‘Hull Skate’ Your Way to Cleaner Hulls, Better Fuel Efficiency
and sensors, supporting the operator with data for navigation and documenting fouling on the ship hull. The specially designed motorized brush are intended to keep the hull free from fouling without causing erosion or damage to the hull coating. The vehicle is connected to the operator’s control center through an umbilical and can be operated remotely for vessels anywhere in the world with 4G coverage. Inspection and proactive cleaning of a hull will normally take around 2 to 8 hours depending on size and condition.Technology partners in the project include Kongsberg, Semcon, DNV GL, Telenor
USV Completes Greater Gabbard Survey
out seabed surveys on seven of the turbines at the 140-turbine Greater Gabbard offshore wind farm, located 23 kilometers off the UK coast.The USV is around 4.5 meters long and weighs about 750 kilograms, and can be monitored and controlled 24/7 via a satellite connection by a team at an onshore control center.Throughout the survey, the data collected was monitored from shore in real-time by experts located in the UK, to validate data collection before the vessel departed the work locations. This demonstrates the highly flexible and collaborative nature of this new technology, enabling industry experts
SHI, SKT Trial Autonomous Ship Using 5G
LiDAR, cloud-based IoT platform and T Live Caster, SK Telecom’s real-time video monitoring solution at a shipyard covered by SKT’s 5G network.The test operation took place in the sea near SHI’s Geoje Shipyard, which is covered by SK Telecom’s 5G network.From the Remote Control Center in Daejeon, located 250 kilometers from the shipyard, the companies remotely set the ship’s destination and showed off the autonomous navigation system that enabled the test ship to safely sail to the destination by recognizing and avoiding maritime obstacles. They also verified the remote

generation, where subsea infrastructure is unavailable, could provide power and communications to a Hybase on the seabed. There’s also the HyVessel concept, an autonomous surface vessel which could make the subsea system aware of situation and provide supervision capability to an onshore control center.Meggio says that the commercial solutions for recharging and underwater communications – “acoustic, optical, or whatever the market will bring” – are in now the market. “It’s just a matter of integrating them.” Then, it’s just a case of integrating
Swire Seabed Completes Unmanned Pipeline Inspection
.The inspections were completed using Kongsberg Maritime’s Hugin autonomous underwater vehicle (AUV) with the SeaKit Maxlimer unmanned surface vessel (USV) acting as the host vessel for surface positioning and communications to shore. The complete operation was controlled from an onshore control center, including launch and recovery of the AUV, command and control of the USV/AUV and monitoring of the acquisition of pipeline inspection data.The inspections were performed on four pipelines, a distance of 175 kilometers surveyed over two AUV dives. The AUV, operated by Swire Seabed, acquired bathymetri
EDS Scores 15-year O&M Contract
the 500MW Greater Gabbard in Lowestoft, Suffolk to help the wind farm fulfill its output potential.EDS will supply maintenance services on both the transmission assets and auxiliary systems, including fire systems and cranes, as well as providing CTVs. Operations will be managed from EDS’s 24/7 control center and will include network surveillance, high voltage (HV) safety management and marine coordination utilizing James Fisher’s Offshore Wind Management System (OWMS).Ryan Henderson, executive director at EDS HV Group, added, “This is a key contract award which aligns with the James Fisher

largest of its kind in the world, Vissim said. The contract is for six years and has a minimum value of 100 million NOK.Vissim's system comprises of more than 100 offshore radars, AIS and VHF sensors/base stations powered by an advanced data platform, operation is coordinated between the central control center and more than 50 distributed offshore energy assets.Today Equinor runs one of the world’s largest privately-owned sea surveillance systems. The new system will cover a distance from satellites to more than 1,000 meters below the sea surface, across the Norwegian Continental Shelf, and the
Autonomous Subsea Pipeline Inspection
A. In total, 180 kilometers of pipeline were inspected over two AUV dives.The inspections were undertaken with the subsea vehicle in autonomous mode, with a small surface vessel accompanying the AUV to provide positional updates to the vehicle and act as a communications relay between the AUV and the Control Center at Swire Seabed’s office in Bergen.The AUV, operated by Kongsberg, acquired Bathymetrical, Synthetic Aperture Sonar and visual data as part of an operation to verify the continued integrity of the subsea pipelines. According to Swire Seabed, acceptance criteria for data (quality, coverage

and technology are very complementary to our expertise. And they are in the spotlight at the moment!” said Frédéric Jallon, Technical Director at GMS.In addition, FORSSEA will soon release the NAV CAM (Navigation Camera), an innovative all-in-one ROV/AUV visual based navigation control center, with high grade calibrated optics, embedded image treatment capacity, pressure sensor and IMU. The NAV CAM has been designed to as a ROV plug-and-play system. It will be compatible with Gyros for survey applications such as subsea asset’s altitude and heading monitoring.(Image: FORSSEA
