Advanced Analysis and Design of Offshore Structures

ABOUT THE COURSE

The course will aim to teach structural modelling of fixed platforms, which includes calculation of
hydrodynamic loading through Morison’s equation. The modelling of the fixed platforms as a 3D structural models, using beam elements will be taught. The response of the structure will be checked using codified rules in order to check the compliance of the structure.

Strength checks for yielding and buckling are dealt with. Fatigue strength checks is also incorporated. .

WHO SHOULD ATTEND

Engineers and scientists involved in the design of offshore structures. Personnel from oil companies, classification societies and offshore structure builders will benefits from attending this course. The course is innovative in both content & structure with a careful balance of theory & practice.

LECTURER CV

Prof Nigel Barltrop

Professor Barltrop is an emeritus professor at the university of Strathclyde, UK and the director of
Barltrop Engineering LLP which was established in 2015 and provides consultancy and expert
witness services in the areas of fatigue and strength of offshore structures, ships, lattice
towers and renewable energy devices. His career activities in different stages are as follows:

2015 – 2017: Expert witness on litigation related to jack up production platforms and an offshore
met mast. Dynamic fatigue analysis of a flare tower and front-end design of a fish farm. Part
time professor at University of Strathclyde.

1995 – 2015: Professor at Glasgow and then Strathclyde Universities. (Head of Department
1995 – 2001). Research work includes Deepwater breaking wave forces and structural reliability of
degrading offshore structures. Published Floating structures: a guide for design and analysis,
MTD/OPL. Expert witness for loss of MV Prestige.

1977 – 1995: Atkins, Head of Marine & Structural Technology department 1984, Technical Director
1988. Projects include design of Leman G platform, Hutton TLP Column-Pontoon
connections, Structural assessment and strengthening of the semi-submersibles Buchan
Alpha and Iolair, the Seacat ‘Great Britain’ catamaran and several tankers, investigation of
damage to WEG MS3 wind turbines. Developed software for analysis of stiffened plating, concrete
offshore structures, coupled tether-hull TLP dynamics and response of lattice towers and
turbines to wind turbulence. Expert witness in relation to losses of Alexander Kielland, Silimna
and Kirki. Published Dynamics of fixed offshore structures (MTD/Butterworth Heinemann) and
Fluid loading on fixed offshore structures (HMSO). Wrote fluid loading section of DEn/HSE
“Guidance notes” and contributed to the development of offshore ISO standards.

1973 – 1977: Freeman Fox and partners, contributed to preliminary design of Hong Kong
mass transit railway, detailed design of Hull “Myton” swing bridge, construction supervision of
Humber suspension bridge.

Mr Trevor Hodgson is in his second spell with Atkins, having been with them in total for well
over thirty years. He has spent the majority of this time working in offshore-related areas, both in the
technical execution of this work and in the management of teams of engineers to achieve
specified goals. He has extensive experience of conceptual and detail design for jacket structures
and topsides, including over thirty platforms in SE Asia, and concrete structures in the North Sea and
worldwide. His experience encompasses both shallow and deeper water platforms of steel and
concrete construction, drilling riser and conductor analysis, semi-submersible and FPSO vessels,
high-speed aluminium surface craft, and even peer review for the nuclear industry. He has recently
been involved in the development of concepts and detailed designs for the offshore renewable energy market, including wind, wave and tidal energy conversion devices, most recently
Wind Turbine Generator (WTG) substructures. He is highly experienced in the application and
interpretation of advanced finite element analysis methods for the design process and has used this
experience to great effect in the development and support of engineering software, primarily the
ASAS: OFFSHORE suite for the oil and gas industry, now part of ANSYS. He is the author of
numerous texts on structural design and analysis, was convenor of a panel covering Structural
Analysis of Fixed Concrete Platforms for the ISO standard on offshore installations, and lectures for
ASRANet and the Universities of Glasgow and Strathclyde on offshore structures and renewables.
