We are expanding our survey team and now need a Junior Hydrographic Surveyor to join the team.

Key to our operations, the junior hydrographic surveyor will focus on the collection of high-accuracy marine data across the UK and Europe for critical sectors including renewable offshore energy, ports and harbours, and civil engineering. The successful candidate will be responsible for conducting accurate site characterisation, managing site investigations, and producing concise technical reports that meet stringent industry standards.

Hiring: Junior Hydrographic Surveyor

CMS GeoScience is supporting the incredible work of Ruth Russell SEO, who is over 720 swims into her 1000-day Daily Dip 4 Dave challenge and has raised £40,000 so far for Neuroendocrine Cancer UK.

We’ve pledged to donate £1 for every metre of core we collect this year. Every successful project we complete is contributing directly to raising vital funds for those affected by Neuroendocrine Cancer.

We’re also proud to be the official badge sponsor for the National Daily Dip 4 Dave Day! This mass cold-water dip takes place on Saturday 11th October, at Gylly Beach in Falmouth and around the world.

The 2025 Daily Dip 4 Dave also introduces the Challenge Cup, a competition open to businesses. The Cup will be awarded to the team that takes part and raises the most money. Register here: https://lnkd.in/gzhixWFG

We can't wait to see everyone brave the cold for this brilliant cause.

A massive thank you also goes out to our friends at Datem Ltd. for their incredibly generous donation of £1,000! Aaron Bromley from Datem Ltd. was down in Cornwall on holiday this week and even popped in to see us!

Cheers Aaron Bromley and Datem Ltd. for joining us in supporting this important cause.

We believe that every metre and every dip can make a difference.
Take the plunge and join us in supporting Neuroendocrine Cancer UK!

Our team aboard MV FlatHolm got a surprise visit off the South Coast yesterday. We had a front-row seat to an Maritime and Coastguard Agency HM Coastguard training exercise.

While it's not every day you get a fly-by, it's a great reminder of the essential work they do to keep our waters safe. We were happy to play a a small part in their training and witness their vital work firsthand.

Earlier this week, we successfully undertook a geotechnical survey in the English Channel for a new client. Once completed our crew and the MV FlatHolm made their way towards the River Thames to start work on an important infrastructure project for a longstanding client.

Following on from this, the team will be heading off to carry out more site investigations working their way along the English Channel and South Coast. After a well-deserved short break, we'll be back in action with a busy schedule of geotechnical surveys across the English Channel, Bristol Channel and East Coast later in the Autumn.

As we move into October, we will come inland to a undertake a specialist geotechnical project where we'll be deploying a unique in-house solution on an inland body of water in a challenging environment, so stay tuned for updates.

Momentum continues as we head into a busy autumn of projects

Both projects involved the collection of high-quality data using multi-beam bathymetry, dual channel sidescan sonar, boomer, and magnetometer. This work is critical to understanding seabed integrity and composition, providing the essential insights needed for our client’s projects.

Despite encountering some tough conditions in the English Channel, our team persevered, ensuring the job was completed safely, on time and to the highest standards. We worked 24-operations from our own vessel, MV FlatHolm.

The successful outcome of both jobs is testament to the expertise of our crew and their commitment to our core values of safety, accuracy and integrity.

We’d like to extend a thank you to all those involved, and we look forward to our next geophysical job.

Operating from Seafast’s 33m offshore service vessel, the Isle of Jura, our team conducted vibrocoring at up to 60 locations, working 24-hour operations, 100nm offshore.

The success of this project was a direct result of meticulous planning, good collaboration with the vessel operator and crew, and our unwavering commitment to operational safety and the highest quality results. Despite challenging weather conditions, our equipment performed flawlessly, delivering crucial data on time and with no lost-time incidents.

CMS GeoScience is pleased to announce the recent purchase of a new site in Falmouth, Cornwall, marking a significant milestone in the company's ongoing growth and development. This strategic move underscores our commitment to enhancing our operational capabilities and strengthening our presence in the region whilst also enabling us to support the development of renewable energy and floating offshore wind in the southwest and Irish sea.

 

The Gables will support our operations and enhance research and development of new equipment. The site is being updated to ensure it can support our ambitious growth plan and exciting strategy. We're already working on building new laboratories and storage facilities for our equipment, ensuring that we can continue to deliver the high standards of service and innovation that our clients have come to expect. The new facility will serve as the headquarters for our management, administrative and survey teams supporting our future growth.

 

We will continue to maintain our long-standing presence in Lowestoft, with our warehouse and dedicated berth, which remains a fundamental part of our operations. Our vessel, MV Flatholm will continue to operate from this location, moving between the East Coast and southwest giving us the unique ability to operate efficiently along all sides of the UK and Europe.

 

We are proud and excited to take this significant step forward which demonstrates our dedication to both the development of CMS GeoScience, our people and the services we provide as well as our long-term commitment to the area. This substantial investment in our infrastructure will enable us to better serve our clients, support our team, and contribute to the continued success of our company.

Our Marine Geologists, Rory Bardner and Owen Sweeney, travelled to Banbury to attend Equipe Group’s comprehensive Soil Description Workshop (BS5930). Guidance was given by several leading industry experts, and it was a great opportunity for them to refine their logging skills that they use on a day-to-day basis here at CMS GeoScience.
