`
`The RCL-3 Remote Cable Leveler is an advanced
`microprocessor-based depth conlrol device which is
`externally mounted onlo a seismic streamer cable. When
`used in coniunction with the CU5-8301 shipboard
`command console. reliable digitally multiplexed
`ship-lo-sensor communications is established.
`
`The RCL-3 provides several operational enhancements
`over previous cable leveler designs. The microprocessor(cid:173)
`based digital feedback system can be optimized for a wide
`range of sea-slate conditions. Depth is measured to an
`accuracy of 1 foot over an operating range of 0 to 200 feet
`and is telemetered back to the ship just as it is for a Remote
`Compass Unit. Cable depth information is thereby
`available for recording onto the header and can serve as an
`excellent check against other depth measuring systems.
`The depth measuring circuitry is autozeroing and requires
`no field calibration. The diving plane angle of the leveler
`is also telemetered to the ship. Valuable cable balance
`information can be obtained from this data as the wing
`angle directly represents the lift and depressive forces
`acting on the cable. An improved aerodynamic wing
`design provides excellent lift characteristics with reduced
`cable noise.
`
`The RCL-3 also keeps the important features of previous
`cable leveler designs. The unique collar mounting
`technique increases operational efficiency by allowing
`fast installation and removal of the leveler on any size
`streamer. A diving plane guard minimizes the risk of
`entanglement with unnerwater obstructions. The stainless
`steel housing protects the leveler from damage in the harsh
`marine environment. The ability to dive the streamer in
`the event of a pending collision with other boats and the
`ability to surface in the event of an abrupt decrease in
`water depth have been kept fast and simple by the use of
`single keystroke commands.
`
`Leveler Operation
`
`The operating depth of the Remote Cable Leveler is con(cid:173)
`trolled by a microprocessor based digital feedback system.
`The operator commands the Remote Cable Levelers indi(cid:173)
`vidually or collectively to the desired depth from the
`CUS-8301 System Controller. A digitally encoded com(cid:173)
`mand signal is transmitted to each leveler and a response
`verifying reception of the correct target depth is expected.
`In the event the response is not received the system will
`continue to retry and flag the improper response to the
`
`operator until all units have correctly responded. There(cid:173)
`after, the depth of the leveler is periodically measured by
`a strain gauge depth sensor and adjustments to its diving
`planes are made by a closed loop servo system to achieve
`the desired depth. In the event a surface command is
`given, all units are commanded to full climb wing posi(cid:173)
`tion. For a dive command all units are commanded to full
`dive wing position until a programmable. preset depth
`is reached.
