REQUIREMENT

1. Background: The Military Sealift Command (MSC) requires Contractor support for the development of the TRANSALT work packages outlined in the Enclosures (1) and (2).

This PWS details the standard deliverables that are generated when developing a

TRANSALT. This PWS is used in conjunction with the Enclosures and detailed in the

Enclosures themselves. The Enclosures call out the required deliverables as defined in this

PWS and also identify any non-standard deliverables that are necessary for development of a TRANSALT.

2. Scope: MSC requires Wartsila OEM professional engineering services to design and develop ABS approved TRANSALT work packages required for the execution of several modifications onboard the TAO-205 Class.

Enclosure (1): TAO-205 0046 MAIN REDUCTION GEAR HEAD TANK

REQUIREMENTS

T-ALT NUMBER: TAO-205 0046

SHIP NAME/CLASS: TAO-205 CLASS

Abstract: The Main Reduction Gears (MRG) on the T-AO 205 Class do not utilize a head tank arrangement for lube oil supply as has been installed on other classes of vessels, including the

187 Class Oiler that the 205 Class will replace. The addition of a head tank on the 205 Class

MRG Lube oil system would provide several benefits:

1) Allow for robust monitoring of MRG lube oil levels

2) Allow for passive flow of Low Pressure lube oil to the mesh and bearing lubrication system in the event of loss to the LP lube oil Supply system over a designed amount of time

3) Allow for robust system of safety system sensors to prevent inadvertent activation of

MRG Low-Low lube oil pressure safety shaft lock automated sequence (non-over rideable)

4) Allows for designed amount of additional lube oil supply once a critical low level alarm set point is reached

On the 187 class, this combination of design factors was used to provide a level of built in lube oil margin for the in conjunction with the vessel’s automated safety system to protect the MRGs in critical maneuvering scenarios. When a “Low-Low Level” switch is activated in the head tank, the vessel has 6 minutes of lube oil supply volume below that level. In combination with a feature called the “UNREP Switch” which, when activated, delays the MRG auto-brake sequence for low lube oil. The goal of the UNREP switch in combination with the physical supply of lube oil below the sensor is to allow for 5 minutes of continued operations to perform an emergency breakaway. The 6 minute of lube oil is sized for 5 minutes of operations and then

1 minute for the automation sequence to declutch and brake the shaft.

The head tank shall be provided with a tank level monitoring system as well as level switches that can be used for the propulsion control automated safety system. The Switches shall indicate a “Low Level” and a “Low-Low Level”. The “Low-Low Level” switch shall be placed such that the quantity of oil between the level switch and the gravity line to the MRG provides 5 minutes of lube oil supply at rated Low Pressure lube oil when the clutch system is engaged to the prime movers. Additionally, the head tank margin below the

“Low-Low” switch shall include sufficient lube oil needed for the amount of time necessary for automations to disengage the shaft line, slow and stop the shaft.

The Wartsila MRGs used on 205 also have High Pressure Lube Oil system pumps that are used to operate the attached clutches. These pumps also take suction from the common MRG sump and need to be accounted for in the consumption rate of the overall lube oil system and the sizing of the lube oil head tank. The sizing of the head tank needs to be a balance to ensure the head tank does not flood the sump of the

MRG when the system is not in operation or the pumps are not running.

The design of the head tank should be accomplished in close coordination with the OEM of the gearbox (Wartsila) to ensure the OEM will support the design implementation or if they have an existing design for a head thank solution. The OEM should also be consulted to determine if a COTS solution is available

E1-2.1. Discipline Specific Considerations:

E1-2.1.1. Arrangements and Outfitting: Location of the head tank and associated pipe routing to the MRGs.

E1-2.1.2. Structural: Provide sufficient support for pipes to prevent vibration but allow for any necessary flexibility of the system from MEG vibration and ship’s motion. If necessary, provide sufficient foundation structure for the head tank.

E1-2.1.3. Mechanical: Suitability of the current MRG lube oil pumps needs to be investigated to determine if the current pumps can be used to feed the lube oil to the necessary head tank height. If lube oil pumps are not sufficient then a recommendation on replacement pumps should be included.

E1-2.1.4. Electrical: Provide necessary power, control and signal cables for monitoring devices associated with the new head tank. If mechanical determines that new pumps are needed, an assessment of the current electric motors, motor controllers and feed power should be looked at. The each MRG has a PLC that controls the logic for the duty/standby pumps; the design of the head tank monitoring should include any necessary changes to the PLC logic to ensure satisfactory operation.

E1-2.1.5. Automation Modifications: None additional.

Enclosure (2): TAO-205 00047 MAIN REDUCTION GEAR SENSOR REDUNDANCY

REQUIREMENTS

T-ALT NUMBER: TAO-205 0047 MAIN REDUCTION GEAR SENSOR REDUNDANCY

SHIP NAME/CLASS: TAO-205 CLASS

Abstract: The Main Reduction Gears (MRG) on the T-AO 205 Class utilize a skid mounted

PLC system to collect sensor data, which is used as part of the lube oil pump start logic, clutch engagement and MRG’s safety monitoring, alarm and shutdown system. Loss of Lube Oil pressure is considered a critical, non-over ridable, safety alarm per ABS SVR 4-9-2. To monitor

Low Pressure System (gear mesh and bearing lubrication) lube oil pressure the MRG utilizes two (2) separate types of sensors. A pressure transducer (“L01”) is used for monitoring and outputs a 4-20 mA signal to the PLC system (which is relayed to the Machinery Centralized

Control System (MCCS)) to provide an analog reading of the dynamic system pressure. MCCS has alarm set points set for assigned to critical pressure values from the analog signal. Two (2) additional calibrated pressure switches are used to the safety shutdown system. Pressure switch

“L04”is calibrated for a low-low pressure shutdown at 0.6 bar and the signal is routed directly to the Main Diesel Engine’s (MDE) safety and control system (SaCoSone). Activation of “L04” will cause SaCoSone to initiate and emergency shutdown of the MDE and an alarm will output from SaCoSone via a serial interface to MCCS indicating a shutdown on low MRG lube oil pressure. Pressure switch “L012” performs a similar function, but it provides an output to the

Shaft Generator Motor’s (SGM) Drive Control Unit to shut down the SGM.

Neither the analog pressure transducer or the safety shutdown pressure switches (“L04” and

“L012”) are routed directly to the Propulsion Control System Data Acquisition Units

(Port/STBD Propulsions DAUs). The PCS can monitor the serial alarms and analog pressure signal over the MCCS network backbone, but PCS (the dedicated PCS PLC’s) will take action based on these signals to provide subsequent automation to meet ABS requirements for AMS and ACCU. PCS will initiate automatic load reductions and automatic shaft brake sequences based on values given by the pressure transducer (“L01”). The MDE shutdown is handled solely by SaCoSone and is based on the single input from sensor “L04” (similarly for the SGM shutdown). PCS processes a combination of “L01” and MDE serial output alarms to initiate an automated sequence to declutch, slow and lock the affected shaft to protect the MRG from operating without sufficient lube oil pressure. The automatic shaft break sequence on Low-Low lube oil pressure is a non-over ridable sequence to meet the requirements of ABS. The shutdown of the MDE (and SGM) are non-over ridable as well in accordance with ABS.

It is determined to be an operational risk that a single sensor failure or faulty activation could result in a non-over ridable loss of propulsion. In high risk, critical maneuvering scenarios (such as an UNREP), the sudden loss of propulsion could result in the vessel losing course keeping and result in a collision. Additional redundancy of sensors driving a non-over ridable safety automation sequence would prevent a single point of failure.

E2-2. Scope of Work: The Contractor shall investigate and provide a scope of work to add redundancy to the safety sensor system on the MRGs to remove single point of failure concerns. The MRG OEM (Wartsila) shall be contacted to determine if there is a

COTS solution for additional sensor redundancy. If a non-OEM solution is required, investigation should look at the potential of using the currently installed transducers and switches in combination to the greatest extent possible to limit the amount of physical modification to the lube oil piping. If the existing sensors can be used, provide a work package of wiring changes (such as the addition of relays if needed) and/or necessary software modification specification for modifications to the Propulsion Control System in order to achieve redundancy.

If utilizing the current sensors is not feasible, provide a work package for installation of necessary sensors, wiring and software change specifications to update the current design to meet the needed redundancy.

The MRG safety system should utilize at least two (2) positive signals (configured in a fail-safe arrangement with the physical sensors) to initiate any safety shutdown of the

MRG. This includes automatic declutching (loss of High Pressure Lube Oil pressure);

Low Pressure System shutdowns (MDE shutdown output signal (“L04”); and signals processed by PCS for shaft locking sequence.

The work item will require coordination between the MRG OEM; the engine controls manufacturer (Fairbanks Morse Engines) and the control and automation system OEM

(Trident Marine Systems). Modifications must meet the design requirements of ABS

AMS and ACCU notation and applicable SVRs. If a design constraint requires a deviation from the rules, a specific “UNREP Mode” should be created to allow the system to go between maximum redundancy and full ACCU/AMS compliance. This deviation needs to be presented to MSC for potential to route through USCG in a

Memorandum of Understanding.
