Introduction
Unproductive ields and current oil prices have led to an increase in
decommissioning of upstream facilities and operators are now looking
at diferent factors in order to safely close the ields and retire the assets.
Oil and Gas ields are many times developed in areas with great Marine
and Coastal Biodiversity resources. Biodiversity was deined by the
United Nations Environmental Program [1] as the variability among
living organisms and the interrelated and complex linkage within
species, between species and ecosystems. Decommissioning of oil and
gas infrastructure may afect the fundamental biodiversity at both the
site of decommissioning and other interrelated locations.
Oil and Gas operations have been identiied as among the world’s
most polluting industries according to he 2015 World’s Worst Pollution
Problems [2], consequently it is not only important but imperative to
address issues related to decommissioning now before further activities
in this sector adds additional stress to the environment already
weakened by climate change and other human activities. In order to
meet challenges in the upstream sector the Energy and Biodiversity
Initiative (EBI) was formed in 2001 and ceased in 2007. he EBI
was made up of leading energy companies e.g. Shell, Statoil, Bp and
ChevronTexaco and conservation organizations, e.g. IUCN, TNC, FFI
and he Smithsonian Institution and its aim was to produce practical
guidelines, tools and models for integrating biodiversity conservation
into upstream oil and gas development. Now when upstream activities
are about to cease, the industry is missing these important guidelines
and initiatives, nevertheless must deliver the decommissioning
activities in an environmentally efective, eicient and equitably safe
manner not only for the operators and the regulatory authorities but
for the physical and biological surroundings. One issue that derives
from applying decomissioning activities is whatever the diferent
decommissionings options may impact diferently on the environment
and the related biodiversity and bidiversity functions.
When an oil and gas company is operating in areas that sustain
high biodiversity they essentially integrate more considerations into
the planning and decision- making process. hese considerations may
include latest and best scientiic research, and community engagement
to strengthen capacities and support transparency. As observed in many
ofshore concession areas, by prevention of human intrusion into the
oil ields, the biodiversity and abundance is many times higher inside
than outside the project area. hese ofshore areas function as marine
protected areas and “no take zones” or as a network of small protected
areas for source populations that may bring inlux of organisms and
richness to other areas. his indirect and positive efect of the assets
would disappear for a particular location when the asset goes for
onshore recycling or is converted in an artiicial reef or disposed of in
deep waters. hese potential negative impacts on biodiversity from oil
and gas decommissioning are diicult to estimate.
Decommissioning may impact directly and indirectly on biodiversity
and the impacts may be caused both during and ater decommissioning
depending on the selected decommissioning option and the associated
activities and other issues like technical expertise and methodologies.
he direct impacts may be alleviated with mitigation measures drated
in the impact assessment; however the indirect impacts are diicult to
estimate quantitatively or qualitatively and may have a large impacts
(positive or negative) resulting in changes to the local food webs either
through bottom-up or top-down related feedback. Because of this it
is important to understand the potential impact on biodiversity of
diferent decommissioning options. Impacts on biodiversity, whether
negative or positive, can be monitored using indicators, which provide
a measure of change in the surrounding environment. Without an
establishment of these parameters and in the absence of a consistent
regulatory and policy framework, decommissioning programs are let

Abstract
Decommissioning of offshore oil and gas platforms raises many complex issues to consider before accomplishing
a successful strategy to undertake these activities in an environmentally effective, eficient and equitably safe manner
not only for the operators and the regulatory authorities but for the physical and biological surroundings. There are
many factors to evaluate and issues like liability, reputational risk, cost, cumulative impact, technical development,
regulatory framework, and climate change would all have to be considered on a case-to-case scenario as opposed
to adopting a regular strategy for all facilities. The debate is focused about whether the structure or facilities left in
place or like an artiical reef habitat constitute valuable habitat and deliver ecosystem services, or in contrast impact
the biological environment and should be removed. Some offshore facilities, although deployed as artiical reefs for a
very long time, have not developed the diversity of benthic or ish assemblages comparable to that found on natural
reefs. South East Asia hosts many aging offshore facilities and the shortage of decomissioning yards and a lack of
policy framework and inancial support play a big role in order to conduct these activities in a way that safeguard the
environment and the biodiversity of the marine environment.
