What Is The Standard For Making Offshore Chemical Tanks?
Chemical tanks used in oil industry are made of tough metal that contains carbon steel
, carbon manganese and micro alloyed steel. Also the metal pots have anti corrosion materials like aluminum so that the pots dont get corroded with salt water or flammable liquid. Making of metal pots is a specialized job done by only a handful of companies. Metal pot manufacturers have to maintain DNV2.7-1/EN12079 standard in their products.
What is DNV2.7-1/EN12079 standard? This certification is issued by classification societies including Lloyds Register and Bureau Veritas. This certificate insures that the product is up to the mark and could be used for offshore supply. Oil firms need to use quality metal pots for carrying poisonous liquids. Only standard containers could carry these liquids safely. Use of substandard metal pots is strictly prohibited as they could spill the liquid in the sea in case of the ship carrying the metal pots meets an accident.
DNV2.7-1/EN12079 standard chemical tanks come at high price and the oil firms should be ready to pay the price. But they could get maximum value for their investment by maintaining their metal pots in good condition. Ideally the oil firms should maintain full stock of metal pots so that they could replace the aging containers. Also they should clean and insulate the pots every time before sea voyage. A quality metal pot could last longer, if it is maintained properly.
Buying metal pots seems an easy job but in reality it is a challenging job for oil companies. There are many manufacturers and this is what makes the job of oil companies more challenging. Oil firm managers have to search many websites to find a reliable supplier. Before starting their search, they have to determine their needs. The managers get a fixed budget for buying containers and they could raise the amount only after consulting their board of directors.
Shopping for chemical tanks with tight budget is really a challenge but there is a silver lining in this dark sky. Some suppliers offer good condition used metal pots at affordable price. Also there are manufacturers that produce standard custom fit containers at no extra cost. Shopping around could help oil firm managers find right supplier but they should be ready to increase their budget with a few hundred dollars.
Oil firms should focus on buying standard chemical tanks and not just metal pots that could melt down after a few sea voyages. An expensive but durable metal pot is much better than an inexpensive but short lived container.
