Originally founded in 1952, Nicol & Andrew (or as we are sometimes known Nichol & Andrew or even Nicole & Andrew) was the first company of its kind to carry out in-situ machining and repairs on marine propulsion units such as diesel engines.

Our in-situ marine technicians travelled around the world carrying out emergency repairs to damaged main engines, tailshafts, propeller shafts and associated marine equipment. Our customers came to expect a very rapid response and total dedication to getting the equipment back in running order in the minimum possible time. We became accustomed to our teams working around the clock and being available seven days a week. Whatever the customer requirements, we committed to fulfilling them whatever it took.

One of the core repair services at the time was Orbital Honing which was the only method available to refurbish damaged crankshaft and tailshaft bearings. This process was slow and relied upon highly skilled technicians to achieve a good result. In those days hand filing (a very highly skilled craft) to correct ovality and misalignment was common practice.

It soon became apparent that a faster, more reliable and more accurate method was required to remove damaged material. Years of design and development resulted in the patenting of the worlds first orbital machining tool or "Orbitool" equipment. Simply described this was a single point tool mounted on a set of toolbars with a leadscrew to drive it along. This assembly sat in a metal cage and was driven around the shaft. The damaged material was "tooled" or "turned" off to reveal a perfectly round and concentric piece of undamaged shaft beneath. Then Orbital Honing was used as usual to provide a smooth surface finish.

These improvements and our commitment to working with the customer to get the job done, whatever the problems, led to the name Nicol & Andrew becoming an industry byword for quality in-situ marine repairs.

As other industry sectors became aware of our specialist services the demand increased for us to expand our range to include repairs specific to their industries.

Nicol & Andrew is firmly established as a world leader in in-situ repair technology and on site repair services.

In every industry sector we provide equipment tailored to the repair environments and customers specifications. Whether the repair is in a ships engine room at sea or in the classified area of a Nuclear Power Station, we have trained personnel and specialist equipment to meet our customers needs.

We now provide a total package of on site services to give our customers Turnkey solutions to their maintenance and breakdown problems.

We work with our customers to help reduce downtime, increase productivity and lower operating costs.

We have established a broad range of on site services designed to restore equipment to its original (or better) condition. These now include additive processes (where we apply materials or coatings) such as welding, metal spraying, electroplating and metal stitching.

We replace lost metals and even apply high performance wear resistant or protective layers. This type of repair can return your equipment to it's original size with the benefit of utilising standard rather than undersize bearings Saving Time and Money.

Nicol & Andrew are dedicated to maintaining and building on the high quality of service provided to all our customers. With over 46 years in the emergency repairs business we have identified the areas within our company which are critical to quality performance.

  • Personnel:- Nothing is ever achieved without good people. We are very careful who we choose and we use "in house" and "on the job" training (over a number of years) until they can prove their capability. We deliberately look for skilled engineers with the result that now over 90% of our technicians have served full engineering apprenticeships.

  • Teamwork:- Working on your own is sometimes necessary "on site", but no one here loses sight of the fact that each contract completed requires a team effort. At Nicol & Andrew we have always considered the customer an essential part of the team. Our customers have come to expect involvement at every stage of the contract. This enables them to plan ahead and minimise production downtime.

  • Equipment:- We constantly re-design, update and invent new ways of providing a better service to our customers. Using the latest CAD/CAM techniques our new range of orbital equipment for example is now ten times faster at removing metal, it's accuracy and repeatability is much improved and it is more versatile.

  • Information:- Information is king. We are always looking at ways to speed up the flow of information. In this business the smallest error in the information (gathered or broadcast) can lead to costly delays, or worse. We ensure all our information is checked for accuracy and we have computer databases networked to ensure all the up to date information is at everyones fingertips.

  • Quality System. Quality, like a marriage, has to be constantly worked at to get the best results. It has to be an inherent part of all the above areas but has a special place in the overall scheme of things. Our quality system is based on ISO9002, but it does not stop there. We have come to know what our customers want and we continually change our system in order to better serve their needs. Our past performance record and our long term customers serve as proof of the effectiveness of our quality system. We are of course approved by the major classification bodies such as Lloyds, Bureau Veritas etc., also the MOD, National Power, Nuclear Electric, Esso, Mobil, Shell, Alstom, ABB, Wartsila, B&W to name but a few.

Finally, when we carry out a repair these days we know it is right and we prove it by first setting up, and then checking, using the latest calibrated measurement equipment including optical and laser alignment methods. The finished repair is guaranteed within OEMs, (Original Equipment Manufacturers), tolerances and specifications.

We also carry an extensive array of specialised Non Destructive Testing (NDT) equipment to ensure integrity of the finished repairs.
