FIRESAFE II Containment and Evacuation
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Fire and smoke containment are well known issues during fires in ro-ro spaces, especially in case of uncontrolled fires. Similarly, in some accidents, evacuation systems remained inoperative due to the heat and flames coming through the openings of the ro-ro spaces.This report presents a Formal Safety Assessment on containment and on evacuation following a ro-ro space fire incident on any ro-ro passenger ship.The safety level was estimated for three generic ships representing the world fleet of RoPax ships (Cargo, Standard and Ferry RoPax) and a cost-effectiveness assessment was performed on three Risk Control Options (RCOs), taking into account potential differences between newbuildings and existing ships.From a containment perspective, the RCO Fire monitors on weather decks was found cost-effective for newbuildings and existing ships of the three ship categories.From an evacuation outlook, a safe distance was estimated to ensure the protection of stowage areas, embarkation stations and evacuation routes, and LSA failure due to heat and smoke following a fire in a ro-ro space. Several design solutions were investigated and cost-effective solutions were found for the Standard RoPax and Ferry RoPax.

FIRESAFE II Detection and Decision
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Early detection of fire and quick activation of the fire extinguishing system are often considered as the main keys to successful fire management, allowing to prevent loss of life and damage to the ship and cargo.This report presents a Formal Safety Assessment on detection and on decision of extinguishing system activation following a ro-ro space fire incident on any ro-ro passenger ship.The safety level was estimated for three generic ships representing the world fleet of RoPax ships (Cargo, Standard, and Ferry RoPax) and a cost-effectiveness assessment was performed on six Risk Control Options (RCO), taking into account potential differences between newbuildings and existing ships.From a detection perspective, only the RCO Combined smoke and heat detection was found cost-effective for Standard and Ferry newbuildings (but not for existing ships).From a decision perspective, the RCO Improved markings/signage for way-finding and localisation and Alarm System Design & Integration met the cost-effectiveness criteria on all three generic ships, except for the Existing Cargo RoPax ships for the latter RCO. The RCO Preconditions for Early Activation of Drencher System was found cost-effective for Standard and Ferry RoPax ships.

FIRESAFE II Detection systems in open ro-ro and weather decks
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- One of the main issues with regard to fire safety of open ro-ro spaces and weather decks is that detection systems may not be as efficient as in closed ro-ro spaces. Several recent total losses of ro-ro ships have stressed the need for investigating more efficient fire detection solutions.This study evaluated available and emerging fire detection technologies for use in open ro-ro spaces and on weather decks. A review of relevant regulations was performed as well as an evaluation of the expected efficiency of the identified alternative detection technologies, considering detection time and sensitivity to weather conditions, loading conditions and deck configuration, as well as cost.Fibre optic linear heat detection and thermal imaging camera detection were selected for fire tests in open ro-ro space and on weather deck, respectively, onboard a commercial RoPax vessel. Both systems were found functional and suitable for the relevant ro-ro space environments. The risk reduction potentials of the systems were quantified and a cost-effectiveness assessment was performed. Thermal imaging camera detection was found cost-effective for all types of RoPax (Existing ships and Newbuildings), and fibre optic linear heat detection system was found cost-effective for Standard and Ferry RoPax (Existing ships and Newbuildings).
