While environmental protection was a key factor in the decision to move away from oil-lubricated shaft systems, Lomar’s Technical Department remarked that the long-term savings expected on operational expenditure are “very attractive”. While more expensive in terms of CAPEX, Lomar calculated a lower total cost of ownership from the long term savings offered by seawater lubrication, making it a very cost-efficient alternative to stern tube oil-based systems.
Lomar sees a long-term trend across the shipping industry to implement solutions capable of reducing the impact of operations on the environment and seizes every opportunity to do the right thing for the environment. The introduction of these latest, high specification, fuel-efficient vessels is following this commitment.
The COMPAC system meets the most stringent environmental demands with seawater replacing oil as the lubricating medium. Designed by China’s MARIC and built to DNV GL class, the Super ECO 2700 vessels, are the first to operate according to the classification society’s stringent TMON requirement. This means they benefit from the same extended shaft withdrawal inspection periods as an oil-based system if certain monitoring conditions are met. With a hull form designed for maximum fuel-efficiency, DNV GL’s RCP notation optimises reefer container carriage in a way that further reduces energy consumption.
“This order is a significant breakthrough for seawater-lubricated stern tube systems not only in the shipping industry but the containership segment as a whole,”said Alexandros Alexandropoulos, Project Director, Technava, Thordon Bearings’ Greece-based distributor that worked with Lomar on the seawater-based solution.
“Lomar has a clearly defined set of social responsibility standards that must meet the highest level of compliance, so we are delighted that Thordon is considered a trusted manufacturer of environmentally safe solutions. Lomar selected COMPAC because of the brand’s reputation, design reliability, zero impact on the marine environment and extended warranty.”
