Mary Rose relies on Hanwell’s sensor technology to remain ‘healthy’
H
anwell Solutions has helped preserve one of the most famous tourist attractions in the UK by
developing a temperature and humidity monitoring solution to ensure the correct environmental conditions are constantly maintained for the site.
The 16th century warship Mary Rose sunk in the Solent in 1545. Today, it is in a museum after a 34-year conservation project during which Hanwell’s technology and environmental monitoring sensors played a key role, continuously checking and recording temperature and humidity of the ship during the drying out process, to minimise distortion and the cracking of wood due to environmental fluctuations.
Unique To this day Hanwell’s Pro technology continues to play a crucial role in protecting the historic vessel, recovered from the sea bed in 1982 and brought back to life for the 21st-century visitors. “The Hanwell monitoring system was easy to set up to give us all the data we need. We link it to alarms, which are set so that if one sensor reports an environmental factor has come out of tolerance we can react quickly. The system enables us to get the problem sorted quickly, and helps us with routine maintenance,” said Eleanor Schofield, Head of Conservation and Collections Care at the Mary Rose Trust. Because of the unique nature of the

Over 30 sensors from the Hanwell Pro range are on the hull of the ship, continuously mapping the condition of the wood
Mary Rose, Hanwell had to design a customised solution for the conservation team. The system has been a key indicator in monitoring the drying of the timbers – if something had gone wrong it would have affected the whole ship. Over 30 sensors from the Hanwell
Pro range are on the hull of the ship, continuously mapping the condition of the wood. The Hanwell system not only monitors the ship’s hull, but the vital data is also fed to the BMS system via MODBUS. Data from the wireless sensors also control the separate air- handling units for the collection of artefacts through a Hanwell custom- built MS1000 control panel. Between the two control systems, the critical environmental conditions are maintained between 18-20°C and 50-58% RH. “We continue to experience a good working relationship with Hanwell Solutions and support them when needed. Our need to monitor and control the stability of the environment of course continues, measuring and reacting to how changes in weather, visitor traffic and other parameters affect the ship, so our Hanwell system will continue to be crucially important to the Mary Rose,” said Schofield.
