Some of our business involves work in the offshore industry.  This can be in offshore construction, such as oil and gas wells and installations, or in salvage operations.  The links below are to some of the companies that are prominent in this field, and some that we have found useful.

Maritime-related software

Offshore survey and positioning software.

EIVA Navipac
Part of an extensive suite of software including survey positioning, tug monitoring and control, multibeam sonar, and data collection modules.
Blue Spider
A recent entry to the market, the Blue Spider suite is intended for multi-vessel use, also making effective use of ubiquitous networks on each vessel to facilitate interfacing of serial connections to any PC on the network.  It also includes the innovative feature of an automated data gateway that can be configured to compress and offload collected data to remote sites.

Offshore companies

Oceanfix International
Now part of the RPS group, Oceanfix provides various land and surveysea surveying services, and also is a well regarded agency for freelance offshore workers.


US Coastguard Navigation Centre
Very useful source for GPS availability data.  You can get emailed updates on GPS availability by subscribing to NANUs - Notice Advisory to Navstar Users and Operational Advisories.  These emails give information on the status and planned maintenance of GPS (Navstar) satellites.
A table showing the current status of the whole GPS constellation is here.
Shipping Guides Ltd
The folk at Shipping Guides Ltd asked us to include a link to them, and we're pleased to do so.  Their products are targetted at commercial operators of ships and look like a worthwhile addition to your almanacs.

Sealand is very pleased to be a supporter of the Open Document Foundation, Linux Mint, and the Lancing and Sompting Churches’ Food Bank.
