PILE LOAD MEASUREMENT - Determination of pile capacity, driving resistance, 

 or lateral load. 



PILE PLACEMENT - Positioning piles for underwater driving or arranging 

 piles in a specified pattern. 



PILE PROTECTION - Prevention of damage to piles by ice, fouling, corro- 

 sion, or impact. 



PILE SECTION CONNECTION - A means of splicing lengths of pile or joining 

 adjacent sheet piling. 



PILE, CONCRETE - A long concrete column placed in the ground or seabed 

 as a support for an elevated deck or a foundation member, including 

 cast-in-place piles, when specified for marine use, or any type of 

 precast concrete pile or concrete-filled steel pipe pile. 



PILE, SHEET - A pile with a generally slender flat cross section to be 

 driven into the ground or seabed and meshed or interlocked with like 

 members to form a diaphragm wall, cofferdam, or bulkhead. Pile 

 material is signified by PILE, CONCRETE; PILE, STEEL; or PILE, WOOD. 



PILE, STEEL - A long steel column placed in the ground or seabed as a 

 support for an elevated deck, a foundation member, or a part of a 

 protective barrier, including thin shell piles when specified for 

 marine use, or any type of H or steel pipe piles. 



PILE, STRUCTURE CONNECTION - A means of joining a pile to the structure 

 it supports, for example, a pier deck or offshore platform jacket. 



PILE, WOOD - A long timber column placed in the ground or seabed as a 

 support for an elevated deck or a foundation member. 



POLLUTANT ABSORPTION - Removal of liquid pollutants from the water's 

 surface by absorbing them into a porous material or by adsorbing 

 them onto a surface, the material or surface being in the form of 

 particles, belts, or mats. 



POLLUTANT BURNING - Control of combustion of floating liquid pollutants, 

 either to encourage removal by burning or to extinguish accidental 

 fires . 



POLLUTANT COALESCENCE - Chemical treatment of a floating liquid pollutant 

 to change its consistency, as a means to limit its spread, shrink the 

 area of its slick, or aid removal of it from the water's surface. 



POLLUTANT COLLECTION - Concentration of pollutants by mechanical means 

 before removal from a body of water, including the use of inverted 

 funnels to collect leakage from the seabed, of towed surface barriers 

 to collect slicks, and of various forms of weirs or sluice gates to 

 concentrate floating pollutants in collection barges.
