Cylinder lubrication systems specialist HJ Lubricators has launched SIP+, a next-generation upgrade of its patented Swirl Injection Principle (SIP) valve for two-stroke marine engines – providing a big benefit for shipowners seeking to cut fuel-oil consumption and minimise retrofit downtime.
Shipowners seeking to reduce fuel-oil consumption and minimise retrofit downtime have a new solution in SIP+, the latest evolution of HJ Lubricators’ patented Swirl Injection Principle (SIP) valve for two-stroke marine engines.
The redesigned, dual-fuel-ready SIP+ valve eliminates the need for internal liner machining and top-cover removal – a breakthrough that reduces installation time by more than one-third. This enables retrofits to be completed during normal port stays, cutting downtime and associated costs.
SIP+ retains all the advantages of the original SIP design: uniform oil-film distribution, reduced liner wear, and lower lube-oil consumption. It is fully compatible with existing lubrication systems and optimised for modern operating conditions, including thin-oil and dual-fuel engines.
Lower lube-oil consumption translates directly into reduced OPEX, while less oil burned means lower CO₂ and particle emissions – helping owners meet increasingly strict emission standards. HJ Lubricators estimates a typical payback period of around three years and offers an online calculator for precise savings estimates.
