SAFETY AT SEA<br />

Some 2,300 passengers on<br />

the Jewel of the Seas took<br />

part in the latest Project<br />

Safeguard trials<br />

Order, order!<br />

Spotlight on<br />

evacuation<br />

EU-funded research into passenger responses in an emergency could help<br />

to rewrite the international evacuation rules for cruiseships and ferries…<br />

A<br />

The phenomenal growth<br />

of the passenger shipping<br />

industry over the<br />

past 20 years has been matched<br />

by massive increases in the capacity<br />

of cruiseships and ferries —<br />

in turn generating growing<br />

concerns about safety.<br />

<strong>Nautilus</strong> has been among a<br />

number of organisations highlighting<br />

the potential problems<br />

of evacuating vessels carrying as<br />

many people as a small town and<br />

providing suitable search and<br />

rescue resources — often in<br />

remote areas.<br />

A three-year European Unionfunded<br />

research project — Safeguard<br />

— is now under way in an<br />

attempt to address some of these<br />

concerns. And, as part of this work,<br />

a research team led by the University<br />

of Greenwich recently carried<br />

out what must surely rank as one<br />

of the biggest-ever experiments<br />

in ship evacuation and safety procedures.<br />

The University’s fire safety<br />

engineering group staged what<br />

was described as a unique and historic<br />

trial onboard the 90,090gt<br />

Royal Caribbean vessel Jewel of<br />

the Seas, in which more than<br />

2,300 passengers took part in a<br />

‘live’ assembly drill while at sea.<br />

Passengers’ response times<br />

once the evacuation alarm<br />

sounded were measured by 100<br />

video cameras — which included<br />

CCTV, fish-eye, digital and analogue<br />

cameras — carefully positioned<br />

by the research team.<br />

Passengers also wore specially<br />

developed infra-red tracking tags<br />

throughout the half-hour exercise,<br />

which allowed researchers to<br />

locate each person’s exact movements<br />

and reconstruct the paths<br />

passengers took as they made<br />

their way around the ship to the<br />

various muster points onboard.<br />

Professor Ed Galea, head of the<br />

research team, said the findings<br />

could help to set the benchmark<br />

for future regulation. ‘This assembly<br />

trial was unique in several<br />

aspects, as we collected data from<br />

a large cruiseship, during a virtually<br />

unannounced assembly drill<br />

and while we were actually at sea,’<br />

he explained.<br />

‘The research measured realistic<br />

response times to the alarm, at<br />

a time when 2,300 passengers were<br />

spread over 12 decks. Although<br />

passengers had been told the day<br />

before that we would be doing<br />

a drill, they were largely unprepared<br />

— in their staterooms, in<br />

the bars, in the gym, in the shops,<br />

restaurants and elsewhere — as<br />

the alarm sounded.<br />

‘All of this represents a significant<br />

difference from a typical<br />

assembly trial, which is heavily<br />

announced beforehand, which<br />

takes place before the ship sails,<br />

and where many of the passengers<br />

are already at the assembly<br />

points simply waiting for the drill<br />

to begin.’<br />

The trial onboard Jewel of the<br />

Seas was the third carried out by<br />

the University of Greenwich team.<br />

Two took place last year onboard<br />

a Color Line ferry with 900 passengers<br />

onboard, while two more<br />

will take place early next year<br />

onboard a Minoan Lines ferry that<br />

carries passengers in cabins.<br />

All of the data collected in these<br />

trials will be used to assess how<br />

long it takes passengers to react<br />

to the alarm being sounded and<br />

to start to move to a muster station.<br />

Researchers will also analyse<br />

the way in which they get to muster<br />

points, and the factors that<br />

influence their actions — such as<br />

whether they are in their cabin,<br />

‘When you measure all the<br />

response times for different activities<br />

you get a distribution and we<br />

have found quite significant difference<br />

in response times,’ Prof<br />

Galea said.<br />

The €3.5m Safeguard project is<br />

also using computer simulations<br />

to evaluate the effectiveness of<br />

Nothing on this<br />

”<br />

existing ship evacuation models<br />

and the results should help to<br />

determine whether <strong>International</strong><br />

Maritime Organisation policies<br />

need to be changed.<br />

The project involves partners<br />

from countries including the UK,<br />

France, Norway, Finland, Greece<br />

and Canada. As well as the University<br />

of Greenwich, its members<br />

include the BMT Group, Principia,<br />

Safety at Sea, Bureau Veritas, the<br />

Marine Institute of Canada, Royal<br />

Caribbean <strong>International</strong>, Color<br />

Line and Minoan Lines.<br />

Safeguard builds on earlier<br />

research work — the Fire Exit<br />

project — which demonstrated<br />

that the response time data used<br />

as the basis for the IMO evacuation<br />

analysis protocol was not<br />

rich enough to accurately represent<br />

reality and failed to provide a<br />

suitable basis either for the use of<br />

evacuation simulation programs<br />

or for their validation.<br />

By developing this research<br />

further and obtaining detailed<br />

data on passenger response times<br />

and assembly times, Project<br />

Safeguard aims to result in an<br />

improved new version of the<br />

existing IMO circular, 1238.<br />

Prof Galea said that the scale of<br />

the operation onboard the Jewel<br />

of the Seas was vast. The exercise<br />

required nine months of planning,<br />

while at least six months<br />

will also be needed for frameby-frame<br />

analysis of the video<br />

footage, to measure the reaction<br />

times of passengers as they made<br />

their way to assembly points.<br />

Questionnaires filled in by passengers<br />

onboard at the time of the<br />

drill will also provide extra data<br />

for the researchers to analyse.<br />

The intense preparation paid<br />

off, however, as nearly all passengers<br />

cooperated with the<br />

assembly drill and wore their tags<br />

throughout the exercise. ‘We had<br />

been worried that ship operators<br />

might think we would annoy the<br />

passengers, but what we found<br />

was quite the opposite,’ Prof Galea<br />

told the Telegraph.<br />

‘They were extremely supportive<br />

and quite a lot came up<br />

to us and thanked us for doing it<br />

and looking after their safety,’ he<br />

added. ‘The senior members of<br />

the crew that we dealt with were<br />

also really helpful and behind<br />

what we are doing, and without<br />

their cooperation we could not<br />

have done what we did.’<br />

Tracy Murrell, Royal Caribbean’s<br />

director of maritime safety<br />

and compliance, commented: ‘We<br />

are extremely pleased with the<br />

success of the exercise onboard<br />

Jewel of the Seas. The shipboard<br />

team embraced the spirit of<br />

the exercise and assisted in all<br />

aspects to ensure flawless execution.<br />

Royal Caribbean is proud<br />

to be part of the ongoing efforts<br />

to improve safety onboard passenger<br />

ships and looks forward to<br />

learning from the results of the<br />

project.’<br />

Prof Galea described the<br />

work onboard Jewel of the Seas<br />

as ‘exhausting and exciting’ and<br />

said the results will be far-reaching.<br />

‘The response time data and<br />

the validation data we collected<br />

from the project is truly unique,<br />

and will help set an international<br />

standard for ship-based evacuation<br />

models in the future.<br />

‘Nothing on this scale is likely<br />

to be attempted again,’ he added.<br />

‘The research conducted by the<br />

Safeguard team will help shape<br />

future maritime law and, ultimately,<br />

by informing the design<br />

of better and safer ships, will help<br />

save lives.’
