An offshore wind operator needed a 34 m aluminium CTV to meet demanding motion criteria for turbine transfer while staying inside a 34.0 m length cap set by berth licensing.
Hull form developed against the operability motion criteria, not just resistance — seakeeping drove the form
Scantlings designed to the class rules for aluminium high-speed craft with the governing check identified per member
Structural drawings prepared to the society's submission conventions, which is where most first submissions fail
Pre-submission review with the class surveyor before formal issue
Resistance and propulsion prediction validated against a sister vessel's trial data
A 7-storey 1970s office block had to stay occupied through a seismic retrofit. The original drawings were incomplete, concrete strength varied by 40% between cores, and the client could not vacate more than one floor at a time.
A die-cast aluminium pump housing was 22% over its mass target but the tool was already cut. A new tool would have cost the programme five months.
A 42 MWp plant's provisional connection offer carried a reactive capability condition the originally specified inverters could not meet across the full voltage range. The issue surfaced three weeks before financial close.
