Howard Doris Engineering Ltd, a joint venture between John Howard Ltd and Doris Engineering of Paris
Established an offshore design engineering (ODE) facility at Loch Kishorn, Scotland to build concrete gravity-base structures for oil and gas production in the North Sea.
1978 The Ninian Central Platform was designed and built by Howard Doris Limited; it was towed out and placed on location for Chevron Petroleum (UK) Ltd in May.
At the time, DORIS Engineering had an exceptional diving division which, alongside ODE, helped Alex McKee salvage The Mary Rose, King Henry VIII's favourite ship.
Later DORIS Engineering became the 100% owner of ODE.
1980s Bibby Line, a shipping company with aspirations to move into the oil and gas industry, bought a 50% interest in ODE from DORIS.
ODE's ownership remained stable for several years until Bibby sold its 50% ownership to Bouygues Offshore, which itself was eventually taken over by Saipem.
ODE is now supported by two equal shareholders, DORIS Engineering and Saipem but remains a fully independent and autonomous engineering contractor.
