Maritime Connectivity Services for Ships and Fleets: The MarineConnect Guide (2026)

What MarineConnect's Maritime Connectivity Services Cover

MarineConnect (MLTECH Marine Connect) provides maritime connectivity services that keep vessels online, under control and visible from shore. In practice that means four layers working together: satellite internet (Starlink Maritime, Eutelsat OneWeb and Inmarsat NexusWave), onboard network management through our SmartBox Gateway, vessel intelligence built on AIoT monitoring and voyage data, and a managed ICT team supporting the whole stack 24/7. We work with fishing fleets, regional cargo operators and ship managers across Singapore, Vietnam, the Philippines and Indonesia. This guide walks through each layer, who it suits and how the pieces fit together, so you know what your vessel actually needs before anyone quotes you hardware.

Key Takeaways:

• Satellite choice follows the route, the crew size and the uptime you must guarantee. Starlink Maritime, OneWeb and NexusWave each fit a different profile.
• A dish is not a vessel network. The SmartBox Gateway adds Multi-WAN failover, crew quotas, firewalling and separate VLANs for business, operations and crew.
• Crew internet access is now an expectation under the 2022 amendments to MLC 2006, in force since December 2024.
• AIoT monitoring, fuel analytics, ABB-powered voyage optimisation and the VMS IoSAT tracker turn connectivity into usable operational data.
• Managed ICT from MarineConnect costs $125 per vessel per month, covering setup, remote configuration, user support and round-the-clock assistance.

Which Satellite Internet Option Is Right for Your Vessel?

The right satellite internet for a vessel depends on where it sails, how many people share the link and how much uptime the operation must guarantee. Starlink Maritime suits most regional fleets on cost and speed, Eutelsat OneWeb adds a second LEO path, and Inmarsat NexusWave fits operators that need bonded, fully managed connectivity with unlimited data.

Starlink Maritime runs on SpaceX's low Earth orbit constellation at roughly 550 km, which is why latency sits far below what GEO VSAT can deliver. For vessels underway we recommend the Flat High Performance (FHP) terminal: a 140° field of view, the highest mobile service tier, and around 25 Mbps up and 250 Mbps down in good conditions. The Standard V4 and Starlink Mini work for coastal boats that return to port often, but they lose reliability in open water. Our guide to Starlink internet for boats and ships covers hardware, data tiers and installation in detail.

Eutelsat OneWeb is a second LEO network, orbiting at about 1,200 km and delivered to ships through Intellian enterprise terminals. We deploy OneWeb either as a primary link or as an independent backup path alongside Starlink, so a single constellation outage never takes the vessel offline. Authorisation for LEO services differs from country to country, which is why we check the vessel's actual route before recommending either network. See our breakdown of OneWeb satellite internet cost, pricing and coverage for current plans.

Inmarsat NexusWave takes a different approach. Instead of switching between links, it bonds GX Ka-band, LEO, coastal LTE (plan dependent) and L-band into one orchestrated connection. Inmarsat offers four plans (Select, Extra, Prime and Advanced) with unlimited data, download speeds up to 230 Mbps on a 1 m GX antenna, and guaranteed speeds from 256/128 kbps up to 2,048/1,024 kbps. If you are weighing it up, start with our explainer on what NexusWave is and how network bonding works.

Most of our deployments end up hybrid. A Vietnamese offshore fishing vessel might run Starlink as the main pipe with LTE near the coast, while a tanker trading through the Straits of Malacca might sit on NexusWave with everything else feeding the same managed network.

How Does Onboard Network Management Work on a Ship?

Onboard network management sits between the satellite terminals and every device on the ship. On MarineConnect deployments, a SmartBox Gateway selects the best internet source, splits traffic into separate VLANs for business, operations, IoT, CCTV and crew, and enforces per-user quotas, so one crew member's streaming session cannot starve the bridge.

The SmartBox Gateway's Multi-WAN engine chooses a gateway by priority or link status, load-balances and fails over between Starlink, OneWeb, GEO VSAT, FleetBroadband and 5G/LTE. Layer 7 application filtering and deep packet inspection (DPI) let operators block or throttle specific apps without touching operational traffic.

Crew access runs through a captive portal with vouchers. Quotas can be set by total data, active time or bandwidth, with reset schedules and automatic disconnection. Alerts fire on whole-vessel usage, per-user usage or any metric you choose. Shore teams manage everything from the admin portal, crew check their own balance and top-ups in a mobile app available in English and Vietnamese, and white-label partners can brand the portal for their own tenants. A built-in billing engine, payment gateway and ticketing system with SLA tracking round it out.

One pattern we see repeatedly on newly connected vessels: without quotas, a handful of off-watch video streams can burn through a monthly data tier in days. Setting limits and alerts on day one is far cheaper than explaining an overage bill later.

Crew connectivity is also a regulatory question now. Under amendments to MLC 2006 agreed through the ILO's Special Tripartite Committee in 2022, shipowners are expected to give seafarers appropriate social connectivity, and those amendments entered into force on 23 December 2024. For port stays and coastal legs, crew can complement ship WiFi with a regional eSIM; our guide to the best eSIM for seafarers and ship crew explains where eSIM helps and where it stops working.

How Are Vessel Networks Protected from Cyber Threats?

Vessel networks are protected by keeping traffic domains apart and inspecting everything that crosses them. MarineConnect designs ships with isolated business, operational technology and crew networks, applies Layer 7 firewall rules and DPI at the SmartBox Gateway, and on NexusWave adds encrypted SD-WAN overlays plus a core firewall operated by Inmarsat.

The regulatory direction is clear. The IMO's maritime cyber risk management guidance expects cyber risks to be handled inside the Safety Management System under the ISM Code. For newbuilds, the IACS unified requirements on cyber resilience, UR E26 and UR E27, apply to ships contracted for construction on or after 1 July 2024, covering both the ship and the onboard systems and equipment.

Segmentation matters because malware moves laterally once it is inside a flat network. If a crew laptop picks up malware, it should never be able to reach an engine monitoring PLC or a bridge workstation. Separate VLANs, strict inter-VLAN rules and controlled remote access paths make that structurally impossible rather than merely unlikely.

NexusWave raises the bar further. Inmarsat describes four protection layers: AES-256 encryption, packet splitting across multiple network paths, DPI filtering and an enterprise firewall at the Inmarsat core that blocks DDoS and inbound threats before traffic reaches the ship. ClassNK has issued a Cyber Security Type Approval confirming the NexusWave onboard architecture meets IACS UR E27 Rev.1.

A connectivity layer does not replace endpoint protection, patching, access control or an incident response plan. When we scope a project with an IT or OT manager, we map existing VLANs, IP-connected OT devices, remote access needs and logging requirements first, then design the network around them.

Vessel Intelligence: AIoT Monitoring, Fuel Data and Voyage Optimisation

Once a vessel is reliably connected, MarineConnect's AIoT platform turns that link into operational insight. Smart tracking combines AIS and GPS for live position, speed and heading, with route playback and geofence alerts for deviations or long idle periods.

A single IoT gateway on the vessel's IoT Bus reads data over industrial protocols, including Modbus TCP/IP, PLC and SCADA interfaces, storing it locally and syncing it to the cloud. Typical data sources include:

• Bridge systems such as ECDIS, radar, GPS, AIS and gyrocompass
• Engine room sensors for temperature, pressure, vibration and RPM
• Fire alarm panels, smoke detectors and bilge level sensors
• Fuel flow meters and generator sensors
• CCTV and thermal cameras for image monitoring and object recognition

Fuel management maps consumption against route, speed and engine status, flags abnormal usage automatically, and lets an integrated AI agent suggest efficiency improvements and generate reports. Dashboards are customised to each vessel's layout and are available on web and mobile.

For voyage planning, we integrate the ABB Vessel Routing API, which optimises routes by speed, fuel, cost or ETA and supports more than 30 configurable safety parameters such as wind, waves, pitch and roll. ABB Marine Weather adds a library of over 500 metocean parameters, updated four times a day at 0.1° resolution.

Fishing fleets get two specific tools. Fishmap Ocean layers a 10-day marine forecast with sea surface and seabed temperature, currents, plankton density and chlorophyll, and uses AI to suggest locations for species such as tuna, scad and squid. The VMS IoSAT tracker sends position and SOS alerts over the Viasat IDP L-band satellite network, with multi-constellation GNSS (GPS, GLONASS, Galileo, BDS), an IP68 housing and 12 to 30 VDC power, and no cellular SIM required. That matters in Vietnam, where fleets working to lift the European Commission's IUU "yellow card" must keep vessel monitoring switched on far beyond mobile coverage. On every IoSAT installation, our technicians confirm a GPS fix and "TX Allowed" satellite status before handing the vessel back.

Managed ICT, Equipment Supply and Onsite Technical Support

Most vessels do not carry an IT engineer, so MarineConnect runs the technical side for them. Our managed ICT service costs $125 per vessel per month and covers system setup, remote configuration, account setup, user support and 24/7 assistance. IoT platform access on web and mobile adds $150 per vessel per month, with an optional one-time fee for localised onboard and remote monitoring setup.

Behind the managed service sits a physical support team. Our technicians handle shipboard installation, retrofits and repairs, with a background in electrical engineering, automation, marine electronics and networking across commercial, fishing and defence vessels. The services cluster includes Onboard IT and Communication Technical Attendant services, Electrical, Navigation and Control System services, and Marine Equipment Supply. On the supply side, we source and integrate satcom equipment from KVH, Intellian, Inmarsat, KNS, Cobham/Sailor, Starlink and OneWeb, plus routers, firewalls, switches and NAS units, through partners in the US, Europe, Japan, Singapore and China.

A typical engagement runs in four stages:

1. Discovery: fleet size, routes, crew numbers, critical applications and the existing antenna, LAN and power setup.
2. Design: satellite mix, SmartBox model, VLAN plan, quota policy and security rules.
3. Installation and acceptance testing: speed, latency, failover behaviour and application checks against agreed criteria.
4. Handover and monitoring: crew portal onboarding, admin access for shore teams and ongoing 24/7 support.

FAQ: Maritime Connectivity Services

What maritime connectivity services does MarineConnect provide?

MarineConnect provides satellite internet, onboard network management, vessel monitoring and managed ICT support as one integrated service. That includes Starlink Maritime, Eutelsat OneWeb and Inmarsat NexusWave deployment, SmartBox Gateway hardware, crew WiFi and quota management, AIoT and fuel monitoring, ABB voyage optimisation, the VMS IoSAT tracker, equipment supply and onsite technical work across Southeast Asia.

How much does managed ICT support cost per vessel?

Managed ICT support from MarineConnect costs $125 per vessel per month. The fee covers system setup, remote configuration, account setup, crew and user support, and 24/7 technical assistance. IoT platform access is an optional add-on at $150 per vessel per month. Satellite airtime and hardware are priced separately, depending on the network and terminal you choose.

Can one ship use Starlink, OneWeb and LTE at the same time?

Yes, one ship can run Starlink, OneWeb, LTE and older links such as GEO VSAT or FleetBroadband together through the SmartBox Gateway's Multi-WAN engine. The gateway selects links by priority or status, balances load and fails over automatically. Operators who want true bonding under a single managed contract can choose Inmarsat NexusWave instead.

Does satellite internet replace GMDSS equipment?

No, satellite internet does not replace GMDSS equipment on vessels that are required to carry it under SOLAS. Starlink, OneWeb and NexusWave improve everyday communication, crew welfare and data transfer, but approved distress and safety systems must remain in place. MarineConnect can advise on how a broadband link fits alongside your vessel's existing safety communications.

Does MarineConnect support fishing vessels in Vietnam and Southeast Asia?

Yes, fishing fleets are a core part of MarineConnect's work in Vietnam and across Southeast Asia. The MMC050 gateway was designed for Starlink-equipped fishing vessels with up to 20 users, Fishmap Ocean supports fishing-ground planning, and the VMS IoSAT tracker keeps vessel monitoring and SOS alerts running over satellite far beyond mobile coverage. The crew app also supports Vietnamese.
