OSCT Indonesia have combated more than 60 oil & chemical spills in Indonesia and around the world
including China, Qatar and Thailand supported by response experts that have more than 36 years ofexperience. Our most recent major oil spill is offshore spill at West Java near Jakarta.

Thousand Islands - Jakarta

The Thousand Islands (officially Kepulauan Seribu) are a chain of islands to the north of Jakarta's coastnear West Java. It consists of a string of 342 islands stretching 45 km (28 mi) and is a popular tourist areaand protected wildlife.

Boom & Skimmer Containment Calculation

Encounter Rate:
The rate at which oil and/or emulsion is
encountered by the skimmer
Encounter Rate (m3/hour):
Swath Width (m) x Thickness (mm) x speed(m/s)
Oil Boom Swath Width:
Circumference (C) = π D
Skimmer Recovery rate:
The rate at which a skimmer recovers oil

Swath Width: 255 m

Mooring Buoy

Parameter
Static boom configuration with brush/steel discoctopus skimmer.
Swath width of 255 m for 400 m oil boom.
Oil slick thickness is assuming 1 mm for crude
oil (black to orange).
Speed of 0.35 m/s (0.7 knots).

Oil Boom Swath Width Calculation

1,800 m3/day

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.
Oil boom: 400 m

Assume the oil volume fully trapped in boom configuration (320 m3/hour), 1 configuration ofoil boom with 3 skimmer system of 300 m3/hour recovery capacity can recover 320 m3/hour of
spilled oil.

One configuration of near source Static Oil Boom requires offshore boom ± 400 meters connected to two
mooring buoys and large skimmers that can recover contained oil to prevent oil from escaping

Double layer protection (second layer static boom) was implemented to fully contain the oil if some leaked
through the gap in between mooring buoys. In addition, dynamic boom on standby to contain in-case oilleaked from second layer static boom, hence total of 3 layers of near source containment.

Trained Responders for
Near-Source Containment© photos by OSCT Indonesia

To increase effectiveness & efficiency of near source containment, each deployment/skimmer vessel has 3
responders and 1 supervisor accredited OPRC IMO 1 and 2 by Nautical Institute that supervise equipment
deployment safely and to avoid boom & skimmer damage for over 2 months 24/7 operations

The oil was emulsified, hence dispersant was not effective but can be contained effectively with oil boom
and recovered during day time with brush/steel disc type skimmer assisted with vessel water pumpflushing. Oil was pumped to IBC tanks onboard skimmer vessel and transported daily to barges via cranewww.osct.com

Shoreline Protection with Pre-SCAT & Drone/ UAV

Pre-SCAT

Drone Surveillance

UAV Surveillance© Pictures From News Outlet
Pre-Shoreline Cleanup Assessment Technique (SCAT) using trained specialist, drone and Unmanned Aerial Vehicle (UAV) using
geotag photo and video needs to be done before the incident occurred, in order to determine appropriate response strategy, amountof equipment and logistic mobilization in certain area.
For surveillance drone is easier to use but has distance of only 2 to 4 km, whereas UAV requires clear area to launch and land but withlonger distance up to 20 to 40 km depending wind on condition. For offshore survey due to high wind helicopter iswww.osct.com
safest option.

21

Recovery Containment & Shoreline Protection

Protection Strategy© Pictures from News Outlet

Oil spills that is detected heading to shoreline is recovered using oil boom, vacuum skimmer andabsorbent. To prevent oil from entering river/settlement area, protection booming is deployed as priority.

22

Shoreline Response Supervision and Training© Pictures from News Outlet

For this response there are over 2,000 personnel consisting of local community, army and local boats.
These personnel required daily supervision from 100 accredited IMO supervisor. Safety training andadequate PPE is required before operation and first priority is safe operation using equipment such as oilboom, vacuum skimmer, pressure washer and absorbents.

1st layer of 4200 meters and 2nd layer of 400 meters offshore boom and 3 skimmers was deployed on 10 th August 2019,
1st layer of 4150 meters and 2nd layer of 1300 meters offshore boom and 5 skimmers was deployed on 22 nd August 2019.
It can be seen oil recovered significantly from 400 KL/day on 10th August 2019 to 2000 KL/day on 22nd August 2019 since offshoreboom installation increase over 1000 meters and 2 skimmers.
This shows as more static boom installed, more oil can be contained and recovered by skimmers.

It can be seen that more deployment of onshore boom requires more responders and resources.

Summary Lesson Learnt

OSCP COMPLETE WITH ESI & SCATOIL SPILL RESPONSE TRAINING

In major spill incident involving combined stakeholder coordinationfrom private sector and government, important to have contingency
planning complete with ESI & SCAT to increase response process.
Consideration of using unified coordination

To increase oil spill response especially in shoreline response
regularly training need to conduct. This purpose of this training is toimprove oil spill response equipment, personnel, logistics, and local
resources capability & preparedness

LOGISTIC & STAGING AVAILABILITY MAPPINGEFFECTIVE RESPONSE STRATEGY

In oil spill response, availability of logistic is the key to speed up
response activates and mobilization of equipment. Therefore logisticalavailability must be mapped beforehand to simplify and speed up
response activities

Near source containment static boom is an effective response strategy
able to work 24/7, and is efficient because it does not require vessels
to operate once moored. This is now adopted as standard strategy foroil spill contingency plan and response in Indonesia.
