Deck Crane
The deck cranes on/off switch and operating indicator lights are located in the Wheelhouse on the Aft control panel. It is located in the Wheelhouse to ensure no one operates the crane without the navigation watch knowning. Operations calls for a member to stay near this switch in communication with the Crane PIC and Safety Officer. From this height the sight lines are an added safety factor for the crane’s operation.

The tank has an External Sight/Temp Gage, Fill Cap/Filter and Vent.
The reservoir’s vent is filled with a material to limit moisture contamination of the hydraulic fluid.
The hydraulic fluid is a vegetable based oil that is environmentally friendly. ISO 46 vegetable base.

22. Deck Crane Remote Controls
There are Two portable Remote Controllers. One has a waist strap
the other has a wedge style mounting bracket for the crane basket.
When mounted in the Basket the control unit can be attached to a cable near the mount. Engineers we will cover these when we get home.
Hetronic-Nova Series.

Note: There are two internal locking devices that lock the crane in place once it is bedded and shut down. It will not shift in adverse conditions.

No Safety Officer! Not paying attention! We got a new winch and cable out of this mishap. Chocka Blocka. The operator has to always be aware of the location of the pulley and Headache ball when you are extending the boom. They're the experts and this still happened.

25. Crane Operations Safety
Crane operations on these vessels has to have a high level of planning and training. Engineers have all seen some time on Aerial Ladder Trucks. Think about this, “Throwing A Ladder” without deploying any outriggers…scary proposition.
So we will be adjusting the operational plans as we go. We will try to get this started from what we are learning up here in Seattle.
From what we have seen so far, the crane is impressive. The boat is very stable while sitting in calm water or along side the dock. Obviously that all changes with any wind/sea conditions other than calm. Surge and or wind/weather conditions will always be a chief consideration. The crane is a great tool, but has limitations based on various external factors.
Lastly, we will be using the crane to deploy the Utility Skiff. This takes some finesse - lots of obstacles - so practice will be the key. Skiff/crane op’s will be covered in the Skiff Powerpoint.

26. Deck Crane Quick Safety Review
When we turn the Hydraulics (HPU) on from the Wheelhouse (remotely), the operator must make sure no personnel are working on the HPU in the aft hold, unless they are made aware that you're starting the equipment. (Phones are located near the HPU)
We do not start the HPU unless we have a plan in place to use it or we are conducting Testing/Maintenance.
ANY Crane operation will first have a Planing/Safety meeting. This meeting will cover Goals, Risks and individual assignments.
Positions will cover: Person in Charge (PIC) (Engineer), Saftey Officer (Captain), Crane Operator (Engineer) Line Tenders (Deckhands) and Look-out/Spotters (Pilot). All positions will have comms.
PPE: The amount of Protective gear will obviously be determined by the tasks at hand. Helmets and Gloves should be the Minimum.
FYI: While climbing the access ladder to the crane platform. Keep your head close to the ladder. Both Fred and I found out why. Bad!

27. Deck Crane
The cranes flood lights will be a great tool for scene lighting. Conditions permitting. Crane lights are turned on from the Wheelhouse Exterior Lighting HMI. The light switches in the basket, or on the pedestal are momentary.
