⚡ WHAT HAPPENS IF THE PMS FAILS? ⚡
The real question isn't whether a failure can happen.
The real question is:
Can the vessel still get home safely?

At TESS, our Power Management Systems incorporate dedicated Get Home Safe circuitry that allows operators to manually control generators and breakers if the primary automation system becomes unavailable.
Benefits include:
✅ Continued vessel operation during system failures
✅ Manual generator control capability
✅ Manual breaker operation capability
✅ Increased redundancy
✅ Enhanced crew confidence
✅ Reduced operational risk

Many modern systems focus solely on automation.
We focus on what happens when automation is unavailable.
Because getting home safely is what matters most.

From the docks to the open water, the values we carry into every job reflect what this flag stands for.
Integrity. Craftsmanship. A commitment to doing things right.

Happy Flag Day from our crew to yours.

Shore power is among the most critical components of a vessel's electrical system and one of the most frequently misunderstood.

The transition between shore power and onboard generators requires precise load control and proper configuration within the power management system. When that integration is incomplete or incorrectly set up, every piece of electrical equipment onboard absorbs the consequences.

The results range from brownouts and erratic system behavior to a full deadship condition in the most serious cases.

Correct integration across shore power sources, generators, and power management systems ensures stable, protected operation and removes unnecessary stress from onboard equipment.

TESS supports and integrates leading shore power converter systems, including Magnus, with an emphasis on getting the integration right rather than simply supplying the equipment.
