Chain Size – Break Strength and Safe Working Load We’ve been reviewing our logic on chain size and thought a few points might be of interest. Material: HDPE Connecting Pin and Aluminum Frame DOCK BLOCKS. A calculation of the size of a mooring system must include a performance analysis under extreme conditions, for instance for an intact mooring system, with a break in one of the mooring lines and with an increase in the water level compared to normal due to a storm tide of 1 m for example (requirements in the Norwegian standard for cages). You should never anchor off your winch or use your winch to pull your boat to the anchor spot. If you are into yacht racing or rigging a new boat, it can be good to calculate the minimum required breaking load of sheets and halyards in order to reduce weight of ropes onboard. II - Offshore Structure Design And Construction - Paul A Frieze ©Encyclopedia of Life Support Systems (EOLSS) Additional piles, called skirt piles, can be inserted through and connected to sleeves at the base of the structure. Here, Captain Wash proposes a simplified system that may serve as a rule of thumb when looking at the mooring plan for a given location where local conditions are known.
