DNV to Publish New Offshore Rules and Standards in July
Classification society DNV said it is set to publish its new set of rules and standards for the offshore industry.The new rules, which cover several segments, including underwater systems and installations, offshore units, diving systems, structural design, and drilling systems, will be published in July and enter into force on January 1, 2025. They have been developed with extensive industry feedback, undergoing an external hearing process before their publication and entry into force.“The offshore sector is one of the most innovative in the world,” said Torgeir Sterri, Director of
Furuno's Berthing Aid System Receives ClassNK's Endorsement
Japanese classification society ClassNK has granted its Innovation Endorsement for Products & Solutions to a Berthing Aid System developed by Furuno.Furuno's Berthing Aid System displays the distance and angle between the ship and the quay to assist in berthing operations.The Berthing Aid System uses LiDAR to calculate the relative distance and angle between the quay and hull, and displays superimposed images for situational awareness. The system aims to improve safety during berthing by measuring and visualizing the positional relation between the quay and ship, which was previously measured
ABB to Supply Ice-Classed Azipod Propulsion for Research Vessel
speed of two knots. The ship is designed to operate both bow first and astern in ice with an enhanced Polar Class 4 (PC4) ice-breaking level. With a capacity of cruising range of 15,000 nautical miles, it can accommodate a crew of 80 people.The new research vessel will be equipped to China Classification Society (CCS) LEVEL 2 notation standards on digitalization and fulfill Underwater Rated Noise SILENT A notation. SILENT A notation covers vessels that are acoustically sensitive, whose underwater noise emissions are controlled to benefit data capture and minimize ecological impact. The criteria are
Ørsted Unveils USV for Met-ocean Measurement
initiated a serial production based on its successful prototype named Hugin USV. The prototype has been operating in Danish and Norwegian waters and has reportedly experienced waves up to nine meters in the North Sea. Hugin USV also achieved type validation as a floating LiDAR system by Norwegian classification society DNV, allowing it to be used for commercial operations related to wind farm development.As was the case for the prototype, the new USVs will be constructed by Danish shipbuilder Tuco Marine Group, and the USV control system is delivered by the innovative Norwegian company Maritime Robotics
As the Clock Ticks on the Titan Sub, an Expert Explains What Safety Features a Submersible Should Have
, the engineering and regulation of deep-sea submersibles remains somewhat uncharted territory. And since the Titan operates in international waters, it is technically free from governance by any single nation’s regulations.In this case, most submersible designers would elect to have a classification society certify the vessel’s design. OceanGate made the conscious decision to refuse to do this for the Titan.Seaworthiness of submersiblesWhen we talk about the “seaworthiness” of a marine vessel, we are essentially asking if it is fit for purpose, safe to operate, and compliant
ABS Grants AIP for Saildrone Uncrewed Surface Vehicles
Classification society the American Bureau of Shipping (ABS) has issued approval in principle (AIP) certificates to Saildrone, including the first AIP for a 10-meter commercial uncrewed surface vehicle (USV), the Saildrone Voyager. Approvals were issued to Saildrone for both the Voyager and Surveyor ocean data collection platforms. The AIP is an important step to class for Saildrone’s vehicles.Alameda, Calif. based Saildrone provides ocean data using uncrewed vehicles, with nearly 25,000 days at sea and nearly 1,000,000 miles sailed. Primarily powered by wind and solar energy, Saildrone’s
IMO Targets Subsea Ship Noise with New Draft Guidelines
in establishing mechanisms and programs through which noise reduction efforts can be realized.The draft guidelines revise the previous guidelines (issued in 2014). They include updated technical knowledge, including reference to international measurement standards, recommendations and classification society rules. They also provide sample templates to assist shipowners with the development of an underwater radiated noise management plan.The draft guidelines will now be submitted to the Marine Environment Protection Committee (MEPC 80), which meets from 3-7 July 2023, for approval.The draft guidelines
New System Reduces Underwater Radiated Noise from Ship Propellers
said.According to the company, results were further verified in tests on the sub-cavitating propellers on Princess Royal, a 19m research catamaran operated by Newcastle University. And last year, CFD Finite Element (FE) propeller stress tests were successfully completed in accordance with classification society DNV rules.Cavitation sweet spot"We have found the optimum number of holes required to reduce the noise. So long as the right number of holes are placed in the most effective positions, a cavitation sweet spot can be achieved,” said Eikeland.“It’s not a case of simply
Exail's DriX USV Gets Lloyd's Register Certification
Marine classification society Lloyd's Register has awarded its first certification for an Uncrewed Surface Vessel (USV) to the DriX maritime drone.Developed by Exail, a high-tech company and pioneer in the field of maritime autonomy, the DriX USV is operated by major hydrographic institutes and energy companies worldwide and has already received Bureau Veritas Approval in Principle (AiP).The new certification attests that the surface drone meets critical safety requirements to be operated at sea. The DriX system design was reviewed against the Lloyd’s Register Code for Unmanned Marine
