van Bokhorst, E. (author), Driessen, F.P.G. (author), Nennie, E.D. (author), Remans, D. (author), Smeulers, J.P.M. (author)Caused by the global increase of demand for natural gas the interest in offshore liquefaction, transport and re-gasification grows rapidly. The installations that are presently developed are in essence copies of the onshore systems that are already many years in operation. However, the fact that the installation is installed on a ship imposes...conference paper 2013

Kuipers, W. (author), van Bokhorst, E. (author), Driessen, F.P.G. (author), van den Beemt, C.B.P.J. (author)The LNG Test and Technology Centre (LNG TTC) helps to develop the LNG value chain. It provides a level playing field to equipment suppliers and other stakeholders in the LNG chain to test and qualify equipment and to reduce development barriers. The LNG TTC focuses on strengthening the LNG supply chain and development of LNG as a fuel. This...report 2011

te Raa, L.A. (author), Verhave, J.A. (author), Driessen, F.P.G. (author), Dreschler, J. (author), TNO Defensie en Veiligheid (author)To improve port security capability there is a need for systems for detection, warning and deterrence of unwanted divers in harbour environments. In a complex environment such as a harbour, these topics present challenging problems and as such are subject to research and development. Already a few dedicated systems are commercially available,...conference paper 2010

de Bruijn, A. (author), Benders, F.P.A. (author), Driessen, F.P.G. (author), TNO Defensie en Veiligheid (author)In recent years, TNO has developed a water-filled interferometer, which is able to determine acoustical properties of a sound absorbing material or a compliant layer like the Alberich coating. The frequency range of the measurements is 1.5 to 20 kHz. The main results are mostly in the form of absolute reflection losses of the material mounted...conference paper 2007

(author), TNO Defensie en Veiligheid (author)The underwater acoustics group at TNO Defense, Security and Safety has developed two simulation software programs named ALMOST and SIMONA. The first is already commercially used and aims at sonar performance prediction, whereas the second one is used as a tool to generate simulated data for mine hunting scenarios with the aim to test different...conference paper 2005

Ort, C.M. (author), Driessen, F.P.G. (author), TNO Fysisch en Elektronisch Laboratorium (author)Technological developments concerning underwater systems for Anti Submarine Warfare (ASW) and Mine Counter Measures (MCM) are directed at optimally countering the underwater threat in the near future. Countering the existing underwater threat is already extremely difficult, but there are several trends making it even harder. Therefore it is...article 2002

Driessen, F.P.G. (author), Technisch Physische Dienst TNO - TH (author)With near field imaging techniques the acoustical pressure waves at distances other than the recorded can be calculated. Normally, acquisition on a two dimensional plane is necessary and extrapolation is performed by a Rayleigh integral. A near field single line instead of two dimensional plane acquisition technique is developed for acoustical...conference paper 1995
