Polarcus’ Arctic Operating Procedures Get Official Recognition from DNV in Finland

image

Polarcus Limited  announces that the Company has today received a Statement of Qualification from Det Norske Veritas (DNV) to qualify Polarcus’ Arctic operating procedures according to industry best practice and relevant standards. The Statement of Qualification was presented to Polarcus at the 7th Annual Arctic Shipping Summit in Helsinki, Finland.

The Arctic poses demanding challenges to marine seismic operations. Environmental conditions stress the ship, equipment and crew, limit the window for seismic operations, and pose dangers to in-water seismic equipment. To mitigate these risks in order to safeguard life, property and the environment, Polarcus, with assistance from DNV, has developed a wide-ranging set of Arctic-specific operating procedures.

Commenting on the achievement, Rolf Rønningen, CEO Polarcus, said: “We believe that the environmental, health and safety concerns associated with working in the Arctic demand the very highest level of commitment from companies operating in this pristine and often challenging frontier. Consequently we have collaborated with DNV over the past year to develop a comprehensive set of Arctic procedures to cater for the unique hazards associated with operating a seismic vessel in these waters. We are very proud therefore to receive this Statement of Qualification today from such a prestigious organization as DNV.”

Christian Fjell, DNV Project Manager said: “Polarcus’ active cooperation and input provided early on in the project was extremely helpful in aligning our thoughts and objectives. Our team of experts assessed the completeness and quality of Polarcus’ Arctic operating procedures, internally designed by their team, and DNV proposed areas of improvement based on applicable conventions, regulations and standards. This project has certainly been mutually rewarding as Polarcus was able to provide significant input and reflections on our own suggestions based on their existing in-house competence in this field.”

Well Intervention Units: Faster, deeper, cheaper

image

Rapid technological and market developments in the offshore industry over the past five years have put pressure on class to develop rules and notations for a new generation of specialized well-intervention offshore vessels.

Driven by insatiable global demand for energy, subsea exploration and well construction has experienced a boom in the past decade. According to consultants Infield Systems and Douglas Westwood, the total number of subsea wells will balloon to more than 5,500 by the end of 2010. While some projects may be delayed in some areas due to financing issues related to the global financial downturn, the rapid construction of new wells is likely to continue, if not accelerate, in the years to come.

This remarkable growth has created challenges for energy companies and suppliers alike. Increased demand for energy has forced many energy companies to re-evaluate stranded or marginal fields, work in deeper waters, use more complex tie-back solutions and improve recovery rates for aging wells, which are about 10-20 per cent less than platform wells.

These emerging demands have pushed operators of well intervention units to develop new technologies to improve access to subsea wells, creating a demand for more efficient subsea well intervention systems, including Riserless Light Well intervention (RLWI) units. While not appropriate for deep water, RLWI units are optimal for repair, scale removal, installation and manipulation of some equipment (such as valves, plugs, screens etc.), re-perforations, zone isolation, fluid sampling, PLT, chemical treatment and well abandonment, among other services.

In the past, this work was performed by mammoth, slow-moving semisubmersible drilling rigs, but developments in dynamic positioning systems, ROVs and onboard systems on smaller, mono-hulled vessels which can move quickly from one well to the next, helping to reduce chartering costs and improving well recovery rates by up to 50 percent. Riser well intervention units are still preferred for some kinds of work and in depths below 500 meters, but new composites now being developed for wire lines may soon allow RLWI units to work in deeper waters.

A vessel or an offshore unit?
The first monohull well intervention unit (Seawell) was built in 1986 by WellOps. The concept proved a success, and over the next ten years, demand for LWI units grew. However, because these units are often similar in design to Offshore Supply, Support or Multi Purpose vessels, there was uncertainty on how to class them: Are they vessels or mobile offshore units?

Based on its extensive experience in the North Sea offshore industry (home to about 40 per cent of the world’s subsea wells) and other regions, DNV moved quickly to manage these issues. According to Per Jahre Nilsen, DNV’s Business Development Manager (Well Intervention) the development project, which began in 2007, created some unique challenges.

“At the time, there wasn’t a lot of useful data out there to help us develop the right approach,” he says. “But based on our experience, technical research and feedback from the industry, we concluded that if the unit is capable of taking control of subsea equipment, such as opening or closing valves on a producing well, it would be classed as offshore, not maritime.”

Nilsen says that these criteria are consistent with the way many national authorities differentiate between offshore operation and maritime ships/vessels operation and notes that Mobile Offshore Development Units (MODUs) code compliance applies to offshore. Once developed, the new rules were then submitted to external hearings for review and comments were solicited from owners and operators.

Unique offering
At present, DNV is the only class society offering the Well Intervention Unit class notation. And based on experience gained by developing the new rules, DNV released a new, optional notation known as WELL Intervention in October, 2009.

Nilsen says that defining the parameters for a mandatory class notation for well intervention units required an exhaustive review of different technical elements and a broad range of safety principles, which covered ventilation, areas classification, shut down & gas detection, escape, evacuation and communication. The organisation sourced in-house expertise on structural design, which took into account substructure and foundations for well intervention equipment and drill floors when applicable. Other issues included fire protection, dynamic positioning, and a number of supplementary requirements, ranging from gas treatment in the event of a leakage to rescue ladders in the moon pool.

Nilsen explains that the scope the WELL class notation include 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,” says Nilsen. “We believe the WELL class notation will gain recognition as a mark of quality — an assurance to charterers that the vessel follows internationally recognized standards for well intervention equipment.”

Today, 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 services to subsea fields, 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 will provide subsea intervention, light drilling, and riser and riserless well intervention services.

Alf Kristensen project manager for Aker Oilfield Services, says that the company has two well intervention units classed by DNV – the newbuild Skandi Aker, and its sister vessel, Skandi Santos, now under charter with Petrobras in Brazil. “While there are many components to winning a contract, we felt the DNV notations gave us an advantage over competing oilfield services companies,” says Kristensen. “The DNV notation helped strengthen the charterer’s confidence in our offering and is consistent with our focus on reliability and advanced technology.”

While the Skandi Santos and Skandi Aker are well intervention units and will work without risers, Kristensen says DNV worked to modify the optional WELL notation to fit their needs. “We recognize increased demand for well intervention in deeper water where there is a need for using risers and with riser units we can offer coiled tubing services,” says 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 recognize the commercial potential in time — not just for newbuildings, but for existing tonnage.”

Well intervention units in a class of their own

Rapid technological and market developments in the offshore industry over the past five years have put pressure on class to develop rules and notations for a new generation of specialised well intervention offshore vessels. DNV‘s Alexander Wardwell reports.

Driven by burgeoning global demand for energy, subsea exploration and well construction has experienced a boom in the past decade. According to consultants Infield Systems and Douglas Westwood, the total number of subsea wells will climb to more than 5500 by the end of 2010.

Riser well intervention units are still preferred for some kinds of work and in water depths greater than 500m, but new composites now being developed for wire lines may soon allow RLWI units to work in deeper waters.

Gender issues
The first monohull well intervention unit (Seawell, now operated by Well Ops) was built in 1986 by Stena Offshore and entered service the following year equipped with a 12m long, 13t subsea wireline lubricator built by Camco. The concept proved a success, and over the next ten years, demand for LWI units grew. However, because these units are often similar in design to offshore supply, support or multipurpose vessels, there was uncertainty on how to class them: are they vessels or mobile offshore units?

With its extensive experience in the North Sea (home to some 40% of the world’s subsea wells) and other regions, DNV recognised the need to manage these issues and launched a development project in 2007. According to Per Jahre Nilsen, the class society‘s business development manager (well intervention), the development project created some unique challenges.

The 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 says 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,’ says 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.’
