Charlie Reith


Senior Subsea Production Systems Engineer, Technical Advisor (Consultant)

Charles (Charlie) has over 35 years experience in marine and subsea engineering. He started his career as a Marine Engineer with Texaco Overseas Tankships in the 70’s after gaining a BSc in Marine Engineering from StrathClyde University, and within 10 years service achieved Chief Engineer (C.Eng.) status.

He then transferred across into subsea engineering with Texaco Upstream North Sea and worked on the FEED Studies Phase of the Highlander subsea production template at Fluor Engineering in London and worked on its design, fabrication to offshore installation in 1985.

He later gained an MSc in Project Management from the University of Aberdeen in 2007 and worked for Vetco Gray, Cameron Offshore & J.P.Kenny (Wood) as a Lead Subsea Engineer and Project Manager.

Founded SeaFlo Consultancy Ltd in 2010 a now well established (SME) as Operations Director, Principal Consultant working for a number of oil & gas operating entities and on International assignments such as Total E&P U.K. Laggan-Tormore long subsea 140km tie-back West of Shetland and other interesting and challenging assignments for Qatar Gas (LNG), Bumi-Armada (Malta) LNG-FSRU, B.P. Caspian Sea Shah Deniz 2, B.P. Angola, Premier Oil Far East, Beach Energy, Australia subsea tie-backs in the Bass Straits and presently Eni-Mellitah OG FEED Joint Venture offshore Libya in the Mediterranean Sea.

Together with setting up a training services division of SeaFlo with recognized, accredited (CPD) modular training via SUT-IMarEST partnership under a business licensing agreement with Canadian software company GRi Simulations.

Techbyte: Digital Twins for subsea to floating production system assets

The purpose and intent of this abstract, is to outline the process of qualification and assuring a Digital Twin for a real subsea, marine floating production system oil and gas asset, or a transitioning energy facility such as floating wind with underwater structures to following DNV’s recommended practice RP-A204.

Digital Twin-Definition
A Digital Twin is a digital representation of a real-world entity or system; The Digital Twin can predict outcomes from scenarios, supporting enhanced business decision making.
Outputs of the digital twin will include predictive maintenance, real-time asset health life cycle data such as the vessels Hull, subsea condition monitoring such as fatigue damage accumulated by the mooring lines. Motions recorded by the Motion Response Unit (MRU) will be converted into stresses in each mooring line using a transfer function approach (transfer function=stress +motion). The relationship between mooring line stresses and floater motions will be determined using a fully coupled global analysis model. This method allows for non-intrusive monitoring of mooring line fatigue, providing justification for longer inspection intervals and life-extension of the mooring line system.
This technology gives you the ability to live in the present, learn from the past, and to predict the future Digital Twins for Oil and Gas Symposium
