Technical Information

Keep offshore crews safe with dependable communications while achieving enhanced operational efficiency. 

Offshore Energy Solutions

Offshore Energy companies need custom satellite communications solutions that meet the highest levels of network reliability and security for day-to-day business communications and operations. 

AST Networks tailor make [satellite communications solutions](/solutions/bespoke-solutions) to fit as operations expand in scope and duration. You can learn more about how we have helped the world's largest oil and gas companies achieve their goals through our [case studies](/case-studies?sector=5), such as the one below.



Operational efficiency

For crew, being able to contact their loved ones back home and accessing a few home comforts plays a vital role in their wellbeing. Our range of handheld and broadband terminals allow oil rig owners the opportunity to [improve crew welfare](/solutions/crew-welfare) and quality of life by allowing crew to make calls, watch television (TVRO), access the internet and send texts and emails, from any location and in any weather. 

As a responsible partner we are also mindful that bandwidth is managed efficiently. Our [INTEGRA](/solutions/comms-and-bandwidth-management) service gives you the insight to prioritise critical communications and make key bandwidth management decisions backed by automated insights and data. 

Crew welfare

AST Networks tailor make satellite communication-based IoT solutions that provides global asset management and automates machinery. Thanks to our [iRAMS telematics solutions](https://www.ast-networks.com/solutions/maritime-i-o-t-and-asset-management), those managing offshore industry assets can utilise our remote control, fault monitoring and intelligence alerts – allowing preventative maintenance measures and reducing potential downtime.    

Remote asset management

As [OneWeb’s](/solutions/one-web) most experienced maritime partner, AST Networks can provide the industrial grade connections at high-speed and low latency for offshore energy operations. 

The high-performance connectivity allows the implementation of new use cases relying on artificial intelligence (AI), machine learning (ML), and virtual/augmented reality (VR/AR) to revolutionise traditional offshore working practices, enhance processes and improve worker safety. 

Supporting new use cases offshore

We provide satellite communications services which prioritise safety at sea.

Leading the way is the [Lars Thrane LT-3100S GMDSS](https://www.ast-networks.com/products/lt-3100s-gmdss-system) terminal, a truly versatile safety system that not only provides all the required GMDSS distress alerting and voice support but also offers non-safety features in one package.


Iridium GMDSS

LT 3100S Iridium GMDSS System

The LT-3100S GMDSS Terminal from Lars Thrane A/S is the first GMDSS solution to be available for the [Iridium](/en/services/i-1) GMDSS service.  It provides, not only, the key services for GMDSS compliance - such as Distress Alert and Maritime Safety Information (MSI) - but also incorporates non-GMDSS features - non-priority voice, data and SMS - in one small form factor terminal.

 LT-3100S Iridium GMDSS Terminal

Activated by the press of a button, distress alerting sends critical data to the Rescue Coordination Centre (RCC).

Iridium GMDSS Distress Alerting

Connect to an RCC and other maritime authorities through a call to share additional details about the distress situation. 

 Iridium GMDSS Safety Voice

Maritime Safety Information (MSI) is transmitted through and Enhanced Group Call (EGC) service called Iridium SafetyCastSM.

Added Value 

 Establishing a New Standard for Safety at Sea

Inmarsat services and hardware from Cobham's SAILOR mini-C range have been keeping seafarers safe at sea since 1999 when GMDSS was formed by the International Maritime Organisation (IMO). The solutions deliver critical connectivity through the receipt and transmission of vital ship-to-shore and shore-to-ship distress alerts.


Inmarsat-C | GMDSS

Inmarsat-C 25th Anniversary

The Cobham SATCOM SAILOR 6110 mini-C is a true next-generation GMDSS solution.

The SAILOR 6110 mini-C is more than just a way to meet mandatory GMDSS requirements, as part of the innovative SAILOR 6000 Series, it is an integral part of a vessel’s communication system. 

The mini-C system features true triple functionality as it safely handles all GMDSS, SSAS and LRIT operation on board.


Inmarsat-C

Distress alerts are issued when a ship or crew is in imminent danger. When there is no time to input information manually into the terminal, the crew can simply press and hold down the Dedicated Distress Button for approximately five seconds to transmit the alert.

Distress Alerting

Maritime Safety Information (MSI) and Search and Rescue related information is broadcast over the safety terminals, through SafetyNET, SafetyNET II, RescueNET and FleetNET services.

Enhanced Group Calls (EGC)

Short data reports, up to four data packets, that are sent to shore-based authorities or operational centres, such as Long Range Identification and Tracking (LRIT) of ships, as required by the IMO.

Data reporting and Polling

Inmarsat-C is the first-ever approved service that meets the requirements of the International Maritime Organisation’s (IMO) Global Maritime Distress and Safety System (GMDSS) for Ship Security Alert Systems (SSAS).

Certified ship security alert system (SSAS)

You can cruise in confidence that you are compliant with the IMO requirement for Long Range Identification and Tracking (LRIT) for vessel monitoring and polling.

Comply with remote monitoring and tracking


Dependant on the sea area a vessel intends to sail, the minimum requirement of GMDSS equipment will increase the further a vessel goes from the shoreside into remote waters to ensure optimal safety of the vessel and crew.

Maritime Emergency Beacons

Emergency Position Indicating Radio Beacon (EPIRB) equipment provides a portable battery powered emergency locator which is designed specifically to help locate persons or vessels in distress during search and rescue operations. For maritime operations this equipment is a secondary means of distress alerting (i.e. a distress alert needs to have been triggered initially to alert authorities of the distress).

Emergency Position Indicating Radio Beacon (EPIRB)

Search and Rescue Transponder (SART) is a self-contained, waterproof transponder intended for emergency use at sea to locate survival craft or distressed vessel.

Search and Rescue Transponder (SART) 

The minimum global maritime distress safety system (GMDSS) minimum requirement is minimum of two handheld VHF handsets and at least one VHF digital selective calling (DSC) hardware onboard in order to raise a signal should the vessel or crew come into any bother or danger. The further a vessel travels into far-reaching sea areas the more safety at sea equipment is needed.


Safety Radio

Marine very high frequency (VHF) radios enable worldwide communication – the hardware enables two-way radio transceivers on ships and watercraft for voice communication in both ship-to-ship and ship-to-shore environments. 


VHF (handheld)

Digital Selective Calling is a standard for transmitting safety and distress information via MF, HF and VHF. Calling can be between ship to ship, ship to shore or vice versa.

Digital Selective Calling (DSC)

Utilising satellite and terrestrial technology, on-board systems are designed to prevent accidents, quickly alert rescue authorities and nearby vessels in the event of an emergency.

Under the Safety of Life at Sea (SOLAS) convention, cargo ships of 300 gross tonnes and upwards and all passenger ships on international voyages must be equipped with satellite and radio equipment that conforms to international standards. GMDSS systems are equally valuable and increasingly prevalent on 'voluntary fit' vessels such as recreational boats and leisure yachts.

We provide dependable solutions for the maritime industry that enables global connectivity for mariners anywhere in the world. 

From terrestrial radios, GSM handsets to complete GMDSS compliant solutions, AST Networks has the safety of your vessel and crew welfare covered if disaster strikes, and when communication is critical.  


GMDSS Satellite communications solutions for maritime safety, security and efficiency. Services include VSATs, broadband and voice networks for ships, oil and gas rigs and other offshore vessels.
