CABLE LAY EQUIPMENT SOLUTIONS SMD bring years of knowledge and experience to the design and manufacture of Cable Lay equipment
solutions. SMD can provide bespoke solutions tailored to specific customer requirements
incorporating a range of equipment including Linear Cable Engines (LCE’s), self-fleeting Cable Drum
Engines (CDE’s), Knife fleeting Drum Engine (KDE’s) Draw-Off/Hold Back Cable Engines (DOHB’s),
Diverters, Cable Transporters, together with a fully integrated SMD Cable Lay control system. The Cable
lay equipment can be provided with electric or hydraulic drive systems.
CABLE LAY CONTROL SYSTEM SMD Cable Lay systems can be supplied with an ergonomically designed operator control console. PC based control
with cable deck and bridge mounted control options and video display system can also be provided. Cable
parameter monitoring, logging and alarm facilities can also be incorporated to provide a fully integrated cable lay
control system. Auto seabed slack control of cable engines can be provided by 3rd party cable management
software (e.g. Makai / Racal).
CONTROL SYSTEM FEATURES
PC Based control system
Ergonomic operator console.
Video monitor array options.
Cable parameter logging and alarms.

LINEAR CABLE ENGINES SMD can offer a range of standard hydraulic or servo driven Linear Cable Engine (LCE) systems, the systems
are available with a broad range of ancillary equipment and software to give a comprehensive cable lay
solution. The servo motor driven system achieves unparalleled control and flexibility, with permanent
magnet servo motors to produce a high torque which are able to stall at full torque for long periods
without generating excessive heat. Motors are lower noise compared with induction motors and are
water cooled, requiring no external cooling fan, making it more suitable for operation in high ambient
temperatures. Due to the increased torque, servo motors are able to run at 2/3 of an induction motor
speed to produce the same power, producing proportionately less heat through churning losses in the
gearbox. The servo motor is also shorter and approximately half the mass when compared to an equivalent
power induction motor, which significantly reduces shock loading on repeaters if handled at any speed.
LCE FEATURES
Low mass/inertia guides
Wheel arm geometry minimises
repeater impact loads when
laying
Drives provide excellent anti-slip
and load sharing performance
Repeater handling mode to auto
sequence guide opening ahead of
repeaters.
Modular design to suit Customer
requirements.

CABLE DRUM ENGINES SMD can offer a range of Cable Drum Engines (CDE’s) including a unique knife-free Self-Fleeting Drum,
which incorporates multiple drum staves which translate independently allowing the cable to travel across
the drum automatically. The staves motion is controlled by electric drives giving flexible cable spacing,
ideal for operations with large diameter repeaters. Elimination of cable knives increases the lay speed and
reduces the opportunity for cable damage during lay operations especially for large diameter power cables
and together with multiple wraps, large cable tensions are achievable. Drum engine designs are lower
weight compared to equivalent designs and are suitable for both cable laying and repair operations.
Designs include variable speed AC transmission with integral hydraulic service pack and hydraulic drive
transmission options. SMD CDE’s have reduced rolling resistance compared with conventional drum
engines, which improve slow speed control and low tension render performance.
CDE FEATURES
Knife-free self-fleeting drum design
available.
Safe fleeting system simplifies drum
operation when handling repeaters.
Infinitely variable fleeting pitch to

DRAW OFF / HOLD BACK CABLE ENGINE SMD can offer a range of Draw-Off / Hold-back (DOHB) Cable Engines that incorporate AC servo motor
driven system for unparalleled control and flexibility, providing excellent anti-slip cable handling
performance. The SMD design DOHB uses a 4-wheel pair layout with stretched centre section providing
easy repeater handling. Vertical and horizontal guide and wheel arm design avoids potential shackle traps.
The design also includes an integral sub-frame containing cable engine traversing guidance and actuation
system.
