COVER STORY- TANK CLEANING No-Man Entry Automated Tank Cleaning Explained, By the Market Leading Technology Supplier Oil and Gas Innovation sits down with Søren Hansen, Chief Sales & Marketing Officer at Oreco A/S based in Vaerloese, Denmark. One of the specialties of Oreco A/S is their “No-man Entry” automated tank cleaning systems which are vastly safer than traditional tank cleaning methods. Two major factors in today’s tank storage world is increasing the need for Oreco´s solutions: Rapidly increasing storage capacity (and therefore increased need for tank cleaning), increased HSE awareness and implementation of more stringent legislation and regulations. We delve into why this method is safer, more efficient, and in the end, cost saving. OGI: Could you start by explaining Oreco’s credentials and experience in terms of the company’s products and services for the Oil and Gas sector? Could you tell our readers the breadth of your experience, how long the company has been active, and its reach? Oreco´s tank cleaning systems have been applied by most of the global oil and gas companies, for example BP, Shell, Exxon Mobile etc. As we speak, more than 1,000 large diameter black oil tanks have been cleaned using Oreco tank cleaning systems. Hansen: The origin of Oreco dates back to 1957, making Oreco one of, if not the one, the oldest tank cleaning systems provider. Over the years, Oreco has developed automatic tank cleaning systems for almost every possible scenario which are available worldwide from Japan to the USA and from Australia to Canada. Quality, safety and environmental protection are key elements in the development and production of Oreco´s tank cleaning systems. Oreco holds a number of certificates of approval from recognised international institutes and government bodies. These cover Oreco cleaning processes and Oreco’s management system as well as our sub- contractors, their products and their production methods. Consequently we have encountered a large range of oils, scenarios and tanks which is in addition to the various national and international rules and regulations that must be observed in order to ensure safe, reliable, predictable and efficient no-man entry automatic tank cleaning operations. OGI: What are some of the issues companies run into in relation to tank cleaning operations? Hansen: Increasingly stringent and complex legislation and regulations have been introduced to focus on operational safety, the minimization of environmental impact and the reduction of health and safety risks for staff. At the same time there is an increasing demand from tank owners all over the world for no-man entry automatic tank cleaning systems performing thorough, efficient, reliable and predictable tank cleaning operations. State-of-the-art, fully integrated closed- loop systems, provided by Oreco, therefore incorporate desludging, washing and cleaning of the tank interior with sludge separation into clean directly reusable oil, disposable water and solids. Despite this, even in the year 2018, after over 100 years since the construction of the first crude oil tanks, hazardous manual cleaning methodology remains a common practice at many sites. Cost is almost always the stated or implied justification by the tank owner’s representative for electing to award tank cleaning contracts to methodologies based on outdated, primitive and hazardous manual cleaning. However, such argument does not stand up to scrutiny, in fact automatic closed loop cleaning is almost always significantly cheaper for the individual sites, especially when factoring in waste disposal, value of recovered product, tank out of service cost etc. Unfortunately, more often than not the cost-rewards from these are assigned to different operational budgets, than the budget assigned for tank cleaning, thus driving a culture for methodology decisions based on individual budgets and not on a more site wide/company-wide holistic view. OGI: What are the benefits of using an automated system opposed to traditional methods? Hansen: Applying automatic no-man entry tank cleaning technology instead of using traditional manual tank cleaning provides the tank owner with some distinct advantages, including the following: • A view a Oreco MoClean®-ATS Automated no-man entry tank cleaning system in operation. Automatic tank cleaning systems are reliable, effective and provide predictable tank cleaning times, which is important to tank owners planning schedules. Tank
