Clements Engineering (known to its’ customers as Clements Marine) has been accepted as a corporate member of the National Workboat Association (UK).
The association was formed in 1994 so that its’ members could have a say in the formulation of the Maritime and Coastguard Agency Workboat Code of Practice. The Association has also played its part in the new Harmonised Code and has been successful in keeping its’ members interests at the forefront of any proposed regulatory changes.
Celebrating 30 years in business this year, Clements Engineering has supplied propellers, marine shafts, stern tubes and ancillary propulsion equipment to workboat builders and now is one of the UK’s leading manufacturers. Clements Engineering recently supplied to the latest workboat launch from Safehaven, the multi operational Orca III and the South Boat Projects crew transfer boat Chinook.
Clements Engineering’s work with all members of the teams on boat builds, from the project managers to the engine manufacturers, this enables their products can fit easily into build projects, and work most efficiently. All products are designed and tested to the highest standards in-house. Appointments such as official suppliers to the Russian Rivers Authority and the Royal National Lifeboat Institution (RNLI) testify the quality build of Clements Engineering products. They supply to vessels built under specialist service craft rules such as Lloyds Register of Shipping or Norske Veritas. Clements Engineering is accredited Germanscher Lloyd, ABS (ICE Class) and RINA approved manufacturers.
As well as new projects the team at Clements Engineering also provide propeller re-pitching, welding and repairs with short turn around times to enable their customer to have minimal downtime.
After completing many successful projects last year Clements Marine has worked on a major, landmark superyacht project with Ocean Yacht Systems (OYS). Having established a close relationship with OYS over many years this project was for a state of the art 66.7m yacht built at Baltic Yachts in Finland called Hetairos.
Using the Clements Marine propellers OYS produced 2 x 460hp hydraulic swing retractable primary drives for Hetairos, the first of their kind in the world. Combined they generate 14knts under power and provide a bollard pull in excess of 11000kgf. The units themselves rotate 360 degrees and are positioned either side of the centreline just aft of the keel, providing incredible manoeuvrability. Hetairos is built for performance, whether under sail or power, and therefore these hydraulic powered units fully retract into the hull within seconds when not in use, leaving a completely flawless hull.
For the project Clements Marine supplied a pair of thruster propellers 934mm x 1031mm manufactured from AB2. The propellers were a 4 bladed design to fit in a custom composite thrust nozzle to develop 460hp each.
The required bollard pull and required speed set out in the original specification was met and exceeded with the Clements Marine propellers.
A great deal of research and development work went into this project during the initial stages of the build. The technical team from OYS worked closely with Clements technical to achieve the perfect result.
The project is one that shows the true diversity of the Clements Marine product portfolio which is all designed and manufactured in their factory in Bedfordshire, UK.
OYS will be joining Clements Marine on their stand (B13) during the Seawork exhibition May 22-24 in Southampton.
2012 sees Clements Marine celebrate 30 years since it was founded.
Conceived as a general engineering company by John Clements in 1982, Clements Engineering originally manufactured parts for the Ford Cortina and also made the King Pin Lock, a neatly designed lock for articulated units.
The company moved to its current site in Bedfordshire in 1989 and Clements Engineering looked towards other areas of manufacture. An interest in boats and having seen an opportunity in the market place they increased the manufacture of marine parts, in particular, propellers, marine shafts and stern tube assemblies.
Over the years Clements reputation grew and as demand increased a key part of the quality process was to ensure all the functions were kept in house. The Clements own foundry completed the expansion in 2000 and this has proved a key benefit in controlling the manufacturing process.
Today the company employs nearly 40 people including its foundry and trains apprentices in its workshops in Bedfordshire. The design of products is achieved using modern CAE techniques and all products are tested to the highest standards required by the industry in house.
Last year saw Clements Engineering awarded certification to build their products to RINA, Germanischer Lloyd and ABS (Ice class) Standards. Appointments such as official suppliers to the Russian Rivers Authority and the Royal National Lifeboat Institution (RNLI) are a testament to the quality build of their products. The products are used throughout the world and exports remain steady despite the economic climate.
All propellers are scrutinised, tested and have attained the quality level of Class 1 as standard and Class S by request or as per the requirement of the authority. Clements Marine products are manufactured to exacting standards and matched prior to delivery at their factory to ensure trouble free installation and a long service life.
The team at Clements regularly advise customers on repairs, refits and re-pitching as well as the supply of new products. From attending sea trials to liaising with naval architects and engine commissioning engineers, along with developing new designs for specific requirements, the qualified team at Clements have a wealth of experience and product knowledge.

"The new pair of propellers supplied by Clements Marine have improved our pilot boat's performance. The top speed is increased, there is an improvement in the boats turning and handling - it seems like a new boat."
