Subsea Lifting
Operations
29 th – 30 th November 2011
Clarion Hotel Stavanger, Norway

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

• AHC via a hydraulic cylinder – combination of passive
and active heave compensation
