About Us


Marine Power Systems Ltd is a family owned business founded in 2013 to provide specialist diesel and propulsion technical services in New Zealand and the South Pacific. We have a vast experience with various types of vessels and machinery, always taking pride in providing professional and honest service.

The road has been a long one and our company is a culmination of many years of experience, learning and of course the odd mistake!


I have been involved with heavy diesel engines and propulsion systems my entire working life and you could say they have become a passion of mine. It all started when, as a young man, I signed up to an apprenticeship with the Royal Navy. At the time, the navy was going through a technical revolution and the old gas thirsty ships of old were steadily being replaced with modern (at the time!) diesel-electric propulsion plants. These ships were traditionally powered by Ruston, Mirrlees Blackstone and Paxman YJ and RPA series diesel engines and although they have now been long-since superseded, they were at the time, extremely powerful and compact engines. During the next few years I became to know these engines intimately inside and out, and performed many major maintenance intervals in-house such as top and bottom end overhauls.

It was around this time that I first encountered Condition Monitoring and in particular, Remote Visual Inspection (RVI) techniques. RVI uses small diameter borescopes and flexible videoscopes to inspect internal components and systems which would other wise be impossible to inspect without major engine tear-down. The advantages of these techniques was immediately apparent, saving time, money and ultimately reducing vessel down-time. RVI is not limited to diesel engines as it was just as useful for inspecting gas turbine blades, boiler tubes and the inside of pressure vessels to name just a few.

Time has since moved on and the YJ’s and RPA’s have been mostly been replaced with modern diesel engines from manufacturers such as MAN, Wartsila, Caterpillar and MTU. However these engines are still subject to wear, damage and unfortunately, sometimes neglect. The techniques of performance monitoring and routine inspection coupled with good technical knowledge has always been the most effective form of condition based maintenance I have experienced, ultimately increasing engine reliability and lowering costs.

There appeared to be a lack of specialist marine propulsion knowledge in New Zealand and on too many occasions I observed poor workmanship and inaccurate diagnosis carried out by various organisations. Unfortunately the persons involved were often wearing a reputable uniform and this led most people to believe they were receiving a good service.

This experience proved to be the foundations for our company and in 2013, we started to offer quality technical inspection, diagnostics and repair services for many of the large fleet operators in New Zealand. As strong advocates of condition monitoring we believed that with the right blend of performance monitoring, non-intrusive inspection and intelligent maintenance scheduling, huge benefits to performance and reliability can be realised. Our customers have since experienced this for themselves.

In 2014 we began work on one of the largest superyachts ever built, providing specialist commissioning services for the complex propulsion plant. This was immediately followed by contracts for further superyacht projects both in New Zealand and overseas. Our services were also utilized by many commercial operators such as the fishing fleet and Auckland ferries, most of whom remain loyal customers to this day.

Throughout the years we have added many new services to our offerings to complement our core diesel work. These include laser shaft alignment advanced diagnostics CPP propulsion system repairs/overhaul and pre-purchase surveys.

In 2016 we added new products to our offerings designed to monitor the performance and efficiency of propulsion systems. These instruments have proved extremely valuable, alerting our customers to defects long before failures occur. We now offer monitoring services to analyse the data from these instruments on a weekly or monthly basis, providing customers with the data and recommendations to make informed decisions.

We often work alongside ships crews and employees and are more than happy to assist with training and pass on our knowledge to your team.

So that’s a brief introduction to our company and where we come from. Please feel free to contact us with any questions you may have. We hope to meet you soon.
