Impact of box-type floating breakwater on motion response of hydrodynamically coupled floating platforms downstream

Floating breakwaters are applicable in several offshore applications to protect downstream structures from excessive wave loads and to reduce their motion response. This thesis investigates the impact of the leading platform, functionally a breakwater, on the RAOs and response of the platforms behind it in frequency domain. The structures are...

A Combined Breakwaters System: A Wave Attenuation Study on the Combination of Submerged and Floating Breakwaters using REEF3D

Coastal zones have been a dynamic area and most favoured locations utilized for living, leisure, recreational activities, tourism, commerce and many other human activities. Submerged and floating breakwaters have been used as effective systems to protect these zones from wave attack. However, they are only effectively functional if the incident...

Effectiveness of Floating Breakwaters: Wave attenuating floating structures

From previous engineering projects it turned out that it is difficult to determine the transmitted wave height of floating breakwaters without performing physical models or using numerical models. In this thesis it is investigated which steps should be taken during the preliminary design process in order to predict the effectiveness (wave...

Numerical analysis of wave transmission behind floating breakwaters

Floating breakwaters (FBs) have been widely used as an alternative solution to protect coastal sites especially small harbors and certain areas which are not suitable for rubble mound breakwaters. Floating breakwater cannot completely stop the incident wave action. Instead, it attenuates the wave action by partially transmitting, partially...

Feasibility study on the use of a floating breakwater to protect a new artificial beach in Balchik, Bulgaria

The coast of Bulgaria is subject to erosion. Because of this fact, around the town of Balchik, which is situated on the Black Sea coast, almost no sandy beaches are present. Last years there have been vast tourist developments in and around Balchik. Because of these developments, the province demands solutions to adapt coastal protection...

Fieldwork coastal engineering: Preliminary design of a floating marina, Varna, Bulgaria

The beach in front of the hotel Sirius is suffering from a retreating coastline. Bathymetry and beach profiles were measured. With the data from previous years the long term evolution of the coast was analyzed. The main conclusions were that the beach in front of the Sirius hotel is still suffering from erosion and if this erosion trend...

Improving surfing conditions with floating wave filters

The sport of surfing has increased tremendously in popularity in the last decade and surf breaks around the world are progressively getting overcrowded with surfers. This overcrowding is an annoyance to surfers themselves since surfing is an individualistic sport, one wave for one surfer. This coastal problem has been addressed by science...

Zanddiodes voor Delfland: Onderzoek naar de invloed van drijvende Offshore golfbrekers op de Delflandse kust

Onderzoek naar de invloed van drijvende golfbrekers op de kust van Delfland. Om de werking te zien van het zanddiode-principe in te zien, is zowel voor het langstransport als het dwarstransport, een mathematisch model toegepast op de Delflandse kust. Uit de berekeningen van het langstransport kwam naar voren, dat het mogelijk was om het netto...

Vryhof floating breakwater: A Preliminary Study on Wave Attenuation and Mooring Forces, volume 1

A study has been conducted to investigate the wave attenuation characteristics and the mooring forces of a new concept of a floating breakwater concept i n a three-dimensional wave situation with regular waves. A literature study showed that the mooring forces of a floating breakwater in a two dimensional wave situation hardly had been studied....

Service port for Beira harbour, Mozambique

This study for a service port in Beira Harbour can be divided into three different parts. These parts will be discussed below in the sequence in which they have been carried out. The first part consists of the preparations for the journey to Beira and the actual site investigation. In Beira a site investigation had been carried out to obtain all...

Golfhoogteverlaging in het Ekofisk veld: Een alternatief voor de platform jack-up. Deel II

Deel II bevat het derde deelverslag uit maart 1988 waarin de dynamische golfbreker constructief wordt uitgewerkt. En waarin ook een kostenschatting van de dynamische golfbreker in het Ekofisk veld is gemaakt. De dynamische golfbreker is een golfdempingssysteem bestaande uit een groot aantal boeien die onder het zeeoppervlak verankerd worden, en...

Floating breakwaters: Literature review

The purpose of this report is to find out which floating breakwaters can be utilized in open sea conditions and what can be expected of them. Since every breakwater interferes with the energy of the waves, it is logical that a probable power generation function of floating breakwaters is also investigated. This report is a global review of the...
