SMD to Supply Multi-Mode Pre Lay Plough to Boskalis

June 7, 2019

Soil Machine Dynamics Ltd are pleased to announce that they have signed a contract to supply a 200Te Multi-Mode Pre Lay Plough to leading marine service provider Boskalis N.V.

Set for delivery in spring 2020, the Pre Lay Plough comes with SMD’s latest surface control equipment which will be mobilised on the bridge of a Boskalis specialist trenching vessel.

The Multi-Mode Pre Lay Plough is an established member of SMD’s power cable installation and protection product range and is available with configurations for trenching and backfill. The plough will come equipped with a 2.1m share suitable for trenching in sands and hard clays up to 600kPa and has configurations for trenching and backfill. The trenching pass creates an engineered ‘Y’ trench profile with a secure power cable pocket for subsequent lay process and the backfill pass moves the cut spoil back over the product for maximum cover.

Paul Davison, Managing Director of SMD’s Equipment Business comments, “We are delighted with this second award from Boskalis following the CBT2400 Trencher contract. We’ve worked hard with Boskalis to evolve the Multi-Mode Plough design, improve its performance and minimise environmental impact on the seabed.  Minimising lay risk and maximising lay speed are key drivers and being able to carry out a campaign of trenching and backfilling using a single vehicle makes operations economical in both cost and time. We look forward to cementing a solid working relationship.”

SMD's Multi-Mode Pre Lay Plough Completes First Job for Assodivers Ltd

June 21, 2018

World leading subsea equipment designer and manufacturer Soil Machine Dynamics Ltd (SMD) are pleased to announce that their Multi-Mode Pre Lay Plough, delivered to Greek offshore contractors Assodivers Ltd in Spring this year, has successfully completed its first offshore job in the Baltic sea.

The Multi-Mode Pre Lay Plough is the newest addition to SMD’s power cable installation and protection product range. This plough has configurations for boulder clearing, trenching and backfill. The boulder clearance pass clears a 13.0m wide route including surface and submerged boulders. The trenching pass creates an engineered ‘Y’ trench profile with a secure power cable pocket for subsequent lay process. The backfill pass moves the cut spoil excluding boulders back over the product for maximum cover. All three modes have responsive and controlled steering and a fully integrated sensor suite for as built survey of performance.

Managing Director for SMD’s Subsea Business, Paul Davison comments, “I am thrilled that we have been able to deliver the plough with all three configurations. Having multiple configurations available means this one plough can be set up to carry out a campaign of route clearance and power cable installation and cover processes making it economical in both cost and time, minimising lay risk and maximising lay speed. Assodivers are the first client who have this capability in a single vehicle. We have a longstanding relationship with Assodivers, they have two of our Atom Work Class ROV systems already in their fleet and we are pleased that they trust us and our equipment.”

The equipment was mobilised on board Assodivers’ DP-2 Construction Support Vessel, the Aethra, directly from SMD’s quayside access point.

Technical Manager from Assodivers, Aggelos Tziotakis comments, “We are excited with the opportunities that have arisen from the use of a unique tool such as the multi-mode pre-lay plough; The vehicle has already performed its maiden work in the offshore fields of the Baltic with very successful results.”

Offering a full turnkey solution, SMD delivered a 20ft Control Cabin and a 60Te stabilising frame operational in up to sea state 5 via their dedicated Deck Equipment business. The team were able to integrate the 60Te stabilising frame with Assodivers’ existing A-Frame.

The scissor type stabilising frame used in conjunction with the A-Frame is designed to maintain plough orientation and reduce side to side movement during launch and recovery; fore and aft motion is restricted by the tow wire.
