SMD deliver QTrencher 500 compact high power trenching system

March 26, 2019

Soil Machine Dynamics Ltd. are pleased to announce completion of the first QTrencher 500 compact, high power trenching system developed for submarine cable installation and maintenance specialists, SubCom.

The new QTrencher 500 system provides additional 100HP versus its QT400 predecessor, without a weight penalty for a powerful, cost effective solution. The system combines proven SMD cable maintenance tools in an ultra-compact and lightweight arrangement, to deliver ultimate power within a small footprint. The high voltage transmission provides maximum thrust and jetting performance enabling trenching capability to a depth of up to 3.0m with multiple passes dependent on the ground conditions.

Paul Davison, Managing Director of SMD’s Equipment business comments “This system is a new product developed specifically for the submarine telecoms market, and marks a welcome sign of innovation and new product development in the sector. It’s 500HP in a compact footprint and 12TE weight limit make it the best in its class. The system also benefits from jet tooling and a new suite of sensors making it digital ready for future asset management. It’s developments like this that have made SMD equipment responsible for the burial and protection of over 80% of the world’s subsea telecoms cables.”

The vehicle is equipped with SMD’s latest surface control and power cabin layout and 12.5Te Wide Angle A-Frame operational in sea state 5, an umbilical winch with steel armoured umbilical for operation in 2500mwd.

John Dahlgren, Director of submersible systems at SubCom said “SubCom’s goal was to procure a vehicle system which would exceed client expectations for reliability, performance and cable protection. The result was a trencher, which incorporates SubCom’s vast telecom cable installation experience and drive for innovation with SMD’s proven engineering and manufacturing expertise. SubCom is confident this new vehicle will lead the telecom industry in burial power and capability inside a manageable and cost effective footprint, while also incorporating the latest advancements in subsea technology. We are thrilled to be adding the system to our fleet.”

QTrencher 1600 and 48Te A-Frame Delivered to Van Oord Commences First Job

August 8, 2018

Soil Machine Dynamics Ltd (SMD) are pleased to announce that the QTrencher 1600 and its associated deck equipment package delivered in April 2018 to Van Oord, has commenced its first job at Borkum-2 wind farm.

Van Oord’s deck equipment for the QT1600, Dig-It, included a 48Te launch and recovery system (LARS) with A-Frame, cursor docking head, umbilical winch with snatch limiter and hydraulic power unit ensuring safe and reliable deployment of the QTrencher 1600 in higher sea states.

Paul Hatchett, Managing Director SMD Deck Equipment comments, “SMD have been delivering safe and reliable launch and recovery and cable handling equipment for over 35 years, and we have used our expertise to deliver a Lloyds Register approved system to our new customer, Van Oord. We have designed this LARS to offer flexibility and ease of maintenance to our customer. The compact design means that Van Oord are not restricted on the layout of their vessel, with the system being compact enough for operation across the beam and over the stern. Together with SMD’s QTrencher 1600 Van Oord will be able to increase their operational window, working in conditions up to sea state 6.”

The deck equipment comes equipped with a state-of-the-art cursor launch system which allows high sea state deployment using the lift winch. SMD’s cursor launch system protects the vehicle’s umbilical and ensures operational loads are within safety factors at all times, even when the air weight of the vehicle exceeds the safe working load of the umbilical.

Furthermore, the integration of the snatch limiting device means the system is able to handle transitions through the splash zone, from heavy-in-air to light-in-water without transferring shock loads to the umbilical. This function prevents the umbilical from becoming overloaded, and also handles slack umbilical to prevent damage during vehicle recovery which can be caused by vessel motion in high sea states.

The QT1600, Dig-It, has commenced cable installation work which should be finished in July 2018. Once completed in 2019, the Borkum-2 offshore wind farm will deliver green energy to an equivalent of 460,000 households. The offshore wind farm is located 54 kilometres off the coast of Lower Saxony, Germany.

Van Oord Places Contract with SMD for High Power Trenching Machine

May 23, 2017

April 2017: Soil Machine Dynamics Ltd (SMD) are pleased to announce the signature of a contract with Van Oord for the manufacture and delivery of a QTrencher 1600. This contract follows the successful deployment of SMD’s QTrencher 1400 on Van Oord’s Gemini Wind Farm.

Scheduled for delivery in Q1 2018, the high power trenching machine will be supplied with an SMD designed umbilical winch, along with jetting and mechanical cutting tools to tackle a wide range of seabed conditions. Additional functionality includes beach operation to offer cable installation for export and inter array campaigns.

The equipment will be loaded directly onto Van Oord’s state of the art cable-laying vessel Nexus from SMD’s Turbinia Works in Wallsend, UK. The QTrencher 1600 is scheduled to be deployed from the Nexus onto various wind farm projects in 2018.

“Van Oord have been using QTrencher 1400 on their Gemini installation campaign so already have good experience with our technology. It’s a strong endorsement of our quality and performance in the field to be able to supply direct to a contractor like Van Oord” remarked Paul Davison, Managing Director of SMD Trenching, Mining and Renewables. “With the continuing demand to lower LCOE and obligations to get it right first time, the market is demanding better performance. Our technology is well placed. We look forward to working with Van Oord, ensuring the trencher has a smooth entry into service.”

Van Oord commented,

“We have chosen SMD for a very good working experience with one of their machines and their vast track record of the subsea trenching machines”.

The QTrencher 1600 is the next generation of the QTrencher 1400 model, and the power available to the trenching tools has been optimised for offshore wind applications in shallow water. With 45 years of experience in the subsea trenching industry, SMD have developed a wide range of QTrencher vehicles from 400 to 2800 horse power. The QTrencher’s adaptability allows for application across many markets, from telecoms, through to power cables and oil & gas construction.
