1930-1970: Urban 	expansion	 and 	the	 car

DSB’s	 independent	 assessment	 	
In Norway, DSB (	the	 Directorate	 for 	Civil	 Protection	) is 	responsible	 for 	civil	 protection	, 	covering	 national	, regional and 	local	 preparedness	 and 	emergency	 planning, fire and 	electrical	 safety	, 	safety	 in handling and 	transport 	of	 hazardous	 substances	. 	- 	DSB reports to 	the	 Ministry	 of	 Justice	 and Public Security. 	 DSB 	published	 an 	independent	 risk 	assessment	 of	 Oslo 	harbour	 	(Sydhavna	), in 	February	 2014. 	- 	Based	 on	 publicly	 available	 data and data 	requested	 from 	involved	 parties	. 	- 	Based	 on	 interviews	 and 	meetings	 with	 involved	 parties	. 	- 	Based	 in in-	depth	 investigations	 into	 certain	 topics

vista&	analyse.no	-	
DSB’s	 findings	 (	selected	) 	
• 	Many	 involved	 parties	 and different types 	of	 activities	 make 	coordination	 a 	challenge	. 	• 	Extensive	 information	 flows	, but	 not 	filtered	 to 	ensure	 that	 the	 right person 	will	 	have 	the	 right 	information	 in case 	of	 an 	emergency	. 	• 	Different risk management systems 	among	 different operators; 	need	 for 	better	 	coordination	. 	• 	Many	 different risk 	assessments	 made	 for different 	activities	 (made	 when	 	permission	 was	 sought	), 	but	 lack	 of	 a risk 	assessment	 looking	 at 	the	 totality	. 	• 	Lack	 of	 a system for 	continous	 risk 	assessment	 	• 	When	 assumptions	 for a risk 	assessment	 changes	, a 	new	 risk 	assessment	 is not 	automatically	 carried	 out

Risk 	factors	 	
From 	the	 anonymous	 survey 	conducted	 with	 harbour	 operators 	- 	85% 	considered	 the	 ship-trafick	 risky	 ”to 	some	 extent	” 	- 	69% 	considered	 the	 car	 traffick	 risky	 ”to a 	significant	 extent	 (31%) or ”to 	some	 extent	” (38%) 	- 	45% 	considered	 container 	operations	 risky	 ”to 	some	 extent	”

Risk scenario 
A 	ship	 transporting	 fuel	 collides	 with	 another	 ship	 or 	runs 	aground	 by Hovedøya/Bleikøya 	islands	. This 	results	 in a 	fuel	 leak	 which	 is 	ignited	 and 	begins	 	drifting	 towards	 central	 Oslo. Southern 	wind	 	direction	, 2 m/s. 	The 	map	 shows 	dispersal	 of	 fumes	. 	- 	Red 	colour	: Exposure	 for +1h 	gives	 life-	threatening	 health	 effects	. 	- 	Blue 	colour	: Exposure	 for +1h 	gives	 temporary	 	negative 	health	 effects	.

Recommendations	 and 	follow	-up 	
• 	Stronger	 involvement	 of	 the	 municipality	 to 	ensure	 overall risk management. 	• 	Improved	 communication	 and 	coordination	 between	 ”	external	” stakeholders; 	municipality	, 	harbour	 authorities	, relevant 	ministries	 etc. 	• 	Improved	 communication	 and 	coordination	 between	 ”	internal	” stakeholders 	at 	the	 site	. 	 • 	HarbourEx15 (April 2015): A full-	scale	 emergency	 exercise	 	• 	A 	serious	 accident	 scenario is 	played	 out	 	• 	All 	emergency	 response	 agencies	 respond	 as in-real-	life	 	• 	The 	response	 is 	documented	 and 	evaluated	 to 	improve	 response	 	• 	EU support and 	international	 participation
