What are Telemar TNL
Class Surveys?
A comprehensive radio survey and GMDSS certification service delivered by accredited marine electronics engineers, approved by ABS, Lloyd's Register, Bureau Veritas, DNV, RINA, MCA, Korean Register and NKK. Telemar TNL manages the full survey process, from initial equipment assessment and any required repairs through to flag state coordination and audit-ready documentation, with all survey cycles planned around your port call schedule.
From equipment check to certified and compliant.

What makes Telemar TNL Class Surveys different?
Accredited by all eight major class societies
Telemar TNL's radio surveyors are experienced marine electronics engineers approved by ABS, Lloyd's Register, Bureau Veritas, DNV, RINA, MCA, Korean Register and NKK. This breadth of accreditation means a single Telemar TNL surveyor can complete the survey regardless of your vessel's class society or flag state, no sourcing multiple approved surveyors for a mixed fleet.

Survey scheduling built around your port calls
Survey cycles are planned around your confirmed port call schedule, not the other way around. Telemar TNL tracks upcoming certification obligations across your fleet using the TWS database and identifies the most operationally efficient port window for each survey, giving you maximum advance notice and ensuring there is no unplanned off-hire to accommodate a surveyor's availability.
Equipment assessment and remediation before the inspector arrives
The most expensive survey outcome is a failure at first inspection. Telemar TNL's engineers carry out a full equipment assessment ahead of the survey date, identifying any faults, software issues or non-compliant configurations and resolving them before the class society or flag state inspector boards. First-inspection pass is the objective on every engagement.
GMDSS certification and Accounting Authority services
Telemar TNL is an authorised GMDSS installation and service provider, managing the full certification lifecycle including equipment maintenance, radio surveys, licence renewals and compliance with SOLAS Chapter IV requirements. As an Accounting Authority, Telemar TNL also handles air-time management and GMDSS administration, removing a layer of compliance management that most operators don't have in-house.
Diagnostics, repairs and cable testing, all before survey
Telemar TNL engineers carry out rigorous functional diagnostics of SatCom, radio and GMDSS equipment ahead of every survey, including cable and antenna testing to ensure optimal signal performance. Any faults identified during assessment are resolved by the same engineers, ensuring equipment arrives at the survey date fully operational and correctly configured, with no third-party repair contractors introducing delays or accountability gaps.
Audit-ready documentation, maintained continuously
Every survey, repair, certification and compliance record is maintained in Telemar TNL's TWS fleet database, giving your technical superintendent and DPA access to a complete, up-to-date equipment history and certification log at any time via the customer portal. When a flag state inspection or port state control check demands documentation, it's already prepared and accessible, not assembled under pressure.

operational reliability.
Every vessel depends on bridge systems, navigation equipment and communications infrastructure performing exactly when needed. Telemar TNL helps shipping operators reduce downtime, maintain compliance and improve operational resilience through integrated maritime technology and support services.
SERVICE & MAINTENANCE
Your service partner worldwide
Keeping bridge and navigation systems operational requires more than reactive repairs. It requires reliable support, technical expertise and global coverage whenever and wherever issues arise. Telemar TNL provides planned maintenance, troubleshooting, repairs and onboard technical support through a global service network that helps minimise disruption and maximise vessel availability.
SMART MAINTENANCE
Trusted expertise delivered proactively
Traditional maintenance often begins after operational impact has already occurred. Telemar TNL SMART Maintenance helps operators identify, diagnose and resolve issues earlier through connected diagnostics and remote support. By combining maritime expertise with real-time system visibility, SMART Maintenance helps improve reliability, reduce emergency call-outs and support more efficient maintenance planning.
BRIDGE INTEGRATION
Systems built for you
Telemar TNL designs and integrates bridge systems that align technology, workflows and operational requirements into a seamless environment. From retrofits to newbuild projects, we help operators improve usability, reliability and long-term performance across navigation and communication systems.
CONNECTIVITY
Reliable connectivity
Today's vessels depend on continuous access to operational data, remote support capabilities and business-critical communications. Telemar TNL delivers maritime connectivity solutions that provide secure, resilient communications between vessel and shore, helping operators improve visibility, responsiveness and operational continuity.
IT MANAGED SERVICES
Maritime IT support without the complexity
Managing vessel IT infrastructure across a fleet can place significant demands on technical teams. From onboard networks and hardware management to user support and system performance, maintaining consistency requires specialist expertise. Telemar TNL provides managed IT services designed specifically for maritime environments, helping operators maintain secure, reliable and efficient vessel IT operations both onboard and ashore.
GMDSS
Do you comply to the latest standards?
GMDSS systems play a critical role in vessel safety and regulatory compliance. Telemar TNL provides certified inspections, servicing and maintenance support to help ensure communication systems remain compliant and operational. Our specialists coordinate inspections, certification renewals and ongoing maintenance, helping operators reduce administrative burden while maintaining readiness.
CYBERSECURITY
Protecting your connected systems
As bridge systems become increasingly connected, cybersecurity has become an operational requirement. Navigation systems, ECDIS, radar, communications equipment and bridge networks must be protected against threats that could impact safety and vessel performance.
Telemar TNL delivers maritime-focused OT security services designed specifically for bridge and navigation environments. Our specialists help operators strengthen cyber resilience while maintaining safe and reliable vessel operations.
