## Description
The Authority has a requirement for Services, calibration, repair and maintenance of OTTO Fuel Monitor (OFM), including spares provision. The OTTO Fuel Monitor (OFM) Mk2 is a hand held instrument designed to monitor for the presence of OTTO vapour in Cat C environments, in the event of fuel-leaks from Torpedoes. OFMs are used to monitor the atmosphere where Spearfish Torpedoes are stored and processed, this includes DM Beith and on board submarines. 
OTTO fuel is toxic and relatively small concentrations can cause respiratory problems, headaches and nausea. Continued use of the OFMs is required to ensure the health and safety of personnel operating/maintaining the Spearfish Torpedo, and to ensure the continued safe storage and processing of Spearfish torpedoes. 
The OFMs require calibration after 6 months of use. The current holding of OFMs and Desensitised Otto Fuel Monitors (DOFMs) is 110 units. 
The contract will be for 5-years to commence quarter 1/quarter 2 2022 (subject to change), with one 2 year option. The Contractor is required to conduct an initial survey and calibrate and/or repair the in-service OFMs and DOFMs as and when they are returned from Defence Munitions (DM) Beith. There will also be a requirement to complete project management activities and management and delivery of spares as required. An additional tasking element shall provide the Authority with a means to request project activity outside of the core element, at additional cost.
Should this requirement proceed, a Contract Notice will be published in due course with more precise requirements and interested parties will be invited to complete an online Pre-Qualification Questionnaire, which will be measured against selected criteria in terms of commercial and technical requirements. Additional information: The contract will be for 5-years to commence quarter 1/quarter 2 2022 (subject to change) until 28/02/2027, with one 2 year option.
