Traditionally, ports are located in areas protected by natural shelter. Shelter is needed for the safe mooring of vessels and for the efficient handling of containers and other cargo. Disadvantage of the areas which provide natural shelter is their limiting depth. Due to the increasingly bigger vessels, dredging in ports became inevitable....

In this thesis a model is set up to assess the economic viability of early stage buoyancy design concepts. The main research question is to find out if a versatile design approach to the buoyancy lifting concept, i.e. being able to take on multiple projects, can result in an economical viable solution for decommissioning offshore platform...

Concrete structures in marine environments subject to sea ice interaction are at risk of erosion and damage. Industry is interested in characterizing the ice abrasion phenomenon so that abrasion risk can be managed. The experiments conducted in this work have an exploratory character in order to identify the abrasion phenomenon and qualitatively...

Structural vibrations are a known cause of damage to offshore structures and equipment. A Cutter Suction Dredger (CSD) is a dredge vessel known to vibrate heavily during operation. Primary cause of these vibrations is the cutting process, performed to cut and excavate soil from the seabed. A component prone to damage is the cutter ladder, a...

Since the rise of oil prices in 2007, the difference in gas prices between the US and Europe has increased steadily. The pressure to efficiently produce and maintain gas assets has thus also increased. On top of these external trends, ONEgas strives to be in the top quartile companies in the gas market. The integrated contractor of ONEgas, AJS,...

The world is rapidly embracing networked technology and transitioning into one of hyperconnectivity, a term first coined by social scientists Anabel Quan-Haase and Barry Wellman. Increased connectivity provides benefits such as automation and, remote access and control of networks and equipment, thereby decreasing operational costs. Maritime and...

The high stiffness to weight ratio of fibre reinforced composites have been utilized in improving the performance of various structures conventionally designed using metals. One such application is the gangway of the Ampelmann system used to transfer personnel safely from and to the offshore platform in sea. In the current work, a preliminary...

Monopiles are being used more extensively for offshore wind turbine foundation. Current guidelines on the construction of fixed offshore foundations still base the design of laterally loaded piles in sand on empirical data (p-y curves), originating from the oil and gas industry, from field tests executed in 1974 on 0.61 m diameter piles. However...

De Beers Marine is currently mining diamonds offshore near the Namibian coast (at water depths of 115 - 140 meters), using a vertical batch drill mining system ('Wirth drill"). Previously also continuous seabed crawlers have been used, but this method was discontinued because of unsatisfactory operational performance and recovery of the diamonds...

The subject of this report is the upending of a floating monopile for an offshore wind turbine foundation. This is an assignment of Van Oord Dredging and Marine Contractors BV. An analytical model has been developed to simulate the upending of a monopile in MapleTM, based on the general theoretical principles and the experience of Van Oord. An...

Studies underscore the significant reserve potential of the Arctic region: an estimated 25 percent of potential oil and gas reserves, onshore and offshore, is believed to be located in the Northern Hemispheres Arctic region. Although these areas already have been under consideration for over 30 years, technical difficulties have put a threshold...

Floating wind turbines are becoming fashionable within the Renewable Energy world. In the last years MARIN has been involved in an increasing number of projects for the offshore wind industry. The complete simulation of a full-scale free-floating wind turbine under waves and winds using viscous-flow (Unsteady-Reynolds-Averaged-Navier-Stokes...

Seaweed has been part of human consumption ever since humanity met with the oceans. As technology developed more applications for these macroscopic algae were discovered. Global population increased, technology advanced and people started to understand the lifecycle of seaweed allowing them to cultivate seaweed. Seaweed is currently cultivated...

Calf, I.J. (author)
The out-of-plane bending of offshore mooring chains leads to a rapid deterioration of the chain, ultimately leading to failure in a period that is a fraction of the design-life. The deformation of the contact surface of the chainlinks leads to the interlocking of the link. This in turn causes the chain to behave like a bending beam. The...

Trends in the offshore wind market show that newly installed wind farms move towards deeper waters. Wind turbine generators are currently installed using jack-up vessels, which have a limited operating depth. Installation of wind turbines using a floating vessel is an alternative for the current method, but blade installation is an area which is...

Heerema Marine Contractors is an offshore contractor who specializes in the installation and removal of a range of offshore facilities. This includes the installation of submarine pipelines in excess of 1500 [m] water depth. Higher water depths drive the pipeline designs to increase wall thickness. Another motive to apply a low D/t ratio is to...

Uit de voorstudie is naar voren gekomen, dat een LPG terminal met een gekoelde opslag van 70.000 m.3 in het Westelijk Havengebied van Amsterdam mogelijk moet zijn. Voor de aanvoer van LPG vanuit het Midden-Oosten en Noord-Afrika kan men gebruik maken van LPG tankers met een inhoud van 75.000 m? Dat komt overeen met 50.000 DWT. Vanwege de vele...
