Naval Architecture Training


The primary objective of this short course is to provide conversion or refresher training for science and engineering graduates and experienced draughtsmen who hold active line responsibilities in the design of ships and ship systems and in shipbuilding practice. The course is designed in such a way that at the end of the lectures, the person will have a very broad understanding of the behaviour of ships under a variety of loading and operating conditions. The syllabus will include: basic definitions of ships, structural components of the hull girder, general arrangement, ships as functional blocks, hydrostatics & hydrodynamics. The course is intended for practising engineers and research scientists who need to understand the concepts behind the behaviour of ships & ships system at sea.


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

CVs of Lecturers

Ian E Winkle

Ian E Winkle BSc CEng, MRINA recently retired as a Senior Lecturer in the Dept of Naval Architecture & Marine Engineering, Universities of Glasgow & Strathclyde after 26 years involved in Naval Architecture, Ship Design and Ship Production. Before joining the Universities of Glasgow & Strathclyde Mr Winkle worked with Vicker’s Ltd Shipbuilding Group at their Walker Naval Yard and St. Albans Ship Model Experiment Tank before joining Lloyd’s Register of Shipping for a year as a Travelling Scholar. He then spent nearly 4 years working as a Research Officer in the Production Division of the British Ship Research Association, developing new fabrication techniques, before becoming Principal Lecturer in the Dept of Maritime Studies at the Northern Ireland Polytechnic. His areas of research interest include Stability of Damaged Ro-Ro Vessels – most notably the development of the ‘Glasgow Concept’ and the Fabrication of Steel and GRP Ship Structures using Toughened Structural Adhesives, much of which has been undertaken as principal investigator of a range of EPSRC projects.

Professor Purnendu Das

Professor Purnendu Das. BE, ME, PhD, C.Eng, C.MarEng, FRINA, FIStructE, FIMarEST Professor Purnendu Das. BE, ME, PhD, C.Eng, C.MarEng, FRINA, FIStructE, FIMarEST has been the Director of ‘ASRANet Ltd’ since February 2006. He retired as a Professor of Marine Structures in the Department of Naval Architecture & Marine Engineering at the University of Strathclyde, UK in September 2011. Past EU projects were MARSTRUCT (a network of excellence on Marine Structure) and SHIPDISMANTL (a cost effective and environmentally friendly dismantling of ship structures). Past industrial projects included work from the UK Health and Safety Executive (HSE), MoD UK, Subsea-7 UK, Shell, Woodgroup and US Navies etc. He was the principal investigator of many EPSRC projects. Before joining the University of Glasgow in 1991 he worked with British Maritime Technology as Principal Structural Engineer (1984-91). He is the author of more than 250 publications, including contract reports and more than 60 journal papers and is a member of the editorial boards of the ‘Journal of Marine Structures’, ‘Journal of Ocean and Ship Technology’ and ‘Journal of Ocean and Climate System’ and the Journal of Ship Mechanics amongst others. His areas of research include limit state design and analysis & reliability analysis of ship & offshore structures. Purnendu Das has wide ranging industrial and academic contacts and
has advised and supervised 20 PhD students, to his credit. Details of visits and collaborations include his various sabbatical study periods spent at University of California, Berkeley, USA (July – September 1996), at Lloyd’s Register of Shipping (August 1997), Kockums Ltd (July 1998) and spent some time at Instituto Superior Técnico (IST), Lisbon (July 2000). He is running about 20 CPD courses which are attracting many people from different industries. These courses are on ‘Fatigue & Fracture Analysis’, ‘Ships at Sea’, ‘Advanced Analysis and Design of Offshore Structures’, ‘Offshore Floating System Design’, ‘Structural Response under Fire and Blast Loading’ and ‘Design of Pipelines and Risers’ amongst others. He was a member of ISSC (International Ship and Offshore Structure Congress) for the periods of 1991-97 and 2003-2006. He was a member of the OMAE (Offshore Mechanics and Arctic Engineering) Organising Committee on ‘Safety and Reliability’. He is running about 15 biannual international conferences on various themes like Risk, Reliability, Advanced Analysis & Design of Engineering Structures, including marine structures. He was a member of the “Research Committee” of Structural Engineers (IStructE) during 2012-2015. He was a visiting Professor at IST Surabaya, Indonesia from July 2015 for oneyear. He is now a visiting professor at the university of Montenegro, Montenegro and University of Stavanger, Norway.
