Company: John Dahle Skipshandel A/S

John Dahle is a supplier and service provider of lifting equipment, fall protection, protective clothing, tools, and other consumer products relevant to the oil and shipping industries.


Ocean Installer is a Norwegian subsea entrepreneur who provides subsea services to the global SURF ( subsea umbilicals, risers, and flowlines) market. Earlier this year, they carried out a complex offshore operation and used a very unconventional method to replace risers (a tube providing temporary extensions for subsea oil wells to a drilling facility on the surface) at the Statoil Visund platform.

“We required a solution which allowed us to replace risers whilst maintaining the Normand Vision construction vessel at a distance of 200 m from the platform.”

Joel Ireland, Project Technical Manager, Ocean Installer AS


“We implemented the Harken SBL snatch blocks and a specialized fiber rope solution to allow safe and efficient transfer of loads over long distances.

The Harken SBL snatch block with fiber rope proved a very robust handling solution whilst enabling excellent ROV handling. We completed this job without incident, and the Harken snatch block and fiber rope solution was a definite part of the success on Normand Vision this year.” Joel Ireland, Project Technical Manager, Ocean Installer AS.

“Harken’s SBL Snatch blocks are the ultimate blocks for power-to-weight efficiency. They are designed for maximum strength at the lightest weight, enabling them to be handled by a single operator. We are delighted that the SBL Snatch block has been an integral part in the success for Normand Vision this year!”
