Introduction

At around 0630 hrs when Oman Blend crude oil was transferred from the oil tanker through the single
point mooring (SPM) to the pipeline for delivery to the refinery, the leak occurred in a 16” diameter
marine hose at the SPM, located 20 kilometers south of the Map Ta Phut seaport in the Gulf of Thailand(Lat-Long: 12°29’12.6”N, 101°11’57.8”E). A patch of oil slick reached Ao Prao bay, the northwest coast ofSamed island, contaminated the coastline.

Incident Summary

The Off shore crude transfer facility which located about 10 miles away from South of the Map Ta Phutseaport area. The single point mooring (SPM) was installed with hard pipelines on the seabed,connected SPM to the refinery facility. Transferring crude oil from the oil tanker to the SPM used 2strings of floating hose connected from the SPM. Each string comprised of a 16” and a 24” diameter
flexible hose connected together with a 24”/16” concentric reducer installed between 16” and 24”
pipeline. At time of incident, an oil tanker was moored at the SPM to transfer crude oil. After thepreparation was completed, the transfer began at 0600 hrs. The pressure at the tanker manifold was
slowly increased to the normal operating pressure at 0616 hrs. At 0630 hrs, an immediately leaked atfloating hose was observed. The leak occurred from a 16” hose section 1.7 meter breakaway coupling.
After investigation, there was confirmed that the damage of floating hose was not came from theOperation practices and operating condition.

Incident Response

The incident response effort was collaboration between PTTGC, Royal Thai Navy, Royal Thai Army,
Marine Department, the Mayor of Rayong province, Department of National Park, Wildlife and Plant
Conservation (DNP), Pollution Control Department (PCD) and Industrial Estate Authority of Thailand(IEAT). In preparation for oil spill control, the emergency response team also requested support from Oil
Industry Environmental Safety Group Association (IESG) and Oil Spill Response Limited (OSRL). ORSL wasrequested to support aircraft for aerial dispersant spraying operation. However, the aircraft arrived latethan the schedule and caused the spraying operation to begin when the oil patch was already closed tothe Samed Island.
The oil dispersants used in the oil spill control operation were Slickgone NS and Superdispersant. Both ofthem were approved by Pollution Control Department (PCD) to be used in oil spill control. Thesedispersants were biodegradable without bioaccumulation, mutagenic effect and teratogenic effect.

Mutual Industry Organization in Thailand
Oil Industry Environmental Safety Group Association (IESG) is the non - profit organization and thePetroleum Industry Cooperative Organization for Excellence in Safety and Environment. The jointly
Organization set up by most of Thai Petroleum Companies as Oil Industry Environmental Safety Group
Association (IESG) occurred since 1968 with objectives of voluntary group and Non-profit making
organization includes safety and environmental impact prevention and provision of mutual aid/assistance in case of emergency among IESG Members.
Currently the member of IESG consists of 20 Petroleum Companies in Thailand and also included
Government Organization which considered as Executive Members as follows: Marine Department,
Department of Energy Business and Department of Disaster Prevention and Mitigation. IESG Member
was playing important role on immediate spill response support i.e. equipment, dispersant , manpoweretc.

Initial Lesson Learned
5.1 Communication: Lack of clarity in communications between party concerns which result in delay
support.
5.2 Shoreline Clean up:
5.2.1 There was not a proper site setup, for instance, no boundaries of work zones, security, ordecontamination area. This issue was highlighted to the on-scene commander and the situation wasgreatly improved on the following day.
5.2.2 Groups of worker from different parties participated in the cleanup operations. Crowd control
became a major issue since no clear common instructions were given to them. Therefore, the sitesupervisor was assigned on the following day to oversee the cleanup operations.
5.3 Crowd and Media: A lot of media and Crowd of People presented on site and there was no security
plan in place to refrain the media from entering the area especially during Shore Line Cleanup process
and get difficulty to control the media release.
5.4 Own Capability and Logistics Support: Review of stock pile, dispersant spraying tool, Boats etc. More
importantly on Oil Spill Knowledge and understand on how to handle the situation once incident raised.

The logistics support is considered one of the most challenged since this spill occurred in sensitive andremote location and difficult for heavy equipment to reach.
5.5 National and Industry Level: All related parties should evaluate national and provincial emergency
response plan to cover the oil contaminated coastline scenario and conduct the emergency response
drill periodically. Mutual Industry supports are considered more important in spill response. The
industry capability enhancement is to be review including necessary process.

Conclusion and Way Forward

The Crude Oil receiving facility is now back in normal service with additional mitigation measures inplace. However, we have to remind that once spill happen, the present of public concerns and extreme
environmental perception which considered significantly to related parties. In order to continue
operation and minimize risk of spills in the future, the knowledge gain and lessons learned from thisincident will be one of contribution factor for future development of our industry. Nothing Impossible!!.
