Specifications Definition and Review
A proper set of technical specifications is the primary means by which
a client's expectations are communicated to designers and builders.
Information contained in a technical specification is the measure
by which success or failure is assessed. In the absence of quantitative
guidelines for allowable noise and vibration levels, there is little
recourse in the event of an unsatisfactory outcome. For this
reason (among others) we strongly advocate the use of comprehensive
technical specifications to define allowable noise and vibration levels.
comprehensive technical specification, including limits on noise
and vibration, provides an owner, architect or builder with the
owner's expectations with respect to noise and vibration are unambiguous.
levels help determine the scope of appropriate engineering solutions.
levels provide a means for estimating the cost of treatment options
early in a project.
levels provide the measure against which the finished project
contained in a technical specification can be enforced under the
terms of a contract.
Enterprises has long been involved in the development and review
of technical specifications for noise and vibration in a wide variety
Enterprises has been involved in projects ranging from the world's
finest super-yachts to high performance patrol craft. We
routinely provide engineering services to the world's most prestigious
shipyards, and those desiring a level of comfort comparable with
the world's premier luxury vessels. We are therefore uniquely
qualified to translate an owner's desires into quantitative, realistic
and achievable noise and vibration level specifications prior
to soliciting bids for construction.
Enterprises can evaluate an existing document on behalf of an
owner, marine architect or builder. A specification should
always be reviewed to ensure that the noise and vibration limits
are realistic and within cost and weight budgets. It is
obviously better to discuss the prospect of relaxing noise limits
in contract negotiations than upon discovering a noise problem
during an acceptance sea trial. We understand the engineering,
material and construction techniques required to achieve a quiet
vessel. Given a specification, we can provide critical
information on the difficulty and expense of meeting the targets.
the closing phase of a project, J&A Enterprises provides measurement
services to determine compliance with a technical specification.
We use precision instruments with calibration traceable to the
National Institute of Standards
and Technology (NIST) and highly qualified engineers to ensure
a valid result. A formal sea trial report documenting the
measured noise and vibration levels is submitted for use by interested
