Re: [PSUBS-MAILIST] Deepworker 2000 Hatch Lifting Means

[Phil Nuytten <pnuytten@compuserve.com>]

Hullo, Frank:
        Thank you for the kind words on the DeepWorker sub design. We
measured up a business-class airline seat and made a mock-up of it and
built a full scale ergonomic model of the DW around it. The idea was to
reduce the sub volume as much as possible, consistent with full leg, head
and 'elbow' room. The DW's are very comfortable to operate, even after six
or seven hour dives - the 'foot-buckets'                      (
vertical,horizontal thruster controls and linear speed controls) are on a
slideable rack so you can adjust to exact individual leg length - just like
moving your car seat forward and back.
        BTW, for Brent's info: the dome crash frames are made of titanium,
so the sub can be single-point lifted on the crash frame. Very expensive,
but very tough!There are also lifting eyes welded to each side of the pilot
sphere  so the sub can be lifted on a soft strap - We  made crash frames of
aluminum, years, ago - but they're almost all T1 now. 
        There are some recent pics of the DW's on the 'GreenPeace' website
(the DW's did an extensive survey of Zemchug Canyon - northern Alaska -
earlier this year) also on the 'Living Ocean(s)' website - re the location
and HD videop survey of 11 pieces of logging equipment in an Orca
refuge/preserve area called 'Robson Bight' ) depths were 1300 to 1900 feet.
While you're surfin' check out 'Pavilion Lake' (note: only one 'L') re the
microbialite survey/videography we have contracted with NASA and the CSA
(Canadian Space Agency) for this spring - strange stuff!!
