A HISTORY OF EXCELLENCE ROCOL® has been providing engineers with high performance lubrication solutions for more than 130 years. During that time some of the world’s leading companies, operating in the harshest of conditions, have benefited from the knowledge and expertise of ROCOL. THE IMPORTANCE OF CABLE LUBRICATION The physical demands placed on umbilicals and wire ropes are often underestimated. Cables are required to safely manoeuvre valuable loads weighing of up to many thousands of Kilograms whilst: • Resisting the most corrosive of environments • Shielding against abrasion • Being flexible...

It has never been more important to choose the most environmentally acceptable lubricants. Over 10% of oil input into marine waters is estimated to originate from lubricants(1). Additionally, worldwide clean up and damage costs are estimated to be greater than £200m(2). The integrity of the marine environment must be protected by careful management of actions at sea and on the coast. International standards such as ISO 14001 and ISO 14031 encourage organisations to utilise "performance indicators" in an effort to protect the delicate marine environment. When choosing the correct lubricant to...

INDEPENDENTLY TESTED PERFORMANCE BIODEGRADABILITY Test: Result: Readily Biodegradable (70%) Biodegradability is a measure of how quickly a substance is broken down into harmless constituents. The concentration of WIRESHIELDTM Biogen ROV in sea water was tested after 28 days and awarded the top classification of biodegradability. ECO-TOXICITY Test: Readily Biodegradable 70% WIRESHIELD Biogen ROV Inherently Biodegradable Acartia Tonsa WIRESHIELD Biogen ROV was designed and tested to demonstrate that its impact on marine life is minimised.

PSEUDOPLASTIC RHEOLOGY Shear or agitation causes a reduction in the dynamic viscosity of WIRESHIELD Biogen ROV: • Allowing maximum penetration into umbilicals and wire ropes. • Increasing pumpability during application, minimising blockages. TM While at rest the lubricant behaves like a grease: • Optimising wash-off and fling-off resistance. WIRESHIELD viscosity is initially similar to that of grease. Shear induces the “collapse” of the thickener system. Viscosity quickly approaches that of an oil. Shear Rate Standard Grease CORROSION RESISTANCE Test: Result: Zero galvanic reaction after 1000...

BIOGEN ROV APPLICATION Methods of cable lubrication range from traditional techniques such as brushing and swabbing to the use of performance equipment. WIRESHIELD Biogen ROV can be applied using whichever method is most convenient, but in order to maximise efficiency, ROCOL recommends CoreLube or other automatic delivery systems. The use of WIRESHIELD Biogen ROV with an automatic delivery system: • Forces lubricant into the wires and strands of the cable • Prevents build up of excess lubricant • Offers cost savings due to increased lubrication speed • Is suitable for use on a range of umbilical...
