1.0 SCOPE

The National Oceanic and Atmospheric Administration (NOAA) operates a fleet of research vessels that supports research and mapping for the National Fisheries Service, National Ocean Service, Office of Atmospheric Research and the National Weather Service, as well as provides support to other Federal agencies. These research missions are time sensitive and therefore the data must be collected at specific times during the sailing season to be meaningful. At the end of each sailing season the vessels enter a repair period (drydock or dockside) to address repairs that have been previously identified, perform upgrades to mission systems or ship systems that either extend the life of the ship or provide new data collection capabilities or for safer operations of ships systems as well as address any emergent work that would adversely affect the ships ability to safely perform its mission on schedule, while meeting all regulatory body requirements (American Bureau of Shipping and United States Coast Guard) and all habitability requirements, including any that may be required as a result of contracts for personnel to augment ship staff.

The work items in the repair specification are identified well in advance of the performance period in order meet the contracting lead times. Additional work items (emergent work) may arise during the period between the work package submittal, contract award, or even prior to the start of or during the contract performance period. In accordance with Commerce Acquisition Regulation (CAR) clause 1352.271-72, the Contracting Officer may order additional changes during the contract period of performance to address any additional work items identified as necessary to ensure the intent of the drydock or dockside repair contract is met; that is, that the vessel shall be able to safely perform its mission, that it will meet all habitability requirements and regulatory body requirements, and that such repairs will be timely performed to ensure to the maximum extent practicable that the ship's schedule is not adversely impacted.1.1 This specification contains the requirements for Fiscal Year 2018 (FY18) dockside repairs and modifications to NOAA Ship Okeanos Explorer.

3.7.3.2 Fire Detection Panel Troubleshooting

3.7.3.2.1 Three (3) new zones were added to the fire detection system in 2014. Over the last several months, the system has experienced multiple trouble alarms that, when silenced go away, then come back. The ship has attempted to troubleshoot and repair the system with the assistance of a tech rep remote from the ship and has had some success, but the issue has not been fully resolved. The situation as it stands now is that the ship has jumped out the two modules that control the 3 new zones.

Therefore, effectively, the 3 new zones are not being monitored.

That seems to be the only way to eliminate the nuisance trouble alarms.

3.7.3.2.2 Provide the services of an experienced, authorized

Pyrotronics System 3TM technical representative (tech rep) to troubleshoot and repair the fire detection system.

3.7.3.2.3 For bidding purposes, assume the tech rep will be

onboard ship, performing troubleshooting and repair activities for two full days (in addition to travel to/from city of origin).

3.7.3.2.4 If additional time or materials are required, submit a condition report to the Contracting Officer’s Representative (COR). Any such additional work must be approved in advance by the Contracting Officer.
