Anchoring Advantages & Disadvantages
CCU MADTS
Advantages:
no complex systems with thrusters, extra generators and controllers
no chance of running off position by system, failure or blackout
no underwater hazard from thrusters
Disadvantages:
Limited Manoeuvrability once anchored
Anchor handling tugs are required
Less suitable in deeep water
Time to anchor out varies between several hours to several days
Limited by obstructed seabed (pipeline, seabed)

3: “”””, including loss of a compartment due to fire or flood ( Atleast 2 independent computer systems with a separate back up system separated by A60 Class Division)
Drill Crew: Tool pusher
Recc
responsible for day to day running of rig
ensure all necessary equipment is available
leader- in charge of drilling department , reports to master or OIM
work closely with company man on actual drilling of well
Drill Crew: Driller
SODDS
Driller and tool pusher are upper supervisory positions
operates drill motor
primiary on-scene decision maker on rig floor
direct actions of assitant driller , motorman, derrickman & roughnecks to ensure smooth rig operations
determine speed and pressure of drill bit and how fast the tool gets pushed into the hole
Drill Crew: Roughneck
unskilled or slightly skilled labourer
drill crew working on derrick floor , screwing together sections of drill pipe while running or pulling of drill string
Drill crew: Derrickman
normally occupies top of derrick
guides stand of 90 ft long drill pipe into fingers at top of derrick while tripping out of hole
while tripping into the hole, pull the pipe out of the fingers and guide it into the top drive of the elevators
standing on fingerboards, move pipe between pipe racks, and the well bore during trips in/out of the hole
physically demanding and wears a safety harness when up in the derrick
Marine Seismic Crew: Party Chief
responsible for succes & quality of survey
overall in charge of operations, captain will follow party chief
Marine Seismic Crew: Seismic Obeservers
assisted by Junior observers
perform data acquisitions and process through survey activity
Marine Seismic Crew : Seismic Technicians
maintenance and immersion of sources & streamers
challenging in high seas
Marine Seismic Crew: Geologist
Analyse data acquire from seismic survey
BOSST VS BOSIET Which one is mandatory?
BOSST is MANDATORY for foregin going vessel
BOSIET is RECCOMENDED for MODU
it is guidance on basic training and is an add on
What is included in TSBB
Crew Basket
FROG
Swing rope
PSCRB vs TEMPSC Coxswain which is mandatory?
PSCRB is mandatory for officers and TEMPSC Coxswian is mandatory for crew
Same course for diff people
PFRB how many crew required?
2 certified crew
Chaser
used for deep water as pendendts will break due to wear
ensure both installation and break-out of anchor without having to use a pendant line/buoy
totally eliminate buoy, partly cable, reduce wear on system
cheaper than mooring line
ROV
tethered underwater robots
unoccupied, highly maneuverable, operated by a person aboard a vessel
linked to ship by tether (cables for electiricity, video, data)
attachments such as sonar, magnetometers, still camera, cutting arm
role: inspection, placing underwater manifolds for development, repair, maintenance
Features
thrusters: move navigate
camera/hydrophones, crew to see/hear
sensors
