Module Highlights

Day 1 - A Dive into Catenaries, Bending Stresses, and Reeling Operations

Begin with 'Catenaries,' delving into catenary curves, pipe lay equations, and stresses, accompanied by a practical worked example elucidating control mechanisms through tension. Progress to 'Bending Stresses,' exploring bending dynamics during S-lay operations, break-over length considerations, and challenges posed by concrete-coated pipes within horizontal lay radii. The exploration continues with 'Reeling,' uncovering operations, strain concentration nuances, material qualification essentials, and an insightful worked example illustrating ovalisation and buckling complexities.

Day 2 – Sagbend Buckling, Landfall Strategies, and Barge Stability

Sagbend Buckling' unfolds local buckling criteria and prediction methods within a catenary, offering a worked example illustrating buckle propagation intricacies. Transition to 'Landfall,' where participants explore setup dynamics through a practical example, along with alternative configurations. The exploration concludes with 'Barge Stability,' unravelling the principles of stable floating bodies, methods for determining vessel stability, considerations for free liquid surfaces, suspended loads, and insights derived from a comprehensive worked example.

Day 3 – Dynamics, Lifting Strategies, and Rigging Design Analysis

Dynamics unveils the intricacies of vessel motions, dynamics during pipe-lay operations, essential code criteria, and insights into software applications. A practical worked example provides hands-on experience, followed by output analysis and a comprehensive fatigue assessment. Transition to 'Lifting,' where participants delve into the nuances of static and dynamic loads, lifting operations in air and through wave zones, as well as the intricate processes of lowering through water columns onto the seabed. A practical worked example enriches the learning experience. Conclude with 'Rigging Design and Analysis,' exploring rigging equipment, detailed analysis techniques, and a hands-on worked example.

Day 4 – Lugs, Deck Layouts, Sea Fastenings, Anchors, and Piles

Lugs, Deck Layouts, and Sea Fastenings' unfold the intricacies of lugs and stiffeners, providing a hands-on experience through a practical worked example. Further, participants explore foundations and deck fixings, gaining insights into deck layouts and sea fasteners. Transition to 'Anchors and Piles,' where the program delves into anchor dynamics, pile considerations, and the complexities of sheet pile anchorage, complemented by a comprehensive worked example.
