... to employ penetrometers of varying mass and size, to achieve penetration into the seafloor by 15 m or more. The FFCPT can be operated in stationary or moving vessel mode, with the latter method allowing the survey vessel to maintain a speed of up to 8 knots. Interpretation of FFCPT data requires careful...

... are often used in pipeline analyses, despite the complexity of estimating the total restraint. This paper introduces various testing approaches and penetrometer tools – including pipes, toroids, rings and plates – used to characterise this interface behaviour. Centrifuge modelling using field samples...

... the deepest test was a DMT down to 26.4 m below the seabed. The paper describes the equipment, setup and test procedure adopted for this project, employing a seabed penetrometer (Manta), CPTU and Medusa DMT testing equipment. 1 Introduction to DMT and SDMT 1.1 General introduction For over 70 years...

... ABSTRACT: Ball penetrometers are used to measure the undrained shear strength of clayey soils. When the ball penetrometer penetrates the soil from shallow to deep embedment, the flow mechanism of the soil around the ball evolves from the ‘shallow cavity’ mechanism to the ‘deep full-flow...

... ABSTRACT This paper presents the results of extensive full-flow penetrometer testing conducted at the Bothkennar soft clay research site. The results of in situ penetration tests are compared to field vane tests and laboratory data obtained from high quality Laval and Sherbrooke block samples...

... ABSTRACT In most offshore design projects, in situ penetrometer tests are first correlated with element test data in order to assess a suitable resistance factor, so that effectively the absolute value of penetration resistance is not used directly. However, given the difficulty in obtaining...

... penetrometer to assess spudcan penetration in two-layered soil, additional effects such as normalised spudcan level to the soil interface and soil wedge trapped underneath the spudcan base require in-depth investigation. Based on some preliminary results of spudcan penetration tests performed in different...

In recent years, full flow penetrometers, which were initially developed for soil characterisation in centrifuge testing5, have started to be used quite widely as one of the site in- vestigation tools for deepwater soft soil...
