The effectiveness of the ship's screw would determine drag and fuel consumption of the vessel. Therefore, our team is able to deliver the highest standards of screw maintenance for shipping companies and vessel owners by ensuring that cavitation wear avoided / worsens, and to achieve savings. S.M.U performing propeller polishing on all types and sizes of vessels in all Danish ports and offshore. We may be the only company in the Nordic region, achieving a surface roughness at the screw polishing, there are far better than Rubert Gauge "A" (the best result with a Rubert Gauge "A" is 1.00 micron Ra (CLA) and we can polish the surface down to a roughness of 0.40 micron Ra (CLA)). By getting carried screw polishing can achieve the following benefits: Up to 4% fuel savings, depending on the fouling of the propeller. Lower load of the main engine. Reduced CO2 emissions resulting from fuel savings. Propeller polishing performed under water, giving a better result than polishing in dry dock.

We provide hull cleaning of all types of vessels of all sizes and in all Danish waters. We can carry out cleaning with two different systems: An innovative and innovative hull cleaning system, operated from the surface. The system was developed and patented by SMU in 2013. The system is both more gentle on the ship's surface and the environment, and it is far more efficient than conventional systems. This is because the system does not require divers and that it can clean a larger area faster. ROV system is suitable for vessels of over 250 m. LOA. System 2 is a conventional brush system which is operated by divers in the water. We offer different types of brushes, depending on the vessel surface and fouling. Brush system is particularly good for hull cleaning of ships of less than 250 m. LOA.

An in-water survey is when one makes a diving inspection of a vessel's structure under water. We carry out both planned surveys, for example. in combination with a classification, and acute inspections, for example. may become necessary as a result of the grounding. The inspection carried out by a diver who inspects the vessel thoroughly. If there is a classification inspection also requires a supervisor and a surveyor from the classification. Once we have completed an in-water survey both you, and possibly. classification society, receive a diver video (CCTV), a report and, if necessary. other documentation of your choice.

Here at S.M.U. we perform professional Photo and video inspection, and provide documentation requested by the customer. If the customer wants it delivered image documentation in a detailed report. We carry out both planned underwater Photo inspections, for example. in combination with a classification, survey, sediment / soil conditions, sprinkler tanks, Underwater construction both before and after diving. As well as acute inspections, for example. may become necessary as a result of grounding or damage to port facilities, submarine cables or pipelines. Several of our customers take advantage of us to inspect the work of other divers, as well as to document and advise on the future projects.

We can perform thickness measurement to steel structures such as steel sheet pile. The results found are delivered to the customer in a detailed report.

We have here with S.M.U. many years of experience with the installation of anodes on the quay, poles, ships and steel constructions. We perform both new installation and replacement of anodes, although it is as a subcontractor or complete contract, for companies, contractors or the public. S.M.U. advise and inform customers like about Cathodic protection, and if desired provide a quote.

We are at S.M.U. very proud of our skills in underwater welding, where we always deliver the best possible result. We have over the years welded subjects in most applications, so are therefore able to perform all kinds of welding applications.

We have much experience in setting up base security in ferry berths. We ar both cast-base and zoned gabionger.

S.M.U. welcomes visitors on tasks as the main contractor for both small and large tasks. We have experience and expertise to handle all aspects of a contractor job.

S.M.U. has repeatedly advised customers before, during and after diving. We can among others. Advise on opportunities, security, economy and duration. We advise and inspect other dive companies work after a completed task as part of quality assurance.

We can offer an effective solution for cutting concrete, which through. A sub-contractor can cut through large items concrete using a wire saw. The saw can be modular so there is almost no limit to the size or thickness of the items to be cut.
