TLC for your navaids

More regular basic maintenance can prevent emergency call-outs

More regular basic maintenance can prevent emergency call-outs

John Caskey, Managing Director at Hydrosphere, which supplies and maintains navigational aids has put together the following guide to navaid maintenance.

Typically there are two types of maintenance undertaken by
companies like Hydrosphere: Casualty Response and Planned Maintenance.

The first is something most harbour masters would like to
avoid – an urgent and expensive response to a navigation aid failing for one
reason or another.

The second ‘planned maintenance’ is the preferred option,
delivering long-term savings and helping pre-empt those emergency situations
that can cost so much. But not everyone is doing it…

When budgets are tight it can be difficult to earmark
spending for maintenance. We’re seeing some authorities and harbours pushing
back their maintenance schedules from yearly inspections to two yearly or more,
both for fixed and floating aids to navigation. Many smaller harbours and ports
have no planned maintenance schedule at all, which means call outs are always
an expensive casualty response.

We understand that prioritising spending is tough, but a
proactive rather than reactive approach to maintenance and repair can save you
money in the following ways:

1. Casualty response costs ££££s: If you have recently had
damage to a buoy or a failed light you will know how expensive an urgent repair
or replacement costs. Boat time, man-hours, and parts add up, and costs can
soon exceed a yearly maintenance contract.

2. Pre-empt casualties: Planned maintenance can spot
problems before they develop, such as unreported damage, reducing your casualty

3. Increased lifespan: Regular maintenance can greatly
increase the lifespan of your aid to navigation, power supply and ancillary
equipment, even with long-lasting applications. Saving money on replacements in
the long-term.

4. Monitoring: Regular maintenance can also include
automatic monitoring. Remote monitoring units report back using the GSM network
or satellite and can provide essential information such as the location of a
buoy, battery power and whether a light is working correctly. In many cases
this can pre-empt casualties and allow planned maintenance instead.

Another thing to consider when thinking about the cost of maintenance and
repairs is whether your navigation aids are costing you more than they should.
Yes, your steel buoys may be over 100 years old and still going strong, but
maintaining these legacy aids does not come cheap.

Compare the costs of maintaining a steel buoy compared to a
modern polyethylene equivalent. Instead of bringing them in every few years for
repainting and refurbishing as you do a steel buoy, plastic buoys can be
cleaned and repaired at sea – they don’t rust and no painting is involved.

 Long-term replacing
your legacy navigation aids with new technology could be a very cost effective
solution, reducing your maintenance and repair costs considerably.

 As with navigation
lights, replacing like-for-like is not always the best solution. Advances in
technology mean that there are many new products and options available that
deliver long-term savings, especially in respect to maintenance and repairs.
