Narrative: This was the second leg on the first day of a domestic two day that I was assigned in R.O. (Relief Officer). There are several items we noted that need to be addressed for safely handling this type aircraft at ZZZ.We landed on runway XX after sunset and taxied via [route] to gate. There are numerous notes and cautions on the ZZZ 10-9 page regarding taxiway restrictions for a large aircraft's wingspan; all of which applied to us. We briefed each note; along with our expected taxi route after landing and were well prepared for the instructions issued by Ground. There are notes in the ZZZ company pages that mention taxi lines in the ramp area that apply to the 757 only as opposed to narrow body. No mention of any other widebody restrictions. Thankfully this was only slightly confusing and did not apply to our gate area. As we approached taxiway X; we were cleared in the ramp via XY. The ramp is well lit and we clearly saw the lead in lines to the gate. What we did not notice was how close the taxiway edge lights on the east side of X are to the taxiway centerline. There is no depiction anywhere of the ramp taxi lines of various colors and their proximity to the movement area. What we realized the next morning was where we turned in at XY put our engine nacelles uncomfortably close to those aforementioned edge lights.The next morning; we were unsure; based on all the ZZZ wingspan restrictions; how we would be routed for takeoff; so we queried Clearance about their intentions. The controller was very helpful and had a clear understanding of the limitations imposed by our wingspan. When it came time to pushback our clearance from Ramp was to 'pushback [color] line for a [taxiway] exit.' Our tug driver told us he could not push us to remain on the ramp; because our wing would overlap X taxiway. There are no notes or depictions of a ramp taxi line or color (other than [a couple] spots); so we were a little unsure what he meant. We coordinated with Ramp and then Ground to pushback facing north on taxiway X. We did not enter the movement area until cleared by Ground. The tug driver was extremely professional; taking no risks with us. During the push we saw the north/south blue taxi line on the east side of the ramp he had spoken of and we both agreed with his assessment that our right wing would have impeded X. We had some confusion about the Ground frequency; which delayed us several minutes; but was eventually cleared up.Our taxi to takeoff was uneventful; although the stop signs and hold lines for the east-west vehicle crossing midway on [one of them] are too close to the taxiway to provide clearance for our wingspan. We had to stop for a truck to back up away from us.Takeoff was uneventful; however; the [company] FMC database does not include the EO (Engine Out) SIDS. We therefore we put [the SID] in the fix page to help in case of need.Suggestions: The company and ZZZ airport need to address these issues if this aircraft type is going to be safely serving ZZZ in the future.1) Add the EO SIDS to the FMC database2) Have Company evaluate the 787 operations at ZZZ; especially the possibility of the wings extending over the movement line when on the ramp taxi lines and the proximity of the taxiway edge lights on X.3) Add depictions of the ramp taxi lines. Currently there are none. Ramp issues clearances to ramp lines based on color and those of us who are unfamiliar are left confused. Not good.4) Clear up the ZZZ [company] page notes regarding ramp restrictions by A/C (aircraft) type. As currently written; they are confusing for any pilot not operating a 757 or a narrowbody.5) The Standard Taxi instructions on ZZZ pages have the departure and arrival instructions joined together in the same boxes. The paragraphs should start in bold font to highlight the different procedures. We missed the 'Arrival aircraft...' procedures during our approach briefing. Thankfully they did not apply to us for this flight.




Synopsis: B787 flight crew reported company and airport procedures/manuals require updating for new widebody aircraft.
