IST (Kresco) Ship Block Blast Room Installation
Ship blocks and hull sections bring large plates, stiffeners, curved surfaces and weld details into surface preparation areas before protective coating. Double D Mechanical installs, relocates and services blast rooms, media reclaim systems, booth exhaust, make-up air and utility connections used around IST (Kresco) equipment for marine fabrication and repair work.

Block Geometry And Access
Marine sections can be tall, curved and irregular, with ladders, stiffeners and pockets that limit operator reach. Room layout should provide clearance for handling equipment, temporary platforms and the full part envelope without blocking doors, lights or service aisles.
Surface Prep In Welded Compartments
Hull sections and blocks often require attention to weld seams, edges, corners and recessed areas. Blast room planning should consider how operators move around both sides of a section and how abrasive will be recovered from beneath supports and fixtures.
Ventilation For Large Fabrications
Large marine parts can interrupt airflow if exhaust pickup and replacement air are poorly placed. Collector location, duct routing, inlet placement and make-up air should be reviewed so visibility remains workable and dust stays contained inside the preparation area.
Installation Around Yard Operations
A site visit should include crane coverage, bay dimensions, floor conditions, compressed air, electrical service, exhaust discharge path and adjacent coating areas. Maintenance access to the dust collector, reclaim system, lighting and controls should remain open after fixtures are added.
Frequently asked questions
What ship block information helps with blast room planning?
Maximum section dimensions, lifting method, support stands, access platform needs, expected coating sequence and the route to paint areas are all useful.
Why is airflow planning difficult with hull sections?
Large curved or boxed structures can block or redirect air, which affects dust capture, visibility and the way spent media settles around the part.
Can reclaim equipment handle large marine sections?
Reclaim equipment can be configured around the expected work zone, but the floor layout and cleanup access need to match where abrasive actually falls.
What should stay accessible after installation?
Collector doors, filters, reclaim drives, separator components, lighting, controls, compressed air drops and personnel doors should remain reachable.
How should blasting connect to coating work?
The flow should move prepared steel toward cleaning, stripe coating, masking and paint areas while keeping blast dust away from coating operations.
