50 years experience

RANA was established in 1964 in Marina di Ravenna (Italy) as a small professional diving company to provide geophysical and diving services to the growing offshore Oil & Gas industry in the Mediterranean Sea. In the early 1970s RANA was a pioneer in saturation diving and developed advanced techniques and procedures. Since then RANA has worked all over the globe, especially in the Far East, Middle East and West Africa.

In 2005 RANA began a major development programme, investing in training, equipment purchase and the revision and updating of procedures to meet IMCA and OGP standards. In 2007 RANA became a Contractor member of IMCA.

Since 2009 RANA has become a joint-stock company and, with nearly half a million hours of saturation diving experience, has firmly established its reputation as a reliable and professional partner for any major oil company or contractor.
