Chapter 8 DREDGER<br />
‣ Synthetic ropes are, when they break, extremely dangerous. Always treat them with extreme<br />
caution. Excessive wear of synthetic ropes is shown by a high degree of powdering between<br />
the str<strong>and</strong>s, giving a clear indication that the rope has been overtaxed <strong>and</strong> that its strength<br />
is impaired.<br />
‣ Ensure that :<br />
• Wires <strong>and</strong> ropes can move freely <strong>and</strong> cannot hook behind any obstacle;<br />
• When connecting two steel wires, both wires are either left or right h<strong>and</strong> laid;<br />
• Free ends of wires are whipped;<br />
• Wire rope clips attached with U-bolts have the U-bolts on the dead or short end of<br />
the wire; the clip nuts must be retightened at frequent intervals; U-bolts must never<br />
be used for lifting wires or slings.<br />
‣ Pay special attention to all kind of steel wires on board floating plant to ensure that there are<br />
free from the following defects:<br />
• Kinks;<br />
• Frayed str<strong>and</strong>s;<br />
• Knots;<br />
• Crushed parts;<br />
• Extreme rust;<br />
• Fractures;<br />
• Snags;<br />
• Damaged end connections.<br />
‣ Wires with the above-mentioned defects must be replaced <strong>and</strong> subsequently rendered<br />
useless.<br />
‣ Safety guards over wires have to be fitted where necessary <strong>and</strong> possible.<br />
‣ Ensure that wires <strong>and</strong> ropes are regularly inspected <strong>and</strong> that the inspection record/date is<br />
clearly visible on the equipment by using colour, label or date.<br />
‣ All new ropes, chains <strong>and</strong> slings purchased shall be accompanied with certificates.<br />
Access ways<br />
‣ Ensure that the under-mentioned access ways are free from obstacles , grease , oil <strong>and</strong><br />
mud:<br />
• Passage ways;<br />
• Walkways;<br />
• Workshops floors;<br />
• Platforms;<br />
• Staircases (ways);<br />
• Gangways;<br />
• Scaffolding.<br />
Soundings<br />
‣ The Captain/Senior Dredge Master must ensure that all compartments <strong>and</strong> buoyancy tanks,<br />
including fore- <strong>and</strong> after-peaks, are sounded daily/weekly, recorded in the logbook, <strong>and</strong><br />
passed on to the Chief Engineer, for recording in the engine logbook.<br />
Ballast Tanks<br />
