The yearly installed percentage of offshore wind jacket substructures is rising. The most common installation method for a jacket structure nowadays starts by driving the foundation piles in the seabed through a pre-piling template. The jacket is then lowered on top until the legs are resting on the foundation piles through friction-based...

The demand for a substantial increase in renewable energy causes the need for more and bigger wind turbines. To counter the problem of available space, windfarms will move into deeper water. The challenge of deeper water in combination with higher turbines, require new developments in the wind industry. The often used monopiles make way for a...

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...

As facilities in the Dutch North Sea are approaching the end of their production life, the focus shifts from the developing to the decommissioning of facilities. The legislation on offshore pipeline decommissioning in the Dutch North Sea is currently unclear. The Minister can decide whether pipelines are to be removed or are allowed in situ. In...

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...

Renewable energy generated by offshore wind turbines (OWT) are nowadays more frequently used in the offshore industry. The design of OWT foundations share similarities with a typical offshore oil and gas construction, however a OWT farm usually consist of multiple foundations whose installation are more cost-sensitive compared to one oil and gas...

Fast growing offshore maintenance work scopes increase the demand for better insights in cost and risk reduction opportunities related to redundant work scope maintenance activities. This report describes the research on developing a structured selection methodology to compare benefits between different strategies on removing or maintaining...

Fixed steel structures in the North Sea that are approaching end of life are increasing in mass and dimensions, this imposes challenges on the current decommissioning strategies. The main challenges arise during removal of the barge-launched substructures. In contrast to the topsides of these large structures the substructures cannot be easily...

There is an increasing interest in using offshore wind turbines in deeper waters. The tension leg platform wind turbine (TLPWT) is seen as a promising concept for this. Low production costs and limited motions give the TLPWT concept both economic and dynamic advantages. Previous studies regarding dynamic analysis of offshore floating wind...

The offshore offloading of oil from spread moored FPSO’s can be performed in multiple ways. Tandem offloading is an offloading principle that is widely used and tandem offloading does not require additional components what is the case with offloading with the use of a remote buoy. However tandem offloading is vulnerable for safety hazards, one...

To meet growing energy demands wind energy has become an important source of energy. In the last decade wind turbines have been installed offshore to accommodate even more wind power. The offshore wind resource is of a better quality, resulting in higher electricity output. On the other hand, the costs of constructing and installing support...

Offshore structures are designed to resist the impact of the extreme wave. Shell EP Projects desires a computer model that is able to simulate the impact of the design wave on gravity based offshore platforms, such as the Sakhalin PA-B platform. Comflow is a numerical model that simulates fluid flow, by solving the Navier-Stokes equations using...
