Open channel applications include bank stabilization, flow and grade control, scour protection for bridge piers, and biostabilization. The primary mechanism of protection employed is an increase in the relative roughness of the channel bank (as characterized by the Manning's Roughness Coefficient ); the Manning's n is relatively high at 0.1.
The boat may be either floated on and off the trailer or pulled off. When recovering the boat from the water, it is winched back up the trailer. From 1925 onwards, modern whaling factory ships have usually been equipped by their designers with a slipway at the stern [2] to haul harpooned whales on deck to be processed by flensers. [3] [4] [5]
Cathodic protection (CP; / k æ ˈ θ ɒ d ɪ k / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. [1] A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes ...
There are several types of bridge protection systems used: [7] Pile-supported fender system on the James P. Houlihan Memorial Bridge. Fender systems attached to the pier with the goal to absorb the vessel impact. Their ability to withstand a typical ship collision is low. Fenders are built using a variety of materials: [8] thin-walled concrete box;

Grouted tiebacks can be constructed as steel rods drilled through a concrete wall out into the soil or bedrock on the other side. Grout is then pumped under pressure into the tieback anchor holes to increase soil resistance and thereby prevent tiebacks from pulling out, reducing the risk for wall destabilization.

However, if the lifeboats are "easily transferable" (i.e. have an open deck between port and starboard lifeboat decks), the number of liferafts may be reduced to a total sufficient for the ship's capacity. [clarification needed] The equipment carried in a liferaft is much less than a lifeboat.
