Sea-Fastening Steelwork
A sea-fastening steelwork programme associated with the offshore gas development, involving 100+ tonnes of fabricated steel delivered with our partner a group logistics partner. This is presented as affiliated group experience, see the note below for how Costro’s role is defined.
Project Facts
This offshore scope reflects collective, affiliated group management experience delivered with our partners through our sister company, Rais Naser. It is presented as group experience and does not represent a direct contract held by Costro Projects Management LLC. Within offshore temporary steelwork, Costro’s role is limited to fabrication, procurement and quality only.
Delivered Across Multiple Disciplines
Within this group programme, the work attributable to Costro’s disciplines centred on fabrication, procurement and quality.
Sea-Fastening Fabrication
