Bluefin and NRL Complete Long-Endurance UUV Mission from Boston to New York

Bluefin Robotics, a leading provider of Unmanned Underwater Vehicles (UUVs), announced that the company, in support of the Naval Research Laboratory (NRL), has successfully completed a long-endurance UUV mission from Boston to New York totaling over 100 hours with NRL’s Reliant “Heavyweight” UUV. The multi-day mission exercised UUV autonomy methods and demonstrated the capability of a high capacity energy configuration.

Further, the endurance test was designed to push the boundaries of traditional UUVs with the objective to uncover the challenges and requirements for significantly extending UUV endurance for new applications. The exercise is part of a series to support NRL’s research in UUV-based technology for the US Navy.

Reliant, is an advanced version of the Bluefin-21 vehicle and, when equipped with a Low Frequency Broadband (LFBB) sonar payload, is the prototype SMCM UUV Knifefish system for the US Navy. The vehicle navigates using a fiber-optic gyro-based INS along with supplemental data from a GPS and a Doppler Velocity Log (DVL) to enable precise navigation underwater for long endurance missions. Reliant utilizes Bluefin’s modular vehicle design that enabled the team to easily remove the payload section and add additional energy sections increasing the system’s energy capacity to nearly 40 kWh of power. Configuration took place over only a few days at Bluefin’s headquarters in Quincy, Massachusetts.

The team mobilized the vehicle on the Boston Harbor Cruise’s, M/V Matthew J. Hughes, and deployed it outside Boston Harbor. To optimize for endurance and range, the vehicle traveled at an average speed of 2.5 knots at 10 meters water depth, resurfacing every 20 kilometers for navigation updates over GPS. Team members on M/V Matthew J. Hughes and onshore were able to receive vehicle status information over Iridium satellite system. While the support vessel was available, it did not provide navigational updates to the UUV, leaving the system to travel completely autonomously. After 109 hours of operation and transiting over 500 kilometers through strong currents, the system successfully reached its end point in New York Harbor with 10% of its battery life remaining.

The overall effort was funded by the Office of Naval Research.

UTC 2017

The subsea industry has, as all other parts of the oil & gas industry, been seriously rattled by the most severe downturn in the hydrocarbon energy era. However, the realization of what hit us and actions to be taken to sustain a healthy and profitable future is still on-going – unfortunately with thousands of colleagues paying the price by losing their job as one of the most severe consequences. At this time, there are signs that we have reached bottom in terms of most industry indicators, but few experts expect a sharp recovery. Many seem to believe that a slow recovery is what the industry needs in order to avoid an unsustainable capacity build-up, as seen in the period after the financial crisis. Considering the uncertainty of what the future will bring, this year’s UTC Program Committee have decided to challenge all of us to present ideas, experiences, technological innovations, business models and execution models for how to shape our subsea future and explain how and why subsea is the future.
UTC welcomes abstracts based on the topics listed below. If selected, please consider writing a paper in addition to the UTC presentation. From 2017, UTC papers will be published in an international database.
