Delfos, B. (author)
Eight million tons of plastic enters the ocean every year, causing damage to the environment, to human health, and to the economy. Due to rotating currents, called 'Gyres', large quantities of that debris accumulate in five areas around the world. In an attempt to clean up the most polluted area, being the Great Pacific Garbage Patch, Boyan Slat...

The aim of this thesis is to assess the feasibility of an iDL (Intelligent Docklocking system), an automated magnetic mooring system (AMMS), for the transfer of crew from a crew transfer vessel (CVT) to an offshore wind turbine. The study includes an analysis of the operability and an estimation of the design requirements of an iDL for crew...

Van Wijnbergen, S.R. (author)
This study dealt with the problems caused by green water waves, waves that reach so high that significant overflow onto the deck occurs. The most important hazard caused by green water is the direct impact load on deck, threatening equipment, hull structure and personnel. The goal of current green water research is to be able to (better) predict...

The present thesis considers numerical computations of fully nonlinear fluid-structure interaction. The aim of the thesis is to establish a well validated fully nonlinear numerical wave tank for the simulations of complex fluid-structure interaction of moored floating offshore structures. The numerical computations are carried out using the...

Drilling in the complex and rough conditions in the Arctic areas is challenging. The challenges include harsh environmental conditions, spill recovery, high operating cost, relatively high risk, limited choice of drilling units, international (environmental) laws/regulations etc. The existence of recoverable oil and gas resources have been known...

In the summer of 2016 heavy lift transport company TPI will transport a topside from Busan, South Korea to the Gina Krog field in Norway. For this voyage TPI selected their second largest vessel, the TPI Mega Caravan as heavy lift transporter. Since 2010 the Dutch based engineering company Hydrographic and Marine Consultants (HMC) were hired by...

A significant reduction in the levelized cost of electricity is necessary for offshore wind farms to become a competitive energy source. Amongst other methods, overall project cost reduction can be achieved by optimized support structure design. An upcoming trend is the use of `XL monopiles', which provide a cost effective foundation solution...

Dynamic analysis of the stinger hang-off system cable forces using ship motion data of Audacia. Already for some time the desire exists to acquire insight into the phenomenon of stinger uplift. This is the situation where external forces and motions acting on the ship, stinger cause the hang-off cables to have no or barely any cable tension....

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...

The decommissioning market expenditure is expected to grow further in the years to come due to increasing number of platforms that near the end of their production cycle, mainly being xed steel structures (<4,000 [Te]) positioned in shallow waters (30 to 75 [m]). The risks of such operation emerged the need for semi-submersible, heavy-lift...

The Double Slip Joint (DSJ) is a new design to connect the transition piece to the foundation pile of an offshore wind turbine. It potentially offers high dynamic strength and reliability at a lower cost thereby assisting the decrease in cost of wind energy. The design is based on a self-locking principle through vertical settlement of the joint...

The purpose of this thesis is to estimate the required forces for a hydraulic decommissioning cutting tool. The reason for this thesis topic is because of clear regulations and demand according offshore decommissioning. Abandoned offshore structures require to be decommissioned after their lifespan. The low oil prices these days and the pressure...

Suction caissons are used in a variety of bottom founded and floating offshore applications, in shallow and deep waters. The present research focuses on the analysis of suction-assisted installation in sand. Suction pressure measurements from a number of field projects and laboratory centrifuge tests in sandy soils led to find that, in 70% of...

Navigation in extreme cold conditions, means repeated ice breaking in navigation channels and harbour basins. The broken ice resulting from this repeating procedure, is called ‘’ Brash Ice’’, in opposite to ‘’sea ice’’ which is formed statically in calm water. Just after an ice breaking event, caused by a vessel transit, there is a lot of water...
