1 Share of the derrickhand role’s weighted skill requirement already met by the roustabout profile. Required skills count in full, supplementary skills at 0.35. Directional: the figure for the reverse move differs. 2 Combines what is missing with how specialised it is, so a gap of general skills scores easier than the same number of narrow ones.

Table 2

Table 2 · What you already bring

Of the 4 skills that carry over, these are the ones fewest other occupations ask for. A derrickhand role needs them, and most people applying for one will not have them already. This is the part of a roustabout background worth leading with.

Skill the target role also needs Area

already held work in drilling teams communication, collaboration and creativity
already held connect equipment to wellheads working with machinery and specialised equipment
already held inspect pipelines constructing
already held mechanics engineering, manufacturing and construction

All 4 carried skills, including the 2 the derrickhand role treats as required.

Table 3

Table 3 · What you would need to learn

The 14 missing skills fall into 8 areas of the ESCO skill hierarchy, numbered below in the order worth working in: the areas carrying the most required skills come first, and inside each one the required skills sit above the supplementary ones.

3 gaps that are knowledge rather than practice

Knowledge gaps usually close through study. Practical skill gaps usually need something you can point at.

Note

How this record was compiled

Both occupations are taken from ESCO, which lists the skills and knowledge each occupation is expected to have and marks every one required or optional. Nothing here is a prediction about hiring, and nothing here knows that a particular employer wants a particular certificate. Treat Table 3 as a starting point for your own research rather than a syllabus. The full method states what these figures can and cannot tell you.
