Sample projectSample projectMarine & Defence — common questions
Can you work inside a drydock or refit schedule?
That is where most of our marine work happens. We plan surveys around yard shifts and hot work, deliver field results the same day, and have never been the critical path on a docking.
Do you work on naval and security-controlled projects?
Yes — we have measured submarines and naval vessels under yard security regimes, and our staff hold the clearances the work requires. Specifics are discussed directly.
What marine tolerances can you certify?
Shaft line surveys are routinely delivered to ±0.05 mm over full shaft lengths, with bearing reactions computed by a P.Eng. The report states achieved uncertainty, not just pass/fail.
