PiPeliNe ANd POwer CABle iNSTAllATiON rOV The QTrencher (QT) 1400 and 2800 remotely operated vehicles (ROVs) are based on two high strength steel chassis designs which provide high power trenching capability for the burial of cables, umbilicals and large diameter pipes up to 3m deep in various water depths. The ROVs use variable high flow or high pressure jetting to optimise the trenching to suit the anticipated conditions. The QT1400 can be fitted with tracks and/or a rear eductor to enhance burial of large diameter products, it can also be supplied with independent track bases for chain cutting trenching, core drilling or cutter dredge applications. The QT2800 is the world’s most powerful free-swimming jet trencher. With more than 2 megawatts of total power, the trencher delivers 1.5 megawatts of jetting power. SMD offer a turnkey, integrated solution including SMD designed high sea state launch and recovery systems (LARS) and umbilical systems. feATUreS • Optional rear eductor for large product burial • Optional track modules for hard ground trenching • Variable high flow or high pressure jetting for optimised trenching

MULTI TASK BASE MODULES The QTrencher (QT) 1400 system utilises a core buoyancy module with integral HPUs, thruster pack, water pumps, cameras, central control pod, etc. This can be attached quickly and easily to various functional base modules which include, but are not restricted to, jet trenching module, chain trenching module, core drilling module and crane dredge cutter module. The base modules are connected to the core buoyancy module with mechanical linkage pins, wet connectors, water hosing and hydraulic piping where necessary for minimal change-over time. SMD offer a turnkey,...
