Shore Based Maintenance (SBM)

The Global Maritime Distress and Safety System (GMDSS) refers to the communications equipment used onboard ship when emergencies strike, as well as the worldwide network of automated emergency communications for ships at sea. The GMDSS is one of the most important pieces of technology on any ship. When a shipowner files a Declaration of Shore-Based Maintenance (SBM), the equipment listed in the declaration is covered by a corresponding agreement recommending that authorized and technically capable companies be responsible for taking care of your GMDSS systems.

Many countries demand that companies offering Shore-Based Maintenance be able to prove that they can provide the services they advertise and contract. The service provider needs to have a recognized quality assurance registration; give 360-day support; have access to OEM for spare equipment; etc.

Tototheo Maritime does all of that and more. We offer SBM for an annual fee to direct all service activities for you; have units available for exchange; take over all communications and service administration expenses; and issue the required certification and paperwork.
