Subseatrenching

Effective subsea cable and pipeline (de-)burial by means of bespoke subsea trenching solutions

Overview

Seatools designs, manufactures, and upgrades any type of subsea trencher

Seatools is unique in its ability to provide a wide range of customized subsea trenching equipment. In combination with our subsea excavation knowledge, our subsea equipment engineering capabilities allow us to develop any type of subsea trenching vehicle. We develop and deliver:

• Mechanical trenchers
• Jet trenchers
• Pipeline ploughs
• Cable ploughs

In addition to complete subsea trenching vehicles, we also offer trenching (performance) upgrades, modifications, and maintenance services. As shown by the lead times of various past projects in this field, Seatools designs, manufactures, and modifies trenchers in a very short period of time thanks to its flexible approach.

Expertise
  • Jet trenching, mechanical trenching, subsea ploughing
  • (de-)burial of subsea cables and pipelines in pre- and post-lay conditions
  • Control systems for trenching automation (including haptics)
Value creation
  • Innovative, fit-for-purpose trencher designs
  • Flexible and short lead times
  • Trencher designs based on standardization
Track record
  • Delivered multiple innovative cable and pipeline trenchers
  • Performed multiple trencher upgrading projects
  • Delivered custom subsea trencher in 7 months: from scratch to FAT

SCOPE

  • Feasibility, FEED studies, and concept studies
  • Bespoke trenching equipment
  • Maintenance, repair, and upgrades
Subsea trenching conceptual design

You provide the case and requirements, we seek out a solution

Seatools is capable of and experienced in the performance of early-stage studies for the development of fit-for-purpose subsea trenchers. The studies we conduct ensure that the most optimal seabed trenching solution is developed given a particular set of customer (performance) criteria. Typical subjects and criteria include required (economically feasible) progress velocity, deployment methods, required trench profiles, soil conditions, terrain conditions, wear behavior, cable or pipeline properties, operating conditions, and CAPEX/OPEX behavior of potential solutions.

Bespoke subsea trenching equipment

Innovative trenching equipment, fit for your purpose

Seatools developed a distinguished track record regarding the development and delivery of innovative, custom-made subsea trenchers. Our knowledge of subsea equipment design, dredging technology, and control engineering, in combination with our creativity, leads to the development of highly effective, custom-made seabed trenchers. Upon delivery, our equipment is ready for use, and includes operator training programs.

Subsea jet trencher upgrade

Extend the performance and applicability of your existing subsea trenching equipment

Seatools performs maintenance, repair, and upgrade activities on self-manufactured as well as on third-party subsea trenching equipment. Seatools performed multiple upgrading projects that enabled clients to perform trenching projects with equipment originally designed for significantly different purposes. The Oceanjet 900 is a case in point. Here we successfully transformed a free-flying ROV trencher into a tracked vehicle that achieved a significant increase of trenching speed.

HOW WE CREATE VALUE

  • Flexible and short lead times

    Arthropod subsea trencher - 7 months lead time

    Generally speaking, downtime and long lead times are unacceptable in our capital-intensive industry. Because we understand this, our organization is set up in such a way that projects can be executed within a short time frame. The total lead time for the custom-made Arthropod trencher, for example, was only seven months: from scratch to FAT.

  • Innovative, fit-for-purpose trencher designs

    Fit for purpose subsea trencher designs

    By taking into consideration our clients’ (performance) criteria, we deliver effective trenching solutions that significantly improve the overall economies of our customers’ operations. Our strongly innovative capacity enables us to deliver subsea trenching equipment for any purpose or criterion: from soft-soil to hard-rock capability, and from self-propelling ROV trenchers to towed sleds. The highly innovative Arthropod trencher and the Jetting Bull trencher are cases in point.

  • Trencher DESIGNS BASED ON STANDARDIZATION

    Trencher designs based on standardization

    Not only are we able to deliver tailor-made subsea trenchers, we also make sure to deliver vehicles in an effective way. This is thanks to our extensive technology toolbox that contains standardized modules and components. The benefits of our approach are manifold: short lead times, competitive pricing, and reliable and proven technology thanks to predictable performance.
