Bearing Capacity of Monopile Comprises of end Bearing Resistance and Shaft Skin Friction. The Design Guidelines for Monopiles are Based on the Standard p-y Method of American Petroleum Institute [7]. Many Researchers Have Shown Through Finite Element Analyses That the standard p-y method overestimates the pile soil- stiffness of large diameter monopiles at great depths which may result in an insufficient pile length. If possible, piles should be driven to their full design penetration without the need to weld-on additional pile lengths, to drive insert piles, or to clean out the soil plug or drill below the initial refusal level of an open-ended tubular pile. [8] gave an example of times required for welding add-on lengths of 1.37 m OD tubular piles; they varied from 3 1⁄4 hours for 25 mm wall thickness to 10 1⁄2 hours for 64 mm thickness. Such delays cause increased driving resistance due to 'take-up' (i.e. the increase of shaft friction). However, there are many situations where piles cannot be driven to their full penetration without the need for lengthening or for 'drilling-and-driving' techniques. Cleaning out the soil plug is an effective way of reducing the driving resistance, thus obtaining deep penetration, because of the elimination of base resistance. It is particularly advantageous for obtaining deep penetration into coarse soils; say to develop uplift resistance, to avoid excessive settlement due to vibration effects, or to reach rock-head. This is because the base resistance in a coarse soil represents the major proportion of the total resistance to the driving of the pile. Removal of the soil plug is not particularly effective for piles penetrating deeply into clays where the base resistance is only a very small proportion of the total resistance. Drilling out the soil within the pile does not reduce the external shaft friction of the surrounding clay [9]. Refusal may be also caused not only by the soil plug within the pile but also by erratic blocks typical of the glacial regions which are like monopiles (1,376 such foundations were fully installed at the end of 2012, which represent 74% of all installed foundations), BAUER Machinen GmbH developed the trench cutter for supporting the offshore pile driving for large mono piles when pile refusal is prematurely reached. The basic method is in use since the early 1960s and is used also for oil well and soil exploration drilling to maintain boreholes in caving soils without casing [10]. The large hydrostatic pressure resulting from several hundred meters of slurry allowed retention of oil or gas in oil wells until they could capped with valving to control the fluid flow rate. The trench cutter (Figure 1) is an excavating machine that operates on the principles of reverse circulation. It is made up of a heavy steel frame with two gear boxes at the bottom of the frame. Cutting wheel drums fitted with a series of teeth are fixed to the gearboxes; they rotate in opposite directions, break up the soil and mix it with the bentonite suspension. As the cutter penetrates, soil, rock and bentonite are conveyed towards the openings of the suction box, from where they are pumped by a centrifugal pump through the slurry pipe incorporated in the cutter's frame, via the mast head into the slurry conveying system to the de-sanding plant. There solid soil and rock particles are separated from liquid bentonite which is pumped back into the trench or for storage and later reuse. The torque output of the cutter wheels in combination with the weight of the cutter is sufficient to cut into any type of soil, to crush cobbles, small boulders or weak rock. The verticality of the trench cutter and thus the trench alignment are measured on two axes by means of two independent inclinometers. Data provided by the inclinometers is processed by a computer on-board the base carrier and displayed on-line. Adjustment of verticality in the two directions is carried out by a system of steering plates. Throughout the excavation process the rig's operator is prompted by the machine's software that calculates its status and indicates the most appropriate action take.
