Flexible corrugated pipes as used for the transport of gas in offshore deepwater applications can generate undesired flow-induced pulsations (FLIP). This phenomenon has been also traditionally called “singing risers”. The pulsations generated may result in high-amplitude cyclic stresses in the pipe systems attached to the flexible. Moreover, an...

For measurement of the gas temperature inside process piping, temperature sensors are installed in a thermowell. In most cases these cylindrical thermowells are installed perpendicular to the flow direction. Declining pressures of many aging oil & gas assets results in higher gas velocities. This will increase the so-called Strouhal frequency...

Traditionally ventilation systems in the Netherlands are installed in new or retrofitted buildings by an installation fitter under the responsibility of a contractor. In some cases but certainly not all cases, it is checked by a consultant if the ventilation system performs according to the design. Studies in the Netherlands show that...

The water injection system of an FPSO active in the Gulf of Guinea is to increase injection capacity to levels that are threatening from a flow-induced vibration perspective, such that hydrocarbon recovery can be accelerated. A three-tier method based on the internal guidelines of the system operator has been employed to assess the level of FIV...

Gemotoriseerde tweewielers zijn nog steeds een belangrijke bron van geluidhinder. De Europese voertuiglimieten voor geluid worden herzien, daarom is nu van belang de opties voor aanpak op een rij te zetten. In dit artikel worden de problematiek en handlingsperspectieven belicht.

Prior to subsea installation, a subsea system has to be tested to verify whether it performs in accordance with specifications and component specific performance evaluation criteria. It is important to verify that the assembled components work in accordance with the assumptions and design criteria used in the detailed engineering. These criteria...

Concern exists about the potential effects of pile-driving sounds on fish, but evidence is limited, especially for fish larvae. A device was developed to expose larvae to accurately reproduced pile-driving sounds. Controlled exposure experiments were carried out to examine the lethal effects in common sole larvae. No significant effects were...

High cycle fatigue failure is likely to occur when a rather undamped offshore installation is operated over a long period of time. Especially welded parts are vulnerable to fluctuating stress ranges, if the structural components, such as the small bore side branches, are loaded in resonance. In particular, the welded connections at e.g. tie-in...

This paper describes a novel and advanced tailor-made fatigue assessment method whereby acceptable vibration levels are based on maximum acceptable stress ranges for individual side branches. The acceptable stress ranges for each critical welded connection are based on a fracture mechanics analysis of fatigue crack growth. This method also...

Flexible Risers are prone to the generation of high amplitude tonal noise, i.e. a so-called singing riser. Recently, severe vibrations and high noise levels were encountered on the turret of an FPSO in the Norwegian Sea, resulting in significantly reduced production. The vibrations could be attributed to pulsations generated either by a flexible...

In the oil & gas industry there is a trend towards more subsea activities. To improve gas recovery from existing and new fields at greater depths, the produced gas will be compressed, processed and transported via subsea templates and underwater networks (pipelines, flexible risers, etc.). Besides the huge consequences for the subsea...

In view of the rapid extension of offshore wind farms, there is an urgent need to improve our knowledge on possible adverse effects of underwater sound generated by pile-driving. Mortality and injuries have been observed in fish exposed to loud impulse sounds, but knowledge on the sound levels at which (sub-)lethal effects occur is limited,...

In pipe systems, carrying gas with high velocities, broadband turbulent pulsations can be generated causing strong vibrations and fatigue failure, called Acoustic Fatigue. This occurs at valves with high pressure differences (i.e. chokes), relief valves and obstructions in the flow, such as sharp bends and T-branches. Characteristic for the...

In the EU Green Paper on Future Noise Policy of 1996 it was already concluded that the total effect of EU and Member States legislation on environmental road traffic noise was unsatisfactory until then. This was underpinned by extensive studies in the late nineties in the Netherlands, Germany and other countries. A very recent study in the...

To protect installations in the gas and oil industry and process industries against overpressure the installation of relief systems is common practice. However, there have been incidents where such systems fail as a result of high dynamic loads caused by: the generation of shock waves when the relief valve is opened very instantly; the...
