Abstract

The Macondo blowout in the Gulf of Mexico in 2010, and the earlier Montara incident in Australia, led the entire oil and gas industry to review both drilling safety and oil spill preparedness. As a result, the International Oil and Gas Producers Association (IOGP) established a multi-year programme to embed the learning from these and similar incidents, and to enhance future prevention and preparedness. This presentation provides an overview of the latest practical tools that can be used by operators to improve their emergency and spill response plans.

Introduction

The Macondo blow-out in the Gulf of Mexico in 2010, and the earlier Montara incident in Australia, led the entire oil and gas industry to review both drilling safety and oil spill preparedness. As a result, the International Oil and Gas Producers Association (IOGP) established a multi-year programme to embed the learning from these and similar incidents, and to enhance future prevention and preparedness. This presentation provides an overview of the latest practical tools that can be used by operators to improve their emergency and spill response plans.

New Techniques from the Macondo Response

The Macondo response in particular resulted in a number of innovations as a result of the scale and complexity, and technically challenging conditions. More than 150 companies and multiple government agencies were involved in tackling the sub-sea blowout and spill, all under the overall direction of the US Coast Guard in the Unified Command: Ó Unique sub-sea operations, including capping and containment, were conducted about 50 miles from shore, in around 5000 feet of water, at sea bottom temperatures of about 3 degrees Centigrade Ó Over 48,000 responders were mobilized across five US States along the

Gulf of Mexico coast Ó Over 6,500 vessels and up to 120 aircraft were deployed during the response Ó Over 13.5 million feet of boom were deployed Ó Around 50 surface vessels and up to 16 Remotely Operated Vehicles were operated within a tight radius of a mile over the well site – managed by large-scale simultaneous operations. The well flowed for 87 days before being capped and this was the largest spill response in history. Many innovative techniques were developed and applied for the first time at this scale. These included: Ó Sub-sea dispersant injection to disperse oil at the well head Ó Controlled burning of oil slicks on the sea surface for extended periods Ó Satellites, infra-red and ocean vehicles for spill tracking and sea monitoring Ó ‘Common Operating Picture’ information systems used to manage huge amounts of disparate data in support of the response Companies, industry associations and governments worked quickly to capture and apply the learning from these events. At the Global level IOGP assembled the Global Industry Response Group and progressed programmes on well incident prevention, subsea well intervention (including capping and containment), and oil spill preparedness and response.

Sub-Sea Well Response Project

The sub-sea well response project was progressed in partnership with Oil Spill Response Limited (OSRL) and the resulting system comprises: Ó Four well capping systems – located in Brazil, Norway, South Africa and Singapore, that can be shipped to an incident location Ó Well containment toolkits – which can be used with standard industry equipment to bring flowing hydrocarbons from the well-head to the surface for storage in the event the well cannot be shut in Ó Two supplementary hardware sets – comprising: Ó Site survey equipment (including sub-sea sonar) Ó Debris clearing equipment to enable access to a blow-out preventer (BOP) Ó Subsea dispersant application equipment Ó High pressure high volume accumulators for closing a BOP More information on the Subsea Well Response Project is available at: http:// subseawellresponse.com.

Oil Spill Preparedness and Response Project

The oil spill response recommendations were progressed in a joint industry programme (OSR-JIP) managed by IPIECA – the global oil and gas industry association for environmental and social issues. 19 companies have invested millions of dollars of effort in the 5-year programme to produce a completely revised and updated suite of guidelines incorporating the experience from the Gulf of Mexico response

Summary and Conclusions

The industry has invested millions of dollars to revise and update oil spill guidance, and incorporate the learning from Macondo, Montara and similar incidents. This has produced 24 Good Practice Guides, 15 technical guides, 3 research papers and 2 Recommended Practices. Only a small sub-set of the newly available resources has been shared in this presentation. The key developments and considerations include: a.Major accident risk analysis should be the starting point for developing response plan scenarios b.Net Environmental Benefit Analysis (NEBA) should be used during planning to help identify the optimum response strategies for the different spill circumstances c.Response plans should identify in advance which resources are sourced locally, regionally or globally using the latest guidance on Tiered Response and Preparedness. d.The industry recommended Incident

Management System (IMS) guidance should be considered when reviewing response organisation structures and procedures to enhance potential collaboration and ability to scale-up a response e.The latest guidance on oil spill response equipment and techniques should be incorporated into response plans, training and exercises f. Government and community stakeholders should be involved throughout the planning, response and followup lifecycle to enhance transparency, speed and effectiveness of response.

HOT OIL FLUSHING

Helium Leak Detection is used as a final commissioning test to provide operator confidence in the safety and environmental integrity of new and existing processing facilities. The Helium leak test is then carried out by injection the 1% Helium and 99% Nitrogen test gas mixture into the system in controlled pressure stages until the test pressure is achieved. The recommended test pressure is the maximum allowable working pressure or up to 95% of relief valve set pressure.

CALIBRATION SERVICES

Ó Calibration for pressure gauges up to 30 KPSI (Analog &Digital) Ó Calibration for pressure recorder (Renting and repair) Ó Calibration for tong torque and tong line pull systems Ó Calibration for silo tanks weight indicator systems. Ó Length measurement tools (verniercalliper- micrometers)

HIGH PRESSURE WATER JETTING

FMS (PL&IS) offers jetting equipment capable of working at ultrahigh pressures for the removal of inner preservation coatings, paints and accumulated hard scale. High-pressure jetting hoses can be used with both static and rotating nozzles and fluid supplied by either electric- or diesel-driven pumps. Hydro jetting can also be used on external surfaces, reducing the need for sand blasting or removing the hard scale.

Hady Meiser Egypt is an Egyptian German joint venture investment that manufacture bar gratings with high quality and prices than their imported which used in various fields as petroleum companies –Power stations – Cement companies – Fertilizers company , spiral stairs and slitting coils.

Hady Meiser grating is acknowledged by trade specialists to be one of the best product of its kind in Europe , It›s a fair assessment , we feel and part of the reason is undoubtedly the committed work of our planning department and our reliable delivery dates.

What is the gratings ? Try asking non- experts what a grating is « a grating ?» , most of them will reply « a grating is a kind of floor on which you can stand safely, but when you look down , you get the feeling you›re standing in mid-air. Indeed , more than 80% of any grating does exist of holes, we simply exploit the fact that a strip of metal positioned . Perpendicularly and anchored securely can carry substantial load.

Gratings Specification : our gratings enjoy various specifications they have different sizes of bearing bars starting from 25x 3 mm . up to 50 x 5 mm and fences . and twisted cross bars 5 mm. or 6 mm in addition to the possibility of manufacturing the serrated grating which are specially made for the petroleum companies

Slitting coils : In addition that it has been inserted a new production line for rod slitting coils ( black-galvanized – hot – cold ) in thickness starting from 1 m up to 4 mm.
