Standard Practice for Installation Procedures for Fitting Chocks to Marine Machinery Foundations
SIGNIFICANCE AND USE
3.1 This practice provides the three principal methods of fitting chocks to marine machinery foundations to ensure that the machinery is free of vibration and perfectly aligned after installation.
3.1.1 The three principal methods of installing chocks described herein are as follows:
3.1.1.1 Type A—Epoxy-based resin, nonshrinking, and
3.1.1.2 Type B—Two-piece wedge chocks.
3.1.1.3 Type C—Solid, one-piece fitted chocks.
SCOPE
1.1 This practice covers the acceptable methods of fitting chocks to marine machinery foundations.
1.2 The values stated in SI units shall be regarded as standard. The values in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Significance and Use
3.1 This practice provides the three principal methods of fitting chocks to marine machinery foundations to ensure that the
machinery is free of vibration and perfectly aligned after installation.
3.1.1 The three principal methods of installing chocks described herein are as follows:
3.1.1.1 Type A—Epoxy-based resin, nonshrinking Chockfast Orange PR 610 TCF by Philadelphia Resin Corp., or equal,
nonshrinking, and
3.1.1.2 Type B—Two-piece wedge chocks.
3.1.1.3 Type C—Solid, one-piece fitted chocks.
4. Procedure
4.1 General Requirements for Types A, B, and C Chocking Systems:
4.1.1 Machining:
4.1.1.1 Type A chocks, machinery bedplates, foundation plates, and bolts do not require finish machining if the chocks are not
designed to be removed. Unless specified otherwise, Types B and C chock, bolts/studs, machinery bedplate, foundation plates, and
fitted holes need to be finished machined and fitted.
4.1.1.2 Surfaces in way of the chock areas on the machinery bedplate and the foundation plate may be machined before installation
or while the ship is not waterborne, or both.
4.1.1.3 Unless otherwise specified, all finished surfaces shall be finished to a maximum of 0.003–mm roughness height average
(RHA).
4.1.1.4 Finished areas on the machinery bedplate and the foundation plate in way of the chocks shall be sufficiently greater in size
than the chock to prevent interference from the unfinished area with the chock during installation.
4.1.1.5 Spotface hole edge radius shall be such that there will not be any interference between it and the bolt head-to-shank radius.
The spotface area shall be sufficiently greater in area than that of the bolt head or nut so as no
