On 29 October 2012 hurricane Sandy hit the coast of New York City. This category 1 hurricane had a devastating effect: large parts of the city were flooded and the city was out of business for several days. An estimated total damage of $41.9 billion had occurred of which $5 billion in account of the metro system. The largest damage was to the...

Wave energy is a promising renewable resource for the extraction of energy. To increase the efficiency of this technology a parabolic reflection wall is located behind a wave farm of heaving point absorber wave energy converters (WECs) to increase the power output of the WEC array by altering the wave field. The WECs are modelled with patches of...

The Houston Metropolitan area is a hurricane prone area and vulnerable to flooding by large storm surges caused by these extreme storm events. The area is a major economic center in the State of Texas and even the whole United States. Protection of the area against flooding is extremely necessary to protect the economy, community and environment...

In the offshore industry rock is used for different kind of applications, such as scour protection and pipeline protection. In deep water operations, but also increasingly in shallow water operations, use is made of the method by guiding the rock from the water surface to the seabed with a fallpipe. During a rock placement operation a current...

Various flood protection measures are studied across the globe, and nature-friendly and environmentally resilient methods are gaining more attention. As part of the building with nature initiative, the project BE SAFE (Bio-Engineering for SAFEty) studies the effects of a vegetated foreshore as a flood protection measure which is found to be very...

In the offshore oil and gas industry, production takes place at more and more remote locations, with Floating Production Storage Offloading units (FPSO’s) often being selected for field development. These units may remain on station during their entire lifetime while operating under adverse weather conditions. Inspections, which have to be...

Traditional reinforced concrete tunnels show limits regarding large spans in the transverse direction. There was a lack of knowledge whether the steel-concrete-steel (SCS) sandwich tunnel can be a solution for tunnels with extreme large spans. Research was needed to understand the structural response of a large span SCS tunnel to the load...

In this report a design tool has been developed for offshore harbours. The main objective of the design tool is to recommend an optimum value for the offshore distance of the berth, the breakwater length and the breakwater type. This recommendation has to be made based on CAPEX and OPEX estimates for the various structures the offshore harbour...

Indonesia has planned to develop 24 main ports to support inter-island maritime highway concept. It has envisioned to balancing the trading activity between the eastern and western part of Indonesia. Nevertheless, trade problem in Indonesia also is caused by inefficient hinterland transportation to/from the port, thus increase transport cost....

The number of wind farms that are commissioned, being installed, or prepared is still increasing due to a growing demand for green energy. To benefit from the higher wind velocities, which can be found at sea, and to prevent the pollution of the horizon, wind farms are being built offshore and installed in an ever increasing water depth. The...

In a world with an increasing energy demand and consciousness of the long-term effects of the use of fossil fuels, offshore industries are continuously searching for new sources of energy. Marine tidal currents, which are a consequence of the gravitational forces exerted by the Moon and the rotation of the Earth, have a theoretical potential up...

In recent years, in a number of projects gate drive mechanisms of navigation locks were checked or adapted for a longer service life, during which the reliability, safety and availability of the structure had to be guaranteed for an extended period. Several problems were encountered. When verifying the gate drive mechanism, it was found that the...

One of the most economically and ecologically important issues related to coastal engineering is the preservation of the coastal areas. The mean to do so, is the good understanding of the sediment transport mechanisms that are involved in the transformation of coasts. In order to protect these valuable areas, man-made structures have been...

Five years ago, the Great Eastern Japan tsunami devastated a large part of Tohoku area (Northeastern Japan), and since then, other coastal areas in Japan have feared the possibility of such a large tsunami. This challenge of reducing flood vulnerability of coastal areas due to tsunamis has been discussed with high importance amongst the...

Shanghai, a metropolis in the east of China, is vulnerable to flooding, and numerous floods have happened along the Huangpu River which flows through the city. In order to protect the booming city and nearly 25 million civilians’ lives and properties, a quantity of flood defences have been built along the Huangpu River. Therefore, a trustworthy...

Liquefaction may have large influence on performance of anchored quay walls and is important to include in seismic design. Design codes provide evaluation methods that provide hardly any insight in the actual development of excess pore pressures and the don’t consider soil structure interaction. There is a need for tools that include these...

In 2002, several mooring chains of Girassol Off-loading buoy which was installed offshore Angola ruptured just after 8 months of service. A new failure mechanism called out-of plane bending(OPB) fatigue in mooring chain links was identified in addition to tension induced fatigue after a series of experiments. Currently, there are no models in...

The present state-of-the-art modelling tools (such as FAST, BLADED) used for modelling an offshore wind turbine (OWT) are too detailed and computationally expensive. These tools are required only at detailed design stages of a project. For the preliminary phase, however, a much simpler (yet reliable) 3D model can improve and speedup the design...

Sheet pile walls are increasingly applied in the Netherlands to reinforce dikes. Up to now it is not known what is the real strength and stiffness behaviour of this sheet pile walls and when the dike with the construction can be considered to have failed. Nowadays an elastic design is applied for reinforcements with sheet pile walls, while for...

The Netherlands are protected against extreme high waters from the sea by an ingenious system of barriers. One of the most famous ones is the Maeslant barrier in the New Waterway near the port of Rotterdam. This barrier however, is subject to discussion, as it might not function as intended, because of the following reasons. It has a very low...
