Long Range Identification Tracking (LRIT) Activation – Global Maritime Compliance with SEANAV
Long Range Identification and Tracking (LRIT) Activation is a mandatory requirement for ships subject to SOLAS regulations. At SEANAV, we specialize in the full activation, testing, and certification of LRIT systems to ensure your vessel remains compliant with international maritime safety and security standards.
LRIT enables the automatic transmission of ship identity and location data to authorized flag states and coastal authorities. It is critical for global tracking, particularly in high-risk or remote zones. Activation of LRIT systems is essential for vessels over 300 gross tonnage engaged on international voyages, including passenger ships and mobile offshore drilling units.

Why LRIT Activation Matters
- Ensures compliance with IMO’s SOLAS V/19-1 regulations
- Allows global positioning and monitoring of vessels
- Supports search and rescue operations
- Improves maritime domain awareness for coastal states
- Mandatory for vessel registration and inspection approvals
