Configurations

A ROPOS for every ship

The ROPOS vehicle has three general configurations to best suit the operational goals and budget of our users. Each configuration is designed to allow for flexible deployment scenarios on a variety of vessel of opportunity. Since its first dive, the ROPOS system has been shipped throughout the world and mobilized on over 16 different vessels.


Control Lab

Working together is key

By normally integrating within a ship's lab instead of a dedicated operation's container, the ROPOS control lab brings everybody involved in the dive together. Scientists, students, engineers, and ROPOS operators can all easily communicate face to face in an atmosphere of collaboration that enhances the quality and efficiency of all dive operations; from brainstorming on complex procedures to coordinating the perfect picture.

Manipulators

Handling the most complex tasks

When it comes to getting things done, from delicate sampling operations and difficult sub-sea connections to managing 300 lb instruments, ROPOS is equipped to handle it. Its two powerful and agile Kraft Predator 7-function force-feedback manipulators offer unparalleled controllability and responsiveness that allows our skilled operators to efficiently perform complex tasks in unstructured and challenging environments.

Imaging

Like the ocean, simply stunning

Equipped with state of the art HD cameras, a high-sensitivity full-frame 12.1 megapixel digital still camera and over 3700 watts of far-reaching lighting, ROPOS captures the stunning beauty of sub-sea environments in a wide-field of view that makes you feel as if you were there. Once at the surface, all video and images are geo-referenced and recorded in a digital format that can easily be used for anything from creating beautiful cruise highlights to detailed image analysis.

Tools and Sampling

A tool belt you can count on

ROPOS and its operators have built their reputation on the successful development, implementation and use of complex scientific and engineering tools for a wide range of seafloor tasks. From the brute strength of rock-cutting submarine chainsaws or jetting pumps to the most complex and delicate scientific apparatus, ROPOS has “done it all” and is always ready for a challenge. Find out how our custom sampling tools, such as the bio-box or suction sampler, can help you by visiting the Tools and Sampling section.


Data management

A powerful tool to manage your data

A ROPOS expedition can involve 20 to 30 scientists, most of whom collect data, imagery, samples, and observations using an array of instruments and sampling devices. Efficiently managing and safely archiving massive amounts of data at sea is a challenge we take seriously.

Our Integrated Real-time Logging System (IRLS 2.0) is a powerful and intuitive annotation tool that brings together framegrabs, digital still pictures, and many other files with flexible organizational elements that create a dataset that is tailored to your needs; it helps you make the most of your time offshore and facilitates review and post-expedition analysis.

Navigation

Accuracy and repeatability

The ROPOS system is equipped with state of the art navigation sensors that are merged to deliver a best solution using our LOKI Kalman filter. With this geodetically accurate and repeatable sub sea positioning, ROPOS can safely and quickly complete challenging surveys and dives.

All of these sensors, systems and data are managed, shared and controlled using the SEA's Seascape and Workboat software suite. With these powerful tools, our navigators can handle any operational requirements, give you virtually any output, as well as insure that you, the bridge and the ROV pilots always have a real-time picture of the operations.


Telepresence

Collaborate with distant shores

With satellite technology, the number of dive participants is no longer limited by the size of the support vessel or researchers being able to go to sea for several weeks at a time. Shore-based researchers can now participate in the offshore work without leaving their laboratories. Particularly valuable when researchers are only involved with short duration sampling or surveying or when a quick expert opinion is required our satellite system provides live video and 2-way communication to laboratories ashore.

Support

Things happen, we come prepared

In an extreme environment that often pushes equipment to its limits, we come prepared. From preventive maintenance to the most daunting of repairs, the ROPOS system sails with a full complement of spares, specialized tools, and documentation. Along with knowledgeable and experienced operators, this ensures that when something happens we can get back to diving with no or minimal impact on the valuable time you have offshore. If deck space is scarce, everything is modular and can be moved in ship's labs and workshops.
