Acoustic Data launches high-expansion Retainer with Integrated Acoustic Telemetry

Acoustic Data has developed a new slickline deployed high expansion retainer for cement and metal alloy plug and abandonment (P&A) applications. In the case of new-generation metal alloy plugs, the HEX-Retainer can be integrated with the company’s SonicGauge Plug Verification System (PVS) for real-time long-term barrier integrity monitoring purposes.The SonicGauge PVS uses wireless communication in the form of acoustic telemetry to transmit downhole pressure measured below the barrier to surface, or alternatively, in deep-set applications, to a SonicReceiver unit that can be permanently

Hydramec's LARS for Fugro's Uncrewed Surface Vessels

Offshore surveyor Fugro has ordered a Hydramec launch and recovery system for its new uncrewed surface vessels recently ordered from Sea-Kit.Fugro, based in the Netherlands, in August ordered two 12-meter SEA-KIT X class uncrewed surface vessels (USVs), with one bound for their Asia-Pacific region and the other for North Sea operations.The first of the 12-meter SEA-KIT X class USVs is expected to be delivered to Fugro in Perth, Australia, in the fourth quarter of 2020 and will feature remotely operated vehicle (ROV) and autonomous underwater vehicle (AUV) launch-and-recovery systems and station-keeping

Four HUGIN AUVs for the Indian Navy

Kongsberg Maritime sold four HUGIN AUV systems to the Indian Defense Public Sector shipyard Garden Reach Shipbuilders & Engineers Limited (GRSE), located in Kolkata, India. This sale was  conducted in collaboration with Kongsberg Maritime India, a subsidiary of Kongsberg Maritime.The purchase, which also includes HiPAP 502 high-accuracy acoustic positioning and communication systems to support AUV operations, will be installed on the four Large Survey vessels currently in build for the Indian Navy. GRSE Chairman and Managing Director Rear Admiral (Ret’d) Vipin Saxena said: “We are

Subsea Technology and the New Routes to Residency

Efforts to increase remote capability often go hand in hand with increasing ROV residency. But exactly what form residency takes is diverging. Elaine Maslin takes a look.Dial back the clock five years and there was a movement towards an idea dubbed subsea resident remotely operated vehicles (ROVs). The idea, in simple terms, is that you increase ROV availability and reduce cost and carbon emissions by having the vehicle permanently based subsea in underwater garages. A number of vehicles could even cover a cluster of fields, potentially with different owners who can dial up, on demand, a vehicle when

Vehicle Launch: Riptide UUV-12 takes BAE Systems into Medium UUV Sector

BAE Systems unveiled the newest addition to its unmanned undersea vehicle (UUV) portfolio, the RiptideTM UUV-12, a 12-inch diameter vehicle is the company’s entry into the medium UUV market.“The Riptide UUV-12 system significantly extends the Riptide family of UUVs by taking us into the medium UUV market,” said Jeff Smith, chief scientist at BAE Systems’ FAST Labs research and development organization. “With this medium-size platform, we are strategically aligning our modular, open architecture-based UUV platform to meet rapidly expanding applications and requirements.

Inspired by Adélie penguins, EvoLogics Presents its new PingGuin AUV

EvoLogics recently introduced PingGuin, an autonomous underwater vehicle (AUV) with low-drag bionic design. The vehicle was developed as part of the MUM (Modifiable Underwater Mothership) collaborative R&D project and was first demonstrated in Kiel, Germany, in June 2020.Outstanding hydrodynamic properties of a penguin’s body became the starting point for the AUV design within the NaviMUM subproject, assigned to EvoLogics. One of the EvoLogics co-founders, Dr. Rudolph Bannasch studied Adélie penguins and the effectiveness of their locomotion since the 80s, undertaking several field

Teledyne CARIS AI Software Used in Uncrewed Offshore Survey

Teledyne CARIS, a Teledyne Technologies company, said it was an integral part of the team involved in a recent uncrewed offshore survey mission in the Atlantic Ocean. Teledyne CARIS’ Mira AI and CARIS Onboard software were present on the vessel to enable autonomous survey and real-time processing operations.The mission’s uncrewed surface vehicle (USV) built by SEA-KIT mapped over 1,000 square kilometers of the ocean floor in 22 days, while being continuously monitored via satellite communications at its Remote Operations Center in Essex, U.K. A specialized team comprised of the GEBCO-Nippon
