Marine survey boats require engines with low noise and vibration

They “see through” the sea floor and into the layers of sediment and bedrock below, as well as locate old airplanes from World War II. Clinton Marine Survey carries out many types of underwater surveys. In order for the hydrographic monitoring equipment to record accurate results, Clinton Marine Survey’s vessels require engines with low emissions along with minimal noise and vibration.

Clinton Marine Survey conducts geophysical and hydrographic mapping

Clinton was established in 1989 with the goal of offering all types of geodetic measurement and measurement-related reporting, both on land and at sea. During 2014, a separate subsidiary, Clinton Marine Survey AB, was established to further continue their growth and investment in the areas of geophysical and hydrographic mapping. Today, Clinton Marine Survey carries out various hydrographic assessments, such as bathymetric surveys (on ocean and lake floors), seismic monitoring, remotely operated vehicle (ROV) inspections, unexploded munitions (UXO) identification, magnetometer surveys (identifying magnetic material or fields), habitat mapping, and cable tracking. These functions and tests are executed for the authorities in Sweden, Finland and the UK, as well as for international energy companies.

The Sweden-based company operates in the seas across Northern Europe and owns a number of vessels specifically designed for working in extreme shallow to medium water depths.

A low noise and vibration profile both in the water and vessel

Clinton Marine Survey’s largest vessel, M/V Northern Wind, operates around 250 days a year, which results in some 3000 operating hours. The vessel often operates for days on end, which requires reliable and high performing engines. It is crucial to achieve high uptime, since a production stop would be very costly, for both Clinton Marine Survey and their customers. Since Clinton Marie Survey works with acoustic instruments, they need engines with low noise levels. Another top priority for the company is to use engines that are gentle towards the environment. By using the latest technologies, when it comes to both engines and the sonar equipment, they are able to perform their work both faster and more efficiently. By operating faster they use fewer resources during the projects, which is beneficial for both the environment as well as their customers.

As we work with acoustic instruments, a low noise and vibration profile both in the water and in the vessel are crucial for us. The less ambient noise we have, the better the instruments work”, says Johan Lindskog, Master of Clinton Marine Survey’s Northern Wind vessel.

Lower fuel consumption as well as less smoke and smell on the aft deck

When it was time for Clinton Marine Survey to repower M/V Northern Wind, they were looking for engines that could increase the efficiency, lower the fuel costs and ensure high reliability and uptime. They chose to power the vessel with two Volvo Penta D13 500 hp engines and matching aftertreatment system, to meet the International Maritime Organization’s (IMO) Tier III regulations.  

Volvo Penta’s solution has been good,” says Johan Lindskog. “It’s a fully automated system, and basically we do not notice it is there, which is what you want in our business. What we have noticed, however, is lower fuel consumption, lower noise, and less smoke and smell on the aft deck. We have also gained more driveability through new control functions. The new installation has given us better possibilities to drive at both lower and higher speeds, which is really good. The new engines allow us to conduct our surveys faster and with higher precision than before, which enables us to deliver a better product to our customers.“

Volvo Penta’s IMO Tier III solution is easy to use and maintain

IMO Tier III will stipulate a reduction in emitted nitrogen oxides (NOx) of around 70 percent, depending on engine size, when compared to current IMO Tier II levels. Volvo Penta’s IMO Tier III concept offers flexible installation to suit each customer’s needs. It is designed for ease of use and maintenance and is a solution for global requirements both in terms of providing optimum power with low fuel consumption and reduced emissions. It is robust enough for the most challenging operations, and the reduction in emitted nitrogen oxides means that our solution also helps to protect the environment.

It is an important step for the marine industry to cut pollution levels,” says Johan Lindskog. “To minimize the environmental impact is an important part of our company profile. We always strive to use the latest technology to deliver a superior product and be on the cutting edge in our field. Volvo Penta’s solution is a big part of making this possible. This benefits us, our clients and, of course, Mother Nature.
