Your in-road into the subsea industry Global Marine Systems has launched a new Remotely Operated Vehicle (ROV) training facility designed to meet increasing demand for experienced ROV-trained personnel within the subsea industry. The ICMA (International Maritime Contractors Association)-aligned courses and certificate of competency scheme are run from Global Marine’s Portland, UK, depot and in the surrounding waters, combining theoretical work with practical experience. It is open to both Global Marine employees and individuals and com- panies throughout the industry and can be tailored to meet an organisation’s exact needs. Global Marine has a dedicated Sea Eye Falcon, a Trojan Work Class ROV, and The AU180SPE coil winder and static decoiler SV2 is a simple to use machine for turn-to-turn winding of normal or coated ductile wires, annelead or zinc plated iron, copper and zinc aluminium with diameters up to 5.0mm. Coil dimensions (standard pick up coil) are a maximum outer diameter of 340mm, an inner diameter of 200mm and a width of 150mm. Weight can be up to 50kg. Wire-guide pitch electronic adjustment can be simply changed by setting the desired pitch on a special keyboard. This system makes the machine extremely flexible and rapid for winding any diameter of wire with maximum precision. Simple to use from Collari Edore

an Open Frame Sprint at the depot, to give trainees hands-on experience with equipment they would be using in their future roles. There are also a number of workshop activities that take a trainee through practical experience of electrical, electronic and hydraulic systems to include an operational sonar and cameras to a full reterm of an armoured umbilical. In addition, theoretical coursework is complemented with a simulator used for computer-based training and scenario modelling. These methods develop trainees in the role before going offshore as part of a team on an ROV or Plough System. “This real world ROV training facility will help to fill the gap that exists in the market for trained ROV personnel and act as a training portal for those small operators who do not have the means The winding stops when the desired coiled wire numbers of layers is reached, and already positions itself for the next coil. An automatic pneumatic system extracts from the winding drum the finished bounded coil and carries it out for easy removal. The coil winder is combined with the unwinder-static decoiler model SV2 that can be easily combined with all coil winder models.

to have their own in-house scheme,” said John Davies, manager of the training programme. “By offering training which is flexible, informative, and run to industry recognised standards and best practice, we can ensure that trainees have the right skill sets to contribute to advances in the subsea industry.” course, trainees are evaluated through exams, assignments and practical assessments and upon completion they are also entered into the Global Marine Certificate of Competence Scheme which continues after the course ends and ensures that there is consistent training throughout their career.

The system completes the spectrum of disc lasers, ranging from 60 to 3,000 Watt, that are offered by Rofin. Rear side contacted solar cells eliminate the otherwise necessary front side strip lines and in this way enhance the solar- active surface and thus cell efficiency. The entire interconnection of solar cells into modules can be realised without any connections from the front to the rear side, increasing packing density and reducing costs. With the MWT method (metal wrap through), the soldering lines which are required for the interconnection within the module are positioned on the rear side of the solar cell. For this purpose, 25-50 holes with a diameter of 300-500 µm are drilled in a grid pattern on one solar cell and then filled with conductive material. If the entire contacting of the emitter layer is located on the rear, approximately 15,000 holes with a diameter of 60-70 µm are drilled (emitter wrap through method – EWT).
