KETCHIKAN, AK

MV LeConte

2024

The MV LeConte is an Alaska Marine Highway System “Shuttle Ferry.”  It is named after the LeConte Glacier, located in SE Alaska near the coastal community of Petersburg.  The MV LeConte is 235’ long; has a Beam of 57’; and the Draft is 14.5’ at gross weight.  It is designed to carry up to 225 passengers, and the vehicle deck will the equivalent of 33 twenty-foot vehicles.

​

In the late fall of 2023 Graham Industrial was approached by Vigor Alaska Ketchikan and offered an opportunity to assist in the 2024 overhaul of this vessel.  

​

Our scope includes the removal and replacement of Underwater Hull coatings; Capastic zone coatings replacement; and interior voids renovation.

VALDEZ, AK

Petrostar Refinery Crude Heater Coatings Renovation

Graham Industrial has been providing Industrial Coatings Services to ASRC / Petrostar since 1999.  In 2023 we were the successful offeror on the Valdez “PSVR Heater Project.  This project provided some unique problems to solve: 1) It was 120’ tall to the top of the stacks and the project contained 14,000 square feet of complex surface area; 2) Only the stacks would be Abrasive Blasted and Painted with the heater shut down.  The rest of the project had to be performed while the heater cabinet was running and hot; 3) The heater is located in a densely-packed crude processing unit with a lot of sensitive equipment surrounding it. We had to find a way to control fugitive blast media dust during our abrasive blasting process and could not contaminate the project site with blast media; and 4) the weather in Valdez is rarely ideal for external surface preparation and coatings. 

 

We chose to use a dustless blasting process called “vapor blasting” to remove the old coating on the PSVR heater and prepare the steel substrate to receive new coatings.  The blasting machine is a high-capacity Axxiom “Amphi Blast” 4-nozzle bulk blaster.   The Amphi Blast system suppresses the dust created during abrasive blasting by injecting a highly-atomized water stream into the blast media stream.  This solved the problem of abrasive blasting in and around other equipment.  The damped blast media is heavy and falls vertically to the ground.  

​

The coating system specified for the project is a next generation single-component inert multipolymeric matrix capable of withstanding surface temperatures up to 1200F.  Part of the reason we selected this product is that it can be applied on hot surfaces up to 500F.  This solved our problem of applying coating to the heater cabinet while it was operating and hot.

Graham Industrial has had the distinct honor to be a subcontractor to Vigor Works on the multi-year new construction of Missile Field #4 at Fort Greely, AK.  

Fort Greely, AK is one of two US locations which hosts the Ground-Based Midcourse Missile Defense Program.  Ground-Based Midcourse Defense (GMD) is the United States' anti-ballistic missile system for intercepting incoming warheads in space, during the midcourse phase of ballistic trajectory flight. It is a major component of the American missile defense strategy to counter ballistic missiles, including intercontinental ballistic missiles (ICBMs) carrying nuclear, chemical, biological or conventional warheads. (Wikipedia, 11 January 2024)

Our Scope of Work on GMD MF-4 has been multi-faceted.  In addition to protective coatings install, we’ve also installed thousands of gallons of Urethane Spray Foam Insulation, Polyurea Waterproofing Membrane, and have provided Scaffold Services and Environmental Controls. 

We are proud to have worked more than 60,000 hours on the project without a lost-time injury.  We exceeded quality-control and quality-reporting requirements and finished the project on time, on budget, and  with accolades. 

HEALY, AK

GVEA Healy AK Power Plant Waterproof Metal Roof

One of Graham Industrial’s specialties is finding solutions to remediate existing infrastructure to preserve or restore useful service life.  The Golden Valley Power Plant in Healy had a serious problem with leaking roofs.  The harsh climate and powerful wind storms in healy lead to significant damage to the engineered metal roof system.  

After receiving an exorbitant contractor quote to replace the roof on this industrial structure, GVEA called us to inquire about our waterproofing services.  After consideration, we recommended PPG / GACO’s “GacoFlex” line of roof silicone membranes as an overlay solution.

 

GACO’s silicone products have proven to be a resilient and affordable solution for worn, damaged, and leaking metal roofs.  The silicone overlay system is a fraction of the cost of replacing a metal roof system.  Furthermore, Graham has successfully installed silicone systems over other commercial roof substrates such as EPDM, EPO, and Hot Tar.  

​

As with all waterproofing, coating, and  lining systems, proper surface preparation is the key to a long service life.  Approximately 85% of early coating failures are directly tied to improper surface preparation.  

On this project, we carefully cleaned every square foot of roof area with a hot-water etching wash combined with thorough abrading with Maroon Scotchbrite Pads.  Then the roof was primed with PPG Amerlock 100% solids epoxy.  The next step is to individually seal screw heads, lap seams, and holes / punctures with GACO SF2000 and embedded mesh.

​

After surface preparation and sealing, the roof is overlaid with 24.0 - 30.0 mils of GACO S20 Silicone membrane.  Two years later and our roof has produced ZERO leaks and ZERO adhesion failures.  It holds up to high wind, ice, snow, and lots of rain!

2020

Graham Industrial is one of the largest metallization contractors in the State of Alaska.  In simplest terms, “Metallizing” is the process of temporarily liquifying pure zinc or zinc-aluminum alloy and depositing the alloy onto a steel surface by spray-application.  

In 2020 we were part of the Granite Construction Team that rehabilitated the Rabbit Creek Pedestrian Bridge over the Seward Highway.  This project presented a number of unique challenges: 1) We worked during temporary lane closures at night; 2) We worked at elevation 26’ above the active roadway; 3) We had to fully mobilize at the beginning of the 12hr shift, and be completely demobilized for lane-reopening at the end of the shift;  4) We had to be able to move quickly with all equipment being mobile and much of it elevated, and 5) The abrasive blasting process was performed on Lead-Based Paint required compliance with all OSHA and EPA regulations, means, and methods.  100% containment with negative-exposure systems is not easy when on the move. 

We modified a military-grade aircraft cargo truck for this project.  We constructed a double-deck system in which the elevated cargo box housed our equipment, and on top of the box was a scalable work platform / containment system used for the abrasive blasting, metallizing, and sealing processes.
