As a leading indigenous Integrated Oilfield Service Company that focuses on continuous improvement, RusselSmith Nigeria recently trained a fresh batch of engineers on implementation of the Pulsed Eddy Current Testing method. The Pulsed Eddy Current technology is a quick and…
Maritime safety is a key aspect of offshore practice. In order to avoid disasters and maintain crew and environmental safety, it is mandatory to perform certain routine checks to verify the integrity of marine facilities such as vessels, on a scheduled basis.
Classification societies act as regulatory bodies for these standard checks. They are responsible for controlling standards on behalf of insurers and they also control functions on behalf of the flag state.
In other words, classification societies carry out fair standards-based assessments of the integrity of marine vessels, with all stakeholders’ interests in mind. Such classification societies include DNV-GL, Lloyd’s Register, ABS, Bureau Veritas, etc.
Traditionally, these vessels are expected to dry-dock for inspection. A typical dry-docking process entails taking the ship to a shipyard for servicing operations.
Lifting, holding, putting down, pushing, pulling, carrying or moving of a load are manual handling activities carried out by one or more workers. Manual handling occurs in almost all working environments (factories, warehouses, building sites, farms, hospitals, offices etc) and the load carried can be animate (a person or animal) or inanimate (an object).
Lifting heavy objects increases the risk of lower-back pain and fatigue that can lead to an increase in muscle activation, stretch of ligaments and posterior disc, and loss of balance.
Unmanned aerial vehicles (UAVs), also commonly referred to as remotely-piloted aircraft systems (RPAS) or drones, are aircraft that carry no human pilot or passengers, and are controlled remotely by human operators or autonomously by onboard computers.
These autonomous flying machines are growing smarter, faster, and more versatile with each passing year, and advancements in UAV technology have opened up a whole new set of applications ranging from surveys to security surveillance, traffic monitoring, parcel delivery services and aerial photography.
Four teenage girls: Duro-Aina Adebola, Akindele Abiola, and Faleke Oluwatoyin, and Bello Eniola figured out a way to use a liter of urine as fuel to get six hours of electricity from their generator.
The invention was displayed at the annual event Maker Faire Africa, Lagos, Nigeria, an event that showcases ingenuity. The idea of using urine as fuel is not new but Bola, Biola, Toyin and Eniola came up with a practical way to put the idea into action and many households can really appreciate this.
How It Works
As explained on the blog of makerfaireafrica.com website, its process is itemized below;
- Urine is put into an electrolytic cell, which separates out the hydrogen.
- The hydrogen goes into a water filter for purification, and then into a gas cylinder, which looks similar to the kind used for outdoor barbecue grills.
- The gas cylinder pushes the filtered hydrogen into another cylinder that contains liquid borax, in order to remove moisture from the gas. Borax is a natural mineral, commonly used in laundry detergent.
- The hydrogen is pushed into a power generator in the final step of the process.
You might be wondering; wont hydrogen pose an explosion risk? The smart girls used one-way valves throughout the device as a safety measure. The urine to power technology needs to evolve further before such a system is feasible, at least as far as applications like powering generators used in most African households go.
Lamps Powered by Plants: Approximately 42% of rural areas in the Peruvian jungle suffer from a lack of electricity, according to Peru's latest National Household Survey conducted by the National Institute of Statistics and Information. This problem brought about a…
One of the longstanding problems facing the global oil & gas industry has been how to efficiently detect corrosion under insulation (CUI) in pipework. Over the years, a plethora of non-destructive testing (NDT) solutions have been developed to solve this problem with varying degrees of success. One technology that stands out however, is Guided Wave Ultrasonic Testing (GWUT).
Guided Wave Ultrasonic Testing works by generating mechanical stress waves that propagate along an elongated structure while guided by its boundaries. The generated waves can travel a long distance with little loss in energy, thus making them efficient.
We are in an era where the use of robotic systems to create simplified solutions to business challenges takes precedence. The robotic crawler is one of such highly efficient systems.
In a research article on the benefits of robotic crawlers by GE, it is stated that one third (540,000 km / 335,000 miles) of all pipelines worldwide are considered unpiggable because of access and valve restrictions, multi-diameter designs, impassable fittings and a myriad of other configuration issues.
Nevertheless, regulations exist that ensure these pipelines must be inspected on a continuing basis and that safe working conditions must be maintained to guarantee a long and profitable life span. Failures in pipelines usually result in incidents that can have devastating impacts on life, reputation, production, management and the environment.
With the epileptic power supply in most parts of Nigeria and most recently, the rise of petrol price to N145/ liter, Nigerians have found it expedient to plan their day to day activities to achieve more with less.
Have you ever been in a situation where you needed to iron some clothes urgently and then you experienced a power cut after some seconds of ironing? Very frustrating!
The recurring nature of this particular problem is what prompted a Nigerian innovator- Ayokunle Adeniran, an alumnus of Covenant University, to find a solution. Ayokunle’s invention is called the “Iron Rhino”, a pressing iron that does not need electricity or coal to work! Sometimes innovation from Nigeria seems very difficult, as many factors tend to be militating against creativity. However, successful people have learnt to put their excuses behind and forge ahead.
Unmanned aerial vehicles (also referred to as drones) have been used in a lot of applications lately, such as photography, movie-making, aerial surveys, and even in warfare, where they have shown distinct advantages in reconnaissance and attack. However, their commercial use in the energy sector is just getting under way, and is rapidly gaining popularity due to their versatility and wide range of applications.
The world’s biggest oil and gas companies are turning to unmanned aerial vehicles (UAVs) rather than people, for inspecting and monitoring offshore rigs, pipelines,storage tanks, flare stacks and other infrastructure.
“UAVs are safer and more cost-effective than a lot of inspection techniques that are presently available. They are ideal for inspections in difficult-to-access areas or areas which are unsafe for workers.” says Kayode Adeleke, Senior Executive Vice President of RusselSmith Group, which is also a provider of aerial inspection services.
