E & P contract Management

A: A tangential inlet isn't decoration; it's bound to droplet breakup, residence time, and carryover. Option B sounds reasonable if you're thinking pressure vessel code only, but the contract ties performance to datasheet parameters, not shell strength. Option C mixes governance with technical cause — MOC doesn't transfer vendor non-compliance risk. Option D fails because P&IDs rarely define inlet geometry; they define connectivity and safeguards, not hydrodynamics.

A: Shared standards with a single supply party reduce mismatch claims. Option A splits responsibility right at the leak path — classic claim trigger. Option C feels protective but forces the contractor to accept geometry they didn't control, inviting fit-up disputes. Option D imports a design margin argument; higher class doesn't fix misaligned responsibility and may break skid nozzle ratings.

A: 4,200 bpd is about 27.8 m³/hr. 8.5 divided by that gives just under 0.31 hr, then minutes. Option B forgets the hour-to-minute step. Option C uses total volume, a mistake seen when gas space is ignored. Option D over-corrects by stripping volume without a basis from the datasheet.

A: Internals drive shop labor, welding, and NDT, plus schedule knock-on. Option B ignores that nozzles and supports often move. Option C assumes shell rerating, which isn't implied. Option D confuses performance obligation with physical change cost — auditors won't accept that leap.
