Ransomware: The IT Danger on the Horizon

aggressive mode of attack?Over the last 10 years, the integration of operational technology (OT) and information technology (IT) systems in the maritime environment has accelerated dramatically. Onboard ships, modern network technologies allow for greater control and monitoring of engineering and mechanical systems, leading to increased reliability and efficiency for vessel operators. For ports and other infrastructure hubs, many key industrial systems now have physical connectivity with the outside world through integration with internal IT-based control systems.

depend on the circumstances. They may either be able to wait for rescue or, if the circumstances require it, to evacuate via an emergency escape system. The SET is a diving bell equipped with a replica submarine escape tower. This escape training module is moved vertically in a water column using mechanical systems which allows comprehensive training to be carried out in a perfectly controlled environment. Through this new partnership, JFD will be able to offer the SET solution, or variants, to customers thereby broadening its escape offering. JFD can also tailor its provisions to customers’ unique

or unmanned surface vessels) and just another tool. Back then, the idea of using a robot boat to do hydrographic survey and map the sea floor was hard, if not impossible. Now you can hire a boat ready to do that.”Since 2002, the evolution of sensors; GPS, heading sensors, micro-electronic mechanical systems (MEMS), helping vessels to understand where they are, has been important, says Manley, as well as the development of payload sensors. “We have had multibeam sonar for a long time, but it was expensive, complex, very large and typically built into the hull of a ship. Those instrumentation

Ocean Autonomy: Norway to the Fore

, shipping or ocean science, the range and capability of subsea equipment and ancillary and support systems is expanding by the day, aided by developments in ICT, nanotechnology and even biotechnology (for the snake motion used by Eelume, for example), including new materials, microe-electric-mechanical systems, and big data. As an example, systems are being developed which could sense and distributed forces along the body of an underwater vehicle, in order to compensate for or reduce drag, says Sørensen. He also cites micro to macro actuation and sensing, and machine vision systems using hyperspect

an ROV using Lego Mindstorms, a platform produced by Lego to develop programmable robots based on Lego building blocks. Each version of the system includes an intelligent brick computer that controls the system, a set of modular sensors and motors, and Lego parts from the Technic line to create the mechanical systems.   The winning team from each regional event will receive a Think Kit from The Smallpeice Trust, with all the tools needed to run an in-school challenge and build a floating wind turbine. They will travel to Aberdeen, the Global Centre of Excellence for Subsea, for a morning of company

of the globe, eventually returning to its home port of Plymouth.   Silicon Sensing is to provide a package of support to help turn the MAS400 concept into reality. In addition to sponsorship of the project, Silicon Sensing will supply its latest precision MEMS IMU (Micro Electro-Mechanical Systems - Inertial Measurement Unit), the DMU30, to provide the inertial sensing data within the electronic autopilot to help guide MAS400 during its ocean adventures. MSubs and Silicon Sensing have been collaborating on the evaluation of DMU30 for future INS-based surface and subsea navigation solutions

SST, with a Navy team, designed and installed the STAFAC mooring and mechanical systems, including a large A-frame (Figure 3) and has conducted all of the operations for maintenance and upgrades since 2008. For this recent upgrade task, SST prepared all the planning and engineering required for the recovery and installation of the array as well as at-sea operations including the
