 Makai offers sophisticated products that work together to greatly improve the
accuracy and reliability with which submarine cables are laid. We provide:
-
Systems to plan cable installations.
-
Systems to monitor and control in real-time the installation of a cable or
cable system.
-
Systems to analyze in detail the installation of a submarine cable.
The heart of Makai's cable software is a powerful 3-D cable model. This fast,
finite-segment dynamic model was developed by Makai specifically for precise
real-time cable laying control. Having been used successfully prior to and
during numerous critical cable lays, our algorithms have proven to be both
reliable and practical.
All significant factors influencing the position and control of the cable are
included in these programs: full 3-D modeling, complex cables and shapes that
change with time, either 3-D or 2-D bottom terrain and complete current
profiles. Numerous cable types and cable bodies can be incorporated into a
single cable lay or recovery. These programs are suitable for all ocean depths
and cable laying speeds.
Software Suite:
Initially designed in a UNIX operating environment and
operated on HP workstations as the Integrated Control System (ICS) and
Cable Lay
Monitor (CLM), Makai has evolved the software to a Windows, PC-based system. This new suite of cable management software includes:
 |
To
plan
and optimize cable routes & assemblies
Software to create submarine cable routes,
define cables and in-line bodies, edit routes, define and adjust slack,
instantly create an RPL and SLD and estimate costs. Provides common data formats which can be sent over the Internet.
|
 |
To
plan, optimize and simulate cable installations
In addition to the cable planning tasks
associated with MakaiPlan, MakaiPlan Pro allows the user to perform
powerful and precise 3-D, dynamic simulations of a submarine cable
installation. The simulation provided by MakaiPlan Pro gives
a detailed understanding of cable behavior, can be used for training cable
engineers, can be used for pre-lay and post-lay analysis, and can be used
to create a detailed Ship Plan for installation.

 |
Cable lay system
for real-time monitoring of the cable during the lay
3-D dynamic modeling of the cable in suspension to provide
accurate cable touchdown positions and bottom slack or bottom cable
tension and provide instructions
to the cable ship for following the designated Ship Plan. Able to simulate the installation and control of single marine
communication cables before or after an actual lay. Can read a
wide range of digital input data.

 |
Digital Terrain Module (DTM) module for
MakaiPlan™ & MakaiPlan Pro™.
Added module to accurately process and
visualize in 2D and 3D the large amounts of point data collected along an
entire survey area. Colored shaded relief images in conjunction with
detailed color contour maps can be created, automatically geo-referenced and
incorporated in the overall GIS database to further facilitate the
selection of the optimum cable route.
|
|
MakaiSpan module for
MakaiPlan™ & MakaiPlan Pro™.
Cable
and pipeline span analysis software to compute, in near real-time, a
true and accurate representation of the pipe/cable shape on the bottom,
including the free spans, the induced shear and moments along the
pipe/cable as well as the bend radii and reaction forces at the bottom
contact points.
|
 |
Added module for MakaiLay™
to control bottom slack
Allows the at-sea monitoring system to
automatically control bottom slack by controlling cable payout
rate.
|
Qualifications:
Makai's cable lay control development started in 1987 with a
US Department of Energy research program requiring submarine cable placement and
control that was beyond the capabilities of conventional cable laying. That DOE
cable was placed in 1900 meters of water with an average placement error of only
4.7 meters. Since that first highly successful application, the development and
use of Makai's control system have been continuous. The reliability and
robustness of the at-sea software has been demonstrated on many occasions and
the accuracy validated through extensive post-lay surveys.
