Diver core body temperature is transmitted wirelessly to Seatooth SWiCOM, a wireless underwater tablet so that diver core body tem- perature can be monitored. This information can be transmitted securely to a diver buddy using Seatooth wireless communications. A demonstration was held at a Department of Defense Special Op- erations Command event in Florida. ROVOP Receives Funds For Bigger ROV Fleet ROVOP Ltd., an independent operator of ROVs, will immediate- ly increase its fleet by 50 percent to meet ongoing customer demand following a funding boost of £56 million. Blue Water Energy and BGF have jointly committed to the funding that underpins ROVOP's ambitious future growth plans. The funding is financing an increase of the fleet to 24 ROVs, with the new assets being acquired from Tidewater in Hous- ton. Tidewater owns and operates one of the largest fleets of offshore support vessels globally. ROVOP focuses on the provision of ROV services to the oil and gas, offshore wind, telecom and power transmission industries. Along with ROVs, the company provides expe- rienced operators trained in house. Hacking Demo Shows Maritime Vulnerabilities Naval Dome has demonstrated the maritime industry's nightmare security scenario with a series of cy- ber penetration tests on systems in common use aboard tankers, con- tainerships, super yachts and cruise- ships. Test results revealed with star- tling simplicity the ease with which hackers can access and override ship critical systems. With the permission, and under the supervision, of system manufac- turers and owners, Naval Dome's cyber engineering team hacked into live, in-operation systems used to control a ship's navigation, radar, engines, pumps and machinery. While the test ships and their sys- tems were not in any danger, Naval Dome was able to shift the vessel's reported position and mislead the radar display. One attack resulted in machinery being disabled, sig- nals to fuel and ballast pumps be- ing overridden and steering gear controls manipulated. Another was able to alter draught/water depth details in line with the spurious po- sition data displayed on screen. The test ship's radar was hit in an- other attack, with success in elimi- nating radar targets, simply deleting them from the screen. At the same time, the system display showed that the radar was working perfect- ly, including detection thresholds. A separate controlled attack was performed on the machinery control system. In this case, Naval Dome's team chose to penetrate the system using an infected USB stick placed in an inlet/socket. The virus infecting ship systems can also be unwittingly transferred by the sys- tem manufacturer. ST
