (still) learn ??
Learning from previous Incidents Staff Selection Organizational Goals and Leadership Management of Change Material Integrity Emergency Planning 15
The Olympic
– Prelude to Disaster
Learning from Incidents and Staff Selection
21 st Jun 1911
– Upon commissioning crashed into & almost sunk
O.L. Halenbeck
in Manhattan
20 th Sep 1911
- Crashed into the Naval Cruiser the
HMS Hawke
in Southampton
24 th Feb 1912
- Knocked-off one of its twenty-six tone propellers on a well-known wreck in the Grand Banks
Captained by Edward J. Smith
.
Were large displacement effects understood?
How were people trained?

Staff selection and learning from previous incidents
Regarded as very experienced but…..
27 th
Jan 1889 - Ran aground in New York
The Republic
1 st
Dec 1890 - Ran
The Coptic
aground in Rio de Janerio
4 th
Nov 1909 - Ran
The Adriatic
aground outside New York History of running ships too fast through narrow passages.. and of not adequately training his officers
Captain Smith was commissioned to command the Titanic
17
Setting the Right Culture
Titanic was “Unsinkable” and specifically built to “Compete” for the fastest Atlantic crossing – This set the tone for poor decisions and leadership pressures Personnel competency and leadership (pressure to make fast crossing Incident investigation (no culture of near miss reporting and accident / incident investigation on previous events involving captain Smith) Decision by Ismay (White Star Managing Director) to start engines after impact and reach Halifax under own steam) Smith received at least six warnings of Ice from ships at dead stop in the area Titanic sped toward ice field at 22.5 knots vs a recommended 10 knots in such conditions No binoculars in the crows nest made early warning near impossible No need for lifeboats 18
‘Safety outweighing every other
consideration’
Was the framed notice in the chart room of every White Star liner in 1912
19
Setting the right culture
“… I faced a dilemma on the day, standing 20 metres from the explosion and the fire as to whether or not I should activate ESD 1, because I was for some strange reason, worried about the possible impact on production …”
20
Quality Control and Material Identification
Asset integrity (rivets of best rather than best-best quality with high concentration of slags) Shortage of skilled riveters Rivets popping contributed to speed of sinking Inferior quality of steel alloys is a genuine concern today Mix-up of materials is a known cause of incidents – 2nd fire at Texas City 21
Quality Control and Material Identification
France: 6,500 faulty Chinese valves in use N-090925-02 Sud Robinetterie (SRI). Vannes Rigau S.A.S. On September 24, the regional newspaper La Provence reported that it had exclusive information, confirmed by Direction Régionale de l’Environnement, de l’Aménagement et du Logement (DREAL – Regional Administration of Environment, Planning and Housing), that several thousand substandard Chinese-made valves were in use throughout French industry. The valves were reportedly delivered to Vannes Rigau S.A.S., in Lille, on the orders of its parent company in Marseille, Sud Robinetterie. The valves in question were described as “corner or angle valves”, “globe valves”, and “flapper valves”, in carbon steel, and certified by the German TÜV before their entry into France. According to La Provence, the valves have incorrect heat treatment, and are prone to leak at low temperatures. Expected to operate down to 10ºC, they can only be used down to +5ºC. It was alleged that one of these valves may have been involved in an un reported incident at Total’s Gonfreville site in April, 2009 22
Management of Change
Lowering watertight bulkheads to allow ease of movement of people – As the bow sank, water came above E deck, accelerating the sinking as there were no bulkheads to limit the ingress.
– Hazard evaluation (requirement to be unsinkable relies on integrity of watertight compartments, see above) Was the decision to change the rivets a conscious one?
Lifeboats had been reduced for 64 to 22 in favour of more expansive promenade decks cf Olympic design Insufficient to take the passengers and crew 23
Management Of Modifications
As important as ever
Norway's PSA criticizes StatoilHydro's safety culture
In May 2008, StatoilHydro’s Statfjord A platform, discharged 400 m³ of oil from one of the shafts into the Norwegian North Sea. StatoilHydro was forced to evacuate 156 persons.

Management Of Modifications
As important as ever
Norway's PSA criticises StatoilHydro's safety culture
LONDON, September 27 2008
has released a report attacking StatoilHydro's safety standards on the Norwegian continental shelf – Norway’s Petroleum Safety Authority (PSA) PSA indicated dissatisfaction with the quality of the risk assessment StatoilHydro and partners Industrikonsult AS (IK) and Aker Solutions AS carried out for the
modification
work on Statfjord A's utility shaft. It said they had failed to meet regulatory standards PSA issued an order to StatoilHydro to
revamp its procedures
for these types of projects by November 1. It also ordered that
management of modification improvements be appreciably improved by December 1
PSA also ordered Aker
subcontractors" "to identify and implement necessary improvements in the company's management of modification assignments, including identification of risk and use of information about risk in planning and executing hazardous work operations, including the selection of work methods and equipment, and follow-up of
25
Emergency Planning
Major accident potential (worst case scenario sinking) was discounted.
Emergency response arrangements (total lifeboat capacity of 1,172 for maximum number of passengers and crew of 3,547, however complying with regulatory requirements.
– Original design had just about enough lifeboats The officers on board The Titanic had not trained with the lifeboats and were unsure of their holding capacity.
Smith often claimed to have never faced a “near disaster” – Reportedly his performance deteriorated in the last two hours.
Many people could not read the English signs There was not a standing safety response plan.. the ‘Women and Children first’ response was a (commendable) reaction more than a previously-agreed plan.
26
Lack of Emergency Planning – the results
Lives Saved: Lives Lost:
Total passengers Max Lifeboat Capacity 705 1500 2,205 1,600
It wasn’t until 45 minutes after the collision that officers commence preparing the lifeboats Twenty lifeboats were launched Officers feared that the ship’s davits & winches would not hold the weight of the recommended 70 people All but the last few lifeboats floated were half-filled It is a fact that had the Officers filled the lifeboats per their specification an additional 600+ people could have been saved.
27
Does learning have a shelf life?
The lessons from Titanic are still relevant today There are good lessons which cross between industries “Can we learn from the past”….the Risk Engineering team would say yes!
28
Learning From Losses – The Insurance Perspective
Much has been written on learning from incidents – – Almost all clients have incident reporting systems Few formal systems for ‘third party’ incidents Major incidents occur relatively often somewhere – Focus has been mainly on personnel safety – Lessons do not appear to be new Major incidents continue to occur Lessons are well documented, but not always learnt by other organisations – A number of possible reasons for this exist 29
Risk Management and Losses
“Why is learning from losses difficult?”
30
(Not) learning from positive results
Learning from Transformer fires ?
– See plenty of transformers with no dividing fire walls – See plenty of large transformers with no deluge systems 31

So why do we not learn ?
Distance effects Time effects Cultural effects Tunnel vision 35
Distance effects
Local awareness Local media pressure Local regulatory effects Potential differences between multinationals and NOCs 36

Time effects
“Time is a great healer” Loss of experienced people Loss of corporate memory Young companies – Not just in the Middle East Understanding Risk can change with age of plant – “Has worked fine for 20 years” 38
Loss Trends and Analysis Losses by Age of Process Unit (excluding Nat Cat.)
Only includes losses where age of process plant known (sample size of 79 losses) 65% of losses involve process units >30 years old Typical design life 25-30 years
Losses by Age of Process Unit

Source: LIU Loss Database
20 to 30yrs >30yrs 39
Cultural effects
“It has not happened here” Engineers like to believe things work – not consider failure Flawed assumptions re “international standards” Personnel safety vs Process safety Fear of litigation Fear of blame Difficulty in challenging upwards in some cultures 40
Tunnel vision
Within a site Within a division Within a company Within the industry “Unsinkable”, “built to compete” Focus is on projects, rationalisation, expansion, staying afloat 41

FEYZIN 1966 – The Lessons
Design sphere drains / sample points – with fixed valve handles – to discharge outside shadow of sphere – no catch pits under spheres Improved training about: – importance of correct valve sequence and operating procedures – BLEVE can occur with water sprays and open relief valve Improved means and training about raising the alarm Coordination of emergency plans with public authorities to stop public traffic, etc.
Improve fire brigade response times 43
The effect of distance, time, and language ?
Feyzin – French spheres generally good – Japanese spheres poorer – Recent Japanese designed installations below average – Recent survey found plant with most ball-valve handles removed 44
What was learnt from these 2 incidents?

Longford vs. Texas City
Longford Royal Commission Report 1998 “Those who were operating GP1 on 25 Sept 1998
did not have knowledge of the dangers
associated with loss of lean oil flow and
did not take steps necessary to avert those dangers . Nor did those charged with supervision of the operations have the necessary knowledge
and the steps taken by them were inappropriate”.
Texas City Report 2005 Raffinate Splitter Startup Procedures and Application of Skills and Knowledge: “Failure to follow the startup procedure contributed to the loss of process control
. Key individuals (management and operators) displayed lack of applied skills and knowledge and there was a lack of supervisory presence and oversight
during this startup.” 47
Conclusions: how we can learn from mistakes
Recognise barriers of time and distance – Keep the lessons alive Recognise cultural barriers Promote culture of learning – not blame Share positives and negatives Recognise limitations of national and international standards Look at other industries, Columbia 2003, Nimrod 2006 Extract value from your broker relationship .. It’s a great potential knowledge transfer opportunity 48
