SOLAS amendments on
inert gas systems agreed
Draft amendments to SOLAS to require the installation of inert gas systems on
board new oil and chemical tankers of 8,000 dwt and above, carrying low-fl ashpoint
(below 60°C) cargoes, were agreed by the FP Sub-Committee at its 56th session, for
submission to MSC 92 in June, for approval with a view to subsequent adoption

Ships carrying gas-powered vehicles
Draft SOLAS amendments to add new
requirements for ships carrying, as cargo, vehicles
with engines fuelled by hydrogen and compressed
natural gas were agreed by the Sub-Committee, for
submission to MSC 92 for approval and subsequent
adoption.
The new regulation II-2/20-1 Requirement
for vehicle carriers carrying motor vehicles with
compressed hydrogen or natural gas for their own
propulsion, sets additional requirements for ships with
vehicle and ro-ro spaces intended for the carriage
of motor vehicles with compressed hydrogen or
compressed natural gas in their tanks as fuel.
The requirements include, for new ships: electrical
equipment and wiring of a certifi ed safe type for use
in explosive methane and air mixtures; fans designed
to avoid a possibility of ignition of hydrogen and air
mixtures; and whenever a vehicle carrier carries,
as cargo, one or more motor vehicles with either
compressed hydrogen or compressed natural gas in
their tanks as fuel, at least two portable gas detectors
shall be provided.
Existing vehicle carriers will also be required
to comply with the requirement for portable gas
detectors from the date of entry into force of the
regulation.
The Sub-Committee agreed to further consider
a draft MSC circular on Recommendation on safety
measures for existing ro-ro cargo ships (vehicle
carriers) carrying motor vehicles with compressed
hydrogen or natural gas in their tanks for their own
propulsion at its next session.
Fire resistance of ventilation ducts
The Sub-Committee agreed draft amendments to
SOLAS regulations II-2/3 and II-2/9.7, relating to the
requirements for the fi re resistance of ventilation ducts,
for submission to MSC 92 for approval with a view to
subsequent adoption.
SUB-COMMIttee ON FIRe PROteCtION (FP) | 56th SeSSION | 7 – 11 JANUARY 2013
The draft amendments to SOLAS regulations
II-2/4.5.5 and II 2/16.3.3 will require an inert gas
system to be fi tted on new oil and chemical tankers
of 8,000 dwt and above, when transporting lowfl
ashpoint cargoes (cargoes having a fl ashpoint less
than 60°C). Oil tankers above 20,000 dwt were
already required to install such systems but the new
regulations will lower the required threshold to 8,000
dwt and above.
Related draft amendments to the International
Code for Fire Safety Systems (FSS Code) were also
agreed, resulting in a complete replacement of chapter
15 (Inert gas systems).
The development of the draft amendments follows
intensive work in recent years aimed at preventing
explosions on oil and chemical tankers transporting
low-fl ashpoint cargoes, following recommendations
by an Inter-Industry Working Group (IIWG), which was
established to study incidents of fi res and explosions
on chemical and product tankers.
Additional means of escape from
machinery spaces
The Sub-Committee agreed draft amendments to
SOLAS mandating additional means of escape from
machinery spaces, for submission to MSC 92, for
approval with a view to subsequent adoption.
The draft amendments to regulation II-2/13.4
require two means of escape to be provided from the
main workshop within a machinery space and from
a machinery control room located within a machinery
space. At least one of these escape routes shall
provide a continuous fi re shelter to a safe position
outside the machinery space.
All inclined ladders/stairways with open treads in
machinery spaces being part of or providing access
to escape routes are to be fi tted with steel shields
attached to their undersides, to provide escaping
personnel protection against heat and fl ame from
beneath.
