Can thermography check a marina's shore power pillars and pontoon distribution?

Yes. Shore power pillars, pontoon feeder boards and the marina’s main switchboard can all be surveyed live with a thermal camera, with nothing switched off. The timing matters most: a pillar only shows a problem while boats are plugged in and drawing current, so survey when berths are full and boats are using power, and record the load at every reading.

Why timing decides the result

A poor connection shows by the heat it gives off while current flows through it (see what load a survey needs). On a marina, that current depends on who is berthed and what they are running:

Summer weekends bring the most boats on the pontoons, with fridges, chargers and air conditioning plugged in.
Winter can be busier than it looks where liveaboards and boats with heaters stay connected.
Visitor berths may be empty midweek, so their pillars carry little or nothing.

Ask the berthing office which pontoons are fullest and when, and plan the route around that rather than a calendar date.

What should be in scope

Intake and main switchboard, and the sub-mains out to each pontoon.
Pontoon feeder pillars and distribution boards, including the connections where cables come down the gangway.
Shore power pedestals: incoming terminals, protective devices and socket connections, opened by the marina’s electrician.
Boatyard supplies: travel hoist, workshop, wash-down and any battery charging.
Fuel berth pump panels, the office, chandlery and any bar or restaurant on site.

Working on the pontoons

Pedestals are small outdoor enclosures, often next to deep water. Panels are opened by the marina’s electrician or maintenance contractor under the marina’s own safe system of work (see who opens the panels), and berth holders don’t lose power. Agree keys, the route and any boats that must not be disturbed before the day.

Traps a good thermographer avoids

Stainless steel, wet surfaces and the water itself reflect heat and sky, and pedestals in afternoon sun warm up from the outside (see outdoor equipment in UK weather). Early morning or an overcast day gives cleaner images, and every reading is taken from inside the opened enclosure, not from the cover. The report compares each connection with a matching one on the same pedestal and gives the difference in °C.

What the marina gets

A report that locates every finding by pontoon, pillar and terminal, with the measured temperature, where it was taken, the difference from the matching reference and the load at the time. Ti Thermal Imaging issues it the same day. Ti inspects and reports; the marina’s electrical contractor investigates findings with the circuit isolated and carries out any work. The same thinking applies afloat (see surveying a ship’s installation at sea).

Why load matters, wherever the equipment is

On a London data centre build, commissioning thermography by our team found 16 busbar sections reading above 80 °C under test load, the highest 103.5 °C at a tap-off unit. They showed because current was flowing. An empty berth’s pillar can’t show you the same thing.

Frequently asked questions

Will berth holders lose power?

No. The survey is done live; nothing is isolated for the camera.

Can every pedestal be surveyed?

Every pedestal can be imaged, but only those with boats drawing power give a meaningful reading. The report says which were under load.

Does it replace the periodic inspection?

No. Thermography finds heat at connections under load; the periodic inspection tests the installation (see does a thermographic survey replace an EICR?).
