Phobos- Main Engineering
An attempt to figure out the engineering section of Kevin Riley’s beautiful model of the refit Loknar Class- USS Phobos.
Initially, I had to decide exactly where I wanted a major section that would be referred to as “Main Engineering.” The ship’s catamaran like split aft of the primary hull results in what are essentially two secondary hulls. Although a single engineering compartment forward of this split feeding both warp nacelles would have been practical, the central placement of the shuttle bay managed to interfere with this. The presence of an interconnecting pylon between each of the catamarans, as well as independent impulse engines at their aft ends, also informed the decision making process. I decided one catamaran, the port side, would house a main engineering section responsible for monitoring all ship’s propulsion functions while the starboard side could house a dedicated auxiliary section mirroring the port. These two sections would be directly linked however, and provide an overall balanced propulsion for the entire ship.
First, The Gallery
After feeling more comfortable rendering with Global Illumination.
Upper level where the intermix shaft feeds into the impulse engine. The portion of the shaft which feeds the warp nacelle is visible breaking above deck to the left. Everything is illuminated by the elements within the image.
An early view from inside what would become the maintenance tunnel/computer monitor area (obviously before I placed the monitors within, since one is visible on the other side of the grating). It does reveal a nice, though slightly obstructed view of the post-intermix plasma shaft winding upwards on its route to feed the port warp nacelle, here at the base of the nacelle support pylon.

From here, the warp intermix shaft is visible below on the main level. Also, you can finally see the shape of the large toroid structure that surrounds the impulse deflection crystal. Design elements are finally settling into place.
I always thought it looked right out of the The Motion Picture era though, so I thought I would include it here. This shaft’s actual purpose isn’t entirely clear to me yet, but considering the two distinct catamarans of the engineering hull, it makes for an excellent juncture shaft for interacting with the opposite side of the ship, since both sides have warp nacelles which must be fueled. This too would make it critical as a means of diverting auxiliary power to the mirror side of the ship. It’s placement is purposefully set up to run down, toward, and past the under-slung torpedo pod as well, so it’s probably the main feed of antimatter for arming photon torpedoes, as well as.
And, Behind the Scenes.
I began blocking with the major outboard features that I thought would interact with this area and use them as anchors and barriers to a plausible interior structure.
These features include:
The impulse deflection crystal array atop of the engineering section.
The impulse engine’s main exhaust vents aft of the ship.
The large tanks mounted on the inner walls of the engineering section’s catamarans. I reckoned they were some sort of fuel tanks possibly containing deuterium slush. In the Trek Universe, deuterium is thought to be the primary matter component of the matter/anti-matter reaction warp engines. Some of that fuel source is siphoned off, as it is also used in the impulse engines.
The engine nacelle pylons are also important to the placement of the main intermix shaft, as are a number of external hatches and view ports. Some “hatches” are curious trapezoidal plates located at various places along the flat inner surfaces of the catamarans. I thought they would make for interesting access to the larger, modular, engine components that could be replaced when necessary from the outside but accessed for normal maintenance from inside the engineering room. Unfortunately a few of the ship’s external view ports don’t fit with any reasonable deck layout that I could come up with, so I decided to go with artistic license on that one.
