Subsea Retrieval

Safe and efficient recovery of subsea objects.

Operational Challenges

  • Retrieval of objects from the sea floor may cause large forces in the crane and wire due to a combination of vessel movement and suction forces.

Cranemaster Benefits

  • Absorption of forces in crane and wire, preventing direct coupling between load and boom-tip movement.
  • Works as a constant tensioning system, but with added dampening once object is loose from the sea floor.
  • Overload protection during removal.

Overload protection

Cranemaster units will typically be tuned such that it has zero stroke at static weight of the object in water. The stiffness of the system will be varied according to the expected suction forces, while the dampening will be relatively large to absorb rapid release of the object from the sea floor.
