Pre-piling template– PIF

Piling template equipment for productive and accurate offshore piling operations

Overview

Full insight and control for highly accurate and simultaneously efficient offshore pile installation operations

In order to have full insight and control during the offshore piling operations that were part of the construction of a large OWF, Seaway Heavy Lifting contracted Seatools for the design and delivery of a piling template instrumentation and control system. Not only did the severe vibrations and shock loads that occur during piling operations pose technical challenges – the deadline too, made the project extremely challenging.

Seatools’ background in the delivery of custom-made dredging instrumentation proved highly valuable for this project. In addition to our extensive range of highly accurate and rugged subsea sensors, Seatools has extensive experience in the design of monitoring and control equipment for operations in vibration- and shock load-rich environments. All of which has contributed to the design of reliable equipment for uninterrupted piling operations. Seatools’ ability to innovate under high time pressure further enabled the development of multiple dedicated monitoring systems. These systems monitored and controlled the piling process, and allowed Seaway to stay well within the limits of the prescribed pile installation tolerances. The full scope of the project was completed within the set delivery time of five months.

Features & Specifications

  1. Facilitates high pile installation accuracies

    Enabled by Seatools’ proven subsea sensor range, the template includes various dedicated real-time monitoring systems. These highly precise systems, in combination with accurately controlled systems for pile positioning and template leveling, ensure our client stays well within the prescribed pile installation tolerances – while maintaining installation speeds.

  2. Highly reliable
    design

    Both the monitoring and control equipment as well as the hydraulic and mechanical systems for template leveling and pile positioning feature a high level of redundancy and are executed with a solid backup strategy. The architecture of the systems is based on a thorough FMEA analysis, performed in close cooperation with our client.

  3. Full insight and control over installation operations

    The integrated monitoring and control systems allow for accurate, real-time monitoring of every step of the pile installation process.
