the criminals are becoming more efficient, or crude theft is occurring increasingly elsewhere,” the report says.
A breakdown of Nigeria’s losses in NEITI’s report shows that $38.5bn was lost on crude theft alone, $1.56bn on domestic crude, and another $1.85bn on refined petroleum products between 2009 and 2018. NEITI says that as the country faces dwindling revenues from its oil industry, prevention of oil theft must become a priority in order to expand revenue generation.
“In terms of volume, 138,000 barrels of crude oil were lost every day for the past 10 years, representing 7% of the average production of two million BPD. Nigeria lost more than 505 million barrels of crude oil and 4.2 billion litres of petroleum products between 2009-2018,” the report continues. NEITI also identifies several other effects from oil theft in Nigeria, including costly pipeline vandalism and criminal sabotage, as well as illegal refineries which endanger local communities.
The agency has also called for a special security task force to be created made up of oil companies and technical experts to help minimise theft and vandalism. NEITI has said the team should focus on improving response time to incidents and have access to real-time data provided by leak detection and localisation systems installed and operated by oil companies.

Wearable technology eliminates microsleeps The Life series of products, developed by Australia-based SmartCap, are wearable technologies that help prevent microsleeps by providing accurate alertness measurements in real-time to operators and drivers. While there are several technologies that react to a person showing signs of fatigue, Life proactively monitors the initial stages by alerting an operator before symptoms of fatigue progress, enabling them to better manage their fatigue. The LifeBand can be attached to several types of headwear, including hard hats and caps, or can be worn on its own. It then monitors fatigue measurements by using a method called EEG (electroencephalography) technology that measures the electrical activity of the brain. Workers can monitor their fatigue levels in real-time via Bluetooth using the LifeApp. The

The endless stream of visualisations presented to an operator can be overwhelming and it’s worrying to think how an operator may respond if similar events were to take place today. While it’s lucky that no-one was severely injured, the incident reinforces the need for alarm annunciators. These are physical panelbased alarms that are hard wired directly into each process and capable of sounding and lighting the relevant window in the event of a critical breach in containment. The HSE’s findings show that, had more effective alarm systems been in place, staff at the site may have had a better chance of preventing such catastrophic circumstances and perhaps avoided the subsequent rebuild cost of £48m at the time – or over £96m today.

This is achieved by chemical coating the garments in order to repel any contaminants and preserve the properties within the clothing. Testing for this standard consists of a ‘mannequin test’, in which the wearer must perform 7 basic movements and the permeability of the clothing to chemical is subsequently determined.
BS EN 14404 BS EN 14404 relates to trousers and coveralls which offer kneepad pockets to protect the wearer when kneeling. Knee pads are tested based on three properties – penetration resistance, force distribution and shock absorption. Two levels of protection can be provided according to BS EN 14404. Level 1 requires kneepads to provide protection against objects more than 1cm high. Level 2 requires pads to be able to withstand use under heavy conditions such as kneeling on stones in mines and quarries.
