Startup Procedure

[list]
[*] Enter engine room
[*] Set RPM target above 120 (or the engines won't run) and a max of 600
[*] Set throttle for both engines to desired amount (preferably 1)
[*] Switch fuel and air pumps for starboard and port engines to on
[*] Engage starters
[*] If switching to bridge control ensure that the bridge has both RPM target and throttle set to recommended values
[/list]

Tugging Procedure
[img]https://images.steamusercontent.com/ugc/13605096140276591604/D1C8D3B01F27FD638138914906405A71AEE519CA/?imw=5000&imh=5000&ima=fit&impolicy=Letterbox&imcolor=%23000000&letterbox=false[/img]
[list]
[*] Set RPM target to 200
[*] Keep both the vessel to be tugged and Ring Bearer close and stable by using DP system
[*] Disconnect tugging adaptor from front of deck and connect to centre winch
[*] Reel out centre winch until enough slack is generated to pull adaptor to desired anchor point
[*] If using two anchor points ensure they are both within 10 metres of one another
[*] Reel out centre winch and slowly and either disable DP system or change desired position for ahead position
[*] Once confident that the load is connected securely slowly ([b]and I mean really slowly[/b]) increase the target RPM from 200 to a recommended of 400 RPM in increments of 25 while waiting at least 10 - 20 seconds between increment
[*] When turning make sure to take [b]wide[/b] and [b]slow[/b] turns

Anchor Recovery Procedure
[img]https://images.steamusercontent.com/ugc/16176662145084064663/2A3A320F44F14A30D4872ED45C8FBD391101EA77/?imw=5000&imh=5000&ima=fit&impolicy=Letterbox&imcolor=%23000000&letterbox=false[/img]
[b]Before anchor recovery ensure the anchor has the following requirements[/b]
[list]
[*] At least 3 rope anchors (1 in the centre line and 2 at either side) at the top of the anchor
[*] Is heavy but not to the point of which it weighs above 10000+ SKg
[*] Extra rope anchors anywhere convenient so that it can be tied to the deck
[/list]
Now for the actual procedure:
[list]
[*] Enable DP system and have the position hold so that the stern of the ship is above the anchor
[*] Using W/S on the cargo operator seat, overhang the rear gantry over the stern
[*] Reel out the starboard winch (which goes to the stern gantry) so that it reaches the anchor at the bottom of the ocean
[*] Using a diving suit or ROV (ROV not provided and diving suits are in the changing room), connect 2 ropes to the rope anchors at each side of the anchor
[*] Reel starboard winch in [b] until [/b] the anchor has just broke the surface of the water
[*] Unlock stern roller
[*] Rotate stern gantry so that it is overhanging the deck and connect rope anchor from centre winch to centre rope anchor on the anchor
[*] Reel in centre winch [b]while at the same time[/b] reeling out the starboard winch by the same amount
[*] Once anchor is securely on deck raise bollards to prevent it falling overboard and disconnect the stern gantry from anchor
[*] Reel in centre winch till anchor is in desired position on deck and use the overhead gantry to position anchor if needed
[*] Repeat steps for other anchors if needed

Anchor Dropping Procedure
[img]https://images.steamusercontent.com/ugc/14180575010219923517/C617615613AF33213E5496C437994B91B1B73323/?imw=5000&imh=5000&ima=fit&impolicy=Letterbox&imcolor=%23000000&letterbox=false[/img]
[b]Before anchor dropping ensure you have the following required items[/b]
[list]
[*] Some form of buoy with a winch that automatically reels out once in ocean
[*] The actual anchor itself
[*] An offshore platform with DP system (optional)
[/list]
[hr]
[b]Procedure without offshore platform:[/b]
[list]
[*] Once at position enable DP system
[*] Connect buoy winch to centre rope anchor on anchor
[*] Connect top of buoy to centre winch
[*] Use overhead gantry to position anchor
[*] Overhang stern gantry over deck and connect to anchor
[*] Unlock stern roller
[*] Switch the overhanging position to over the stern and raise bollards once anchor is over stern roller (reel out centre winch if needed for buoy)
[*] Raise bollards so that buoy doesn't fall overboard
[*] Reel out starboard winch so that stern gantry releases tension on anchor
[*] Once it is visually confirmed that the anchor is safe to drop into the ocean, lower the bollards
[/list]
[hr]
[b]With an offshore platform:[/b]
[list]
[*] Manoeuvre vessel close to anchoring point of offshore platform
[*] Ensure both offshore platform and Ring Bearer have DP systems enabled
[*] Raise Bollards
[*] Connect the anchor to the winch of the offshore platform
[*] Slowly reel out winch of offshore platform [b]while[/b] piloting ship to the point of which to drop the anchor (ensuring anchor stays on the deck)
[*] Connect the anchor to the stern gantry and overhang it over the stern
[*] Unlock stern roller and lower the bollards
[*] Slowly winch out the starboard winch and the offshore platform's anchor winch until the anchor is successfully on the seabed (ROV may be needed)
[*] Disconnect anchor from stern gantry and reel in starboard winch
[*] Ensure anchor is successfully connected to seabed via offshore platform
[/list]

Backstory
The AHTS "Ring Bearer" is a relatively tame concept for Archridge Engineering's record with it having only a few modifications from the traditional design used on the majority of anchor handling vessels. These changes help improve the accuracy and safety of the vessel's operations and are in no means due to stormworks' physics not having rope collisions. The development of the ship started in late 2028 before being constructed at FJ warner docks and seeing operations all over the sawyern isles. Seeing great use in deploying and transitioning offshore vessels from sea to sea.
