Expedition to Capture First 4K Images of the Titanic

A manned submersible set to survey the RMS Titanic wreck site this summer will be equipped with a range of high-tech underwater imaging equipment that will capture the first ever 4K images of the historic shipwreck. Starting in June 2018, manned submersible services provider OceanGate Inc. will lead a group of scientists, content experts and mission specialists to explore and survey the wreck site in a series of week-long missions from St. John’s, Newfoundland. For the mission, OceanGate's manned submersible Cyclops 2 will be equipped with cameras and lights from Canadian firm SubC Imaging

The Quest to Find and Explore USS Indianapolis

. In the early hours of July 30, 1945, having just completed a secret mission to deliver materials from California for the first operational atomic bomb, “Little Boy” to a naval base on the Pacific island Tinian, Indianapolis was en route from Guam to Leyte when it was torpedoed by Japanese submarine I-58.   Indianapolis sank quickly – reportedly in just 12 minutes – leaving little time for the crew to deploy lifeboats or for an emergency signal to be sent. It is estimated that 800 of the nearly 1,200 Sailors and Marines on board survived the sinking, but a communication error

According to Sidus Solutions, the camera maintains full 4K resolution while providing excellent focus with a 20x zoom and a combined optical and digital zoom of 144x. The SS490 delivers better picture quality than non-4K models due to its use of HDR (high dynamic range). This is especially helpful with varying lighting conditions such as working with multiple ROVs or reflectivity from stainless steel objects. “We developed

Kongsberg Introduces cNODE Micro

Kongsberg will unveil the innovative cNODE Micro system at Ocean Business this week. As the smallest member of the highly regarded cNODE series of subsea transponders, the new cNODE micro is designed to provide range accuracy better than 2 cm and is ideally suited for divers and shallow water ROVs, at depths down to 600 meters. With dimensions of 245 x 55 mm, cNODE Micro is both compact and light weight. It uses Kongsberg Maritime’s proprietary Cymbal digital acoustic protocols to provide the optimal positioning performance using the Kongsberg range of SSBL systems, from μPAP through

Next-Generation Subsea Metrology: Better Measurements, Fast

the 3D laser data with precise underwater acoustic and inertial navigation information, it is now possible to generate centimeter resolution engineering models from which accurate measurements can be instantaneously and repeatably captured.   Shared Knowledge & Communication In conventional marine construction support terminology, metrology is the work done by surveyors and ROV to acquire various subsea measurements, typically between flanges on separate pieces of subsea infrastructure. These measurements allow precise fabrication of subsea jumpers and spool-pieces.   Traditionally
