Raising the alarm
by ArabianBusiness.com staff writer on Tuesday, 23 December 2008
Taking precautions
In seeking to prevent a spill, Self explains that it is first critical to undertake environmental impact and risk assessment studies so that the company knows where likely spills may occur, how to minimise any risk, and the short-term and long-term effects should there be a spill. Second is to have a thorough contingency plan for all eventualities so that anyone at the site of the spill can turn to the corresponding page and follow a ‘things to do' check-list.
"The single most important aspect of preparedness is generally thought to be the oil spill contingency plan or emergency response plan. This should be updated regularly and minor and major exercises should be undertaken as well as a comprehensive training programme for employees.
Most companies think that preparedness for an incident is solely about having equipment, but equipment is useless without personnel who know how to use it and deploy it, and the training of personnel is too often overlooked," explains Alex Spence, general manager of SEACOR Environmental Services Middle East.
"I think we need to promote institutional strengthening and capacity building within companies. This needs to start with training, putting the right
procedures in place and then ensuring that companies are able to disseminate the required information throughout all levels and make sure that all staff have the appropriate level of awareness and skills," declares Mahmood.
Despite vast improvements in the preparedness of many companies in the industry, shortfalls are still readily identifiable. Whilst operating companies may be better prepared, service companies that work alongside them are often unaware of the policies and plans, thus creating a loop-hole in the system.
"The onus is often on major oil companies and shipping merchants to respond to spills, but this needs to change. Responsibility must rest with the whole line of companies working in the sector - both upstream and downstream, those involved in logistics, handling and servicing. We need better communication and cooperation down the whole supply-chain and between industry and government," says Mahmood.
The buck stops here
In the dire emergency that is an oil spill, particularly at sea, time is of the utmost essence, thus lacking an adequate plan of attack and equipment can cost dearly. Examples abound of worryingly tardy responses, for example, the Pontoon 300 spill in January 1998.
Whilst under tow off the coast of the UAE, a barge ran into trouble, sank and it is estimated that it released 8000 tonnes of crude oil into the sea in the process. Oil eventually swept inshore - affecting beaches in five of the emirates and afflicting vegetation.
It was the hesitation of the UAE's government that causes alarm, with delays of seven weeks due to the barge not being registered or insured and no National Contingency Plan being in place to outline the chains of command and operational procedures.
Alongside this, the government's Federal Environment Agency had no equipment or expertise to deal with the spill, making them reliant on ADNOC's facilities.
Improvements in the UAE's government response have doubtless been made since the case of Pontoon, with the signing of various international protocols including the Kuwait Convention for all countries bordering the Gulf and arrangements assigning spheres of responsibility in the case of a spill.
Mohammed Meghani, assistant general manager of business development at Kuwait based NAPESCO:
Although it is the major offshore spills that grab the headlines and fill column inches, it is small onshore spills that are far more common. Knowing how to deal with them is imperative since it is not always the biggest spills that are most dangerous - a small spill near a water source can be catastrophic. So what can be done?
• Bio-remediation - biological agents and microorganisms can be applied to the affected area in order to help the breakdown of oil and expedite natural degradation.
• Removal - contaminated material can simply be removed and placed in land-fill sites.
• Thermal desorption - at certain temperatures oil will boil, this can then be captured and recondensed. What will remain after heating the contaminated material is solid mass, such as soil, that is free of any harmful contamination and meets environmental standards.
The oil too will emerge and be of a high enough quality to use. The soil that needs to be treated will be in concentrated areas, so clean-up equipment can be taken to the site and remediation undertaken on the spot, since it would not be cost-effective or practical to take all of the contaminated material to a plant.
As with most technology in oil spill remediation, desorption technology has been around for a while, it has just got more compact, easier to use and more environmentally friendly.
