Offshore Hydraulic Cylinders / Rams

Market leading innovations with offshore hydraulic rams / cylinders

Our Experience with Offshore Hydraulic Cylinders

With over 30 years’ experience repairing cylinders across a diverse range of industry sectors; we have developed an unrivalled understanding of the design limitations of cylinders from a wide variety of manufacturers.

Our ability to develop solutions for different environments has ensured we can offer the best possible manufacturing solution across many industries.

This understanding has enabled us as to become a key player within the marine cylinder manufacturing arena.  Our ability to develop solutions for different environments has ensured we can offer the best possible manufacturing solution across many industries.

Certification Available with Each Task Completed

Full ‘test and certificates of conformity’ are available should you need them.
We can also manufacture hydraulic cylinders with third party approval certificates such as:
  • DNV GL (Det Norske Veritas) DNVGL-CG-0194 (formerly standard for certification No.2.9)
  • ABS (American Bureau of Shipping)
  • Lloyds Register
  • ISO 9001:2015

Rod / Piston Corrosion

Rod and piston corrosion is one of the major causes of cylinder failure within the offshore marine oil industry. This problem not only causes cylinder failure, but can also cause system contamination which leads to costly failure of other components.

Our extensive selection of piston coating solutions is achieving excellent field results in prolonging piston life and the prevention of corrosion

Following collaboration with OEMs and end users, we have developed a new range of piston coating solutions which significantly improve cylinder durability.

Our extensive selection of piston coating solutions is achieving excellent field results in prolonging piston life and the prevention of corrosion. Our tailor made solutions are matched exactly to the cylinder’s environment and application and are worked around each individual customer’s budget.

Our commitment to excellence and client satisfaction means every cylinder produced at Apex is  rigorously tested according to our customer’s requirements. If you would like more information on our testing procedures or would like to witness them first-hand please contact us. You are invited  to come along, either with a verification body or simply to see our technical team in action.

Frequently Asked Questions…

Can you manufacture a cylinder to our third party inspections agency specifications?

Yes, we manufacture to all specifications, including DNV-GL, Lloyds Register, ABS and BV. We are happy to supply certificates of conformity if you require them.

Are you willing to have regular inspections by our third party inspection agency?

Yes, this is common and we often work with these companies on a monthly basis. We are happy to allow them access to our facilities and keep them updated on every aspect of your cylinder design and manufacture. We have our own inspection department, and are willing to test to whatever specifications are required, as well as allowing inspection agencies access to the cylinders to complete their own tests.

What is your turnaround time?

We understand that in some cases, new hydraulics are needed as a matter of urgency and that down time is costly and problematic. Depending on complexity, cylinders are generally manufactured in a 4-8 week lead time, though we have been known to manufacture new cylinder designs in a matter of days.

Do you have a branch in our country?

We are based in England, but we export to almost any country. We’re able and willing to work with you from here in the UK and we work all over the world; and often the other side of the world! We communicate regularly via e-mails and conference calls. We have worked on projects as far away as Australia, and have not found the 12 hour time difference to be a problem.

Our project is huge - what’s your capacity?

We have a well equipped workshop in Dewsbury and are yet to find a cylinder we can’t manufacture. All sizes, models and specifications can be happily catered for by Apex.

We currently have a working cylinder - can you make one to the same specifications?

We can make cylinders to any specifications you require. If you already have the specifications we are happy to manufacture it while the working model is in use. Without the specifications we will need to examine the current model and can engineer a replica from that. We are usually able to make a new model with the same specifications but an even better design.

What is more cost efficient for our faulty hydraulic cylinder - repair or replacement?

While we are able to repair all hydraulic cylinder breakdowns, there may be occasions where replacement is more cost effective. Our strip and assessment department is able to quickly assess the damage and ascertain what a repair will involve, in order to be able to give you an accurate quote for repairs for you to base your decision on. Call us for more information.

Can you repair our cylinder that is no longer working?

Yes, we have yet to find a cylinder that we cannot repair! We are able to repair all aspects and all types of hydraulic rams. Please call to speak to one of our technical team to get further details. See details on our hydraulic ram repair HERE.

We have a cylinder that currently keeps breaking down - Can you replace it with one that lasts longer?

Yes! We have yet to find a cylinder that we cannot manufacture or repair. At APEX we have over 30 years of experience with hydraulic cylinders and we understand what works, and what doesn’t. We have a wealth of experience in the off shore industry and understand the stress and strains that a hydraulic ram is under within this industry. Therefore, in almost all cases we are able to design a cylinder to fit in the current fabrication, that can last longer that the original manufacturer hydraulics. We also have specialist piston coating solutions that are perfectly suited to the harsh environments of the offshore industry, and that can improve the durability of the hydraulics substantially.

Component Selection

  • Apex’s strong supplier network means we can guarantee the final product is of the highest quality
  • All parts are traceable from manufacturer to supplier and supplier to product
  • All raw materials used in manufacture come complete with certification compliant to EN 10204 TYPE 3.1 or 3.2

Apex’s strong supplier network means we can guarantee the final product is of the highest quality

Cylinder Testing

Every cylinder we manufacture or repair is rigorously tested by our experienced hydraulics engineering team.

We are able to test on any fluid and provide you with a certificate of oil cleanliness with every cylinder test certificate.

We are so confident that you will be impressed with our engineering expertise we invite you or any third party to witness our testing program first hand!

Minimising down time

We understand how vitally important it is within the offshore industry to minimise downtown in order to keep tighter control of costs.

We therefore work with you to ensure your new or repaired cylinders are delivered and working within your specific deadline.

…Whatever it takes, we will pull out all the stops.

We are now in Aberdeen also, call us on 01224 466297
