IMO New Rules

Casualty threshold not exceededSafe return to port concept.

IMO Goal, ”Ship is its best lifeboat”In the event of casualty, persons can stay safely on board as the ship proceed to port.

Improve ships survivability in the event of collision, grounding, fire or systems failure.

Casualty threshold exceededTime for evacuation and abandonment

Safe Area ConceptCasualty threshold is the amount of damage a ship is able to withstand and still safely return to port.

Essential systems to remain operational. 3 hours.

Fire Protection Damage Stability Safe Return to Port LSA

Main fire zones

- Max length 40 m

- Max area 1600 m2

Alternative design

- apply Ch. II-2 Reg.17

- length and area can be increased

IMO probabilistic rule

- required index R

- R = f ( Length, Pax )

- R = 0,6...0,9

Existing rule

- 75% in lifeboats

- 50% in rafts or MES

Large lifeboats

- 250…400 persons

- boarding in stowed position

Large MES

- 450 persons

- boarding through chutes
