C SPRUCE Check List
11.1 PURPOSE. The Scheduled Preservation Upkeep Coordinated Effort (SPRUCE) program has been established to ensure internal preservation is maintained at the highest possible level throughout the life of the ship. As a result of increased intervals between submarine CNO Maintenance Availabilities, effective SPRUCE upkeeps are of prime importance. SSBN 726 Class submarines are exempt from SPRUCE upkeeps. Under special circumstances, requests for SPRUCE upkeeps on SSBN 726 Class submarines will be considered and shall be conducted in accordance with this chapter.
11.2 SCHEDULING.
a. ISICs shall schedule a SPRUCE at periodicities specified by each TYCOM for operational SSN submarines. The SPRUCE shall contain a 14 day production period which will not be scheduled to commence sooner than two days following an underway period. Per references (a) and (b), underway periods shall not be scheduled within five days of completion of the production period. In summary:
Ship returns to port 0 days
Preparation period 2 days
Production period 14 days
Gas off period 5 days
TOTAL 21 days
b. A SPRUCE shall not be scheduled during other Ship's Force or FMA upkeeps with the exception of the five day gas off period which may be scheduled during a follow-on upkeep. A SPRUCE should not be scheduled within the six month period prior to a SRA. A SPRUCE should not be scheduled within six months before or after a CNO Maintenance Availability because of the industrial activity's preservation programs.
c. The initial base date for scheduling is the official completion date of the ship's last CNO Maintenance Availability.
11.3 RESPONSIBILITIES.
11.3.1 Type Commander.
a. Administer the SPRUCE program.
b. Maintain a file of SPRUCE lessons learned and distribute to ensure that all commands concerned have the latest information available.

b. Coordinate submarine crew training.
c. Monitor the effectiveness of the SPRUCE program.
d. Chair a SPRUCE debrief with Ship's Force and FMA to review the effectiveness of the SPRUCE and generate lessons learned. The results of this meeting will be included in the Ship's SPRUCE completion letter.
11.3.3 Fleet Maintenance Activity.
a. Provide training, tools, consumables, services, and required support personnel.
b. Provide technical guidance consisting of around the clock coverage by a coatings inspector trained to the requirements of reference (c). The coatings inspector will perform all inspections necessary to ensure proper preservation is accomplished and will complete Appendix B of this chapter for each area preserved. All completed forms from Appendix B of this chapter will be submitted to the ship for inclusion into their SPRUCE completion letter.
11.3.4 Submarine Commanding Officer.
a. Ensure preservation is performed by Ship's Force using the procedures contained in references (c) through (e).
b. Ensure Ship's Force personnel are relieved of all requirements other than those necessary to maintain the safety and security of the ship during the SPRUCE.
c. Designate an officer or Chief Petty Officer (CPO) to serve as the SPRUCE Manager.
d. Ensure the ship is divided into preservation zones. Each zone will have an officer or CPO in charge during the SPRUCE. Conduct a thorough preservation inspection of each zone, assisted by an FMA coatings inspector (if possible) at least 90 days prior to the start of the SPRUCE to determine and prioritize the preservation to be accomplished. Appendix C of this chapter shall be reviewed as part of this inspection.
e. Submit completion letter to the TYCOM via the chain of command. This letter shall report results of the SPRUCE, problems encountered, lessons learned, and shall contain completed forms from Appendix C of this chapter.
