Blast-It-All Ship Blocks and Hull Sections
Ship blocks and hull sections need blast areas planned around oversized steel, welded seams, stiffeners and crane or transporter movement. Double D Mechanical installs, relocates and services blast rooms, abrasive blast booths, exhaust ductwork, make-up air and related utility connections for marine fabrication environments.

Hull Section Fit And Handling
A Blast-It-All blast room for ship blocks must be laid out around the largest section that will enter the enclosure, plus the rigging path that gets it there. Door width, ceiling height, floor loading, crane clearance and transporter approach all affect whether the room works in daily production. Access also has to account for weld seams, internal frames and areas that may require operators to work from lifts or platforms.
Blast Room Air And Media Recovery
Large marine parts create heavy surface preparation demand, so the blast room layout should keep abrasive, dust collection, floor recovery and operator movement coordinated. Exhaust pickup, inlet air, media return points and hose routing should be reviewed together so the room does not fight the plant airflow or create avoidable cleanup around adjacent work areas.
- Confirm the largest block dimensions and expected orientation before layout work.
- Identify crane hooks, transporter paths and floor pits near the proposed room.
- Review dust collector location, discharge routing and service clearance early.
Coating Flow After Surface Prep
Hull sections often move from blast cleaning into coating, touch-up or staging areas. The surrounding floor plan should separate dirty and clean traffic, keep forklift lanes clear and leave room for masking, inspection and coating carts. When the blast room is part of a larger finishing sequence, booth exhaust, make-up air and building pressure need to be considered as one system.
Site Visit Details To Prepare
Before a site visit, it helps to gather room drawings, structural bay dimensions, utility locations and the way ship sections currently move through the plant. Double D Mechanical can use that information to evaluate equipment placement, duct routes, electrical and air needs, fire protection interfaces and maintenance access for fans, filters, reclaim components and doors.
Frequently asked questions
What should be measured before planning a blast room for ship blocks?
Measure the largest hull section, expected transport orientation, crane hook height, door approach, floor elevation changes and the clearance needed for operators, lifts and hoses.
Why does make-up air matter for large blast rooms?
Exhaust air has to be replaced in a controlled way. Poor replacement air can affect room pressure, dust containment, adjacent coating areas and comfort for people working nearby.
Can an existing blast room be relocated for marine fabrication work?
Relocation can be evaluated if the room dimensions, panels, collector, reclaim equipment, electrical service and ductwork can fit the new production flow and building constraints.
What trades usually need coordination around this equipment?
Structural, electrical, fire protection, compressed air, concrete, rigging and mechanical trades often need sequencing so the room, collector, ductwork and utilities come together cleanly.
