What you'll learn

  • Block Casting and Yard Management – Plan and organize the blocks yard, cast concrete blocks of varying sizes, track curing, and ensure maximum compressive stren
  • Block Transport and Installation – Safely move blocks to site, use cranes to position them accurately, stack blocks, and maintain correct spacing and segment di
  • Backfill and Gravel Filter Placement – Place backfill rocks and graded gravel behind blocks, maintain slopes, widths, and thickness, and apply geotextiles to pr
  • Loading Tests – Conduct loading tests to simulate real loads, monitor settlements, and confirm maximum foundation and seabed settlement before crown casting.
  • Crown Concrete Works – Prepare formwork, pour and cure the crown concrete, and install embedded components like fenders and bollards, which are part of the grav

Requirements

  • No prior experience is required. This course is suitable for anyone interested in gravity quay wall construction, civil or marine engineering, or practical on-site construction processes. All concepts are explained from the ground up, so beginners and professionals alike can follow along. Basic understanding of construction or engineering terminology can be helpful but is not necessary.

Description

This comprehensive course offers an in-depth guide to the design and implementation of gravity quay walls, a cornerstone of modern port and marine infrastructure. Gravity quay walls are crucial for providing safe and stable berthing facilities for ships while protecting port operations from environmental forces. Whether you are a civil engineer, marine engineer, dredging specialist, or student, this course equips you with both the theoretical understanding and practical skills needed to work effectively with gravity quay walls.

The course covers all critical aspects, starting with the components of a gravity quay wall, including blocks, foundations, crown structures, fenders, and bollards. You will gain insights into material selection and functionality, learning how stones, gravel, and backfill interact to provide structural stability and long-term performance. The step-by-step site implementation process is explained in detail—from dredging the trench and laying the stone mattress to preparing the gravel foundation and installing precast blocks.

Construction techniques are illustrated with practical examples, including the use of barges, cranes, clamp shells, divers, and survey teams in real-world projects. Practical insights bridge the gap between design and execution, helping you anticipate and solve challenges that commonly arise during construction.

By the end of this course, you will be able to confidently explain, plan, and evaluate gravity quay wall projects, understanding both their structural principles and on-site implementation. This course is ideal for students, young professionals, and engineers seeking practical exposure to port construction, offering a clear pathway from theory to practice. No advanced background is required—only curiosity and interest in marine engineering.

Who this course is for:

  • Civil and marine engineers who want a step-by-step understanding of quay wall construction. Construction site managers and supervisors overseeing marine infrastructure projects. Engineering students or recent graduates looking to gain hands-on knowledge of block casting, backfilling, loading tests, and crown concrete works. Technical professionals involved in marine construction, dredging, or port development. Anyone interested in learning the complete process from block casting to crown installation, including best practices for site organization, safety, and quality control. No prior experience is required, making it accessible for beginners while still providing practical insights for professionals.
