Success For Remote Commissioning Of Two AHC LARS Systems To Ennsub
Scantrol has delivered two AHC LARS control systems to Ennsub Deepwater Technologies to use on board their customer’s vessel Ceona Amazon. The systems were successfully configured and tested from the Scantrol offices in Bergen. — The remote assistance saves valuable time and commissioning costs for our customers, says managing director at Scantrol, Helge Hammersland.
The remote commissioning was made possible by the AHC Toolbox. iSYM Online offers remote support both onshore and at sea by connecting to the ship’s LAN via satellite. Before sea trial Dynatest is used in the factory to verify AHC performance based on recorded winch characteristics and simulated vessel motion.
The LARS systems were set up at Ennsub premises in the UK for testing and connected to a laptop. From the offices in Bergen Scantrol technicians connected to the laptop, finished the system configuration and performed a Dynatest to verify the AHC performance.
DYNATEST CURVE: Scantrol iSYM software running on the laptop with remote supervision was used to simulate several waves to ensure that the winch responded fast enough and was able to meet the speed requirements. This Dynatest curve shows the winch performing perfectly.
Ready for sea trial the Scantrol technicians connected to a computer on board Ceona Amazon to supervise the testing and assist with any problems during testing.

– Everything went very well. Though there are still some minor tuning needed, both systems worked fine and remote support was great from Scantrol’s side, says Oscar Espinar, general manager at Ennsub Deepwater Technologies.
Testing of the AHC system from the office not only saves Scantrol valuable time and resources but reduces commissioning costs for Our customers.
– This is possible because we have developed high quality test software and are well prepared for FAT and SAT, says Mr. Hammersland.
AHC TEST CURVE: Once the systems were installed on board, the AHC test confirmed the Dynatest results.

AHC increases the vessels` competitiveness
-“As the offshore markets slow down due to lower oil prices, we experience that more ship owners are looking at the opportunity to upgrade their existing deck equipment with AHC instead of buying new. Retrofitting of existing equipment to AHC is often a very cost-effective way to putting the vessel in a better position in order to get the limited number of new subsea operation contracts in the market,” Helge Hammersland, managing director of Scantrol, says.
Scantrol is currently analyzing several existing winches in order to determine their AHC potential.
–“Often, an acceptable heave compensation capacity can be achieved by just replacing the control system with an AHC control system”, Hammersland says, finding himself confident that this market trend is going to contribute to reduce the costs in the offshore industry.
-“We are very happy that Bibby HydroMap have chosen us for their AHC upgrade. The job has given us the opportunity to show what we are good for when it comes to retrofitting. I think we succeeded”, Hammersland concludes.
