Limited progress was made today. I worked on getting network access in the test cell. This involves contacting ISS with the room RJ port number and the test computer's unique identifier (physical address). Both of these pieces of information were forwarded to ISS but there was no indication of lead time on the request.
RJ port : CR2-050
Physical Address : 00-40-63-E4-EF-20
I met with William Kelly, head of facilities which resulted in some new administrative issues that need to be dealt with before the engine can be commissioned. William highlighted that a risk assessment needed to be done on the project before any further work could be completed.
William mentioned in particular:
Carbon Monoxide - He mentioned that they have had problems with this in the past.
Diesel handling - He mentioned the risks associated with dermatitis induced by diesel skin contact.
Mitigating these risks is not going to be an issue. A maximum of 5 litres of diesel will be stored in the engine header tank at any given time and the tank can be filled using gloves with suitable equipment (jerry can with nozzle/hose). Carbon monoxide levels will be negligible at most as the engine utilizes a diesel burner which burns the fuel almost to completion (Nicholas Farra's thesis estimates 99.99%) and any exhaust will be extracted using the exhaust extraction system. As a final layer of protection the cell has multiple toxic gas detectors in case of any build up of CO.
It is worth noting that the test cell was specifically designed for running diesel engines.
A detailed risk assessment will be undertaken at 12pm on Monday with myself, Rory Monaghan and Pat Donnellan (engineering building safety officer) and any recommendation will be acted on.
