Sea-Fastening Steelwork
A sea-fastening steelwork programme associated with the offshore gas development, involving 100+ tonnes of fabricated steel delivered with 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 affiliated group companies. It is presented as group experience and does not represent a direct contract held by Costro Projects Management L.L.C.. 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
Fabrication of sea-fastening steelwork and supports for heavy transport, totalling 100+ tonnes.
Grillage & Supports
Fabrication of grillage and transport support steel to issued drawings.
Procurement
Procurement of steel, consumables and certified materials for the fabrication scope.
Quality, ITP & NDT
