The containers are small, self-contained setback units (see picture) that are placed horizontally in stacks on the deck of the vessel when not in use.

On board the supply boat and the drilling rig, handling of the containers is done completely hands-free. This leads to a greatly reduced number of incidents and downtime. When its in use for storing, tubular containers can be used to transport other cargo.

The existing riser handling gantry crane is used for handling the containers on the drilling vessel. The containers are transferred from the horizontal deck position to a vertical position after which the tubulars can be picked up by the pipe racking cranes.

A number of containers can be placed next to each other, forming a modular setback facility for the Multy Purpose Tower. On the drillfloor the tubulars are handled by a normal pipe racking crane similar to the crane used with the setback drum arrangement.

The main advantages for the customer are:

• Safer and more reliable stand building
  
• Reduced number of crane lifts on the rig
  
• Increasing safety
  
• Better utilization of crane capacity
  
• Zero manual intervention pipe handling operations
  
• Reduction of wear and tear on the drill pipes, casing or containerized tubing

Huisman-Itrec Container system is designed specifically to increase the efficiency of the drilling operation.

• drill pipe,
  
• drill collars,
  
• casing and other tubulars in lengths of up to 90 ft
