Here at Tufcot, we are very proud that our Tufcot® T100 Marine material has achieved two very important approvals:

  1. Lloyd’s Register Approval
  2. DNV Type Approval

Both are maritime classification societies, providing international standards for ships and offshore structures.

But what does this mean to achieve these approvals? And what are the benefits to our customers?

In this article, we’ll be taking a closer look at Lloyd’s Register and DNV as well as our own Tufcot® T100 Marine material and its uses in the marine sector.

Quality – Tufcot Sets Its Standards High

Lloyd’s Register

Founded in 1760, Lloyd’s Register is a “global professional services company specialising in engineering and technology for the maritime industry.”

They are the world’s first marine classification society, created to improve the safety of ships.

Our Tufcot® T100 Marine material has been entered on the Lloyd’s Register list of Approved Synthetic Rudder Bearings Materials.


DNV (Det Norse Veritas) was founded in 1864 and is now the world’s largest classification society.

Our Rudder Bearing Bushing Material, Tufcot® T100 Marine, is certified to comply with DNV’s standards as a “Type Approved Product”.

The material will soon be DNV approved for water lubricated stern tube applications too, with approvals from other societies to follow.

How Tufcot® T100 Marine Achieved These Approvals

Vessels are built according to a set of class rules.

Holding the approvals means that Tufcot® T100 Marine meets the standards set by each classification society and is permitted to be fitted on those vessels.

To gain the approvals, the material underwent a defined programme of mechanical and friction testing.

In addition, quality systems and manufacturing processes were audited to ensure that the material is manufactured in a consistent and traceable method.

Achieving these approvals means we can offer Tufcot® T100 Marine into the marine sector for new build vessels and for repairs where vessels might require replacement of rudder bearings and water lubricated shaft bearings at docking.

Benefits To Our Customers

For our customers, the Lloyd’s Register and DNV approvals mean they can approach new customers and markets where approval from a classification society is a pre-requisite for receiving enquiries.

Without approvals it can be difficult if not impossible to supply to these applications.

Other benefits include:

  • Confidence in the Tufcot® T100 Material

  • Rapid turnaround of marine grade approved tubes to help vessels during dockings

  • Material is manufactured to a high standard consistently
  • All orders are fully traceable
