5.3.1 Mooring

This subsection with figure only deals with mooring parts and naming-conventions. For the

appropriate mooring layout in your local conditions see section 5.8. Figure 5.3.2 depicts the

constituent parts of the mooring. The mooring starts with an anchor weight, preferably scrap

chain, followed by a polypropylene (PP) rope. The first few metres of PP rope keep clear of the

seabed by a small (3 Kg) inline float. The PP rope is connected to a rubber cord. For large

depths a sinker weight (sinker) is needed for the PP rope to keep clear of the sea surface. In

order for the sinking rubber cord to keep clear of the seabed in shallow water a 10 Kg float can

be attached at the lower end of the rubber cord. Rubber cords for 0.9 m and 0.7 m buoys have a

diameter of 35 mm and 27 mm, respectively. The total length of rubber cord amounts to 15 m

for the non-directional WR-SG, and 30 m for the directional buoys, DWR-G and DWR MkIII.

The rubber cord either comes in one piece of 15 or 30 m, but can be supplied in any length in

order to mount extra floats in shallow water. Directly underneath the buoy a stabilizing chain is

attached. In the case of the WR-SG and DWR-MkIII a swivel is incorporated in the lower end

of the chain. All metal parts are made from AISI 316 stainless steel avoiding galvanic corrosion,

except for any sinkers and the shackle connecting the PP-rope to the scrap chain.
