Seamor Marine Debuts New ROV with 3km Capacity

of draining the tunnels for inspection,” said Iván Parra, Civil Engineer at EISA. “The operation will now be completed with a very small environmental footprint using Seamor technology.”The inspections required a deep-water ROV, which is why SEAMOR paired the 3-kilometer fiber optics tether with its Chinook ROV. Able to dive to 600 meters (2,000 feet), the Chinook ROV is equipped with a sensor skid carrying two Imagenex sonars: the 965A digital multi-beam imaging sonar and the DT360 multi-beam profiling sonar. These sonars are operated simultaneously using an Ethernet switch

Transmark Subsea Acquires WiSub

Transmark Subsea announced on Tuesday it has acquired fellow Norwegian underwater environment company WiSub.Transmark Subsea manufactures cable systems for distribution of electrical signals, power and fiber optics to the offshore subsea industry, WiSub supplies patented flexible wet-mate pinless underwater connection systems. Both companies have been key equipment and service providers to underwater intervention drone (UID) docking stations since 2018. This convergence of mature cable and connector manufacturing and design with innovative wireless underwater power and data transfer systems

its patented mooring technology to design a new lightweight, fiber optic Stretch EM Cable that will be used to tether communication gateway buoys.  To date, there is not a mooring cable on the market that can strain as the communication gateway buoy moves on the surface in wave action without the fiber optics becoming damaged or compromised.  Communication buoys are provided by the U.S. Navy, NAVFAC, NAVSEA and SPAWAR and are important, because they provide multi-path transfers between the ocean an atmosphere in support of Fleet operations.EOM Offshore, LLC was established in 2009 to commercialize

environmental challenges.   Sonardyne also points out that lines of communication are not point-to-point connections, but that they rely on multiple systems working together, operating in different mediums and changeable environments and with varying bandwidths across the internet, linked via fiber optics, satellites, short-wave or local wifi networks, acoustic modems, optical modems, Ethernet connections and LANs, with a multitude of data formats, protocols and operating systems that engineers have to somehow splice together to provide the seamless connectivity expected by users. Thus the main

of manufacturing challenges which required extensive prototyping, testing and building of specialized equipment. Today, South Bay Cable operates numerous production lines that can produce synthetic cables with strengths ranging from a few hundred pounds up to a quarter million pounds. The advent of fiber optics allowed the elimination of heavy signal and communication components which also helped further reduce cable weight. These advancements in materials and processing allowed South Bay to design and produce cables suitable for operation at full ocean depth in lengths exceeding 10 kilometers.

material begins to degrade.    “The data on cable failure over fifty years indicates that 70 percent of failures are based on corrosion, abrasion and third party impact. Therefore, the failures work from the outside inwards which are undetectable by current PD monitoring and internal fiber optics methods.    “When cables fail, they need to be replaced. So, teams of engineers will then spend on average two weeks locating the cable and point of fault. They will then either join the needed piece of the cable via an iron collar to the remaining healthy cable or simply install
