TOWED SYSTEMS SMD's towed systems are designed to bury subsea telecommunication and power cables 1500mm diameter. Available systems include the Multi-Depth Plough (MD3) Heavy Duty Plough (HD3), Ultra Duty Plough (UD3) and Multipass Plough (MP) systems, supplied with tow load capability of 80, 120, 150, 250 have powered steering and variable depth control to maximise cable protection. All Smart Ploughs have optional jetting to transform progress rates in dense sands. SUBMARINE CABLES PLOUGH RANGE POWER & UMBILICAL CABLES wide range of problems which require a subsea remotely operated...

The Q-Trencher (QT) 400, 600, 800 and 1000 remotely operated vehicles (ROVs) are based on two aluminium chassis designs which provide high power trenching capability for the burial of cables, umbilicals and small 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. Vehicles can be fitted with tracks and/ora rear eductor to enhance burial of large diameter products, as well as a suite of tools for maintenance operations. With their high thrust, the vehicles are capable of...

QTUOO BASE MODULES MULTI TASK BASE MODULES The Q Trencher (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, 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...

Q-TUOO BASE MODULES • Track based free fly crane mounted cutting head or jet cutter with integral dredging for site clearance operations. • Dredge pump capable of transporting CORE DRILLING • Track based wire line core drilling module for soil investigations with 75mm drill rods and up to 10te push force, together with drill • Supplied with subsea loaded drill magazines for drilling depth beyond 90m.

FLEXIBLE SLOT PLOUGHS The Smart Plough range including the Multi-Depth Plough (MD3), Heavy Duty Plough (HD3] and Ultra Duty Plough (UD3), is recognised globally as setting the standard in cable ploughing, reliably trenching in most soils including sands, clays and soft rock. The range is designed to handle cables up to 150, 200, 300 and 400mm diameter electrical cables and repeaters for telecommunication systems. The ploughs come with a further range of cable MBR capability Using patented technology, the ploughs are designed to minimise pull force requirements and provide effective...

The Multipass Plough (MP) builds on SMD's reputation forthe continuous development of products. The MP sets the standard globally for multipass pipeline ploughing offering remotely variable multipass capability. This allows the operator to remotely adjust the depth during trenching. The plough system also includes SMD advancements such as Hi-Tow points and the active share track, making the MP the most advanced pipe trenching technology in the world. Towing capability ranging 250te, 300te and 350te vessel pull, combined with the track drive and jetting ensures maximum burial capability. The...
