Harbour and Escort TowingThe role of the tug’s towline issometimes underestimated yet it isthe vital element that provides theconnection in any tow. Bridon havebuilt a world class reputation in thisindustry and have developed anunrivalled portfolio of towing productsto meet the exacting demands oftoday’s world-wide tug boat operator.

No two towing operations are thesame, which is why rope selection iscritical. Bridon’s experience ensuresthat you can select the optimum ropesolution for your particular operation.

Bridon utilise their extensive laboratoryfacilities for testing and analysis of usedtowlines. Working closely with towingoperators Bridon provide engineeredsolutions for today’s requirements andtomorrow’s challenges.

SteeliteApplication Drivers:High strength, light weight

Steelite is the ideal choice wheretoday’s environment demands asubstantial increase in bollard pull.Steelite products are available in 12 strand roundline or in Superlineconstruction.

Steelite ropes exhibit the highstrengths associated with steel yet are very low weight, allowing them tofloat in water. This low weight makesSteelite easy to handle for both thetug and ship’s crew and enables aquick connection to the towed vessel. It has excellent fatigue life andis very durable. Steelite ropes havelow extension and consequently alower lash back energy than othersynthetic ropes so ensuring a saferworking environment.

Today’s towing operations aregenerally via a winch. As a wirereplacement Steelite is very easy touse, in that it’s laying on the drum isnot as critical as steel wire and unlikewire Steelite does not damageancillary equipment so saving onmaintenance costs.

As a synthetic upgrade to wire, Steeliteallows for far greater storage on thewinch. A low friction factor enables therope to slide through leads withminimum resistance and wear.

Superline Steelite’s protective coveroffers complete protection to the loadbearing cores. If wear and tear doesoccur, a fault can be quickly identifiedand easily repaired with simple overseizing. A number of specialist extraprotective covers are also available.

All Steelite products are available in standard and higher strength Xtra grades.

Superline PolyesterApplication Drivers:Hardwearing – Proven trackrecord

Superline Polyester is used inapplications where larger ropes canbe effectively handled and a higherelasticity is required. Increasedelasticity can help to reduce shockloads in dynamic situations yet stilloffer complete control in a towingenvironment. The core/coverconstruction gives Superline Polyesteran excellent fatigue life.

Ocean TowingSeveral other products are also usedfor specialised towing applications.Nylon Braided springs are often usedin ocean towing for their highelasticity. Steelite towline’s can alsoreplace the wire catenary.

Steelite is the ideal synthetic substitute for steel wire. Size for size it displaysthe same strength as wire and has the advantage of floating in water. Steeliteexhibits lower lash back energy than other synthetic fibres and unlike wire willnot unravel dangerously. Mooring times can be cut resulting in quickerturnaround periods in port and vessels can be moored securely with only asmall number of personnel. The lightweight properties of Steelite makehandling easy and reduce the risk of personal injury.

Existing steel wire winches can be used with minor modifications to store theequivalent length of Steelite ropes and savings in maintenance costs onancillary equipment can be made.

Polyester ropes display excellent fatigue life compared to other syntheticmaterials and steel wire. The latest generation of HydroShieldTM marine finish canbe utilised to further reduce internal abrasion and increase service life.

In towing applications where larger ropes can be handled, Polyester’s dynamiccharacteristics can help reduce shock loads whilst maintaining control over thetow. The elongation characteristics of polyester fall between Steelite and Nylonmaking it ideal for applications involving moderate dynamic loading.
