Crane Certification Study Built Around Sitka's Island Jobs

Lessons from the Blue Lake job

The Blue Lake expansion raised an existing concrete arch dam by 83 feet, added a powerhouse with three 5.3 MW turbine-generators and a new intake and tunnel, and kept the old dam and powerhouse running throughout. The Alaska Energy Authority says the work lifted system capacity from 7.5 MW to 16.9 MW and was expected to displace millions of gallons of diesel a year.

For a crane crew, the remarkable detail is access: because the dam sits in a steep, narrow canyon with no way in on one side, everything that crossed it went by crane. Lifts like that depend on careful radius planning, an exact weight for every piece and a signal person who can see what the operator cannot. Those are the same skills tested on rigger and signal exams.

Hatch, the project's engineer, said in 2016 that the expanded plant was helping cover all of the city's power needs. The project is finished, but hydro plants need ongoing maintenance, and turbine, gate and transformer work inside a powerhouse brings its own lifts: tight headroom, overhead hoists working alongside mobile cranes, and parts with odd centers of gravity.

Two waterfronts, two purposes

At Halibut Point, the Sitka Sound Cruise Terminal finished a dock expansion in 2021 that lets two large ships tie up together, carrying up to roughly 4,300 passengers at once. It is privately held, with Halibut Point Marine Services as majority owner and minority stakes from Royal Caribbean Group and Ceres Terminals.

South of town, the Gary Paxton Industrial Park on the old pulp mill site got a city-built deep-water dock in 2017, put into service in 2018 mainly for fishing vessels and tenders up to about 150 feet. Industrial park work leans toward marine service, seafood and freight rather than passengers, and it calls for boom trucks, forklifts with jibs and the occasional mobile crane.

Planning lifts in Southeast weather

• Heavy rain makes footing soft; check outrigger cribbing on fill and gravel lots.
• Wind off Sitka Sound can arrive quickly. Agree on a stop-work gust number before you rig.
• Tide moves vessels up and down against docks, so recheck radius and boom angle on longer picks.
• Barge deliveries mean equipment may arrive unfamiliar; read the load chart for the exact configuration, every time.

Testing from an island

Practical exams require a machine and an examiner, so Sitka candidates generally fly to Juneau, Anchorage or the Lower 48 when the certifying body has a session. Written exams can often be taken by online proctoring, which may spare one trip. Get the studying done first so travel is planned around a single practical date.
