The data shows the ability for the system to detect potential UXO at considerable distances, enabling the platform to fly higher, or the water to be deeper.

The kit is already in the field collecting cable landing data using nadir and oblique photogrammetry techniques to ensure full coverage of the cliff line.

Throughout the campaign, we will acquire high resolution and high-quality bathymetry, backscatter, and side scan sonar data to allow for the ongoing monitoring of the seabed conditions. This includes seabed mobility, scour and cable free span, and exposures at both sites, covering all Wind Turbine Generator (WTG) locations, Inter-Array Cables (IAC) routes, and the Export Cable Route (ECR) at Kentish Flats.

Spectrum 3 is a Bureau Veritas Classed MCA Category 2 coded workboat and has been purposefully adapted to operate as a dual–purpose survey/crew transfer vessel, combining fast transit speed with a stable survey platform.

We can't wait to get started! 

The structures are being installed for the protection of the black-legged kittiwake throughout the construction of the Hornsea Three offshore wind farm, making this project the first of its kind.

Operations include:
 

• Boulder clearance surveys
• Scour assessment surveys
• Pre & post jack up surveys
• Cable depth of burial surveys
• Dredge monitoring

This system utilises RTK positioning with the latest MFAM™ caesium magnetometer technology from  Geometrics Inc. , sampling data at 1000 Hz, making magnetometer data acquisition over these shallow intertidal waters areas faster, more accurate and easily accessible.

Located in the Thames Estuary, London was a Second Rate ‘Large Ship’ built in Chatham in 1656 during the Interregnum. She is known for having formed a part of the English Squadron sent to collect Charles II from the Netherlands and restore him to his throne in an effort to end the anarchy which followed the death of Cromwell in 1658.

The London was blown up accidentally on passage from Chatham in March 1665. Approximately 300 people are thought to have died.

We are proud to continue providing survey support for Wind Farms on the North-East Coast of England.

Once completed Borssele will be the largest offshore windfarm in the Netherlands

Paul Duncan, Ørsted Geoscience Construction Manager for HOW02 said: “We are pleased to be working with UK-based Spectrum again. The benefits of having a dedicated survey vessel on location is that it will provide the necessary support for our construction teams who will be working across the project from nearshore to offshore.”

Jess Hanham , Spectrum commercial director said; “The contract award continues Spectrum’s excellent reputation in supporting major offshore wind farm construction in North-Western Europe. We are delighted to secure another long-term contract allowing us to further invest in new technology and our highly skilled work force.

Spectrum look forward to continuing to provide their services in support of the offshore wind industry and working closely with Ørsted and their Geoscience team”.

Hornsea Two is set to become the world’s largest offshore wind farm once complete, providing green electricity to well over 1.3 million homes once complete.

During the COVID-19 Pandemic, Spectrum are proud to be working on key infrastructure projects. 

Built in 1919, the SS Spaarndam was a passenger/cargo ship. On 27th November 1939, while en route from New Orleans to Rotterdam, she struck a mine. She was manoeuvred onto a bank and set on fire. Seven lives were lost.  

This unique vehicle was mobilised with our UAV navigation technology alongside other equipment. Combined with a traditional, vessel based multibeam element provided by Spectrum Geosurvey, this allows us to seamlessly survey the entire intertidal zone; a region that is notoriously difficult to access!

The Spectrum 2 will offer a wide range of services including hydrographic and geophysical survey, crew transfer, oceanographic monitoring and more! If interested in the services we’re able to offer feel free to send us an enquiry email at: info@spectrum-offshore.com.

Spectrum have closely worked with London Array over the past 5 years to provide the highest quality geophysical datasets and crew transfer support services to ensure the smooth operation and performance of one of the World’s largest windfarms.
Jonathan Duffy, General Manager of London Array said:

“The team at Spectrum Offshore have had a longstanding involvement with London Array and I am pleased the relationship is now set to continue for a further five years. The company will be providing a range of high quality services to support our Operations and Maintenance team, from high resolution bathymetric surveys to crew transfer. Their ongoing support will help ensure the continued success of the wind farm.”

We look forward to working closely with London Array over the coming years. 

Spectrum will utilise their geophysical and hydrographic expertise to provide a shallow water dataset consisting of high-resolution multibeam echosounder, backscatter, magnetometer and parametric sub-bottom profiler.

Hornsea Project One is located 120km east of the Yorkshire coast, and will become the world’s largest offshore wind farm when it becomes operational, expected to be in 2020.

The survey was conducted using the Njord Lapwing , which Spectrum Offshore have mobilised for Ørsted with their multibeam echosounder and sub-bottom profiler systems to support the construction phase of the Walney Extension Offshore Wind Farm.

The multibeam survey was conducted using the Foryd Bay , which Spectrum Offshore have
mobilised with a multibeam echosounder and USBL system.
