Tower Software Overview
General Overview
Tower tailors all software to the requirements/specifications of the client as closely as
possible. Tower software is written for Microsoft Windows XP, Vista, and 7 and
conforms to Windows standards as much as possible. The software is designed to be
totally flexible, configurable, and intuitive. Emphasis is also placed on continuity
between the online and offline systems.
Tower is managed by hydrographic surveyors who have wide ranging experience and
expertise in all the disciplines below ensuring that the application in each case is fully
appreciated and understood, and therefore reflected in the software products and
support.
All software is personalised to the client with their logo and company name displayed.
Tower software covers the following applications:
• Online Navigation Software
� General Navigation
� Civil Engineering
� Ports and Harbours
� Hydrographic Surveying
� Geophysical & Oceanographic Surveys
� Cable Installation & Support
� Dredging
� Pipelay & Tug Management

Online Software Overview
The Tower on-line package is designed to carry out real-time data acquisition from
both surface and underwater sensors and to navigate surface vessels and underwater
vehicles.
Tower software includes a choice of add-on modules for specific tasks and a variety of
utility routines/modules for specialised equipment. There are calibration and data
management routines, geodetic calculations, and other specialised computations.
The software's success is based on its total configurability and ease of use. The
operator does not have to be a Windows expert to get around the software easily
(choice of pull down menus, hotkeys and icons).
Everything about the software is configurable. For example, all I/O's (Inputs &
Outputs from peripheral equipment & sensors, etc), printouts, data logging and screen
formats & layouts are totally designable. Drivers and formats already exist for most
survey peripheral devices and can be easily imported into the system for use, and any
new ones can easily be designed. Due to this total configurability, the software can be
interfaced to any kind and number of peripheral equipment and sensors.
Tower software can be made as simple or as complicated as the user wishes, due to its
flexibility and configurability. For example, screens can be designed to show almost
nothing, or can show everything from survey lines, coastlines, navigational aids,
legend data etc. to colour banded terrain models, charts, CAD drawings, and
GeoTiff's.
The Tower online software currently has the following options:
� Hydrographic/Bathymentric Surveys
� Cable Installation & Support
� Dredging
� Geophysical & Oceanographic
� Pipelay & Tug Management
� Underwater Operations
� ROV Inspection

Online Software
Dredging
This program is designed to carry out real-time data acquisition for dredging
and dredge support operations.
Tower has been involved in the dredging industry since 1990 with Jan de Nul
N.V. and Forth Ports and, more recently, with Dover Harbour Board, Land &
Water, UK Dredging, Detlef Hegemann, Dharti Dredging and Construction,
Dredging Corporation of India, Toa Corporation, and WA Dredging Pty. Tower
specialises in the supply of tailored dredging software and supplies dredging
experienced survey personnel to support the software where required. The
support team at Tower has many years experience both offshore and onshore in
the industry, ensuring that the best possible service is provided.
In addition to the standard features, this program has the following capabilities:
• Dredging progress can be accurately monitored in real time by loading and
displaying a colour banded 3-D model (DTM – Digital Terrain Model) of the
seabed, and updating it from the dredgehead positions.
• Options for trailer dredgers, cutter dredgers, backhoe dredgers/excavators,
ploughs, and cranes.
• A theoretical or ‘design’ model can also be superimposed to enable operators to
assess when the desired datum has been achieved.
• The models can be colour-banded relative to each other, or relative to a local tide
datum, for ease of monitoring.
• The dredgehead positions can be measured and adjusted for tide and draft before
displaying over the model and updating it.
• Profiles can be drawn across and along the track through the dredgeheads, and
will show the following:
� Both actual and theoretical seabed models.
� The vessel in profile.
� The dredgehead positions.
• Specialised cutter-dredger routines allow for spud and cutterhead calculations, and
a transverse profile can be drawn around the curve, which the head will follow.

Dredging (continued)
• Backhoe/excavator routines can interface to Trimble, ScanLaser, or Prolec
systems, or can read from Tower’s own angle sensor system.
• Crane routines can calculate and display XYZ of grab and open/close status, using
Tower’s winch-monitoring system.
• Dredging dump option. Size of dump can be specified and DTM is updated on
icon press or menu click.
• There are checks to ensure the model is updated only when desired.
• Data can be transmitted to other vessels e.g. other dredgers and dump barges, so
all digging and dumping can be seen by everyone, and all vessel positions can be
monitored.
• Multiple tide gauges can be used.
• DXF display routines are available to show soundings and coastline files.
• There are options for network protocol routines to enable the transfer of data
between the Tower Online Dredge software and the IHC/Imtech ECDIS/IMS
system. The system allows for the bi-directional transfer of survey data as well as
the sending of geodetic data, waypoints, digital terrain models (DTM’s) and
volume planes/profiles from the Tower system.
• Other display windows can be added to the screen, such as
� Colour legend.
� Attitude display to compare gyro, course made good and design
heading.
� Histograms for cross-course and position quality.
