Seiche is delighted to announce the appointment of Dan Hook as Non-Executive Director,
effective 2 January 2025.

Dan brings a wealth of experience and expertise in marine technology and innovation to Seiche. A
Naval Architect by training, he studied at the University of Southampton before embarking on a
diverse career encompassing fast vessel design, weight and stability analysis, and structural
engineering.

His passion for marine robotics led him to become a Chartered Engineer and establish ASV Ltd, a
pioneering company in the development and construction of unmanned surface vessels.
Following the sale of ASV Ltd to L3 Harris, Dan served as Chief Technology Officer at Ocean
Infinity for four years. He now leads RAD Propulsion, a company dedicated to advancing
technology for electric and smart boats.

In addition to his industry roles, Dan has contributed significantly to marine science as a Non-
Executive Director of the National Oceanography Centre over the past six years.

We are thrilled to have Dan on board and look forward to the valuable insights and leadership he
will bring to Seiche.

No matter what stage of your career you’re at, there’s something for everyone with our wide range of training courses.

We are pleased to announce that David Hedgeland has joined Seiche Ltd in a new Associate Director role on a part time basis. In this role, David will provide invaluable technical advice and guidance on underwater sound, marine monitoring, technology, and communications.

David has over 30 years of experience in the offshore energy industry, initially working offshore implementing seismic surveys, followed by over 20 years being engaged in international scientific and regulatory discussions related to underwater sound emissions from both traditional hydrocarbon and more recently renewable energy offshore activities and potential interactions with marine species and habitats.

David’s wealth of knowledge and industry insight will be a tremendous asset as we continue to drive innovation and excellence in marine monitoring and environmental stewardship. Welcome aboard, David!

Exciting News from Seiche: Partnering with Ocean Winds on the Moray West Offshore Wind Project!

We’re thrilled to share some great news: the first wind turbine has been installed at Moray West! It’s been an incredible journey for us, with months of hard work from our dedicated team. Together, we successfully monitored the installation of 62 monopiles for the offshore wind farm in the outer Moray Firth, Scotland.

But that’s not all – our involvement extended to comprehensive noise monitoring during installation. We meticulously analysed the data, providing detailed analysis and reporting every step of the way. This project truly reflects our dedication to long-term noise monitoring and our ability to tailor solutions to fit our clients’ needs.

Stay tuned for more updates as we uncover fascinating insights from the data collected during this project!

Launched at Oceanology 2024, our Real-Time Sound Measurement Buoy is a remote monitoring system that can collect, measure, process and transmit noise monitoring data in real-time.

Our RTSM buoy is a lightweight, compact and scalable solution to collecting noise monitoring data. Data is collected in real-time via a hydrophone deployed beneath the remote buoy, making the set-up, management and collection of data seamless in real time.

Applications include:

• Monitoring of offshore pile driving noise
• Real time monitoring of compliance with noise limits
• Live management of acoustic emissions during piling

Exciting News from Seiche Group!

We’re thrilled to announce that we’ve been awarded the prestigious SafeContractor accreditation! This achievement reflects our commitment to prioritising our processes and maintaining the highest standards to quality, safety and sustainability.

The Alcumus SafeContractor Certification demonstrates to our clients and partners that they can have complete confidence in our ability to deliver projects with the utmost attention to safety and ethics. It also reaffirms our commitment to maintaining the highest industry standards, which sets us apart as a reliable and responsible choice in our sector.

A huge thanks to everyone who contributed to this certification at Seiche.

Tune in to live recordings of underwater sounds captured by hydrophones nestled on the seabed at Middelfart, Denmark. This marine protected area is a bustling hub for harbour porpoises, and a collaborative effort between Aarhus University, Naturpark Lillebaelt, and Seiche is bringing real-time monitoring of porpoise activity and ambient sound levels.

Our mission? To unravel the mysteries of why this area is pivotal for porpoises, how their activity ebbs and flows over 24-hour cycles and throughout the year, and the impact of human activities on their behaviour. Using cutting-edge software, we remotely access and manage the system online, with audio and visual feeds streamed directly to the Seiche YouTube channel.

The displays vary depending on how researchers are viewing the data: you may see a spectrogram of ambient sounds, or a map with the tracks of larger vessels (AIS reports), or you may see a click detector display, where porpoise clicks are automatically displayed as red triangles. The audio you will hear blends low-frequency background noises with high-frequency porpoise clicks, that have been dropped down into our hearing range by signal processing techniques (the audible output of an envelope detector).

It is with great pleasure we can announce that Seiche Water Technology Group (SWTG) consisting of Seiche, Ashridge Engineering and Autonaut USV, have reached another major milestone in the development of the Group. On Thursday 18^th May SWTG were informed of our success in achieving the standard required for ISO 9001:2015 (Quality) and 14001:2015 (Environmental) Certification.

We are delighted in sharing the great news with our customers and followers, in recognition of all the hard work and dedication that our teams have shown in reaching this achievement.
