044 [Orig] RB-M OPERATION

044-1 [Orig] Concept of Operations

044-1.1 [Orig] The RB-M shall be a multi-mission capable boat operable from Coast Guard shore stations. The RB-M will normally be in the water and be ready to rapidly respond to any Coast Guard mission on very short notice or to conduct planned patrols and training. The primary role of the RB-M in these missions follows:

044-1.1.1 [Orig] Search and Rescue (SAR) – As the primary response asset at a Coast Guard station, the RB-M will be required to conduct a wide variety of SAR missions. Typical missions will require the RB-M to rapidly get underway in response to a distress call, transit at the highest possible speed to a search area, conduct a search, and perform a rescue mission. Throughout the mission, it is vital that the RB-M crew be able to efficiently navigate the RB-M using real time data and displays with input from a number of navigational sensors. At the same time, the crew shall be able to intercommunicate and maintain communications with Coast Guard command and control elements including stations, groups, aircraft and cutters. The crew shall also be able to communicate with the person or vessel in distress, and other vessels or persons assisting in the SAR effort. Once the RB-M arrives on scene, the actions taken vary widely, but may include:

044-1.1.1.1 [Orig] Recovery from the Water – The RB-M shall be capable of retrieving people (able-bodied, unconscious or deceased) or material from the water. Typical operations involve the RB-M maneuvering into the prevailing wind or creating a lee where the rescue is to take place. Methods of recovery may vary depending on the RB-M design; however, no more than two crewmembers will be available to conduct the recovery operations. In the case of a man overboard where one or more Coast Guard crew ends up in the water, it is important that they be able to get themselves back onboard unassisted.

044-1.1.1.2 [Orig] Transfers – The RB-M shall be capable of transferring crewmembers, other personnel, and equipment to and from another vessel to help provide damage control or medical assistance. Typical transfers include providing a crewmember for onboard assistance, providing the Coast Guard P-6 dewatering pump, or moving an injured person in a Stokes litter. Transfers will normally be conducted directly by coming alongside the other vessel or, when necessary, equipment will be transferred via water using tending lines. In the case of the water transfer, a line is attached to the piece of equipment (typically a dewatering pump in a watertight container) and the line is passed to the disabled vessel. The equipment is then lowered into the water and hauled to the other vessel. An additional line will lead back to the RB-M to help guide and recover the piece of equipment. A similar method is also occasionally employed for passing a salvage pump down the towline to another vessel. The RB-M is also expected to be a boarding platform for transferring personnel to assist people, minimize damage to property, and conduct inspections to ensure compliance with federal laws and regulations, or enforce laws. Generally, boarding operations are conducted with the RB-M and vessel to be boarded underway at speeds up to 9 knots, following a course deemed safe and suitable for the safety of all personnel. Boarding of vessels by the RB-M crew while both are underway requires that the RB-M helmsman match the speed of the vessel to be boarded while contacting the other vessel's hull at an angle to keep the vessels together. Upon completion of the boarding or transferring of equipment, the RB-M helmsman shall break contact with sufficient speed and power to safely withdraw from the vicinity of the other vessel without causing damage to either the RB-M or the other vessel. Vessels not underway or incapable of getting underway will also be boarded from the RB-M.

044-1.1.1.3 [Orig] Towing – The RB-M shall be capable of towing disabled vessels astern and alongside. Typically, tows will be conducted astern until the RB-M reaches restricted waters or is maneuvering into a slip or alongside a dock. Aft tows can be connected directly to the end of the towline, or by using a bridle or pendant when the vessel being towed is not suitable for an easy towline connection. The towing line is passed to the disabled vessel by first passing a heaving line and then using the heaving line to pull the towline to the disabled vessel. Good communication between crew and helmsman during the towing operation is critical to success, particularly when high winds and seas are present.

044-1.1.1.4 [Orig] Helicopter Operations – The RB-M crew shall be capable of transferring people and equipment to and from Coast Guard helicopters. Personnel transfers are done using a rescue device (a rescue strop, a rescue basket or a Stokes litter). Equipment transfers are similar except the equipment may be directly connected to the hoist line. Typical operations will require the RB-M to maintain a steady course, with the wind off of the port bow, while the helicopter is maneuvered off of the port stern quarter. Transfers are either done directly or using a trail line. The helicopter trail line is a light line with a 5-pound weighted bag on the end that is lowered to the boat. The other end is attached to the rescue device via a weak link. The RB-M crewmember will be required to retrieve the trail line and use it to guide the rescue device to the deck. In order to discharge the static electricity that may build up in the helicopter and rescue device, the rescue device is grounded using a grounding wand or by having the device touch the water or hull. Once the rescue device is loaded, the crewmembers help to guide it off the deck and tend to the trail line (if used) until it is clear of the boat.

044-1.1.1.5 [Orig] Medical Assistance – The RB-M shall have sufficient space to provide medical assistance to rescued persons. First aid is typically provided at the First Responder level; however, more advanced first aid may be conducted depending on the capabilities of the rescue personnel.

044-1.1.1.6 [Orig] Fire Fighting and Rescue Assistance – The RB-M’s primary mission in fighting fires on other vessels is to save lives, not property, and to protect the RB-M in a hazardous environment. In this role, the RB-M shall be capable of coming alongside another vessel to retrieve persons in danger. Limited fire suppression may be provided using portable fire extinguishers or by rigging the dewatering pump with a fire hose and nozzle to provide a protective spray of water.

044-1.1.2 [Orig] Recreational Boating Safety (RBS) – The RB-M crew shall be capable of conducting RBS missions. Typical tasks include patrolling designated areas to monitor boating safety, conducting boardings and inspecting vessels for compliance with federal laws, and enforcing safety and security zones for recreational events. RBS missions are normally only conducted in calm and moderate sea and wind conditions to reduce the risk of injury to the personnel involved and damage to the boats.

044-1.1.3 [Orig] Marine Environmental Protection (MEP) – The RB-M shall be capable of supporting MEP missions. In many cases, the RB-M may provide the first line of defense in the MEP program by being the first to respond to a reported incident and coordinating the subsequent actions. The RB-M may be tasked with conducting routine MEP patrols, towing oil containment booms, and transferring specialized personnel and equipment to the incident scene. Transfers are typically conducted in manners similar to those used in a SAR mission. In addition, the RB-M may be the on-scene command vessel coordinating the actions of others, or be required to enforce safety zones around an environmental incident.

044-1.1.4 [Orig] Enforcement of Laws and Treaties (ELT) – The RB-M shall be capable of conducting ELT missions. The ELT program emphasis is on protecting living marine resources, preventing illegal drug trafficking, interdicting undocumented migrants at sea, and enforcing a wide range of federal laws and treaties. In performing these missions, the RB-M shall be capable of: conducting patrols; monitoring illegal activity; coming alongside other vessels for boardings; interdicting potentially hostile vessels; detaining suspects or migrants onboard for transport to shore or to another vessel; and recovering undocumented migrants or contraband from the sea. Electronic communication with other Coast Guard and law enforcement assets, as well as the vessels under investigation, is vital to the mission. In addition, the RB-M shall be capable of projecting an effective projection of force to compel compliance with laws and treaties, to deter illegal activity, and to disable hostile or evasive targets. This projection of force may be provided by hand-held small arms as well as mounted light machine guns. During these operations, it is vital that the crewmembers on deck are able to maintain communication with the helmsman.

044-1.1.5 [Orig] Ports, Waterways and Coastal Security (PWCS) – The RB-M shall be capable of conducting PWCS missions. The PWCS missions primarily involve maintaining the safety of ports through the prevention of accidental damage to vessels and port facilities and preventing the intentional destruction, loss or damage to port assets and vessels as a result of terrorism or sabotage. In conducting these missions, the RB-M shall be able to: conduct routine patrols; enforce security zones; come alongside other vessels, including large ships, for boardings; monitor illegal activity; detain suspects; and interdict potentially hostile vessels. Similar to the ELT mission, the ability to communicate with other assets and the ability to project an effective projection of force are vital to the PWCS mission. The RB-M shall also be road transportable to allow the RB-M fleet to be relocated in response to both planned and emergency events that require PWCS.

044-1.1.6 [Orig] Defense Operations (DO) – The RB-M shall be capable of conducting missions in support of DO within the coastal waters of the United States and its territories. In support of these missions, RB-M shall be capable of: conducting routine patrols; enforcing security zones; coming alongside other vessels, including large ships, for boardings; monitoring illegal activity; detaining suspects; interdicting potentially hostile vessels; and disabling hostile or evasive targets. Similar to the ELT and PWCS missions, the ability to communicate with other assets and the ability to provide an effective projection of force are vital to the DO mission.

044-1.1.7 [Orig] Other Missions – As a multi-mission capable asset, the RB-M may be required to conduct a wide range of other missions. These may include transporting specialized aids-to-navigation teams to verify aid locations, transferring specialized personnel to other vessels and structures, and serving as a platform for public relations activities.

044-1.2 [Orig] The RB-M shall be capable of operations with a minimum complement of three – a coxswain, a qualified engineer and one crewmember. However, many missions require one additional special operations crewmember. In these instances, the RB-M complement will be four people.

044-1.3 [Orig] The coxswain is the person responsible for the primary operation of the RB-M. The coxswain’s responsibilities include steering, propulsion controls, course keeping, and overall command of the RB-M. While the coxswain may be the one that drives the RB-M, the coxswain may also delegate this duty to one of the other crewmembers. For that reason, this Specification will refer to the person driving the RB-M as the helmsman.

044-1.4 [Orig] The crew will assist the helmsman in safe navigation, operating the radios and electronic navigation equipment, and conducting all mission related activities.

044-1.5 [Orig] The engineer is the person responsible for monitoring the condition of the propulsion machinery. The engineer makes routine inspections of machinery spaces while underway.

044-1.6 [Orig] The RB-M special operations crewmembers may be required to man and operate machine guns mounted on the vessel. Operations involving the use of the machine gun frequently are conducted while the RB-M is making way, and could involve the RB-M approaching a target directly or at an angle.

044-1.7 [Orig] Further information on standard Coast Guard boat operation practices is available in COMDTINST M16114.5C, COMDTINST M16114.32 and COMDTINST M16114.33.

044-2 [Orig] Survivability

044-2.1 [Orig] As a multi-mission Coast Guard asset, the RB-M will be required to perform in a wide range of conditions. While every effort will be made to ensure the RB-M operates within its designated Mission Capable limits as shown in Figure 044‑1, there will be times when the RB-M is forced outside these limits through the unpredictability of weather, rapidly changing sea conditions, hostile intent of others, system or component failures and human error. Thus, it is imperative that the RB-M provide a level of survivability beyond the required Mission Capable limits to ensure the safety of the crew. The following shall be considered in the development of the RB-M:

044-2.1.1 [Orig] Extreme Seas and Winds: The RB-M shall have the capability to survive in extreme sea and wind conditions up to the Survivable limits shown in Figure 044‑1.

044-2.1.2 [Orig] Flooding and Damage Control: The RB-M shall have the ability to survive flooding caused by component failure, hull damage or hostile fire. This includes an alarm system (see Section 436) and a bilge system to remove water (see Section 529), and ultimately enough reserve buoyancy, stability and compartment watertight integrity to withstand flooding of any single main compartment (see Section 079). Fendering shall not be considered in the determination of damage survivability.

044-2.1.3 [Orig] Fire: The RB-M shall have the capability to detect and suppress onboard fires (see Section 436 and 555).

044-2.1.4 [Orig] Emergency Systems: The RB-M shall be provided with a means to maintain radio communication, provide limited navigation using GPS, provide emergency and navigation lighting, and maintain propulsion control for at least four hours in the event the primary electrical power generation system fails (in accordance with section 313).

044-2.1.5 [Orig] Crew Egress: In the event of fire, capsize or other event that may cause the RB-M to be unsafe for its crew, it is vital that the crew be able to safely and rapidly get out of all internal compartments, including machinery spaces, and be prepared to leave the RB-M.

044-2.1.6 [Orig] Liferaft: If the RB-M is not self-righting, then a liferaft shall be provided and located so that it can be rapidly deployed (see Section 583).

044-2.1.7 [Orig] Shelter in Place: The RB-M shall be capable of providing minimal “shelter in place” protection to protect the crew from hazardous operating environments. This includes watertight doors and windows (see Sections 167 and 625) and the ability to completely seal off the ventilation system to manned spaces for limited amounts of time in emergency situations (see Section 512).

Figure 044‑1 Sea State Limits

044-3 [Orig] Areas of Operation

044-3.1 [Orig] The RB-M will be expected to operate in the Coastal Zone of the United States and its territories, which includes inshore and inland waterways and open ocean out to 50 nautical miles from the coastline. The RB-M will operate routinely in shallow water. The RB-M is not intended to be operated in the surf.

044-3.2 [Orig] The RB-M will be expected to conduct missions up to the Mission Capable limits shown in Figure 044‑1.

044-3.3 [Orig] The RB-M will be expected to survive up to the Survivable limits shown in Figure 044‑1.

044-4 [Orig] Annual Hours of Operation and Mission Profile

044-4.1 [Orig] The RB-M is anticipated to operate approximately 600 hours per year and may be stored uncovered in the water for the remainder of the time.

044-4.2 [Orig] Ope rational Availability – The RB-M shall have an average annual operational availability of at least 80%. Operational availability (Ao) is defined as:

Ao=	Operational Time	=	(To+Ts)
	Total Time		(To+Ts+Tm+Tl+Ta)

Where:

To = Operating Time (hours)

Ts = Standby Time (B – 0 status) (hours)

Tm = Maintenance Time (preventive and casualty) (hours)

Tl = Logistical Delay Time (hours)

Ta = Administrative Delay Time (hours)

044-4.3 [Orig] On an annual basis, the mission profile is expected to be as shown in Table 044‑1.

044-4.4 [Orig] The mission profile is an average breakdown. Individual sorties may have considerably different percentages depending on the mission conducted. Individual sorties are typically restricted to 10 hours or less underway time with both propulsion engines operating.

070-1.5 [Orig] Navigational Clearance – Clearance shall be measured from the static Minimum Operating Condition waterline to the tallest vertical extremity when the appendages are lowered and raised. Navigational clearance shall be achievable underway in restricted waters. No more than two crewmembers shall be required to raise or lower the appendages.

070-2 [Orig] General Arrangements

070-2.1 [Orig] The general arrangement of the boat shall allow for performance of the intended missions as described in Section 044.

070-2.2 [Orig] The pilothouse shall be outfitted with four forward-facing seats. For the purposes of this specification, the seats shall be designated for a helmsman, navigator, primary crewmember, and alternate crewmember. The pilothouse shall allow for maximum lines of sight to enable the helmsman and crew to operate the RB-M from the pilothouse. Lines of sight shall be maintained during all aspects of operations including high speed turns and increased trim while transitioning to planing speeds.

070-2.3 [Orig] There shall be interior space with seating for at least five passengers. This interior space shall be provided with fixed port and starboard windows or portlights to provide natural light.

070-2.4 [Orig] The RB-M shall have the ability to carry a casualty in a Stokes litter inside while providing medical assistance. The Stokes litter, when in use with a casualty, may take up to three passenger seats.

070-2.5 [A00014] The RB-M shall have sufficient deck space to conduct missions including helicopter recovery of a Stokes litter, law enforcement and defense operations, transferring portable mission equipment such as the P-6 salvage pump, and handling persons recovered from the water. Deck space shall be sufficient to allow easy passage around the RB-M, including passage alongside the pilothouse when alongside a ship or bulkhead, and passage when carrying the Stokes litter or P-6 pump. The aft deck shall be provided with handrails and/or lifelines around the deck perimeter.

088-1.1.12 [Orig] Design features to assure rapidity, safety, ease and economy of operation and maintenance in normal, adverse, and emergency maintenance environments.

088-1.1.13 [Orig] Compatibility of the design, location and layout of controls, displays, workspaces, maintenance accesses, stowage provisions, passenger compartments, allocated tasks, and control movements with the clothing and personal equipment to be worn by personnel operating, riding in, or maintaining the equipment.

088-1.2 [Orig] The Contractor shall evaluate and apply human systems integration processes, tools, and techniques in a continual fashion for each design modification/iteration throughout the acquisition cycle.

088-2 [Orig] Personnel

088-2.1 [Orig] Introduction of the RB-M system shall not require an increase in physical, sensory, or mental abilities of personnel responsible for operating, maintaining, or supporting the system.

088-3 [Orig] System Safety

088-3.1 [Orig] The RB-M system capability shall be such that system safety hazards associated with materiel shortcomings and impact on systems and human performance for all conditions, including but not limited to, handling, operational, maintenance, mission, meteorological, climatic, and emergency conditions are identified and eliminated or reduced to acceptable levels through engineering design and manufacture.

088-4 [Orig] Health Hazards

088-4.1 [Orig] The RB-M system capability shall be such that health hazards associated with, but not limited to, mechanical forces including shock and vibration; pressures; toxic, allergenic, pathogenic organisms and sanitation, or irritating substances; ionizing or non-ionizing radiation; noise or other emissions; combustion products; trauma; oxygen deficiency; heat stress, hypothermia or extreme temperatures and humidity throughout anticipated climatic conditions, either in operation, maintenance support, or emergencies are identified and eliminated or reduced to acceptable levels.

088-5 [Orig] Automation

088-5.1 [Orig] Functions shall be automated only to attain greater overall effectiveness, efficiency, reliability, simplicity, economy, and system safety. Irrespective of the level of automation, system and task design shall ensure that the human operator is in command, involved in ongoing operations, and appropriately informed to maintain awareness of the situation and other status of automated functions. When used, automated functions shall be predictable, offer the operator an appropriate range of options, monitor operator actions to minimize, resist, and tolerate errors, and be capable of being overridden by the operator in an emergency.

088-6 [Orig] Human Factors Engineering

088-6.1 [Orig] In accordance with ASTM F1166, the RB-M System shall be constructed to accommodate the 5th percentile adult female to the 95th percentile adult male in Coast Guard personal protective equipment including insulated flotation coveralls, survival vests, gloves, boots, side arms, and helmets.

088-6.1.1 [Orig] [Orig] Use of anthropometric data in design shall consider (a) the nature, frequency, safety, and difficulty of the related tasks to be performed by the operator or wearer of the equipment; (b) the position of the body during performance of these tasks; (c) mobility or flexibility requirements imposed by these tasks; and (d) increments in the design-critical dimensions imposed by the need to compensate for obstacles and projections.

088-6.2 [Orig] Because of the low correlation between strength and size, size shall not be used to determine accommodation of strength and endurance, rather, strength shall be considered separately. Specifically, it is very unlikely that operators and maintainers of minimum size also have minimum strength and endurance. Strength and endurance shall be separately accommodated for the range of male and female strength and endurance of the population.

088-6.2.1 [Orig] In general, controls requiring operator forces exceeding the strength limits of the fifth percentile strength segment of the expected user population shall not be used. High-force controls shall not be used except when the operator’s nominal working position provides proper body support or limb support or both, such as back or foot supports and braces. Sustained (durations longer than 3 seconds) high-force requirements shall be avoided.

088-6.3 [Orig] Insofar as possible, equipment design and installation shall provide the maintainer with complete visual and physical access and a favorable working level and safety/hazard precautions for all parts of a system on which maintenance is performed, including workstand interfaces, support equipment interfaces, access openings, adjustment points, test points, servicing points, and connections.

088-6.4 [Orig] Emergency shutdown devices, lockable controls, electrical cut-out switches, or warning signs or guards shall be positioned to ensure safety of maintainers when it is necessary to perform maintenance on or near a live/working system.

088-6.5 [Orig] Where visual access is required, the opening shall provide a visual angle sufficient to view all required information at the normal operating or maintenance position. Where bending is required, frequency and time in the bent position shall not cause fatigue.
