Introduction
System Overview
Neptune 5000 Mk II is the Hea y Duty Cone Penetration system designed and
manufactured by Datem. The system uses the Datem Digital Cone to pro ide
accurate in-situ soil data from the transition zone to water depths up to 3000
metres, and will allow seabed penetration of up to 20 metres.
The system consists of the subsea thruster and frame, illustrated in figure 1, a
topside control box for powering the system and pro iding computer
connection, and Datem’s dedicated PC software for control and data
acquisition.
There are a ariety of optional extras that can be purchased from Datem for
use with this system, but this technical manual only co ers the basic features.
Additional technical manuals are a ailable for the optional features. This

General System Maintenance
When the system is in operation, it should be washed down with clean, salt-
free water whene er it is returned to the deck of the ship. This will reduce
corrosion, and re eal any damage to the frame, pods, compensator, thruster,
or cables.
The electrical cables connected to the sensors, pods, and auxiliary equipment
should be isually inspected regularly to ensure there are no chafes or cuts in
the insulation. The connectors on both ends of the cables should be tightly
fitted with no face gap, and the lock-rings should be finger-tight.
All fastenings should be regularly checked to ensure they are present, tight,
and there is no damage to them or the items they are fitted to.
Reference should be made to the following sections of the manual to fulfil
detailed maintenance requirements, rele ant to each indi idual sub-system
during operation.

Software
Description
The system operation is controlled directly from a Topside computer running
dedicated Neptune 5000 control and data acquisition software. Transmission
from the PC uses either standard RS232 protocol at 19,200 baud or Ethernet.
The data is transmitted to the telemetry system housed in the Topside Control
Box.
Specification
The Neptune 5000 control and acquisition computer software requires a
Personal Computer (PC) that meets the following minimum requirements.
Operational Information
Please refer to the Software manual for information on operating the Control
and Data Acquisition Software.
Maintenance
The only means of maintaining the software is to ensure that the hard dri e
has plenty of space and that running processes on the computer are kept to a
minimum, thus allowing the software to run at maximum speed with no delay.
Remo ing any unwanted applications can be achie ed by na igating to the
computers control panel and then selecting “Add/Remo e Programs”.
It is also good practice to regularly run the Scandisk software (recommended
once e ery month), to ensure that the hard disk is in good condition. Another
recommendation is to ensure that good housekeeping practices are adopted
with regards to file names and locations. This enables the data files from e ery
push job to be located easily and quickly.
