IMPROVISER CLASS I-IV TORQUE TOOL

Fugro-impROV’s ISO 13628-8 Class I - IV IMPROVISER
Subsea Torque Tool offers total versatility, enabling
operation of all common rotary valve overrides and
stab-plate interfaces in a subsea field, in a single dive
without the need for the ROV returning to the surface.
The IMPROVISER contains a unique mechanism which effectively bypasses
the torque multiplier, providing two gearing levels. A hydraulic function is
used to select either the High Speed - Low Torque setting, which couples
the motor output directly to the socket giving a controllable torque output
from 15 to 300 lbf.ft, (20 to 400 Nm), or a Low Speed - High Torque setting External turns count and reset box.
which brings the torque multiplier into line, giving a controllable output from
200 to 2000 lbf.ft, (270 to 2700 Nm).
The torque tool also includes a self adjusting square drive socket that will
automatically select the correct interface drive to suit ISO13628-8 Class I
through to Class IV. The Tool can be supplied with a choice of a paddle /
fishtail / T-bar / ring or vertical deployment handle. The Tool can also be
supplied with a 2 digit external turns count display and ROV mounted reset
switch box when not being used from a control system. An integral digital
turns-count feedback to the topsides control laptop is offered as standard.
An interface kit containing commonly used hoses and a depth compensator
