Expert support in all phases from design to operation and extended lifetime

SHARE:

Cranes and lifting appliances are inherently high-risk equipment, whether operated offshore or onshore. Hence, most countries need strict requirements for design verification, fabrication survey, and witnessing of testing for such equipment. 

Since the 1980s, DNV has assisted operators, rig owners, crane manufacturers and other industry stakeholders in managing risk within a wide range of crane/lifting projects, mainly in the oil and gas industry but also in wind turbine industry, harbours and land-based industry. Our extensive, technical and operational knowledge, and in-depth understanding of standards, allow us to provide cost-effective, multidisciplinary services across geographies.

DNV plays an active role in the development and maintenance of national and international standards such as the establishment of EN 13852-1, the upcoming EN 13852-3 and NORSOK R-002. Additionally, we develop DNV recommended practices, many of them in close cooperation with the industry according to market demands. 

Lifting appliances typically included in DNV’s project portfolio are: 

• Offshore cranes, traverse cranes and winches 
• Lifting appliances in drilling area
• Launching appliances for lifeboats
• Harbour cranes and cranes in wind energy industry
• Lifts for personnel and goods
• Lifting beams and pad eyes.

DNV has expertise within all kinds of technologies used for driving lifting appliances, such as diesel-hydraulic, electro-hydraulic and power electronic.
