Hans Jensen Lubricators

Hans Jensen Lubricators (HJL) is the leading global provider of cylinder lubrication systems for two-stroke marine engines. After more than 100 years in operation, we have retrofitted more than 3,500 vessels worldwide.

Hans Jensen Lubricators was founded in 1917 in Copenhagen, Denmark by engineer Hans Peter Jensen. After sailing for 7 years at sea with DFDS, Hans Peter went ashore and started a 25 sqm. blacksmith shop. He was contacted by Danish shipyard B&W, who were looking for a partner to produce lubricators for large, diesel-powered ocean liners.

This created the need for a factory to help the company make lubricators on a larger scale, and as operations continued to expand, the company moved to Hadsund, Denmark, where it is based today.

HJL’s first SIP valve was born in the 90s – a product of real innovation from the company’s expert engineers. The ‘Swirl Injection Principle’ is a patented method for optimized lubrication of the cylinder liner by atomizing the spray of lube oil into the combustion chamber. More lubricator models soon joined the product range, with the HJ Smartlube becoming the icon of the HJ-series.

In 2014, the Singapore office opened under the management of the fourth generation of the Jensen-family, who are in charge of daily operations today.

In 2022, HJL became part of the Danish G&O Maritime Group, which is a cluster of maritime companies covering various needs aboard vessels. The collective mission is to make vessels a greener and safer place to work.
