CHAPTER 11
HEAVY WEATHER MOORING GUIDELINES
11-1
INTRODUCTION. The purpose of this guidance is to advise facility
engineers, planners, and maintenance personnel of minimum facility planning and design
criteria necessary to ensure safe mooring of naval vessels during Mooring Service Type
III (Heavy Weather). Use this UFC to validate existing sites for heavy weather use and to
design new or modified facilities and moorings for heavy weather. Existing facilities and
moorings should not be used for heavy weather if they do not meet all criteria noted
herein unless provisions are made according to COMNAVSEASYSCOM msg R 130351Z
Jul 95 YZB . Since no Building Code or non-government standard exists for Mooring
Service Type III design, this UFC provides the relevant safety requirements and criteria
for facility aspects of ship mooring.

Heavy Weather mooring studies for COMNAVSURFLANT by COMNAVFACENGCOM,
NFESC, and COMNAVSEASYSCOM. This criteria has been extensively coordinated
with COMNAVSEASYSCOM and internally within NAVFACENGCOM,
COMNAVSURFLANT, CINCLANTFLT N37, N46, and CINCPACFLT N37, N46. It
includes state of the art technology in vital facility areas such as mooring and risk
assessment. Congressional support for all new construction is dependent on specific
planning and design criteria applied consistently throughout the Navy - hence, the need
to formalize this criteria. Upgrades to existing facilities likewise require documentation
of new "code" requirements. A great deal or work has been performed to ensure that
ships are safely moored in Heavy Weather conditions. For example, below is a list of
some of the NFESC reports on Heavy Weather mooring.
