Lecture notes CT3330. Introduction, history of caissons, construction of standard caisson, design of standard caisson, construction of pneumatic caissons.

Generating electricity from waves at a breakwater in a moderate wave climate

The purpose of this thesis was to develop a preliminary concept design of a wave energy converter. The type of device designed was limited by several starting points which stipulated, among other criteria, a robust structure which can be constructed within a breakwater and can generate electricity from a fairly mild (in the order of Hs=0.5-1.5m)...

Design of vertical breakwaters

In this book, different types of breakwaters are introduced and their historical development is described in order to understand the advantages and disadvantages associated with each type of breakwater. The failures of breakwaters are then discussed to demonstrate crucial points in their stability design. Finally, the design methods used for...

Proverbs: Probabilistic design tools for vertical breakwaters

Final report and appendices of the European project Proverbs on tools for the design of vertical breakwaters (caisson type breakwaters) and similar hydraulic structures in the coastal zone. It includes the loads (waves) as well as the strength of the structure (geotechnial aspects, structural aspects)

Wave transmission at vertical breakwaters

Recently, interest in vertical breakwaters has grown. The development of ports from natural small harbours to artificial large harbours facing the outer sea has demanded the construction of breakwaters in rougher seas. The vertical breakwater could play a role of importance in this development. To obtain general guidelines for the design of...

Ontwerp van een verplaatsbare caissongolfbreker voor Maasvlakte 2

Voorstudie Om de leidende rol die de haven van Rotterdam in de wereldhandel heeft te kunnen handhaven is het noodzakelijk voor de komende decennia ruimte te creeren in de nabijheid van de haven. Dit kan door het aanleggen van een tweede Maasvlakte, een landaanwinning in zee. Het is mogelijk gebleken deze Maasvlakte 2 technisch, morfologisch,...

The application of spectral analysis in the determination of wave loads on vertical breakwaters

Vertical breakwaters are used in the design of harbours to create a protective area. This protective area can be an approach channel or the harbour itself. Because of large new projects, such as Maasvlakte 11 in the Netherlands and the increasing sizes of ships, many harbours have to be placed in deep water. Deep water requires higher...

Wave impacts on vertical breakwaters

The need for coastal structures, such as breakwaters, at great water depths is rapidly increasing as a result ofthe increasing draught of large vessels and off-shore land reclamations which can, for instance, be used for the benefit of the expansion of harbours and related industrial activities. In water depths greater than approximately 10 m...

Beschouwing van constructiekosten van monoliet golfbrekers

In deze studie zijn voor een fictieve golfbreker lay-out in relatief ondiep water de totale projectkosten tijdens de geplande levensduur van een conventionele stortstenen golfbreker, een caissongolfbreker en een samengestelde golfbreker vergeleken. De totale golfbrekerlengte van deze lay-out is circa 4000 m en strekt zich uit tot in een...

Design Caisson breakwater: An evaluation of the formula of Goda

The growing need for breakwaters in deep water due to the increasing draught of large vessels draws the attention to caisson breakwaters. These monolithic structures are more economical compared to rubble mound breakwaters. Especially in deep water lower construction and maintenance costs and considerable savings in construction time can be...

Mulberry harbour 1944-1994

Overview of the construction of the caissons and the construction of the invasion port at Arromanches in Normandy, France. Includes interviews with the engineers involved.

Breakwater design

Lecture notes on the design of rubble mound and caisson breakwaters.

Recent Italian Experience in the Design and Construction of Vertical Breakwaters

Italy is often considered as a mother country of vertical breakwaters for harbour protection, since they have been widely used all along our coasts long since. An updated location map is given in fig. 1, which also shows the position of the directional wave recording stations of the existing Italian network. The most common vertical breakwaters...
