Report on ICDP workshop CONOSC (COring the NOrth Sea Cenozoic)

ICDP workshop COring the NOrth Sea Cenozoic focused on the scientific objectives and the technical aspects of drilling and sampling. Some 55 participants attended the meeting, ranging from climate scientists, drilling engineers, and geophysicists to stratigraphers and public outreach experts. Discussion on the proposed research sharpened the...

Towards a universal scaling for broadband turbulent noise in internal flow devices

An investigation is performed on the scalability of broadband noise sources from separated flows in internal pipe systems. Broadband sources from for example wellhead chokes, bends and valves can potentially excite subsea manifolds through fluid acoustic coupling and fluid structural coupling. The focus of the current work is evaluation and...

Overview on R&D and design activities for the ITER core charge exchange spectroscopy diagnostic system

The ITER core charge exchange recombination spectroscopy (core CXRS) diagnostic system is designed to provide experimental access to various measurement quantities in the ITER core plasma such as ion densities, temperatures and velocities. The implementation of the approved CXRS diagnostic principle on ITER faces significant challenges: First, a...

Optical fiber sensors for medical applications: Practical engineering considerations

The advantages of optical fibers as medical sensors are recognized world wide nowadays. Insensitivity to electromagnetic disturbances and relative small dimensions are the most well known properties. The advantages of fiber optic sensors are especially valuable within environments with high temperatures, aggressive or explosive chemicals, strong...

Applying the concept of network enabled capabilities to incident management in the Netherlands

The application of Incident Management to the Dutch road network suffers from serious problems in terms of availability of accurate and up-to-date information. In this paper we present an approach aimed at diminishing the occurrence of misunderstandings. This approach is based on the concept of network enabled capabilities. This technique allows...

Elimination of flow-induced pulsations and vibrations in a process installation: a combination of on site measurements, calculations and scale modeling

The aim of the work described in this paper was to trace and eliminate vibration sources in a low pressure system with high flow velocities. Considerable vibration on the pipe system between a flashing vessel (6.5 m diameter) and heat-exchangers resulted in fatigue failure, leakage and subsequent shut down of a chemical production plant. As...

The mechanical impact of CO2 injection

The mechanical impact of CO2 injection into a depleted hydrocarbon field or aquifer is caused by changes in the stress field, resulting from changes in the pore pressure and volume of the rock. Mechanical processes can lead to the loss of reservoir and caprock integrity, and the reactivation of existing faults. A geomechanical numerical...
