The offshore industry has numerous needs for fluid transportation during operations. Companies must ensure safety and environmental caution when transporting hazardous fluids. In doing so, it is important that operators use equipment that complies with the latest standards and regulations. Gautheirs’ Offshore Tanks meet IMDG/DOT/ISO/DNV 2.7-1 regulations. The tanks are built in accordance to IMDG(International Maritime Dangerous Goods Code) as well they are in line with all DOT(US Department of Transportation) requirements. The crash frame and base structures are built in accordance to DNV 2.7-1 with some models being ISO approved. The worldwide offshore industry has accepted DNV 2.7-1 as the international standard for offshore CCU’s(Cargo Carrying Units). DNV 2.7-1 was developed by the Norwegian standards organization Det Norske Veritas. DNV 2.7-1 was first published in 1986 and was quickly recognized as the offshore industry standard. The code is a rigorous set of material requirements, manufacturing procedures, and maintenance rules that ensure safe cargo transport in the offshore environment.
