Description

Production Introduction

The ISO13795 double bitt towinging bollards are welded steel bollards, suitable for installation on sea-going vessels to meet normal mooring and towing requirements. The posts of the bollards shall be constructed from steel tubes or formed from plate. A low-friction surface coating is not recommended so as to increase the holding force of the mooring rope under figure-of-eight belay according to ISO standard.

Depending on the construction, the ISO13795 welded steel bollards shall be classified as two types, which are Type A - with compact base plate and Type B - with wide base plate.
