The new £35M Mary Rose Museum in Portsmouth opened to visitors this week.
Consultant Ramboll’s building services engineers oversaw the conservation process during the construction of the new museum.
The Mary Rose was the first warship to be built in England and sank in the Solent during the reign of Henry VIII. It was raised before a worldwide television audience of 60M in 1982. Until 2009 the ship’s hull was displayed in a temporary ship hall. The new museum brings the ship and thousands of objects together under one roof.
The new facility includes a 40m long and three-storey high giant display case to protect the hull and artefacts.
The case’s temperature is maintained at within + or -1C of 19C and within plus or minus 4% of 54% relative humidity, while large amounts of air are used to replicate the thermal weight of a high mass building.
Resilience was also a key issue, and the air handling units include levels of redundancy to ensure the conservation process is robust.
Engineers also worked with the display cabinet manufacturer to develop full-scale mock-up and prototype tests, and achieve the correct microclimates, for the display cases which house the smaller artefacts.
Ramboll initially acted as structural engineer for the Mary Rose Trust, creating the museum’s first design - a steel bridge over the protected dry dock, supported by four, 1.5m piles.
It then monitored the project for the trust when a design & build contract and alternative solution were put in place.
Its engineers and scientists also provided civil engineering, environmental, flood, heritage and transport input for the planning process and building regulation consents.
