TUG FENDERS INTRODUCT

Tug fenders must work under more extreme conditions than any other fender type. Tugs may be fitted with many types of fendereach type serving a particular application.

When selecting fenders, designers should consider contact loads, Pushing angles, friction and etc.

A. Cylindrical fenders:Fitted to the bow/stern of tugs and usually used topush against flared hulls andin open sea conditions.

B. Pushing fenders:Keyhole, Square and W-and M-fenders provide large contact surfaces for low hull pressures. Their grooved surfaces provide exceptional grip.

C. Side beltings:D, Square and Composite fenders are often used as side beltings to protect the vessel during escort duties and when coming alongside.

D. Stern of tugs:Usually use Cylindricalfenders or any other types.

[Units: mm, kg/m]

Attachment:Smaller fenders (<500mm diameter) are usually fixed by a longitudinal chain through the bore of the fender, connected to the hull by turnbuckles to tension the chain. Larger fenders often use supplementary chains or straps around the fender.
