During construction in urban areas often noise and vibrations are not tolerated. For the installation of the foundation piles in these cases there is often chosen for screwed displacement piles. These piles can be installed without nuisance for the vicinity, but do induce large soil displacements during installation. The soil displacements can...

Imagine standing under a load with a weight equivalent to more than 5,000 Tesla’s model X. Panicking is not an option and you need to be fully focused on completing a crucial task. There is no option to leave this precarious situation and your contribution is vital to the success of a multi-million dollar project. Sounds frightening, right?...

Visitors who return from a festival experience an empty feeling combined with fatigue. In this thesis, this experience is called the void. An established psychological phenomenon called the Peak-End rule describes how events are judged by both their peaks, be they positive or negative, and their ends. The end of festivals is now often perceived...

An offshore wind turbine is placed on a so called “foundation” to gain height above the sea surface level. One of the used foundations is the jacket structure, which is kept in place by pre-piled supports. The piles are hammered into the seabed first, after which the jacket legs are stabbed into the piles. A template is used to guide the piles...

Subsea pipeline are extensively used for the transport of hydrocarbons from offshore wells, to platforms, pump stations and to onshore facilities. Because the installation of pipelines is time consuming it is responsible for a significant amount of the total costs of a project. Thus the workability of the installation is of great importance.When...

Scarcity of (green) energy resources drives mankind further offshore and towards deeper waters. Protection of subsea infrastructure is of eminent importance in these environments. The key parameter to have a good control over the installation of rock is the falling time. For larger water depths up to 1200 meters, the accuracy of the falling time...

The offshore wind industry is entering a new level of maturity. Announcements of bigger offshore wind turbines, the interest in new locations for offshore wind farms in harsher environments and the appearance of zero subsidy bids are proof of a rapid development. The next generation turbines are expected to be significantly larger and heavier...

For remote islands with high energy prices in the tropics, Ocean Thermal Energy Conversion (OTEC) can be a reliable energy source to supply a renewable baseload for the energy grid. Also, due to the increasing cooling demand, there is a need for sustainable cooling around the equator. This can be supplied by seawater air-conditioning (SWAC). For...

To plot the roadmap for the oil & gas sector, it is essential to do the market demand analysis and research the influencing mechanism of oil price on the offshore projects market and offshore equipment market. The equipment market of IHC IQIP is primarily the market of offshore structures installation. This project is combing the technology...

The offshore wind market experiences large growth over the last decade. There is a clear trend to installation in deeper waters and to larger wind turbines, to maximize the energy output. The majority of offshore windmills use a monopile foundation, which due to the current trends are getting larger. Seaway Heavy Lifting (SHL) is a company that...

Ever since the late seventies great engineering effort has gone into increasing the fuel efficiency and reduction of the noise profile of aircraft. A concept that has been explored is the wingtip-mounted (pusher) propeller. In all wings energy is lost due to the lift-induced vortex at the wingtip. Wingtip-mounted pusher propellers can recover...

An offshore wind turbine requires a stable support structure to support the tower and nacelle. The support structure in the form of a monopile is lowered to the seabed and hammered in the soil. During the lowering process the monopile may show excessive motions, that occur on an irregular basis. The cause for this is unknown. This thesis is...

Since the oil price collapse at the end of 2014, operators in the offshore industry experience a decline in revenues and a need for downsizing. Simultaneously, the wind industry is growing every year, as an increasing amount of companies and consumers are investing in green energy. This creates opportunities for Heerema Marine Contractors (HMC),...

Subsea rock installation is widely applied in the offshore industry and utilized for a wide range of purposes including but not limited to: pipeline protection, scour protection, insulation of pipelines, upheaval buckling prevention and seabed preparation. Tideway Offshore Solutions is specialized in subsea rock installation and currently...

During S-lay pipeline installation, tension fluctuations in the suspended pipeline are compensated by the tensioner system on the vessel. The goal of this thesis is to answer the questions: to what extent does the active tension compensation (ATC) influence the pipeline integrity during offshore installation. Secondly, which tensioner model...

Offshore Wind Farm (OWF) installation procedure is a complicated phase requiring excellent management of resources for timely completion of tasks. The wind farm installation period involves crucial stages like streamlining onshore logistics, transportation of components on vessels, installation of foundations, wind turbines, and cable laying,...

Loose, sandy slopes situated or deposited under water may be susceptible to liquefaction-induced failure. In contrast to 'regular' localised slope failures, flow slides are diffuse, large-scale and potentially disastrous. Earthquake-induced ground vibrations currently dominate the liquefaction engineering scene. In reality, however, many...

HeeremaMarine Contractors (HMC) owns and operates several semi-submersible crane vessels (SSCV) used for offshore heavy lift operations. Throughout the engineering phase of a (dual crane) heavy lift, dynamic lift models are generated by combining bodies with their hydrodynamic properties, inertia and spring-dashpot elements. The models represent...

Offshore pipelay is the operation of laying a pipe from a surface vessel to the seabed. As the suspended pipe approaches the seabed, it bends downwards forming the sagbend. The sagbend is controlled by the vessel position and a tensile load is applied to counteract the weight of the pipe. During the engineering phase of previous HMC projects,...
