Hi
Dan,
I agree,
it's not worth bringing up for discussion whether drilling and bolting is the
right way to install viewports. All the experts say otherwise and ASME
doesn't allow for it. However, I'm still interested in hearing their
reasons for choosing that design since it is not ABS approved and
frankly, fabricating an ABS approved design would not appear to represent a
financial burden to them. I can't understand their choice. It
can't be ignorance or stupidity since their are some educated people
associated with the design. What seems left is just a conscious decision
to ignore the standard. For what reason?
Jon
Jon,
Holes drilled in acrylic viewports is not a good idea. Mrs. Stachiw
said so , Greg Cottrell says so and ABS says so. We have beat this one
to death already.
