Heave Compensation

Gain motion control and maximize your workability

 

Overview

Seatools provides turn-key heave compensation solutions for full-motion control over any offshore asset

Seatools has a substantial track record in the field of heave and motion compensation. We have analyzed, designed, and delivered innumerable heave and motion compensation systems: from retrofits applied to existing systems with our standardized HeaveMate® active heave compensation system, to the design and delivery of highly complex full-3D motion compensation equipment. Over the years we have developed an extensive library of algorithms for all types of heave and motion compensation systems, resulting in short project lead times.

Expertise
  • Heave compensation for cranes, winches, LARS, gangways, cargo loading systems, draw works, drag heads, and platforms
  • Active and passive heave compensation
  • Motion compensation (up to 6 degrees of freedom)
Value creation
  • Thoroughly tested and fail-safe controllers
  • Short lead and commissioning times
  • One-stop shop
Track record
  • Numerous retrofit and OEM projects
  • Full 3D subsea motion control
  • Turn-key systems: including mechanical, electric, hydraulic, and software systems

Advanced simulations, standardized control modules, and all required disciplines under one roof – our approach to cost-effective and rapid upgrading projects. Do you want to expand your workability too?

SCOPE

  • Feasibility studies, analysis, and troubleshooting
  • Custom heave and motion compensation systems
  • Upgrades and retrofits
ROV modelling and simulations

Gain valuable insights for predictable offshore operations

Our advanced simulation capabilities facilitate thorough analysis of any type of (existing) heave and motion compensation system. Extensive simulations may include vessel motions, mechanics, electronics, hydraulics, and controls. Relying on simulations, we analyze a system’s behavior, optimize parameter settings and control strategies, and test system response during mode transitions, extreme circumstances, and failure cases.

Custom heave and motion compensation systems

One-stop shop for motion control solutions suiting any of your offshore assets

Custom-made systems include passive heave compensators, active heave compensators, combined passive-active heave compensators, and 3D motion compensators. Seatools can either deliver an OEM package that includes the essentials for heave compensation (i.e. a black box controller with sensors and software), or a fully developed turn-key system that includes mechanical, electric, and hydraulic hardware and software systems. An example of the latter is the OAS heave compensation project. Our scope ranges from system simulations to offshore commissioning and testing.

Workability extension after active heave compensation upgrade

Extend the workability of your existing offshore assets thanks to our standardized solutions

Our HeaveMate® AHC standardized control system facilitates the integration and upgrading of existing systems, such as winches and cranes. We take all the case-specific conditions, requirements, and existing (drive) systems into account, and perform simulations in order to verify the correct performance of the system under any condition. Once all in-depth simulations have been completed, the pre-optimized controller is integrated in the existing system, resulting in a minimum of commissioning time. Seatools is a one-stop shop for upgrades and retrofit projects: our scope includes all required disciplines – including hydraulics and mechanical design – and we deliver our solutions ready-for-use.

HOW WE CREATE VALUE

  • One-stop shop

    Heave compensation - One stop shop

    Because we do not only have a strong control engineering department, but also house the complementary engineering disciplines such as mechanical, hydraulic, software, and electrical engineering, clients can outsource full-fledged projects to a single supplier. This benefits quality and lead times first of all, but also means that projects are performed in a far more cost-effective way and shifts the burden of additional project management away from our clients.

  • Thoroughly tested and fail-safe controllers

    Active Heave compensator testing

    Thanks to our simulations we deliver first-time-right solutions and fail-safe control system designs. Before a heave compensation system is installed on site, its control system is extensively simulated. Hence we predict the controller’s response to any condition ahead of installation, and implement the most effective control strategy. In addition, already during the design stage our simulations facilitate analysis of system component failure, such as a failing motion sensor. Like this, we create a system that features sufficient fault tolerance.

  • Short lead and commissioning times

    Here too our simulation capabilities make the difference. Simulations provide critical insights during the development stage and help us determine the most optimal control strategy as quickly as possible. Simulations also enable us to pre-program the controller’s most optimal settings ahead of commissioning. In addition, Seatools holds an extensive experience base and control algorithm library. In practice, this means our lead times are short and expensive offshore commissioning time is reduced. This has proven to create significant value for our customers, especially during complex projects such as heave compensated gangways.
