Conclusions

RINA initiatives

RO-RO passenger ships have suffered some significant accidents

Internal investigation on our fleet (over 300 ships; 3.8 million GT;

23% of market share in RO-RO pax and ferries)

Focus on ships fitted with open RO-RO spaces

Identification of voluntary services to reduce the possible re-

occurrence of incidents

Marine Asset Integrity Management

Conclusions

Open RO-ROspace concept

Open RO-RO space: introduced for the first time in 1981 amendments

of SOLAS 74, which entered into force in September 1984

Carriage of dangerous goods: safety requirements introduced for the

first time in the same amendments (Reg. II-2/54)

For a given dangerous goods, safety requirements are less strict if

carried in an open RO-RO space

Open RO-RO spaces do not favor the formation of clouds of

flammable and toxic vapour

Effects of the wind on the performance of the fixed pressure water

spraying systems

Impossibility to seal the space in case of fire

The minimum requirement is that only a portion of the entire space

(and not the whole space, as in the case of CO2 for the engine room)

is covered when the water spraying system is activated

As a consequence, the fire-fighting capacity depends on the prompt

and correct detection of the areas affected by the fire

They are not connected with the emergency source of electrical

power

The different performance of heat, smoke and flame detectors in

the proximity of side openings

Fire protection

Life-saving appliances

Protection of life-saving appliances, due to the presence of side

openings

“A-60” standard: average and maximum temperature of 140°C and

180°C respectively for the unexposed surface

High temperatures may reduce the efficient use of adjacent spaces

(bulkheads facing life-saving appliances stowage areas, muster

stations, escape routes, life-rafts lowering stations, etc.)

After one hour the fire may go out of control and abandon ship

operations impaired

Electrical Installations

All parts of the electrical system downstream the last ship’s

protection suitable for the maximum protected current

Portable cable sectional area sufficient to carry the maximum

protected current

Users’ voltage, frequency and power

Maintenance of portable cables, plugs and sockets

What is AIM?

An AIM concept has to address all

aspects of business that can

impact personnel, environment,

process, safety and system

reliability to secure the

economical base of the asset

owner

AIM mainly relies on the

management of physical assets

Recent tragic episodes have highlighted the importance of assessing

the consequence of the loss of one space and, obviously, of all

Hot spot assessment in machinery spaces

Ro-ro space electrical equipment surveys

Maintenance of public and technical spaces

Fire risk mitigationEnhanced Inspection Scheme

The human factor is always a key factor and the crew is essential for

the operation and management of the ship in the normal and

emergency conditions

Investment in personnel training is a strategic option which has

tangible benefits in terms of:

technical performance

commitment to excellence

attracting the right people

Risk associated with Human Factor

Specialistic technical training should be supplemented by specific

courses for ro-ro operators centered on the management of stress,

emergency and crisis

Leadership on the bridge

Communication: written, public, direct

Inter-functionality - Conflicts management

Teamwork

Conclusions

Conclusions

The Industry shall develop guidelines and best practices aiming at

minimizing the risk of re-occurrence of fatal accidents

Reference should be made also to techniques which are very well

known and widely used in the offshore and nuclear industry

The Industry shall promote an increased safety culture and play a

proactive role in identifying areas where the current international

regulatory framework could be revised and improved
