Mooring Tails Explained: Materials, Length, MBL & When They’re Required Mooring / Commercial marine / Technical guide A mooring tail is the short, elastic length spliced between a stiff mooring line and the ship — and on most tankers it isn’t optional. Here’s what it does, how it’s sized, and when OCIMF rules make it a requirement rather than a choice. Technical figures in this guide are drawn from OCIMF’s Mooring Equipment Guidelines (MEG4) and published manufacturer technical guidance — see references below.

Commercial Marine / Towing / Technical Guide Towing Pennants in Tug Operations: The Sacrificial Link That Protects Your Mainline On a working tug, the pennant is one of the least expensive components in the towing assembly — yet it has a major influence on mainline life, connection speed and the reliability of the towing system under load. This guide is written for tug masters, marine superintendents and harbour towage operators: what the pennant is there to do, how the two strength philosophies differ between ship assist and ocean towing, and what two recent UK tug incidents taught the whole industry about inspection and retirement.

HMPE & Dyneema Rope Applications: Where High-Strength Fibre Earns Its Keep

HMPE & Dyneema Rope Applications: Where High-Strength Fibre Earns Its Keep Technical guide/HMPE & Dyneema/Rope applications HMPE rope — high modulus polyethylene, best known by brand names such as Dyneema® and Spectra® — has moved from specialist niche to default specification across a growing list of demanding jobs. Weight for weight it can be up to fifteen times stronger than steel, it floats, and it carries almost none of the recoil energy that makes a parting steel line so dangerous.

How to Splice Rope: A Step-by-Step Guide for 3-Strand and Braided Rope Technical guide/Splicing/Rope termination A splice is the strongest and neatest way to put a permanent eye, join or finished end into a rope.

That is why riggers, vessel crews and rope access technicians splice rather than tie whenever a termination has to be relied upon.
