Our team is made up of people with different personalities and career ambitions. We pride ourselves on providing unique career development opportunities for every individual, which is both challenging and rewarding, as well as providing a clear sense of purpose.

Our people matter, so ensuring their safety is our number one priority. We are certified to ISO-9001:2015 Quality System and ISO 45001:2018 Occupational Health and Safety Management Systems Accreditation and have adopted technology to ensure safety information is always accessible. Our focus, commitment and continuous training has resulted in maintaining an enviable safety record.

Our team has many years of experience conducting hydrographic surveys and metocean monitoring services. Our underpinning philosophy when working with clients is to be trusted specialists, deliver critical insights, and go the extra mile where we can. This has been our mantra since we were established in 2008. It is this approach that makes us different. No matter what the project, we work in close partnership with all our clients.

Our stringent internal quality assurance processes ensure critical analysis throughout the project to ensure we remain on budget and are delivering the desired outcome to the client.

All PHS projects are overseen by a Certified Professional Hydrographic Surveyor Level 1 (CPHS1)/Project Manager. Certification to Level 1 is the highest attainable level of professional hydrographic surveying certification, which provides you with complete confidence in our thorough understanding of the theoretical aspects of hydrographic surveying, as well as the complexities of maintaining quality assurance principles.

We know that the success of any project is in preparation and planning. Before commencing plans for your project, we listen to your requirements to ensure our operations achieve the results you expect. Our passion is to create value which means we are continually striving to redefine our standards of excellence.
