Based on the experiences responding to major oil spill incidents, national OSRO, such OSCT Indonesia role is changing and emerging to support Tier-1, Tier-2 and Tier-3 International response. From the Japanese carrier oil spill incident, in-country resources are the first response to arrive on-site to recover the spilled oil because no equipment is available on-site and hence the role of the national OSRO becomes first responders as some companies does not have Tier-1 resources.

 

 

From the Sumatra, Selat Panjang tier-2 oil spill incident, it can be seen that mutual assistance from the area is limited because the oil and gas companies can only release about twenty five percent (25%) of its Tier-1 resources. Other mechanism that can be used to respond to tier-2 oil spill incident is from membership program by national Oil Spill Response Organization that provides more Tier-2 Resources that can be mobilized quickly, hence the role of the national OSRO is not only for Tier-1 response, but to respond to Tier-2 Major oil spill incidents. Furthermore, from International oil spill incidents, it is proven that having a MoU between Tier-2 and Tier-3 Oil Spill Response Organization allows more resources to be mobilized during an oil spill response. 

 

The role of the national OSRO by having a MoU is also Pre-arranged custom clearance that allows equipment to come into the country without delay, logistics and having a standard operating procedure for operations of national and International teams. The role of National Oil Spill Response Organization like OSCT Indonesia are changing, emerging from providing Tier-1 and Tier-2 Response to assisting Tier-3 response beyond borders by having an cooperation (MoU) with Tier-3 Oil Spill Response centres to allow international resources to come into the country quickly by preparing pre-arranged customs clearance, local logistics, and clear standard operating procedures.
