GEO T RIGGING PROCEDURE Page 19/67
GEO T angle sequences follow logarithmic scales. Angle setting values are:
• Bumper to GEO T4805 : 0°
• GEO T4805 to GEO T4805: 0.125° - 0.20° - 0.315° - 0.50° - 0.80° - 1.25° - 2.0° - 3.15° - 5.0°
• GEO T4805 to GEO T2815: 6.30° - 8.00° - 10.0°
• GEO T2815 to GEO T2815: 6.30° - 8.00° - 10.0° - 12.5° - 15°
The GEO T rigging system has two operating modes:
• Tension
mode: the force of gravity sets angles between upper and lower cabinets. When the
array is lifted into position each cabinet opens automatically to the correct angle.
• Compression
mode: pull-back force applied between the extreme bottom cabinet and the top
bumper set angles between cabinets. When the array is lifted into position all cabinets are at 0°
and it is only when the pull-up force is applied that the correct angles are obtained. Compression
mode can be applied either with articulated kelping beam (“Compression Mode – Full Kelping
Beam”) or with fix beam and chain lever hoist (“Compression Mode – Half Kelping Beam”).
TENSION MODE COMPRESSION MODE
4.3 “Tension Mode” Setup
Tension mode is restricted to small bumper initial angle settings (+/-
~10°, depending on configuration), and does not require any other
accessory than the GEO T bumper (GEOT-BUMPER).
In order to increase initial angle settings to +/- ~15° (depending on
configuration), GEO T bumper can be connected to front beam of
GEO T Kelping Beam (GEOT-KELPBEAM).
