Pendennis Shipyard refits and services luxury yachts
About 50 firefighters have tackled a major fire at Falmouth Docks in Cornwall.
Emergency services were called to the blaze at a three-storey building in Pendennis Shipyard at about 0230 GMT.
The fire was contained in a recently refurbished refit building, which included a paint store and spray booth.
No-one was injured, but one person was treated for smoke inhalation. Crews removed roof and side panels in order to get to the first-floor fire.
An investigation into the cause of the fire will begin later.
Divisional Officer Steve Burn from Cornwall Fire Brigade told BBC News crews had to work in arduous conditions.
'Business as usual'
"The type and nature of the work that goes on here obviously caused us some problems and concerns," he said.
"It was a very intense and severe fire - the heat and conditions made it difficult for the crews," Mr Burn said.
Pendennis Shipyard services and refits luxury yachts and the building affected by the fire had been recently refurbished.
The company's managing director said as the fire had been successfully contained to one floor of the building it would be "business as usual".
Queen's Wharf at Falmouth Docks was destroyed by a fire in January 2003.
