SMD QT500 Trencher


Triumph Subsea Services is pleased to announce that it will be installing SMD’s QT500 trencher on our Windfarm Development Vessels. The SMD freeflying QT500 trencher is fitted with a patent pending cable bell-mouth for simultaneous lay and burial operations, which is ideally suited for deep water operations. The simultaneous lay and burial operations maximise lay speeds and minimise cable risk when installing into the 2m depth prelay trenches, created by the SMD patented boulder clearing prelay plough. The QT500 deploys 300kW of jetting power to cut through trench slump and sedimentation, with a jetting depressor to immediately bury and protect the cable, accurately instrumenting the burial depth.


A custom designed QT500, rated to 2000msw will be fitted on our WDVs for use in the renewable and floating windfarm sector. The WDV is multirole and adaptable, thus allowing it to readily transition into cable lay and umbilical lay operations for use within the Oil & Gas sectors if required. The key drivers and differentiators in Triumph’s sustainability growth programme and technology are based on our unrivalled innovations and industry first initiatives, such as having multirole vessels. Triumph’s use of the SMD QT500 that has ‘over the horizon’ operation capability is another example of how technologically advanced robotics and autonomous systems are utilized on our new Green Technology vessels that will be operating within the offshore wind, renewables and energy sectors.
