Tony Concagh


A recognised expert in offshore oil and gas and maritime law, Tony advises a range of industry leaders on new contracts and disputes both in court and in arbitration.

Described by Chambers UK as "totally on the ball and always quick to grasp the situation", he advises on new contracts, commercial disputes and also represents clients in court and arbitration proceedings. He acted on the largest amount ever disputed in a London Maritime Arbitration where his clients successfully defended a US$500 million claim made against them under a drilling contract. 

Disputes for the offshore industry include delay, disruption and cost overruns on high value EPIC projects including pipe laying, platform construction and FPSOs. 

On new projects, Tony is often engaged by clients to assist in the drafting of contracts relating to the offshore industry and has been involved in a wide range of negotiations for all kinds of services in many jurisdictions. 

Tony has direct experience of contracts relating to seismic survey, drilling, OSV and specialist vessels charterparties, subsea and ROV operations, seabed pipeline and cable laying, subsea construction, transportation and installation of offshore structures, FPSO and FSO operations and field and platform decommissioning.

Tony is also often engaged on drafting contracts and dealing with disputes relating to the construction of high value specialist vessels such as drilling rigs, construction vessels and FPSOs. In recent years, his efforts have led his clients to recover tens of millions of dollars from ailing shipyards.

He is very proactive, very resourceful and powerful in arbitrations
