Ricky Thethi
Global Director, UK

About
Ricky is a Global Director based in 2H's London office having relocated from Houston in 2019 after spending almost 20 years in 2H’s Houston office as part of the management team.
Ricky is responsible for globalising the company’s integrity engineering capability and business across all of its offices in both the oil and gas and offshore wind sectors. One of his current focuses is digital transformation, including the use of machine learning and automation technology to improve the speed and accuracy of structural analysis, integrity monitoring and life extension.
Ricky obtained his degree in civil engineering with first-class honours from the University of Surrey in the UK, and is a fellow and Chartered Marine Engineer of the Institute of Marine Engineering, Science and Technology.

Daniel Reagan
Principal Engineer
About
Daniel has over 17 years experience in deep water equipment design, manufacturing, testing, supply, offshore installation and inspection. As part of his early career roles and responsibilities he conducted global riser analysis, using finite element analysis (FEA) programs such as flexcom, to evaluate the strength and fatigue performance of riser system for major oil and gas operators. In addition to FEA work, spent several years designing, supplying and installing monitoring system for top tensioned riser (TTR’s), steel catenary risers (SCR’s), subsea jumpers and manifolds as well as tensioner systems.
The past 12 years have been spent overseen internal and external equipment design, manufacturing, quality, testing and delivery. Daniel has worked with and travelled to vendors throughout the world evaluating forging, machining and assembly facilities. As well as subsea equipment delivery management he have also been involved in a number of specialty subsea inspection campaign which included the development, testing and offshore inspection of critical subsea infrastructure. He has been the offshore installation lead and been involved with multiple subsea systems working with operators and drilling contractors to install equipment in accordance with procedures and safe working practices.
Expertise
Responsive team of problem-solvers
Our multi-disciplinary engineering and field service personnel have extensive experience in
complex offshore systems and integrity engineering. Because we are independent and know what to look for, we perform assessments quickly and often under extreme deadlines whilst providing unbiased mitigation solutions.
Root cause identification and remediation
We perform forensic engineering in the event of failure incidents to identify root causes, recommend design modifications and deliver remedial solutions. We offer turnkey design and delivery of integrity mitigation solutions using an agile and flexible supply chain cultivated over many years of integrity remediation projects to meet extreme project schedules.
Common issues
Degradation of the riser pipe, coatings or seals
Aircan and buoyancy can leaks and failures
Mechanical connection failures
Leaks due to excessive loading or corrosion
Excessive movement on seabed
