OSCT Mission

Map Legend

To support the Indonesian Government target towards oil production 1 million barrel per day, our mission
is to protect Indonesia’s & World’s natural environment as Indonesia’s largest spill combat center & oneof the largest in the world. With 85% of its territory is ocean, Indonesia has big risk of spill pollution fromoil & gas operation which can pollute sensitive areas & world heritage sites.

OSCT was activated on 8th August 2021 and carried out trajectory modeling and satellite radar to see oil movement andparallel support operations on site, the team arrived on 9th August 2021 with a physical breakup / mechanical dispersion
countermeasure strategy, and started a dynamic / static boom on 13th August 2021 (waiting for supply vessel/AHTS as
mother vessel) and installation will be completed on 29th August 2021. On 18th October 2021 the spill source has beensuccessfully closed.

Skimmer Performance Calculation* The Skimmer recovery rate effective is 100 m3/hour**Assuming 6 hours response period in a day.

Oil volume analysis based on aerial, the oil is 20% (at 09.00) of the configuration (64 m3/hour)
Therefore 1 configuration of oil boom with 1 skimmer system of 100 m3/hour recovery capacity can sufficiently
recover 64 m3/hour of spilled oil.
Assume the oil volume fully trapped in boom configuration (320 m3/hour), 1 configuration of oil boom with 3
skimmer system of 300 m3/hour recovery capacity can recover 320 m3/hour of spilled oil.

The containment static boom localizes about 20% of the total 350-400 m oil boom, requiring a minimum of
1-2 skimmers to operate with a capacity of 64-100 m3/hour.

As a response strategy, mechanical dispersion in Langsa Spill quite effective for light oil types. Using the
ship's propeller and fire monitor.
When the oilboom configuration has been deployed, mechanical dispersion is used to break up the oilthat escapes the oilboom configuration. Dispersant is not effective for light oil

Shoreline protection preparedness required when oil spill occurs offshore, as a preventive strategy before oil spills reachsensitive areas, carried out every day using ships and drones to get wider observations with a distance limit of 2-4 km.
drones using geotagged photos and videos are prepared before an oil spill incident occurs so that the response process
runs effectively and efficiently.

which could lead to
miscommunicationand miss datainterpretation.

Oil spill response for Langsa Spill, is quite challenging due to occur in the pandemic Covid-19 situation, total personnel
onboard about 252 for SERT must through screening test (PCR/Antigen) and quarantine for several days before on duty. In
addition, technical meeting and situation report conducted by online/virtual mode which could lead to miscommunicationand miss data interpretation.

Summary Lesson Learnt

OIL SPILL COMBAT PLAN & PREPAREDNESSEFFECTIVE RESPONSE STRATEGYFor oil & gas operation, it is important to have approved contingency
planning complete with ESI & SCAT for effective & quick response.

Static boom strategy effective for continuous spill, in which supported by live
trajectory modelling with accountable data form BMKG (national agency forweather forecaster)/LAPAN BRIN Satellite Radar, verifying with actual
conditions based on chopper/vessel surveillance. It requires also planning forresources mobilisation.

RESPONSE DURING COVID-19
In a COVID-19 pandemic situation, very important to have a Health Protocol which integrated with Incident Management Team (IMT) and Site
Emergency Response Team (SERT) activities. IMT could activate and work online supported by virtual conference/software and Health Protocol onsite
supported by the HSE team.
