Last I checked, Chevron doesn't have any sailboats in their fleet as a general rule. There is a significant difference in the practices of tying up a commercial freighter or oil tanker, from those used by non-commercial, significantly smaller sailboat owners. I wouldn't want any vessel massing over 100 tons to get any movement or inertia...
Also, the cleats on a large steel ship have significantly more strength than do the ones on most smaller sailboats, which are held largely in place by the strength of the laminate in which they are fastened. Shock loading large steel cleats that are welded in place is probably less of a problem than doing so on a GRP sailboat. Boat wakes are probably not an issue for a 10,000+ ton steel commercial ship, but are a significant factor for small sailboats.
Polypropylene is a horrible material to use for docklines, as it is very weak, and extremely susceptible to UV damage.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
