Offshore / Maritime
The maritime and offshore industries have their own specific requirements. Technotron's control and energy systems are designed to cope with these unique demands. More than in any other sector, our designs must allow for the effects of water, wind, weathering and salt. As in all fields, operational reliability is an absolute prerequisite for any successful design.
See here some realized projects offshore/maritime:

Ampelmann Iceman
The Ampelmann is the perfect system to create a safe gangway between a ship and a static offshore object, such as an oil platform or wind turbine The Ampelmann compensates the active motion of the ship. A platform with gangway is mounted on hydraulic cylinders. A gyro sensor receives a signal which serves as a reference for controlling the hydraulic cylinders. This adjustment needs to occur fast enough to compensate the motion of the ship and keep the platform stable and still regardless of the movement of the ship. Technotron developed an extended temperature version of the Ampelmann called the Iceman, commissioned by our partner Hydrauvision. The Iceman is built according to classification society DNV GL standards and can be used in regions with temperatures as low as -40°C. The Iceman will predominantly be used in the polar regions.

Control console Hydraulic Pump Unit (HPU) and two hose-reel drives
In close cooperation with the client, Technotron designed and constructed two consoles for use in the offshore industry. The consoles were intended to operate a Hydraulic Pump Unit (HPU) and two hose-reel drives, connected in turn to five hydraulic tools. These tools are operated using joysticks on the console. The HPU incorporates a Siemens S1500 PLC, which uses a profinet (process field net) to communicate with a Siemens ET200SP remote IO station and a Siemens comfort panel in the console. Both hose-reel drives are equipped with a spooler to distribute the cables over the reel. The hose-reel drives and spoolers are operated with joysticks on the console. The hose-reel drives can be operated synchronously. The spoolers can also be driven automatically. To facilitate this, both hose-reel drives and spoolers are equipped with encoders that are connected to the PLC. The HPU can be started either locally or from the console. The controls are constructed in such a way that, in the event of a failure in the PLC, the complete control process can be undertaken manually. Technotron was responsible for this project from start to finish, from design of the control system and construction of the control panels to installation of the electronics on location.
