Abstract:
Concrete is the most affordable construction material and the second most consumed man-made product after drinking water, with the versatility to be cast into any shape. Concrete technology has advanced rapidly in recent years and continues to evolve with new developments in construction and materials technology. Early concrete platforms, dating back over 100 years, featured primitive design mixes, materials, and construction techniques. Since then, many concrete platforms have been built, some with poor quality and others with satisfactory performance. Generally, concrete platforms have proven to be more durable compared to steel structures, though they are slower to construct.
In the past 30 years, advancements in concrete and construction technology have ushered in a new era for concrete platforms. Today, owners demand durability designs with lifespans of 100 years or more, and construction times have been significantly reduced. This presentation discusses the durability design of floating concrete platforms, including the recent construction of a 138m x 46m concrete dry dock built for Marisco Ltd, which has a lifting capacity of 9,500 tons. As stationary platforms, concrete platforms offer greater durability, lower costs, enhanced safety, improved stability, and reduced maintenance compared to steel platforms. However, successful execution relies on effective structural and durability design as well as extensive construction experience.
