How custom software development made EIVA the single supplier to a large survey company


'Clinton used NaviSuite for all our projects during 2016, and will do the same going onward. The strategy to use NaviSuite for hydrographic and offshore surveys has created a smooth processing workflow and increased competence for our personnel by using only one standardised software flow. The client will benefit from higher quality and more cost-effective operations in the coming projects.'

Challenge

For a long time, Clinton, a Swedish surveying firm, has used several different suppliers and platforms to perform its varied surveying work. And for just as long, this had been considered the ideal tack. However, the firm was realising that using multiple suppliers was causing more problems than it solved in the form of high maintenance fees, scattered knowledge, different support teams and support cases, and transition issues. Continuing to use multiple suppliers was not a viable plan; Clinton would need to streamline and standardise to be even more efficient and innovative going forward.

Choosing a single supplier is a leap of faith not undertaken lightly. Since Clinton is a large company with many varied and complex projects, from very large-scale surveys on the ocean to working with extremely shallow depths with complex water columns, no supplier perfectly met all needs out-of-the-box. In addition, the survey field is constantly evolving, and so the solutions must be constantly evolving too – which required a dynamic relationship with the supplier.

Solution

After a lengthy evaluation, Clinton chose EIVA as its new single supplier. Not only does EIVA have a strong software suite in NaviSuite that covers all stages of an offshore/shallow water survey, but EIVA had also demonstrated a very customer-focused approach – especially when helping Clinton in a timely manner when urgent issues arose, making sure the clients’ deadlines were met. 

In addition, based on their experience with EIVA’s custom development in the past, Clinton also knew that EIVA could show the same flexibility and dedication in helping to fulfil any unmet needs for Clinton’s projects.

Customised solution development

During the single supplier decision process, Clinton reached out again to EIVA to explore the possibility of certain custom developments. With Clinton supplying the requirements and EIVA supplying the development, soon, new custom surfaces were added to EIVA NaviModel to combat specific challenges that Clinton was facing. The experience in acquiring and using these surfaces did much to tip the scales in EIVA’s favour.

These surfaces were not the first custom development done by EIVA for Clinton, of course. Other projects included tools for squat tables, gap-finding, filtering, and more. Nor were they the last – one of the more recently developed of these tools was a new refraction slide tool.

The new slide tool for refraction has saved Clinton a lot of time and effort, and thus saved a lot of expense for the end client. It has also improved the end product. The refraction tool is particularly useful for Clinton when dealing with complex water columns (perhaps caused by a strong layering of freshwater and salt water), strong thermal layers in sunny weather, or even just when it’s not possible to get sufficient spatial coverage of the sound velocity sampling. Recently, the tool was used for a complex Norwegian river survey where the water was extremely shallow and the water column unstable – the successful completion of which ‘would not [have been] possible without [EIVA’s] effort’.

Result

Armed with these new tools, Clinton has used NaviSuite for all its projects since the collaboration started, including its recent project surveying the Bratten area in Skagerrack – a survey project over a much larger and deeper an area than most in Scandinavian waters. The assignment involved charting a 1206 km2 area, and in the process, charting the deepest point in Swedish waters at 560 m. This was done quickly and accurately despite bad weather and deep water. EIVA makes sure that as Clinton’s projects evolve and progress, the software does too, so that needs are promptly met both now and moving forward.
