The WaMoS Wave Monitoring System
is designed to operate unattended in stand-alone, remote mode.
This document describes 2 real installations of multiple WaMoS
sites with central data collection and distribution. The
examples should give an idea of what is possible. We have a long
time experience in data handling and user requirements. We offer
full service from data source to the presentation.
Helgoland Installation
A WaMoS system is operating on the
German island of Helgoland.

Extreme Wave Monitoring Network in Norway
The WaMoS sites at
the Ekofisk and Norne fields are connected via satellite links
to the shore:
At Ekofisk, a company intranet connects the computers in the
field, sea cables or radio links connect all the platforms to a
LAN (Local Area Network). The center platform has a satellite
link gateway to the onshore base in Tananger, south Norway. From
there the data is forwarded via internet to the
DNMI (Det
Norske Meteorologiske Institutt) in Oslo.
The WaMoS PC has a standard TCP/IP stack and a network adapter
and sends the data with FTP (File Transfer Protocol) directly to
the server in Oslo. Network security is a matter in this set up,
therefore a firewall protects the company intranet from
intruders. The FTP session to Oslo via the Internet is fully
transparent for the WaMoS PC, but it is invisible for users
outside.
The data server in Oslo can be accessed from outside with a
valid user name and password. Clients get the actual data from
here either on demand or with automatic procedures. For example
the OceanWaveS web server gathers the actual Ekofisk WaMoS
data every 20 minutes and provides a graphic output.
The connection to Norne is very similar, with the difference,
that the WaMoS PC has no TCP/IP, but it is integrated into a
NETBIOS network and shares a file system at the central EMS
(Environmental Monitoring System) server. The EMS sends the data
via satellite link to the server in Oslo. Online data from Norne
is available
here.
