ADVANCED SIMULATIONS AND CONTROL ENGINEERING

Predictable performance of equipment and operations thanks to advanced simulations and controls

Overview

FROM MODELLING AND SIMULATIONS OF MISSION-CRITICAL OFFSHORE AND SUBSEA EQUIPMENT TO REAL-TIME MISSION SIMULATORS

As a specialized manufacturer of mission-critical equipment for the capital-intensive offshore industry, Seatools understands that equipment reliability and first-time-right performance are key criteria for our customers. In order to fulfill our clients’ stringent requirements, over time Seatools developed distinguished in-house simulation and control engineering competences, allowing for extensive virtual testing of (innovative) offshore and subsea equipment. Thanks to our advanced simulations, we deliver high-end equipment that undergoes extensive virtual testing for a variety of conditions ahead of commissioning. As a result, only minimum fine-tuning is required upon delivery, commissioning times are kept at a minimum – saving valuable vessel time – and the performance of our equipment is extremely predictable.

Expertise
  • Simulations of mission equipment such as cranes, ROVs, gangways, heave compensators, drive systems (electric and hydraulic), and tensioners
  • MIL, SIL, and HIL simulations (combined with FMEA)
  • Control engineering and systems (including haptics)
  • Training simulators
Value creation
  • Combination of simulations and extensive practical experience
  • Combination of simulations and in-house engineering disciplines

Track record
  • Modelled, simulated, and developed numerous ROV control systems
  • Performed numerous advanced simulations, such as equipment-seabed interaction and hoisting cable modelling
  • ROV training simulators

During FMEA we identify the potentially weak points of a design, while simulations allow us to analyze consequences and failure-handling strategies. This approach results in maximum equipment reliability. Learn more?

ROV modelling and simulations

Physical, mathematical, and logical modelling of complex systems

At Seatools, we have considerable experience in modelling offshore and subsea equipment of virtually any type, including cranes, ROVs, gangways, heave compensators, drive systems (electric and hydraulic), and tensioners. Modelling is often followed by simulations. In case of ROV modelling, for example, influences such as hydrostatic, hydrodynamic, currents, umbilical drag, ROV reaction forces, thruster-thruster interaction, power supplies, sensor performance, and operator commands can be modelled.

Offshore and subsea (HIL) simulations

GAIN CRITICAL INSIGHTS ABOUT EQUIPMENT PERFORMANCE THANKS TO ADVANCED SIMULATIONS

Seatools is able to perform various types of simulations, which include MIL, SIL, and HIL (Hardware In the Loop) simulations. Simulation test programs can include functional testing, failure mode testing, and performance testing. Failure mode testing, for example, simulates signal, sensor, actuator, and equipment failures. In case of performance testing, the control system’s performance is tested under different operational and environmental conditions.

ROV control system for full positional control

PRE-PROGRAMMED AND OPTIMIZED CONTROLLERS FOR EFFECTIVE OPERATIONS

Based on modelling and simulations, Seatools is capable of selecting the appropriate control strategies and can define the required sensor specifications for proper performance of mission equipment under any condition. Seatools is particularly experienced in ROV control systems and advanced hydraulic control systems. Because we combine control system development with advanced simulations, we deliver the controller with pre-programmed, close-to-optimal controller settings. An offer that has proven to generate great value, as it significantly reduces expensive on-site commissioning times while resulting in highly accurate control systems.

HMI of ROV control system

RELIABLE, TIMELY, AND ACCURATE OPERATIONAL DATA, UNDERSTOOD AT A GLANCE

Not only does the quality of a control system depend on a solid controller (strategy); in order to achieve tightly controlled operations at remote locations, the quality of a Human Machine Interface (HMI) is equally important. Seatools accumulated an extensive track record regarding HMI designs for a wide variety of (remote) vehicles and equipment. Our expertise includes haptics, which can provide the operator with force feedback on top of visual feedback. The feature can be extremely useful when operating heavy-duty equipment in remote locations.

Offshore training simulators

GAIN PROFICIENCY FASTER AND EXPERIENCE ABNORMAL SITUATIONS IN A CONTROLLED ENVIRONMENT

Seatools is experienced in the development and delivery of real-time mission simulators, by means of which it facilitates effective operator training. By extending a SIL or HIL simulation model with an operator MMI or 3D visualization training simulator, for example. Doing so avoids expensive and risky training at sea, and allows for exact planning of offshore operations.

HOW WE CREATE VALUE

  • COMBINING SIMULATIONS WITH RELATED IN-HOUSE ENGINEERING DISCIPLINES

    Enhance quality of offshore and subsea simulations through multidi ciplinary approach

    Our simulation experts closely cooperate with other internal engineering disciplines in an iterative way. Related disciplines that provide relevant knowledge and insights include mechanical engineering, electrical engineering, software engineering, and hydraulic engineering. This creates an internal feedback loop, which strongly influences the quality of our simulations and the concepts under study.

  • ONE-STOP SHOP: SEATOOLS REALIZES SIMULATED SYSTEMS

    Realization after ROV simulations

    More than our ability to realize the simulated system, our lead times are short thanks to our simulation capabilities. Effective in-house knowledge transfer between disciplines on the one hand, and simulations that shorten practical testing and commissioning times on the other hand, result in custom-made equipment delivered within very short time frames.

  • COMBINING SIMULATIONS WITH PRACTICAL EXPERIENCE

    HQ ROV control system through integration of practical experience

    Many of the systems we realized we also simulated. This means we house a large knowledge base when it comes to the practical performance of components, such as sensors and hydraulic components. Thanks to our hands-on knowledge base, which has proven to be of great value, we know which factors are of critical importance when performing advanced simulations.

Enhance quality of offshore and subsea simulations through multidi ciplinary approach

Thanks to simulations, our ROV control systems are so accurate they allow us to dynamically position a 25-ton fall pipe ROV within 10 centimeters, resulting in minimum rock spillage. Do you require accurate operations as well?
