Feature 1 | RULES AND REGULATIONS
a new, optional notation known as WELL Intervention in October 2009. Nilsen explains that the scope of the WELL class notation includes design verification of the well intervention equipment and systems and survey and follow up during fabrication. Once completed or certified, the equipment will follow traditional classification principles and be inspected on a regular basis. “By introducing the new voluntary WELL
class notation together with the revised and mandatory Well Intervention Unit notation, DNV was able to offer owners and operators of well intervention units the same options that owners of drilling units have had in the past,” said Nilsen. “We believe the WELL class notation will gain recognition as a mark of quality – an assurance to charterers that the vessel follows internationally recognised standards for well intervention equipment.” DNV has issued certification for six well
intervention vessels, including four optional WELL notations, for a number of subsea services companies. While the commercial benefits for owners sailing with the optional
WELL notation is difficult to measure, some well intervention unit operators are hopeful the notation will not only ensure the safe operation of their vessels, but help their bottom line.
Early adopter
One early adopter of the new DNV rules was Aker Oilfield Services. Established in 2006 to meet the rapidly growing global demand for subsea maintenance, the company offers fully integrated services ranging from subsea installation and completion to advanced well intervention operations provided by the company’s state-of-the-art monohull well intervention units. The company’s ambitious newbuilding programme will allow Aker Oilfield Services to provide subsea intervention, light drilling, and riser and riserless well intervention services. Alf Kristensen Manager Engineering
Projects at Aker Oilfield Services, said that the company has one well intervention unit classed by DNV – the newbuild Skandi Aker. “While there are many components to winning a contract, we felt the DNV notations
gave us an advantage over competing oilfield services companies,” said Kristensen. “Te DNV notation helped strengthen the charterer’s confidence in our offering and is consistent with our focus on reliability and advanced technology.” Skandi Aker is a well intervention unit
designed for riser based intervention. Kristensen added that DNV worked to modify the optional WELL notation to fit their needs. “We recognise increased demand for well intervention in deeper water where there is a need for using risers, which allow us to offer coiled tubing services,” said Kristensen. “If we see the notation has a positive operational or commercial impact, we will consider working with DNV on other units in our newbuilding programme.” Looking ahead, rising demand for subsea
oilfield services places DNV in a unique position among class societies in this growing industry segment. “We feel the optional WELL notation has intrinsic value and believe owners will recognise the commercial potential in time – not just for newbuildings, but for existing tonnage.” OMT
SYSTEMS ENGINEERING IN SHIP & OFFSHORE DESIGN
21 - 22 October 2010, Bath, UK
First Notice & Call for Papers
Systems engineering brings structure, discipline and teamwork to any large project and has an increasingly valuable part to play in naval architecture and marine engineering design. The prompt delivery of high quality ship and offshore asset designs is made possible by ever more advanced design methods but also poses major challenges as management teams try to balance capability and cost across global markets. The many risks and interdependencies are best addressed within a systems engineering structure that brings together all the disciplines involved and represents a single unified view of the project.
Whether the emphasis is on project management, operations, structural design, equipment configurations or environmental sustainability, the many variables can be captured within a coherent framework that is readily understood by everybody involved. Based on a sound understanding of the original requirements, multiple concepts can be developed with lifecycle management, safety and environmental issues fully integrated from the start.
The Conference will showcase how Systems Engineering principles can make best possible use of the available skills, technologies and tools available to the marine industry as it faces up to the challenges of present and future markets. RINA invites papers from those in the marine industry with a systems engineering perspective on the efficiency of their design processes and the sustainability of future assets.
• Systems Engineering in marine design
• Designing for environmental sustainability • Risk and safety engineering • Applying architectural frameworks • Dealing with multiple concepts • Operations and human factors integration • Product and lifecycle management • Tools & techniques
