Following great success from the monitoring programmes on board HMS Victory and HMS M.33, Tinytag Plus 2 data loggers have now been installed on HMS Warrior and HMS Trincomalee.
Monitoring temperature and relative
humidity is essential to aiding the
conservation of historic ships and sensitive items
The HMS Victory Conservation Project involves
major work to HMS Victory, Vice-Admiral
Lord Nelson's flagship, to ensure its preservation for the
next fifty years. The conservation project has recently expanded to
include a weather station, situated on the dockside outside the
ship, which allows outdoor conditions to be tracked
alongside conditions on board.
By cross-referencing the data recorded by the loggers with that
recorded by the weather station, Head of
Conservation Diana Davis and her team
have been able to determine that changes in the weather are the
main factor behind long-term environmental patterns on board.
Analysis of the rate of change in conditions internally and
externally has allowed the team to calculate the lag times between
the two, showing how quickly or slowly a change in the weather
affects different areas of the ship. This vital information has
helped the team to identify which areas are the worst
affected by outdoor conditions, and enables them to take
informed action to protect the Victory and its contents.
Tinytag data loggers have also been used on
board HMS M.33, the sole remaining British veteran
of the Dardanelles Campaign of 1915-1916 and the Russian Civil War,
and one of just three British warships from World War I still in
existence. Its metal hull means that interior temperatures can
fluctuate hugely throughout the year - from a high of 51°C in the
summer to a low of -5°C in the winter. Continuous, year-round
monitoring using the Tinytag Plus 2 data
loggers allows quick and predictive responses to damaging
conditions resulting from the extreme temperatures such as
overheating, condensation and damp.
The conservation team were pleased with the performance of the
Tinytag Plus 2 data
loggers on board HMS Victory and HMS
M.33 and have now installed devices on two more ships:
HMS Warrior and HMS Trincomalee.
"The Tinytag temp/RH data loggers we installed on HMS Victory
and HMS M.33 have been very successful in letting us track the
environment within these ships" says Diana Davis. "Since
the Tinytags have been successful on these two ships, we have also
now installed the same model of loggers on HMS Warrior (1860),
aﬂoat here in Portsmouth, and on HMS Trincomalee, at The National
Museum of the Royal Navy Hartlepool, the oldest British sailing
ship still aﬂoat."
The same type of temperature and RH data is being gathered on
board these vessels to track internal conditions. The data
is being used to predict when problems might arise and to inform
the better preservation of the ships and their
