Oil Savings Calculator – a Tool from Thordon Bearings



Thordon Bearings has launched a Oil Savings Calculator to know the amount of oil prevented from leaking into the world’s oceans with each installation of a seawater lubricated propeller shaft bearing.

The product will be launched officially on 26th April 2016, to coincide with Earth Day, 2016, the world’s largest environmental movement, now in its 46th year, the Oil Savings Calculator shows that more than 60 million litres of oil pollution have been saved to date.

“In our opinion the only acceptable propeller shaft stern tube oil leakage is zero,” said Terry McGowan, President & CEO Thordon Bearings.  “Thanks to those vessels that have already installed seawater lubricated propeller shaft bearings, over 60 million litres (almost 16 million U.S gallons) of stern tube oil has been saved from entering our oceans, seas, lakes and rivers.  The Oil Saving Calculator is updated constantly and will continue to track our contribution to removing stern tube oil from our waters with the greater goal of completely eliminating this source of pollution.”

Supporting the initiative, Dr Karen Purnell, the Managing Director of the International Tanker Pollution Federation (ITOPF) said: “As the world’s largest shipowner organisation, ITOPF supports measures designed to help our members and associates meet high environmental standards.  Though our primary function is to promote an effective response to marine spills of oil and chemicals worldwide, we also support the maritime industry in its efforts to reduce ship-sourced pollution and provide for more sustainable marine operations.”

How is it calculated:

It is based on detailed statistical analysis of the number of vessels that have been built with or converted to seawater lubrication, the 300 days a year each vessel is typically operational and an average oil leak of 6 litres (1.6 U.S gallons) per day per vessel.

Independent research carried out by New York-based Environmental Research Consulting indicated in 2014:

  • The total amount of operational oil discharges from ocean-going vessels could be more than 240 million litres annually.
  • To add perspective, the oil pollution from the Exxon Valdez casualty of 1989 was 41.6 million litres.

Shipowners can monitor the positive impact the seawater lubricated propeller shaft bearing is having on the marine environment by checking the Oil Saving Calculator counter at www.thordonbearings.com.

“The counter provides a good indication as to what we as a company and the shipping industry, in general, can achieve if we continue to work together to develop eco-friendly solutions,” said Craig Carter, Thordon Bearings’ Head of Marketing and Customer Service.
