Section 90601

Career Sea Pay (TTC 139, 173, 147, 188) (Active Duty Only)

Section 1

Career Sea Pay (CSP) is special pay which is payable to Marines upon permanent or temporary assignment to sea duty.

a.  Under the requirements of the DOD 7000.14-R Financial Management Regulation, Volume 7A, Chapter 18, a Marine that is onboard ship for the purpose of transportation as a passenger is not entitled to career sea pay.  'Transportation as a passenger' is defined as Marines who are embarked aboard ship, as follows:

(1) on leave,

(2) on Permissive Temporary Additional Duty,

(3) on individual or unit overseas rotational assignment,

(4) or being transported while confined as a result of court-martial sentence.

Section 2

Marines serving onboard Category ‘A’ vessels receive continuous CSP.  The following vessels are designated as Category ‘A’:

(Note:  See paragraph #3 for Designated Afloat Staff Commands guidance.  See paragraph #5 for guidance pertaining to periods of assignment onboard a Category ‘A’ vessel during FMF deployment or temporary embarkation).

AS (SUBMARINE TENDER) CG (GUIDED MISSILE CRUISER) CVN (AIRCRAFT CARRIER NUCLEAR-POWERED) DDG (GUIDED MISSILE DESTROYER) EPF (EXPEDITIONARY FAST TRANSPORT) HST (HIGH SPEED TRANSPORT) LCC (COMMAND SHIP) LCS (LITTORAL COMBAT SHIP) LHA (AMPHIBIOUS ASSAULT SHIP GENERAL PURPOSE) LHD (AMPHIBIOUS ASSAULT SHIP MULTI-PURPOSE) LPD (AMPHIBIOUS TRANSPORT DOCK) LSD (DOCK LANDING SHIP) MCM (MINE COUNTERMEASURES SHIP) PC (PATROL COASTAL) T-AE (AMMUNITION SHIPS) T-AFSB (AFLOAT FORWARD STAGING BASE) T-AGOS (SURVELLANCE SHIP) T-AH (HOSPTIAL SHIP) T-AKE (DRY CARGO/AMMUNITION) T-AO (FLEET REPLENISHMENT OILER) T-AOE (FAST COMBAT SUPPORT) T-ARS (SALVAGE SHIP) T-ATF (FLEET OCEAN TUG) T-ATS (TOWING/SALVAGE/RESCUE SHIP) T-ESB (EXPEDITIONARY SEA BASE) T-ESD (EXPEDITIONARY TRANSFER DOCK)

Section 3

Marines assigned to Designated Afloat Staff Commands that are permanently embarked and serving in Category ‘A’ vessels are the only staffs authorized to receive continuous CSP.  All other Afloat Staffs receive the daily CSP rate (1/30 of month rate) only for days in which they are either underway, or embarked, and serving in a Category ‘A’ vessel.   The following Afloat Staffs, assigned to vessels of Forward Deployed Navy & Marine Corps Forces, and without working spaces ashore, are designated Category ‘A’:

COMSEVENTHFLT (Flag Allowance, Commander, 7th Fleet) CCSG-5 (Carrier Strike Group-5 – COMCARSTRKGUR FIVE)

(NOTE #1:  IT SHOULD BE NOTED THAT THE ONLY DESIGNATED AFLOAT STAFFS THAT RATE CONTINOUS CSP FOR THEIR ENTIRE TOUR ARE FOR MARINES ASSIGNED TO COMSEVENTHFLT AND CCSG-5. MARINES ASSIGNED TO ALL OTHER DESIGNATED AFLOAT STAFFS SUCH AS COMPHIBGRU, & COMPHIBRON, ONLY RATE CSP ON A DAY FOR DAY BASIS IN WHICH THEY ARE EITHER UNDERWAY, OR EMBARKED, AND SERVING IN A CATEGORY ‘A’ VESSEL FOR 8 CONTINUOUS HOURS).

(NOTE #2:  IF/WHEN TTC 139 SEQ 001 (START CARSEA DU), OR

TTC 147 SEQ 000 (CRED CARSEA DU), IS REPORTED FOR MARINES ASSIGNED TO A

DESIGNATED AFLOAT STAFF OTHER THAN COMSEVENTHFLT AND CCSG-5, MCTFS WILL SEND AN ADMIN RUC ADVISORY WITH NOTIFICATION THAT CSP ENTITLEMENT IS ONLY AUTHORIZED ON A DAY FOR DAY BASIS (1/30 OF MONTHLY RATE), AND ONLY FOR DAYS IN WHICH THEY ARE UNDERWAY, OR EMBARDED, AND SERVING IN A CATEGORY ‘A’ VESSEL FOR AT LEAST 8 CONTINOUS HOURS).

Section 4

Marines serving onboard Category ‘B’ vessels are eligible for the daily CSP rate (1/30 of monthly rate) when the member is embarked and serving in a Category ‘B’ vessel that is in a port more than 50 miles from the homeport of the vessel. Or, when the vessel is underway for 8 continuous hours.  The following vessels are designated Category ‘B’:

IX-21 (USS CONSTITUTION) TSV (THEATER SUPPORT VESSEL)

Section 5

Marines assigned to the Fleet Marine Force (FMF), who participate in an FMF deployment overseas/FMF operation or FMF field exercise that may or may not involve a movement aboard amphibious shipping, are eligible for the accumulation of deployed time and adjustment of their overseas control date.  Deployments that earn eligibility for accumulated deployed time should receive cumulative credit for sea duty service when the FMF deployment, operation, or field exercise involves embarkation aboard a United States Flagged Naval vessel (USCG, USS, USNS, STF) or when participating in a joint exercise and assigned to a Foreign Vessel).  (Note: See CSP TTC reporting guidance contained in paragraphs #7, #8, and #9).

Section 6

Career Sea Pay is composed of two elements, history and pay, which are computed on a 30-day month. Note:  For all CSP transactions with effective date of 31st day of the month, the 31st will display on the 907, 948, and 963 RMK’s, as well as the Career Sea Duty Display (CSPD) screen, even though pay entitlement FROM DATE starts on the 1st day of the next month. This paragraph contains the unit diary reporting requirements for career sea duty history and career sea duty pay.  The following definitions are provided for the terms and phrases used in this paragraph:  (Note: The Career Sea Duty Display (CSPD) screen was first introduced with SR 1-19 and can be found via the MCTFS PAY ASSISTANCE SUB MENU listed as CSPD – CAREER SEA DUTY CALCULATOR).

a.  Sea time/Sea days is the inclusive 'From' and 'To' dates of each period of career sea duty contained in MCTFS Career Sea History record (D963 RMK).

b.  Net sea time/Sea days is computer-generated and posted in MCTFS Career Sea History record (D963 RMK).  It is the total years, months, and days of each sea time period reduced by a day-for-day reduction for all periods of time lost occurring during each period.

c.  Total sea service is computer-generated and established in MCTFS Career Sea History record (D963 RMK) as the total sum of all sea duty periods minus the number of days of time lost which occurred during each sea duty period.

d.  Career Sea Duty History record Adjust Flag is resident if a career sea duty history remark has be adjusted in MCTFS (D963 RMK).

e.  Career Sea Duty History record Type Code indicates if DoD component service applicable for career sea pay has been reported. ‘Blank’ value [ ] = USMC or ‘FORCED’ [F] = Generated by TTC 188 (D963 RMK).

f.  Career Sea Duty History record Prior Service Quantity (D963 RMK) indicates the number of days of career sea duty earned for periods of prior service not contained within MCTFS but the Marine has obtained and is displayed on a DD-214 (I.E. Coast Guard or Navy prior sea service or Marine Corps prior service that is not captured in MCTFS because of extended period of broken service).

g.  Career Sea Duty History record Total Sea Service is computer-generated and establishes the sum of all periods of the member’s sea duty (D963 RMK).

h.  Career Sea Pay Factor Rate is computer-generated and is established in MCTFS career sea pay record (D907 RMK) to display percentage rate that is applied to career sea duty amount for pay computation of Combat Leave Tax Exclusion (CLTE) tax adjustment for a one-half day offset.

Section 7

Effective 20011001, Career Sea Pay Premium (CSPP) is payable to pay grade E-5 through E-9 with more than 36 consecutive months but less than 8 years of sea duty.  At over eight years, pay grades E-5 through E-9 will receive CSP regardless of consecutive months of sea duty.  Total sea service governs the rate of entitlement to career sea pay per the DOD 7000.14-R Financial Management Regulation, Volume 7A, Chapter 18.  The processing of unit diary entries that start, stop, add, delete or change sea time periods automatically adjust total net sea time.

a.  Use the following transaction to start career sea pay upon assignment to sea duty:

TTC 139 001 [A] START CARSEA DU [B] |

[A] DOA (Date of Action)

• [B] TYPE VESSELNAME (Vessel Type/Name)

Note:  If Vessel Type/Name is not located on drop-down menu within UDMIPS the Admin/IPAC should send a Problem Identification Report (PIR) to MISSA, via their MISSO, notifying that the required vessel name is not resident within UDMIPS/On-line Diary.  MISSA will in turn notify RFF-KCI.  RFF-KCI will submit an update to the MCTFS Table ‘TD’ to add the Vessel Type/Name.  Once this update is in place the UDMIPS user will then see that the new vessel is available within the dropdown selection.

(1)  Prompt [A] is the date the member reported onboard the vessel, Effective Date of embarkation on Marines Temporary Additional Duty onboard the vessel, or Effective Date the vessel is at sea or a port 50 miles away from homeport.  For all CSP transactions with effective date of 31st day of the month, the 31st will display on the 907 RMK, even though pay entitlement FROM DATE starts on the 1st day of the next month.

b.  Use the following statement to stop career sea duty upon termination of sea duty.  (Note: If member is in receipt of Career Sea Pay Premium (CSPP), when TTC 173 000 is reported, CSPP will also be terminated).

TTC 173 000 [A] STOP CARSEA DU |
- [A] DOA (Date of Action)

(1) Prompt [A] is the date the member detached from the vessel, Effective Date of debarkation for Marines Temporary Additional Duty onboard the vessel, or Effective Date the vessel returns to homeport.

Section 8

The DOD 7000.14-R Financial Management Regulation, Volume 7A, Chapter 18, establishes the criteria for entitlement to career sea pay.  Unit diary entries reporting the career sea pay entitlement vary, depending on the length of the sea duty assignment.

a.  Career Sea duty must be reported for all periods of sea duty performed for all Active Duty Marines.  If a Marine becomes entitled to career sea duty pay after the START/CHANGE CAREER SEA DUTY (TTC 139) entry has been reported, or during a period of the CRED CARSEA DU entry, career sea pay will automatically start.  (I.E. If a Marines rates $0.00 for Career Sea Pay entitlement the $0.00 rate of pay will not reflect on 907 RMK, but Career Sea Pay History will reflect on 963 RMK.  When the Marine is promoted or subsequently becomes entitled to sea pay for a monetary amount greater than $0.00, a 907 RMK will be established within MCTFS).

b.  Use the following transaction to report periods of sea duty (not previously reported via Start (TTC 139) and Stop (TTC 173) upon completion of the sea duty assignment, or to credit or adjust period to period 90 days or less sea duty:

TTC 147 000 [A] CRED CARSEA DU [B] TO [C] [D] |
- [A] DOA (Date of Action)
- [B] DATE (From Date)
- [C] DATE (To Date)
- [D] TYPE VESSELNAME (Vessel

Type/Name) Drop-Down selection

(1) Prompt [B] is the date the member reported onboard the vessel, Effective Date of embarkation on Marines Temporary Additional Duty onboard the vessel, or Effective Date the vessel is at sea or a port 50 miles away from homeport.  Note: For all CSP transactions with effective date of 31st day of the month, the 31st will display on the RMK, even though pay entitlement FROM DATE starts on the 1st day of the next month.  (I.E. If Prompt [B] date is equal 20190131 the pay entitlement will start on 20190201).

(2) Prompt [C] is the date the member detached from the vessel, Effective Date of debarkation for Marines Temporary Additional Duty onboard the vessel, or Effective Date the vessel returns to homeport.

Note:  Career Sea Pay is paid and treated as a monthly (30 day) entitlement.  I.E. When TTC 147 000 is reported if the period encompasses the months of February and March, upon calculating days of CARSEA DU, MCTFS will treat the month of February as a 30 day entitlement/month. Example:  If SSgt John Doe rates CARSEA DU from 20190226 to 20190326 (29 days), MCTFS will treat the period as 31 days for pay purposes.  February is paid as 30 days in this case, giving the Marine 5 days for February, plus the 26 days for March, for a total of 31 days.

c.  For sea duty assignments of 1 day, the date of embarkation and debarkation will be the same.  The START/CHAN CARSEA DU (TTC 139) and STOP CARSEA DU (TTC 173) unit diary entries will be reported for sea duty periods of 31 days or more and when sea duty is interrupted by Temporary Additional Duty/TDY or hospitalization ashore.  Accumulation of sea duty time continues during the first 30 days a Marine is on Temporary Additional Duty, TDY, or hospitalized ashore, regardless of whether the Marine is entitled to Career Sea Pay.  Career Sea Pay, if entitlement exists, also continues during the first 30 days in such status (See the DOD 7000.14-R Financial Management Regulation, Volume 7A, Chapter 18). Additionally, transfer within the same MCC from one vessel to another must be reported by START/CHAN CARSEA DU (TTC 139) and STOP CARSEA DU (TTC 173) unit diary entries to update the vessel name in MCTFS history record.  When transferring within MCC from one vessel to another vessel, report STOP CARSEA DU (TTC 173) for the last day on the previous vessel, followed by START/CHAN CARSEA DU (TTC 139) on the date of join aboard the new vessel.

e.  To debit a specific period to period of career sea duty (vice DEL AS ERR the entire period of sea duty), use the following transaction to report the period of adjustment (day for day checkage of CSP of 365 days or less):

TTC 147 001 [A] CHEK CSP [B] TO [C] [D]
- [A] DOA (Date of Action)
- [B] DATE (From Date)
- [C] DATE (To Date)
- [D] TYPE VESSELNAME (Vessel

Type/Name) Drop-Down selection

Note:   The Vessel Type/Name must be same as established in history (as contained on the D963 RMK).

EXAMPLE:  Member Separated 20190120.  D907 and D963 RMK’s exist with FROM DATE 20180801 TO DATE 20190119 on USS GREENBAY

The unit intends to report a debit adjustment of Career Sea Pay from 20181120-20181231 for time not served onboard ship.

Section 9

For Marines with broken service who have returned to Active Duty with prior sea duty credit as reflected on their DD-214, but this time from their DD-214 is no longer resident within MCTFS on the D907, D948, or D963 RMK’s, use the following transactions (Note: TTC 188 restricted to RUC 548XX reporting):

a.  For Marine Corps sea time period(s):

TTC 188 000 CARSEA DU YR

YY {A] MO MM [B] DA DD [C|

• [A] YEARS (Number of Years)
• [B] MONTHS (Number of Months)
• [C] DAYS (Number of Days) (1) Prompts [A], [B], and [C] are accumulated sea service as reflected on prior service DD-214.

b.  For credit of all other DOD Service Component Sea Duty as reflected on the DD-214 (I.E. Coast Guard or Navy):

TTC 188 001 CREDIT CARSEA

DU YR YY [A] MO MM [B] DA DD [C]

• [A] YEARS (Number of Years of Other Service)

(1) Prompts [A], [B], and [C] are accumulated sea service as reflected on the DD-214 (I.E. Coast Guard or Navy):

Section 10

The processing of unit diary statements reporting UA and time lost will automatically suspend career sea pay and the accumulation of sea duty time for the period involved in MCTFS history and pay records.

Section 11

Below are examples of 907 Remarks reflecting Combat Zone Tax exclusion display:

(1) Marine takes one day of leave (April 1), has .05 days of accrued combat leave remaining, is NOT in combat zone in April and is assigned onboard ship.  The open 907 Remark will stop 3/31 (with rate factor of 1). There will be two 907 remarks for 4/01.  In the example provided below 907 RMK SEQ #2 represents the half day (.05) of CSP with Combat Leave tax code, 907 RMK SEQ #3 represents the half day (.05) that is processed with tax code 1, and 907 RMK SEQ #4 represents CSP being reestablished when the member returns from leave on April 2.
