Introduction       We provide flood defence and harbour site investigations, using cone penetration testing, sampling and the installation of geotechnical instrumentation.     Our cantilever frame (image above, details below) enables testing close to wharf and quay walls, while the overwater rams can be deployed from jack-up barges and pontoons.     We have a variety of self propelling wheeled or tracked units for less restricted testing, and where embankment loadings are critical, perhaps due to embankment stability problems, then Lankelma has a selection of lightweight, low ground bearing tracked units. CPT rigs >>       Click here to dowload our capability statement 3.20MB     Overwater rams     This CPT unit is primarily a stand-alone 20 tonne hydraulic ram set that has been modified to enable installation onto a pontoon or self-elevating jack-up platform that provides a safe and stable environment for both in-situ cone penetration testing and drilling.   The overwater rams are self-contained, and are supplied with a dedicated hydraulic power pack, operator and weatherproof data acquisition system. The system can work in conjunction with either a conventional cable tool boring rig or rotary drill. When deployed from a jack-up platform these rams are ideally suited to a wide range of coastal nearshore projects including bridges, long sea outfalls, pipelines, developments for ports, harbours, jetties and marinas. see an example project >>       Cantilever frame     The cantilever frame CPT unit is a cost-effective alternative solution to deploying a self elevating jack-up in certain environments, such as in close proximity to harbour quay and jetty walls.     This system can be used as a stand-alone item of equipment or alternatively can be mounted on a variety of land based or marine equipment. see an example project >>      UK14 - excavator mounted CPT unit     As part of  our railway research and development, Lankelma has developed a CPT unit that can be attached to a mechanical excavator boom arm.     UK14 attaches to any “Miller Quick Hitch” compatible mechanical excavator that can lift the 2.2 tonne weight of the rig to the desired height of the embankment, or test location. The unit is self contained with its own bespoke power pack and generator set, and is ideally suited to difficult access locations.     The available reach of the unit is limited by the reach and lifting capacity of the mechanical excavator, but  6 - 10m is not uncommon. As larger excavators are becoming available, so too is the reach capability of the CPT unit.    see an example project >>        UK7 - the 'Bogskipper'     A compact 8.5 tonne lightweight, low ground bearing pressure track mounted unit, that is ideally suited to working on restricted width embankment crests. The unit has a maximum speed of 35mph and is fitted with rubber tracks. These features enable the unit to move economically between test locations and with minimal ground disturbance. This tracked unit has also been deployed onto, and operated on a variety of self-elevating jack-up barges. see an example project >>      Specialist plant - ROV - (remotely operated vehicles)     The successful completion of ground investigations within the marine environment, especially in the near shore environment, is difficult, both in terms of the quality of data that must be obtained and the management of the environment (waves, current, water depth and wind). Often in exposed marine settings, downtime of geotechnical and ancillary equipment can be  due to adverse weather conditions.     For appropriate projects, compact track-driven ROV systems have an enhanced versatility in that they can be used as the CPT deployment platform and hence overcome many of the external factors causing downtimes.     The ROV systems are available as 4 - 40 tonne units that can be used to mount both light and heavyweight seabed CPT units, and can be deployed from a variety of support platforms such as landing craft, multicat or barge vessels as well as self-elevating jack-ups.  see an example project >>       Conventional CPT units   When weight or site access constraints do not exist, Lankelma operates a large fleet of 20 tonne thrust capacity all terrain trucks, tracked vehicles as well as combination track-truck mounted units. see more >>
