Programme<br />
The Norwegian Society of Lifting Technology (NSLT)<br />
continues the success with its annual meeting for<br />
people working with subsea lifting operations. The aim<br />
of the meeting is to improve understanding of issues<br />
related to operations, and create networks between<br />
design specialists, people responsible for selection of<br />
concepts and the installation contractors.<br />
Knowledge ensures a good economy!<br />
The Norwegian Society of Lifting Technology (NSLT)<br />
is often informed that subsea lifting operations have<br />
exceeded the cost budget by several million NOKs due<br />
to lack of knowledge within relevant disciplines. Often<br />
the costs are exceeded because the operation duration<br />
is longer than planned. The seminar will focus on<br />
the various phases of a subsea installation operation.<br />
The focus of the seminar will be to present and exchange<br />
knowledge on various challenges and problems<br />
of various types of marine operations involving<br />
subsea lifts.<br />
Theory and practical solutions<br />
In addition to the presentation of examples that illustrate<br />
various issues related to marine operations, we<br />
will present and discuss solutions based on theory -<br />
hydrodynamics and lifting dynamics.<br />
Target groups:<br />
• Engineers in companies engaged in design/<br />
operation of subsea structures and marine<br />
contractor companies<br />
• Personnel in subsea engineering companies and<br />
other companies performing design of subsea<br />
structures and other equipment and tools used in<br />
an operation<br />
• Competent persons for offshore cranes and lifting<br />
appliances<br />
• Suppliers of specialized tools and equipment for<br />
subsea lifting operations<br />
• Authorities and others formulating recommendations<br />
or evaluation criteria and undertakes<br />
control functions<br />
• Warranty surveyors<br />
• Operational responsible personnel in oil<br />
companies.<br />
