Kosanunt, P. (author)
In recent times, the oil and gas business has moved into unconventional reservoirs, especially in deep-water. One high-potential prospect was found in the deep-water area of Myanmar. A subsea production system pilot project is planned for implementation in this area. One essential element of a subsea system is a “subsea jumper”. The main...

Floating structures as spar, semi-submersibles and TLP have been proposed for offshore wind turbines for deep waters (>60m) according to the report of Arapogianni, Moccia, Williams, & Phillips (2011), where bottom fixed sub-structures are technically and economically not feasible. Several floating concepts have been designed and just some of...

People are already living on water for centuries in some places around the world. However, the concept of building on water has been reintroduced with a new idea in the last two decades. The new idea is to realise a very large floating structure which is as big as a city. Instead of multiple independent floating houses forming a floating...

Hazar Port is located in Turkmenistan on Cheleken Peninsula, which is situated on the eastern coast of the Caspian Sea. Dragon Oil, an international oil and gas exploration company, is engaged in exploration and exploitation of oil and gas in the Caspian Sea. Dragon Oil would like to use the harbour of Hazar as supply base for the expanding of...

The frequency of hurricanes along any 80 km segment of the Coast of Texas is about 1 in 6 years (Roth,2009). On average, 4 major hurricanes (category 3 or higher) occur every century in the Houston-Galveston Region (Needham and Keim, 2011). In addition, the region is very vulnerable: Houston is the fourth biggest city in the US, over 6 million...

This report focuses on a feasibility study of a device that harvests electricity from the vertical motion of pontoons in tidal waves. The study includes an overall look into tidal prediction through laser satellite altimetry and converts the ocean based data of these models into near shore approximations. Furthermore the report compares several...

De Greef, J. (author)
In the province of Groningen in recent years strong induced earthquakes are observed, during which a lot of energy is released in the form of seismic waves. These ultimately lead to horizontal ground accelerations at the ground surface, which affect amongst other things the stability of embankments. The main question to be answered in this...

Aquatic vegetation, found in coastal waters and inter tidal areas, has important features for hydraulic engineering solutions, including sedimentation and stabilization of the bed. The increasing demand to predict wave hydrodynamics with aquatic vegetation asks for insight in the mechanisms and improved model methods. Striving to a more...

Ports are civil works which have a major societal and economic importance. Quay structures are infrastructural elements of primary significance for the functioning of a port system. The ability to economically design quay structures with sufficient seismic resistance is therefore of great importance when situated in areas that are prone to...

The offshore wind industry is a growing market in Europe due to the sustainable energy targets of European Union. In the coming years the Dutch government will invest in offshore wind farms at the North Sea. For a contractor like Boskalis the inclusion of favorable ecological conditions in designs is a unique selling point and can help to win...

A large part of the flood defences in The Netherlands does not meet the present safety standards. In 2014 the delta programme has proposed new safety standards, which are based on the flood risk approach. These new safety standards will for a lot of river dikes be stricter than the currently prevailing safety standards. A lot of work has to be...

Commandeur, A.S. (author)
Turbidity currents are major transport agents in reservoirs in which high concentrations of fine sediments flow in. Reservoir sedimentation due to turbidity currents is often severe in these cases. Turbidity currents are not well understood due to their complex turbulent flow structure, the interaction between the flow with the particles and the...

As the shipping industry is growing, more and more propulsion systems are being developed with better propulsion capabilities. These current and newly developing systems in ships are expected to cause scour at beds around berthing structures with greater likelihood than the systems preceding them, which increases the importance of protection...

The response of longshore sediment transport to the morphodynamic state of the beach was assessed with the use of the process based numerical model, Delft 3D. For this purpose, idealized simulation bathymetries that reflect morphological characteristics of two different beach states (namely longshore bar and trough and transverse bar and rip)...

Mangroves have been proven to be an asset to coastlines because of their myriad advantages relating to coastal protection and stability. Unfortunately, in the past, due to economic necessities or other reasons, many of these mangrove swamps in tropical areas came under threat and were subsequently destroyed. As the awareness about the positive...

The rivers in the South-West of The Netherlands flow over an erosion-resistant bed, consisting of peat and clay, overlying non-cohesive sediments. As they are experiencing general incision, the erosion resistant layer becomes thinner and sometimes locally breaks, exposing the more easily eroded non-cohesive sediments. Consequently sudden scour...

In the coming decades, the offshore decommissioning industry is becoming a quickly growing market, especially at the North Sea, where most offshore platforms have operated for more than twenty years. There is little room for the mistake in the offshore decommissioning operation, therefore the motion response analysis is essential to avoid the...

When designing a rubble mound breakwater, one would like to predict the stability of the armour layer of the breakwater. For this purpose several armour layer stability formula are developed. The most reliable is considered to be the stability formula of Van der Meer (1988). With this method, the armour layer stability is predicted based on...

Controlling the distribution of water and sediment at river bifurcations is one of the main challenges in river engineering and management. This distribution affects the stability of river bifurcations as well as the distribution of flooding risk, navigability and environmental conditions. The governing factors are the hydrodynamics of the two...
