AUVS ANDROVS

Specialist manufacturer of tailor-made AUVs and ROVs

Overview

Seatools designs, manufactures, and upgrades any type of AUV and ROV

Seatools is unique in its ability to provide a full range of custom-made ROVs and AUVs. Throughout the years we have built a strong track record as a ROV manufacturer. In many cases, our innovative ROV designs have resulted in significant improvements in our customers’ operational efficiency. The Rockpiper fall-pipe ROV, with integrated inspection ROV to perform rock installation and survey in a single pass, is a case in point.

Thanks to our engineering principles, we deliver first-time-right vehicles at a minimum of required commissioning times. During the design stage, a detailed simulation model of the entire ROV – including sub-systems – is created. In order to ensure proper performance of the ROV under any condition, and to pre-tune the control system prior to commissioning so as to save valuable vessel time, this model is extensively tested in a virtual world.

Feasibility, FMEA and ROV concept engineering

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 AUVs and ROVs. The studies we conduct typically explore the feasibility of required performance criteria as set by the customer, and help ensure optimal vehicle configuration. Other typical subjects concern CAPEX / redundancy level ratio optimization, operational sequence analysis, load case analysis, operational automation analysis, and ROV dynamic positioning tolerance analysis.

ROV parts, components, sensors, and sub-systems

Field-proven AUV and ROV components and sub-systems

Seatools delivers both standardized and custom-made AUV and ROV components and sub-systems. When it comes to subsea hydraulic ROV parts and sub-systems, we deliver thrusters, compensators, filters, power packs, and valve boxes. When it comes to subsea electronic ROV parts and sub-systems, we offer a wide variety of sensors, junction boxes, terminations, and e-pods. Our component designs are based on more than 15 years of field feedback: we have successfully applied components to all our ROVs and other subsea vehicles, such as trenchers.

AUV and ROV manufacturer - bespoke solutions

Turnkey delivery of fit-for-purpose AUVs and ROVs

To be able to design and manufacture any type of AUV or ROV, Seatools combines an extensive toolbox of standardized ROV components and sub-systems, all required engineering disciplines, and broad experience regarding ROV technology. Our track record contains various examples of innovative ROV solutions that enables our customers to perform their operations in a highly efficient way. The Rockpiper FPROV with integrated survey ROV is a case in point. The Rockpiper enabled Boskalis to achieve significant operational cost savings as it facilitates direct post-process surveys.

ROV maintenance, repair, and upgrades

Extended performance thanks to ROV maintenance, repair, and upgrades

Seatools performs ROV maintenance, repair, and upgrade activities on self-manufactured as well as on third-party AUVs and ROVs. We executed multiple upgrading projects on fall pipe ROVs, for example. Our work enables our clients to perform tasks that stretch far beyond the original purpose of their ROVs.

One stop shop ROV supplier includes delivery of ROV simulators

Gain proficiency faster and experience abnormal situations in a controlled environment

Seatools is experienced in the development and delivery of real-time ROV simulators used for effective operator training. Real-time ROV simulators avoid expensive and risky training at sea, and allow for exact planning of operations. Our on-board simulators make good use of employees’ time: they enable practice and preparation for jobs during transit.

HOW WE CREATE VALUE

  • Efficient operations thanks to excellence in vehicle dynamic positioning and automation

    Efficient operations through ROV dynamic positioning excellence

    In order to minimize rock spillage, our clients in the field of subsea rock installation demand for the highest possible ROV positioning and navigation accuracy. As a result, throughout the years we have developed ROV control systems and related simulation models which allow for outstanding ROV positioning and navigation accuracies. This results in highly accurate and automated ROV operations, thus saving valuable vessel time and relieving operator from exacting labor.

  • Effective operations thanks to fit-for-purpose vehicles

    Bespoke AUV and ROV systems for commercial, scientific and military purposes

    Our strongly innovative capacity enables us to design and deliver tailor-made ROVs and AUVs for any commercial, scientific, or military purpose or requirement. Fit-for-purpose configurations can vary in performance specifications, including in depth rating, payload, tidal conditions, and auxiliary power requirements. The ROHP is a case in point of a highly customized ROV: the many tasks that our client required can be performed by a single ROV, which results in highly effective operations.

  • ROV designs based on standardization

    ROV designs based on standardization

    Not only are we able to deliver tailor-made AUVs and ROVs, 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.
