Keeping vessels in peak form when laid up in dock
Client: Shipping contractor
Location: Leith, Scotland
Sectors: Shipping
The challenge
Preventing corrosion by controlling temperature and humidity levels
A leading seabed-to-surface engineering, construction and services contractor had to lay up four of its survey ships in Leith Docks.
Salt water and humidity threatened to cause corrosion, condensation and freezing, which would damage the ships and their sensitive technical equipment on board.
Project fact file
The solution
Heat pump chillers and dehumidifiers to pump hot and cold dry air
We installed four heat pump chillers to provide hot and cold air to control the temperature. We also installed 12 desiccant dehumidifiers to produce conditioned, dry air to keep humidity at around 50 per cent. 1 MW of power kept it all going.
The impact
Four ships remained in top condition for future use when needed
By controlling the levels of humidity and temperature, the vessels were kept in tip top condition – no rust or risk of deterioration of the assets – so they could be recommissioned quickly, when needed.
