controls and user interface under different degrees of operational difficulty. DeepWorks enables trainers to measure
performance by monitoring the time taken to complete a task, smoothness of control and deviations from planned routes, and forces on and pay-out of the tether, all under various sea conditions. DeepWorks also allows trainers to temporarily ‘break’ circuits or components to test how well pilots detect and respond to failures. It is important that pilots are able to make the right call when determining if a mission can still be completed safely when ROV systems are compromised or a worsening sea state is encountered.
Fly-throughs A common requirement is to turn clients’ subsea field and site engineering drawings into 3D models for fly-through demonstrations in the simulator. To automate the process, DeepWorks offers a plug-in to Autodesk 3ds Max that allows third party graphics models to be loaded into the simulator’s graphics library. Te scenario then picks up the new graphic for flying the mission. Fly-throughs have impact early in projects when concepts need to be conveyed effectively and stakeholder buy-in is being sought. Tey are also a valuable means of communicating with offshore teams, enabling them to become familiar with new equipment and tasks, refine new procedures and improve levels of understanding for more efficient and safe operations.
components from pre-defined libraries, engineers can rapidly prototype subsea solutions containing vessels, cables, and winches, as well as a wide selection of static, dynamic and velocity controlled bodies. Engineers can also add their own custom components by importing 3D engineering models and defining key properties. Adding Fugro’s real-time monitoring library
to DeepWorks Engineer, enables live situational monitoring of topside and subsea activities. DeepWorks Engineer Live accepts input via ship systems including Fugro Starfix Message Manager, and processes NMEA standard inputs such as GPS from the vessel, Gyro and USBL data from the ROV or transponders fixed to cables. Vessel, ROV and cable positions are then updated and displayed in real-time. Often turbidity or poor sight lines means cameras are ineffectual. Offering management and operations teams a clear window of the entire field with their own choice of viewpoints enables them to see what they want and make better decisions as real operations unfold. As a service, Fugro also uses DeepWorks to speed

For concept selection and design feasibility, DeepWorks also offers an engineering variant that runs on the desktop. By dragging and dropping
up deployment evaluation of new ROV deployed tooling solutions. As commercial pressures squeeze design time, the sooner simulation is involved the faster and cheaper it becomes to change ROV and tool designs prior to manufacture. Tis reduces reliance on expensive and time consuming prototypes and wet trials. Full hydraulic and electrical circuit modelling combined with a suite of actuators and manipulators, means virtually any ROV or tool can be created and tested in realistic scenarios. Monitoring the structural integrity of offshore platforms is time consuming and expensive. Fugro regularly assists customers in the design and development of ROV deployable tools for non-destructive testing of the condition of subsea structures. TWI in Cambridge developed a prototype Long Range Ultrasonic Tool (LRUT) designed to be deployed by ROV and clamp around vertical or horizontal jacket tubular members. Robotic Technologies created a simulation of the tool deployment by ROV and simulated the tool being aligned and attached to the members. DeepWorks was used to model the actuator mechanisms which controlled the tilt angle and rotation of the tool as well as the operation of the jaw which closes around tubular members. DeepWorks’ ease of use allowed TWI’s LRUT models to be rapidly imported and configured and early simulations were possible within a day. ●
