Dear
Bladed User,
Welcome to issue 3 of the Bladed Newsletter.
This newsletter is designed with you in mind and we hope that you
enjoyed the last issue (sent to you in March 2017).
If there are any features or additions that you like to see in future
issues, please email Bladed Support.
Best regards,

Update on supported versions
Migrating
a turbine design project from one version of a calculation engine to
another is a complex task, as inevitably some loads will change.
Therefore, any new version of Bladed released is supported for many
years, even past the point where it is superseded by a newer version.
We currently maintain Bladed 4.6 and newer in full support; these
versions receive regular maintenance updates and fixes. We will
continue to provide email support and carry out investigations into
issues identified in Bladed 4.4 and 4.5, but fixes will only be made
in specific cases according to demand.
Log of known issues
Each
Bladed update includes improvements and fixes to the engineering code
that addresses the shortcomings in previous versions. When making
engineering decisions based on Bladed results, it's important to
understand which version of Bladed was used and whether any code issues
in that version are likely to have impacted the load calculation
results. The log of known issues spreadsheet contains a filtered table, so a methodical
check can be made.
Verification report for Bladed-Sesam
interface, including superelement functionality
Bladed
engineers from Bristol, UK and Sesam engineers from Hovik, Norway, have
been working together to verify the interfaces between the two tools.
The study included checking the conversion of a Sesam support structure
model to a Bladed integrated model and a Bladed superelement model. It
was shown that the two software packages give comparable load and
deflection predictions when using either integrated or superelement
modelling approaches for the support structure. Conversion of the
simulation results and support structure model from Bladed to Sesam
formats was also verified.
The verification study allows designers to use Sesam together with
Bladed in a single workflow with confidence in the accuracy of the
conversions between the tools. The verification report has been
published and is available here.
Bladed Cloud
Bladed
Cloud is a secure platform created and maintained by DNV GL. It
provides users with the capability to run simulations and calculations
without needing to set up and maintain a local IT infrastructure. It is
hosted on the Amazon Web Services platform and uses the Amazon “Elastic
Compute Cloud (EC2)” as its computing backbone, allowing users to scale
up/down their hardware requirement automatically and transparently.
This capability is delivered to users through the Bladed Batch
Framework, which allows users to specify that jobs run in the Bladed
Cloud (as opposed to Batch Runners on the local network).
The use of Bladed Cloud is tracked and billed based on computational
time used. This enables users to obtain significantly higher throughput
than their traditional setups will allow, yet pay for just the total
time they have used.
Andrew Cordle, Senior Engineer, Turbine Engineering
Support said: "On
a recent offshore project we were faced with the
seemingly impossible task of running over 130,000 ten-minute
fatigue simulations in just a few weeks. However, with the use of
Bladed Cloud we could complete batches of around 15,000 simulations
overnight and finished all the simulations on time. This really is a
game-changing technology for running large-scale Bladed calculations.”

Training courses
 Floating wind turbine
modelling training
Floating wind is becoming a reality, with several multi-MW
demonstrators operational. Therefore, we are very excited to announce
the first Bladed floating wind training course to support this sector
of our industry. The four-day course will be held in Paris, France from
26-29 September. Obtain more information
from the registration page.
To express your interest in floating wind training, please email jamie.badar@dnvgl.com.
Events
 Bladed and Turbine
Engineering Support (TES) open day in India
To
coincide with Windergy (India’s main wind conference), TES and STP
delivered an open day with an agenda aimed at turbine manufacturers and
independent power producers. Rob Rawlinson-Smith and William Collier,
both senior TES members, delivered presentations to a full room of avid
engineers.
China
open day in October
A one-day Bladed open day is being planned in Beijing, China on Monday
16 October. The open day will coincide with the China Wind Power event,
enabling wind professionals to take advantage our of open day,
whilst attending China’s flagship conference. Please email jamie.badar@dnvgl.com if you would like to attend this open day.
