Lecture Title: Scotland & Japan – Education, Research and Industry Collaboration in Naval Architecture and Ocean Engineering
Abstract: This presentation describes the long-standing collaboration between Scotland and Japan in the fields of naval architecture and ocean engineering, a partnership that spans more than a century. Its origins lie in early transfers of shipbuilding knowledge and the establishment of the Imperial College of Engineering—later the Imperial University of Tokyo—and it has since evolved through sustained programmes of student exchange into contemporary collaborative research in advanced marine technologies and renewable energy systems.
Scottish universities, including Strathclyde, Glasgow, and Edinburgh, have hosted Japanese students and scholars, fostering expertise in hydrodynamics, CFD modelling, and offshore engineering. In parallel, Japanese companies—Marubeni, TEPCO Renewable Power, Sumitomo Electric, and Mitsui—have established a strong presence in Scotland’s offshore wind sector, contributing to project development, infrastructure, and supply-chain capabilities. This dual-track collaboration demonstrates a seamless flow from education and research into practical industry application, supporting Scotland’s transition to renewable energy and advancing knowledge in marine and offshore technologies.

Lecture Title: Reeling, an Efficient Offshore Pipelines Installation Method: Advantages, Technical Challenges and Solutions
Abstract: The reeling installation method involves winding several kilometers of a pipeline on a large diameter reel on shore, and later installing it at an offshore site. The construction and inspection of the line onshore and the relatively fast continuous installation make this method one of the most efficient and, as a result, most competitive for offshore pipelines. At the same time, unlike most other installation methods, the pipeline by necessity is plastically deformed during winding onto and unwinding off the reel, and again as it is bent over the ramp and straightened. The first area of concern is that repeated excursions to plastic strains ranging from 1-3% induce ovality and changes to the mechanical properties that impact the subsequent structural performance of the pipeline. Pipeline discontinuities in wall thickness and yield stress aggravated by repeated plastic deformation can lead to severe local deformation and even buckling. Lüders banding, a material instability that induces discontinuous localized strain of 1.5-3.5% following first yielding, can lead to increased ovality with undulations and in extreme cases to local buckling. Lining a pipeline with a thin layer of a corrosion resistant alloy is a cost effective method of protecting carbon steel pipelines from corrosive hydrocarbons. Lined pipe typically manufactured by hydraulic expansion ends with a light contact pressure between the carrier and liner tubes. Under the significant plastic bending imposed by winding and unwinding a lined pipe onto a reel, the liner detaches from the outer pipe and can develop large amplitude buckles on the compressed side that compromise its structural integrity and the flow. The lecture will discuss the technical issues involved in each of these potential limit states of reeling and ways to remedy each, ensuring the efficacy and vitality of this important installation process.
