A message from gCaptain sponsor, Castrol Marine
”We have responded to increasing demand from our customers for wider availability of our Cyltech 80 AW cylinder oil by expanding the supply network from five to 35 ports in key regions,” says David Goosey, Castrol Marine’s Chief Executive and Sales Director. “The popularity of our premium 80 BN product has grown since being made available last year via our main regional distribution hubs.”
Ports where customers will be able to book supplies will now take in major trading centres, including Antwerp, Rotterdam, Le Havre, Marseille, Hamburg, Bremen, Kiel, Singapore, Port Klang, Busan, Ulsan, Los Angeles, San Diego, San Francisco, Fujairah, Dubai, Jebel Ali and Khor Fakkan.
Castrol’s recommendation that owners adopt Cyltech 80 AW was initially prompted to address the implementation of slow steaming practices by operators of large containerships fitted with large bore 2-stroke crosshead main engines. However, wider availability reflects a direct response to increasing demand for other mainstream vessel types, including bulk carriers, for an OEM-approved product proven in diverse service.
Cyltech 80 AW is formulated for lubricating the cylinders of all types of crosshead engines operating on high sulphur residual fuel, typically above 2.5%. It is also especially recommended for ships operating under slow and super slow steaming conditions when main engines operate at reduced power, often below 60% of their full load capability.
Under such conditions cylinder liner temperatures are reduced and oil residence time is substantially increased. Both factors intensify demands on the cylinder lubricant to neutralise the acids formed as a result of combustion.
Another concern when slow steaming is that considerably less lubricant is fed into the engine and, under severe conditions, the prevailing lubrication regime moves from hydrodynamic to more boundary conditions; this may result in oil film breakdown and risk of mechanical wear.
Cyltech 80 AW can prevent reduced periods between unit overhauls that can occur with lower BN products by offering:
Low oil feed rates can be maintained even when slow steaming, helping to control annual lubrication costs.
“We know from field experience that Cyltech 80 AW provides improved neutralisation capacity and hence better corrosion protection across the fuel sulphur range while slow steaming than a mid-BN lubricant,” says Paul Harrold, Castrol’s Marine and Energy Technology Manager.
“By selecting the right cylinder oil for the right operating conditions, customers reducing their fuel bill by slow steaming, can be confident in the knowledge they are not risking damage to their engine; and that is why we recommend Cyltech 80 AW for many customers.”
