ABSTRACT
On numerous occasions, East Asia has been affected by marine oil spills incidents, originating from tankers and other types of ships. Important spills incidents that involved the IOPC Funds in the last decade (e.g. Nakhodka, Evoikos, Natuna Sea and Solar 1 …) indicate an average occurrence of one spill per year. This figure remains significantly high when considering that some States in the region are still not parties to international compensation regimes. In addition, numerous incidents do not benefit of international media coverage, thus making them often unnoticed.
Lower scale incidents (within the range of hundreds of tonnes) occur on a more frequent basis and may appear trivial to respond to. Nevertheless, they represent the same range of difficulties experienced during larger scale incidents (logistics, suitable means to apply dispersants promptly and effectively, availability of temporary storage, lack of plan and training …)
In terms of response, the ultimate authority in the coordination of spill response activities is in the hands of Government Agencies. However, the equipment and manpower available belong in various proportions to both Government Agencies and the Oil Industry.
The latter operates numerous oil terminals and offshore facilities and is responsible to respond to minor spills defined as Tier 1. In the case of a large spill that exceeds the on-site capability, Tier 3 Cooperatives funded by the vast majority of major companies were created to assist and complement the local response, by offering access to a large range of special supplementary resources and services, such as the Airborne Dispersant Delivery System.
Whilst Tiers 1 and 3 are well defined and are respectively synonyms of small and huge oil spill incidents, there is a lack of clarity and consistency in-between, thus making the Tier 2 response difficult to define. This gap that is often underestimated and may result in a preparedness weakness leading to unfortunate consequences.
The aim of this paper is to analyse the Tier-2 response requirements and to discuss on the challenges of implementing effective measures in a region where the only imports of crude oil of China have more than doubled in the past five years.
