Time has flown by since the successful installation of the AWS half-scale cassette demonstration project – the 100th day of testing has just been achieved. During the installation and test period 4c Engineering provided engineering and support services to AWS, including management of the marine operations, mechanical and electrical installation, SCADA design and implementation, HSE management and post-installation diving inspections.

Testing of the AWS device has been monitored remotely from our base in Inverness with regular trips to Orkney to carry out on-site inspections. We are now analysing the data gathered and will be reporting back to AWS with the findings.

This has been a great project to be involved with using our full range of skills from detailed mechanical design and FEA through to practical operations on site and on the water. We’ve learned a great deal about the AWS-III diaphragm and system performance and it’s been great seeing the AWS device operating in real world conditions.
