EMHA Technisch Bureau is one of the most complete and leading companies in the Netherlands offering a full-range of alignment services. We are known as complete solution provider since we can do measurements, alignment, fastening, problem-solving, engineering and reporting. We are able to maintain our leading position by constantly investing in the most advanced laser - and measuring equipment. Even more important is our team of highly skilled, specialized technicians, at your service to achieve optimal results! Good installation and alignment of rotating machinery is crucial to achieve an optimum performance with minimal costs. Misalignment will cause problems such as vibration, bearing and coupling failure and mechanical wear to different parts. A perfect alignment of your rotating equipment will result in maximum installation efficiency, low maintenance frequency and costs, less energy consumption and reduction of vibrations and wear. For the shipbuilding industry we can also perform the alignment of propeller shaft and gearbox, the alignment of bearing journals in relation to stern tube, measure the flatness of a slewing ring bearing and many more.
The engineers from EMHA Technisch Bureau are equipped with advanced 3D metrology and laser tracking tools. With these tools we are able to do much more than equipment alignment. We carry out 3D measurements quickly and accurately with use of the newest technologies. Our service technicians have years of experience in measurement in shipping Industry. They can determine anchor bolt positions, monitor strategic control points, and hence even do reverse engineering of complete installations. All with the highest degree of accuracy available. Additionally, our team is able to assist with the inspection of ship parts and components and with installation of these components. Furthermore, laser scanning obtains the as-build condition of the ship and allows for easier repair or future restoration.

VIBRATION MEASUREMENTS SOME VERY COMMON PROBLEMS THAT WE CAN DETECT USING OUR VIBRATION MEASUREMENT SYSTEM:
Misalignments Disparity / Offset Damage to machine bearings Worn parts such as gears, belts, etc. Poor lubrication Overloading Clutch design Corrosion and cracks Resonance problems
With our machinery vibration measurement service we are able to provide a reliable indication of the condition of rotating machinery, while in operation. Vibration measurement data will help to detect problems that might be developing. By monitoring the condition of machinery, most developing problems can be detected even before they arise. Detecting defects in such an early stage will prevent further damage and minimize machine downtime. The required repair will be simpler, faster, and cheaper. Since almost any error or divergence in the machine sources a different level of abnormal vibration, our specialists are able to translate the measurement data to determine the actual, specific problem in a machine. Furthermore, our measurement data can also be used to prevent unnecessary maintenance, find causes of production quality problems, stop discomfort and even avoid a bad company image. Vibration data taken on a particular physical point and collected regularly over a period of time (Trending) supports us to build-up a history of the installation and itâ€™s waveform characteristics so changes can be detected, accurate physical explanations can be assigned and corrective actions taken accordingly.
CHOCKFAST EPOXY PRODUCTS
Specialized maritime epoxy compounds.
Chockfast Orange (chocking compound) Chockfast Gray (thin pour grout) Phillybond Orange (flexible sealant) Phillymastic TG-7b (LNG/LPG epoxy) Phillyclad 1775 (shaft coating) Repair Compound (fairing paste)
With Chockfast epoxy products, reliability is guaranteed on all types of vessels, offshore platforms, mooring buoys, oceanographic equipment, crane rails and other marine applications. EMHA delivers and uses proven products from the organization that developed Chockfast Orange, the reliable epoxy chocking system used to install more than 45.000 main propulsion engines plus auxiliaries over a 40 year period.
CHOCKFAST ORANGE (PR-610TCF)
CHOCKFAST GRAY (PR-610FR)
Is a specially formulated 100% solids, two component inert filled casting compound developed for use as a chocking or grouting material. CHOCKFAST is designed to withstand severe marine and industrial environments involving a high degree of both physical and thermal shock. The compound is nonshrinking and has very high impact and compressive strength.
Is a specially formulated 100% solids, two component, inert filled compound developed for use in chocking non-precisely aligned equipment or in setting anchor bolts in concrete.
Is a two component, epoxy paste, developed for sealing exposed edges of CHOCKFAST in stern tube applications. It is resistant to sea water and lubricating oils. It has good adhesive strength and flexibility over a wide temperature range.
Is an excellent general purpose, nontoxic laminating resin system for FRP application requiring rapid and thorough wet out. Excellent for use as a thin laminate protective coating over steel or other materials and in combination with glassfiber tape. PHILLYCLAD 1775 is the best solution for Propeller shaft coating.
Is a two-component, load-bearing, epoxy mastic specifically developed for LNG/LPG tank or container system installations where shimming or void-filling of supporting components is required.
Is a two component epoxy paste developed specifically for filling, smoothing and fairing applications on metals, plastics (FRP), wood or masonry. The smooth consistency and excellent non sagging properties of Repair Compound make it unexcelled for levelling rough or pitted plating, forming fillets and smoothing weld seams.

For more than 30 years EMHA is performing maintenance on metals and alloys with MultiMetall materials. These polymer metallic materials are professionally equipped to withstand the most difﬁcult conditions and are suitable for repairs, protection and reconstruction. Lloyds Register of Shipping certificate 301954 gives MultiMetall the qualification “good to exceptionally good”. MultiMetall is already applied successful on dry, dirty, oily or under water lying repair areas and has superior mechanical physical data to withstand constant load. The continuous compressive strength under load can be more than 160 MPa and MultiMetall is difficult to damage when attacked by acids, alkaline solutions, solvents, salts, gasses and other chemicals. We have massive experience in marine repairs.
Some examples: ¬ Repair of marine engine cylinder heads ¬ Sealing of cracked leaky welding seams at crankcase of a ship diesel ¬ Elimination of damages at a vessel’s propeller caused by cavitation ¬ Repair of the packing surface of an adjustable propeller ¬ Repair of cylinder liners ¬ Repair of cracks and apertures on a turbocharger ¬ Repair of cracked housing of a hydraulic pump in a steering gear
MECHANICAL CHOCKS EMHA Technisch Bureau delivers adjustable, self-levelling and reusable mounting chocks that can be used to mount rotating equipment. These mechanical chocks are a blend of cutting edge engineering and years of experience to produce a strong, stiff and elegant device to end machinery soft-foot.
Our mechanical chocks are manufactured with a special thread type called buttress thread. Unlike common thread types used in mechanical engineering, buttress thread has an a-symmetric design which comprises a 7째 top angle and a 45째 supporting flank. As a result of this thread design, the chocks are more mechanically stiff and have higher load bearing capacity compared to standard chocks with metric thread of similar diameter and pitch which uses a 2x30째 angle design. With years of experience in installation and foundation of machinery, EMHA Technisch Bureau is able to perfectly mount your machines on our chocks. However, if you like the mounting to be performed by own personnel, we can also advice and deliver the chocks only.
EMHA offers training courses in which different aspects of measurement, alignment, chocking, or grouting are covered. EMHA is able to provide the following training courses at our facilities or at customers’ location.
¬ Chockfast product training ¬ Chockfast classification calculations ¬ Rotachock product training ¬ Multimetall product training ¬ Vibration measurement training ¬ Shaft alignment training ¬ 3D measurement training ¬ Machine foundation design
