Section 4: General Lay-Up Mooring Practices A. The standard permanent mooring arrangement for the FREEDOM STAR is designed to withstand all weather conditions up to and including storm force winds up to 63 KTS (73 MPH).

B. It will be standard practice for the FREEDOM STAR to remain moored at her designated lay-up berth located at Lundeberg School of Seamanship, Piney Point, MD during heavy weather events. This berth is oriented East / West (000/000 MAG).

C. Standard practice is to moor the FREEDOM STAR starboard side to the pier heading South Southwest against polyethylene pilings in accordance with the HWMP. She is secured with “lay-up” moorings at all times with the exception of the first 48 hours after returning from cruise, shipyard, or other deployment and the 48 hours preceding such evolutions. If heavy weather is predicted during these periods (Condition XRAY), and if the vessel will not put to sea, the vessel’s standard permanent mooring arrangement shall be deployed.

Section 5: Advisory Definitions Each of the following heavy weather advisory formats has merit. For the purposes of this heavy weather mooring plan, USCG COTP Marine Safety Advisories determine response. When hurricane conditions are anticipated, timing is more critical than the exact wind speed indicators.

1. USCG COTP Marine Safety Advisors are based on a minimum hurricane force wind of 64 KTS (74 MPH) arriving at a particular approaching time spread.

2. NOAA Heavy Weather Definitions take into account varying predicted wind force and approaching time spread.

3. MARAD Hurricane Levels of Preparedness focus on approach time without defining wind speeds.

Tropical Storm Warning Actions

1. Preceded by activities initiated for TROPICAL STORM WATCH

2. MARAD Marine Surveyor shall report the vessel’s status to MARAD DAO.

D. Hurricane Watch Definition: National Hurricane Center announcement that hurricane conditions (sustained winds of 64 KTS, 74 MPH or higher) are possible within the specified area in association with a tropical, subtropical, or post-tropical cyclone. Because hurricane preparedness activities become difficult once winds reach tropical storm force, the hurricane watch is issued 48 hours in advance of the anticipated onset of tropical-storm-force winds. (Approximates USCG COTP Condition WHISKEY to XRAY Status. Approximates USCG COTP Alert Status YANKEE TO ZULU).

Applicability to FREEDOM STAR in Home Port The FREEDOM STAR mooring arrangement must be augmented under Hurricane Watch and Hurricane Warning conditions.

A HURRICANE WATCH shall include those areas defined by the National Hurricane Center. However, the following advance preparations shall be accomplished when and if a HURRICANE WATCH is displayed for “designated coastal areas” that include Pamlico Sound, NC and Chesapeake Bay.

Training Ship Hurricane Watch Actions

19. At least one (1) fire warp is rigged on the bow and another on the stern. In order to expedite the establishment of an emergency tow, a portion of each fire warp should be draped overboard and allowed to hang no more than six (6) feet above the waterline.

E. Hurricane Warning Definition: National Hurricane Center announcement that hurricane conditions (sustained winds of 74 MPH, 64 KTS or higher) are expected somewhere within the specified area in association with a tropical, subtropical, or post-tropical cyclone. Because hurricane preparedness activities become difficult once winds reach tropical storm force, the hurricane watch is issued 36 hours in advance of the anticipated onset of tropical-storm-force winds. The warning can remain in effect when dangerously high water or a combination of dangerously high water and waves continue, even though winds may be less than hurricane force.

Applicability to FREEDOM STAR in Home Port The FREEDOM STAR mooring arrangement must be augmented under Hurricane Watch and Hurricane Warning conditions.

A HURRICANE WARNING shall include those areas defined by the National Hurricane Center. However, the following advance preparations shall be accomplished when and if a HURRICANE WARNING is displayed for “designated coastal areas” that that include Pamlico Sound, NC and Chesapeake Bay (USCG COTP Condition ZULU Status).

17. Dog Main Deck watertight doors (if so directed by Master).

18. At least one (1) fire warp is rigged on the bow and another on the stern. In order to expedite the establishment of an emergency tow, a portion of each fire warp should be draped overboard and allowed to hang no more than six (6) feet above the waterline.

F. Extreme Wind Warning Definition: National Hurricane Center announcement that extreme sustained winds of a major hurricane (115 MPH, 100 KTS or greater), usually associated with the eye wall, are expected to begin within the hour. Take immediate shelter in the interior portion of a well-built structure.

Applicability to FREEDOM STAR in Home Port The FREEDOM STAR mooring arrangement must be augmented under Hurricane Watch and Hurricane Warning conditions.

An Extreme Wind Warning is issued for a specific area of anticipated threat. All personnel on board and pier-side shall take shelter. When and if an Extreme Wind Warning is issued, all HWMP preparations should be complete. During the evolution of an Extreme Wind Warning, it will likely be impossible and certainly highly dangerous for personnel to venture outside of secure shelter. Docking lines and wires may come under severe strain with danger of catastrophic failure. The pier apron is likely to be flooded. The air is likely to be filled with flying debris. (USCG COTP Condition ZULU) In “extremis” storm situation, events are likely to occur that are unexpected and outside the scope of a written document. Communication is an extremely important component of successful mitigation of damage and survivability of a vessel’s mooring system.

1. The particular mooring location of the FREEDOM STAR is well sheltered from high sea conditions. Wind exposure, particularly from the south and southeast in the case of a cyclical low passing to the west of Chesapeake Bay is a potential threat. However, a primary concern will be the storm surge likely in this scenario.

2. A cyclonic storm passing to the east will result in winds backing from NE thru N to SW initially pushing the FREEDOM STAR off the pier and continuing to push her NE parallel to the pier face as the storm passes.

3. A cyclonic storm passing to the west historically creates winds veering from E thru SE to SW. These wind directions will initially tend to push FREEDOM STAR onto and then parallel to the pier. Major pier flooding and unsustainable strain on any short mooring lines are distinct possibilities.

G. Winter Nor’easters Definition: Heavy Weather Systems other than tropical or post-tropical cyclonic storms are not an unusual event in this venue. Each winter brings one or more storms, often with associated blizzard conditions and, more often than not, with winds loaded with moisture coming in from the northeast off the ocean.

Applicability to FREEDOM STAR In Home Port:

It is not unusual for a Nor’easter to create an unusually high tide the Piney Point, MD location where FREEDOM STAR is moored. Winds blowing parallel to the pier against relatively shallow raft vessel with high windage can create significant strain on mooring components.

Preparations for Northeast storm conditions should follow, in general, the sequence of events for Tropical Storm and Hurricanes detailed in the preceding sections, as required.

Section 7: MARAD Hurricane Levels of Preparedness Preparations for the MARAD Hurricane Levels of Preparedness essentially mirror the preparations described in Section III for Tropical Depression thru Hurricane and Extreme Wind Warnings, the categories delineated by the National Weather Bureau.

Condition Four – Alert Definition: Threatening winds, sustained at 34 knots, are possible within 72 hours (Arrival Time Based -- Approximates USCG COTP Condition WHISKEY)

Condition Three – Watch Definition: Threatening Winds Are possible within 48 hours.

(Arrival Time Based -- Approximates USCG COTP Condition XRAY)

Condition Two – Warning Definition: Threatening winds are possible within 24 hours (Arrival Time Based -- Approximates USCG COTP Condition YANKEE)

Condition One – Maximum Preparedness Definition: Threatening winds are possible within 12 hours (Arrival Time Based -- Approximates USCG COTP Condition ZULU)

Post Hurricane Actions Inspect for damage. Notify port authorities of conditions that are a threat to life, property, or the environment. This includes, but is not limited to, USCG, COTP, and ABS.

Section 8: USCG Weather Event Definitions The following definitions are partially redundant to the foregoing. However, they are included as adding value to the understanding of various terminologies associated with weather events.

Blizzard Warning Issued for sustained or gusty winds of 35 mph or more, and falling or blowing snow creating visibilities at or below ¼ mile. These conditions should persist for at least three hours.

CART (Common Assessment and Reporting Tool) A web-based system used by the Coast Guard as a repository of Marine Transportation System Recovery information. CART assists the Maritime Transportation System Recovery Unit (MTSRU) in making MTS Recovery recommendations to the Unified Command and facilitates MTS Recovery Operations. CART also aids in situation reporting utilizing Essential Elements of Information to provide status updates on the MTS and critical infrastructure.

Cyclone An atmospheric disturbance marked by masses of air rapidly circulating counter-clockwise (in the Northern Hemisphere) about a low pressure center and/or a violent rotating windstorm.

Danger-Quadrant/Dangerous Semicircle The northeastern quadrant or right-hand semicircle of a hurricane having the highest winds/seas.

Extra-Tropical Cyclone Is the much larger scale, usually less intense, frontal cyclone of middle latitudes. These cyclones lie outside the scope of the Hurricane Warning Service - although many Tropical and a few Subtropical Cyclones adopt Extra-tropical characteristics or merge with existing Extra-tropical cyclones before dissipating, if they move sufficiently far north to encounter cold air.

Flash Flood Watch A flash flood watch means a flash flood is possible in the area. Stay alert.

Flash Flood Warning A flash flood warning means a flash flood is imminent. Everyone in the area should take immediate action.

Floods Water Water overflowing onto normally dry land.

Flood Tide Rising tidal flow.

Freezing Rain Rain that falls onto a surface that has a below freezing temperature. This causes rain to freeze to surfaces, such as trees, cars, and roads, forming a coating or glaze of ice. Even small accumulations of ice can cause a significant hazard.

Gale Warning An advisory of strong winds. The advisory is given when winds 39 to 54 miles per hour (34 to 47 knots) are forecasted or are occurring.

Hurricane A severe tropical cyclone in which winds spiral counterclockwise around a core or "eye" of low pressure, with maximum wind velocities 74 miles per hour (64 knots) and higher.

Hurricane Eye An area of light to calm winds with partly cloudy skies at the center of a cyclonic storm circulation. One of the criteria for upgrading a tropical depression to a tropical storm is the formation of an eye.

Hurricane Season In the North Atlantic, a period between 1 June through 30 November.

Hurricane Warning A hurricane warning is issued when a hurricane with sustained winds of 74 mph (64 knots) or higher is expected in a specified coastal area in 36 hours or less. A hurricane warning can remain in effect when dangerously high water or a combination of dangerously high water and exceptionally high waves continues even though the winds may have subsided below hurricane intensity. When a warning is announced, it is of utmost importance that precautionary measures are taken for protection of life and property.

Hurricane Watch An advance statement, not a warning, indicating that a hurricane is approaching and attention should be given to subsequent advisories. A hurricane watch is issued for a specified coastal area for which a hurricane or a hurricane-related hazard is a possible threat within 48 hours. Precautionary action should be taken in case hurricane warnings are forthcoming.

Inland Warning – Inland Watch – Inland Hurricane Inland Tropical Storm Warning – Inland Tropical Storm Watch Issued for interior counties under the same criteria as a Hurricane or Tropical Storm Watch/Warnings.

Natural Disaster Widespread or severe damage, injury, or loss of life or property resulting from any natural or man-made cause, including but not limited to fire, flood, earthquake, storm, wind, wave action, oil or hazardous substance discharge or other water contamination requiring emergency action to avert danger or damage, volcanic activity, epidemic, air contamination, blight, drought, accident, infestation, or explosion.

Nor’easter A low pressure disturbance forming along the South Atlantic coast of the U.S. and moving northeast along the Middle Atlantic and New England coasts to the Atlantic Provinces of Canada. It usually causes strong northeast winds with rain or snow and coastal flooding and beach erosion. These storms are also known as Northeasters or Coastal Storms.

Post-Tropical Storm Any system that no longer possesses sufficient tropical characteristics to be considered a tropical cyclone. Post-tropical cyclones can continue to carry heavy rains and strong winds. Some post-tropical cyclones will go on to become fully extra-tropical, that is, continuing to derive their energy from the temperature contrast between warm and cold air masses. Another type of post-tropical cyclone is the "remnant low," a weak system with limited thunderstorm activity and winds of less than tropical storm strength.

Recovery The process of returning Marine Transportation System (MTS) infrastructure (ATON, Waterways, Bridges, etc.) to a status that allows port facilities to operate and transportation to return to “near normal.” This is accomplished through activities and with resources controlled either by the Coast Guard or by agencies and industry partners with whom we have pre-established working relationships. Recovery efforts can typically be completed within 90 days of an incident.

Re-Curvature The natural tendency of a tropical cyclone to curve to the right in the northern latitudes.

Restoration: The process of returning the Marine Transportation System to pre-incident capacity. Restoration can be a much longer-term effort and is often governed by factors well beyond port level Coast Guard control. It may require initiatives governed by regional or national level interagency policies.

Seiche A wave that oscillates in partially or totally enclosed bodies of water from a few minutes to a few hours. A seiche is caused by seismic or atmospheric disturbances.

Sleet Rain drops that freeze into ice pellets before reaching the ground. Sleet usually bounces when hitting a surface and does not stick to objects. However it can accumulate like snow and cause a hazard to motorists.

SLOSH

The output of the NOAA storm surge prediction model SLOSH (Sea, Lake, and Overland Surges from Hurricanes).

Snow Flurries Light snow falling for short durations. No accumulation or light dusting is all that is expected.

Snow Showers: Snow falling at varying intensities for brief periods of time. Some accumulation is possible.

Snow Squalls Brief, intense snow showers accompanied by strong, gusty winds. Accumulation may be significant.

Storm Surge A rapid rise in the water level above the normal tide level due to the effects of high velocity winds and low barometric pressure on the water surface.

Storm Tide The actual level of sea water resulting from the astronomic tide combined with a storm surge.

Storm An atmospheric disturbance manifested by strong winds accompanied by rain, snow, or other precipitation and often by thunder and lightning.

Tornado A rotating column of air usually accompanied by a funnel-shaped downward extension of a cumulonimbus cloud and having a vortex several hundred yards in diameter whirling destructively at speeds of up to 300 miles per hour (261 knots). Tornadoes are rated on the Fujita scale, a three-decade-old system of ranking their strength based on estimated wind speeds and damage. The National Weather Service revised the scale in February 2006 to align wind speeds more closely with actual damage.

The new system (Enhanced Fujita Scale – EF) went into effect February 1, 2007. EF is a set of wind estimates (not measurements) based on damage. It uses three-second gusts estimated at the point of damage based on a judgment of 8 levels of damage to the 28 indicators. These estimates vary with height and exposure.

Tornado Watch Issued to alert the public that conditions are favorable for the development of a tornado in and close to the watch area. These watches are issued with information concerning the watch area and the length of time they are in effect.

Tornado Warning Issued by local NWS offices to warn the public that a tornado has been sighted by storm spotters, law enforcement or has been indicated by radar. These warnings are issued with information concerning where the tornado is presently located and which communities are in the anticipated path of the tornado.

Tropical Depression A tropical cyclone with a maximum surface wind speed of 38 miles per hour (33 knots) or less which is expected to increase to storm intensity Tropical Storm A distinct low-pressure area defined by a counterclockwise rotation and winds of 30 to 74 miles per hour (26 to 64 knots).

Tropical Storm Warning An alert that tropical storm conditions, including sustained winds of 39 to 73 miles per hour (34 to 63 knots), are expected in specific areas within 36 hours.

Tropical Storm Watch A tropical storm watch is issued when tropical storm conditions, including winds from 39 to 73 miles per hour (34 to 63 knots), pose a possible threat to a specified coastal area within 48 hours.

Wavelet A small wave or ripple.
