Subsea 7 Mezzanine Decks

43te (per assembly) of Universal Column, European Steel Beam Sections, PFC and Profiled Plates supplied
IPE 500 sections purchased and supplied from Continent to meet client’s specifications
Mezzanine Deck was floored out using GRP grating panels – approx. 460m² (per deck)

Dales used their workshop in Grangemouth due to Aberdeen’s high workload at time
Mezzanine was designed to be fabricated in 6 individual modules
Total dimensions for completed mezzanine deck was 25.8m long x 18.2m wide
Fabrication of the first vessel was completed and continued with second build
Workshop was capable of taking 2 modules at a time with rotation outside when completed and NDT inspected
All welding connections were full penetration with 50% UT Inspection required
Full NDT inspection with load test of lift points

Dale’s scope included the preparation and painting of the modules prior delivery to vessel
Using our highly skilled ship painters along with qualified paint inspector we paint-ed all twelve modules onsite
Steel was purchased pre-blasted and shop primed prior to fabrication. Minimal damage was done during fabrication to the coating
Mechanically cleaned all weld areas, scars and damaged areas and proceeded with priming. Strip coated all welds and proceeded to paint to manufactures and clients specification
All onsite connections were masked off and left primed to save preparation time onsite

Utilising three arctic trucks with wide load notification and police escort we shipped the first mezzanine deck assembly to our Leith base for mobilisation.
The second mezzanine deck had the same requirements but was sent to our Aber-deen facility to be mobilised during dry docking.
