At 300 meters depth, we have it covered. But at depths up to 3000
meters, the physical conditions demand a radical re-think around
techniques and technology.

Wright’s Well Control Services (WWCS) performed a hydrate remediation in the Gulf of Mexico at 7,200’ water depth from a proprietary skid containing a pump and motor. This self-contained subsea unit is powered from the surface through coiled tubing from a Multi-Service Vessel (MSV). Not limited by a Remotely Operated Vehicle’s (ROV) hydraulic energy, the subsea pump can increase volume up to 1 bpm, or reverse flow drawing pressure down to a sub-ambient -12 psi. For this project the integrated skid cleared 15 miles of 12” pipeline removing 9,000 barrels of hydrocarbons, condensate, gases and other fluids.
For a subsequent job, a paraffin and asphaltene blockage mixed with hydrates was successfully mitigated reopening four miles of pipeline. To date the skid has cleared a total of 30 miles of pipeline.
WWCS Gas Separator - Engineered to Prevent Hydrate Blockages within the Skid and its Coiled Tubing
A unique WWCS gas separator sits atop the skid and removes the gas mixed in the hydrate to the surface. This approach prevents the formation of additional hydrates in the coiled tubing outtakes used by both the gas separator and the pump for the remaining fluids. The old technique required returning the coiled tubing to the surface for thawing each time hydrates formed and reconnecting to the subsea pump–causing costly delays.
This system is further protected from hydrate blockages between the pipeline end termination/flowline end termination and the skid by injecting dispersant chemicals from a ROV panel as needed.
Engineered by WWCS to Ensure Safety
WWCS has engineered in a triple-redundant safety system to compensate for a loss of dynamic positioning (DP) or drive-off by the MSV from which the hydrate skid is deployed. An emergency quick disconnect (EQD) removes the skid’s coiled tubing connections via four hot stabs. Accumulators provide an isolated source of hydraulic power for the EQD which can be activated acoustically from the vessel, with ROV manipulators, or as a last resort with wire ropes. This safety system eliminates potential damage to the pipeline asset from the hydrate skid dragging across the seabed or thousands of feet of coiled tubing crashing down on the remediation site.
Engineered by WWCS to Protect the Environment
The skid has a number of environmentally friendly features. The pump is powered by filtered sea water avoiding any adverse impact from leaking or severing of the coiled tubing. The fluids the hydrate pump sends to the surface are contained in a specially designed tank on the deck of the MSV. Lastly, in the event of a MSV drive-off or loss of DP, emergency shut-off valves minimize the release of any hydrocarbons from the coiled tubing outtakes after an EQD. WWCS is currently developing a flush loop to eliminate any hydrocarbon release from an EQD deployment.
Shallow and Inland-Water Capabilities
The WWCS Hydrate Remediation System is also the solution of choice for shallow and inland-water pipelines. Depending on the

Beyond the EVP: The experience of Subsea 7Havas People
Global changes in the way organisations operate and the economic slump that the oil and gas industry is facing, mean that Subsea 7 have had to drastically adapt their ways of working. Key to this is creating a sense of purpose in the work they do so that their people go through change with them.
The mechanism of steady-state heat transfer from deeply buried pipes has been rigorously modeled for a long time. Detailed
analytical formulae have been proposed recently for the calculation of the overall heat transfer coefficient across the entire
range of burial depths. This paper presents an evaluation of these formulae and suggests some improvements on the basis of
numerical simulations performed with high-fidelity Computational Fluid Dynamics (CFD) models.
Explicit formulae can quickly be implemented and used for generating profiles of overall heat transfer coefficient along
pipelines. The effect of uncertainties in input data on steady-state heat transfer can easily be assessed for any amount of
burial. Four explicit, continuous formulae are presented and compared to three independent sources of CFD analyses. A
relative difference of 10% or less with respect to CFD can be achieved with analytical formulae for a comprehensive range of
offshore pipeline systems, ambient conditions, soil thermal conductivities, and burial depths. The applicability of these
formulae to onshore systems is also evaluated.

Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

Implicitly or explicitly all competing businesses employ a strategy to select a mix
of marketing resources. Formulating such competitive strategies fundamentally
involves recognizing relationships between elements of the marketing mix (e.g.,
price and product quality), as well as assessing competitive and market conditions
(i.e., industry structure in the language of economics).
2. The challenge:
Installation and maintenance
At 300 meters depth, we have it covered. But at depths up to 3000
meters, the physical conditions demand a radical re-think around
techniques and technology.
3. The challenge:
Installation and maintenance
Lowering a subsea production template to a depth of a few hundred
meters, using cables is a relatively straightforward process. But as the
depth increases, the dynamics change. There comes a point where the
weight of the cable played out exceeds that of the template itself — and it
keeps on increasing, placing enormous stresses on the surface vessel. Is
there an alternative method of installing subsea equipment?
Increased depths present additional challenges for the maintenance of
pipelines and equipment. Would it be possible to employ autonomous
remotely operated vehicles which remain on the seabed and are capable of
operating without the need for an umbilical?
These are just a few of the challenges we face. Any good ideas you might have on
subsea installation and maintenance are welcome.
Take the challenge!
4. The challenge:
Separation of oil/gas/water and sand !
We've pioneered robust solutions for separating produced oil and
gas from water and sand on the seabed down to 300 meters. But
greater depths require more resilient, compact and cost-effective
solutions.
5. The challenge:
Separation of oil/gas/water and sand !
We have successfully developed separation facilities which remove the need
to take the produced mixture of oil, gas and water to the surface, and
significantly increase recovery. It works well, but in deeper waters, the
design of the structure simply would not work. There may be other
methods of separation – for example involving centrifugal forces – but how
could these be made to work reliably at depths up to 3000 meters?
We face many challenges. Answers to these, or any other good ideas related to
the separation of oil, gas, water and sand are welcome.
Take the challenge!
6. The challenge:
Produced water disposal
Water separated from the well-stream can be re-injected. But as the
depth increases so do the physical challenges, as well as the costs.
Is there an alternative to re-injection?
7. The challenge:
Produced water disposal
The produced mixture from the wellstream can typically comprise of up to
90% water. In the course of extraction, this means dealing with significant
quantities of water. On a platform, water can be treated so that it can be
disposed of at sea, or alternatively produced water can be re-injected into
the well. At greater depths the cost of bringing the produced water up to
the platform with the wellstream increases and the costs involved in drilling
a well for re-injection become prohibitive. Is there a better, more cost-
effective way of handling water at these depths?
Your answer to this, or any other good ideas you might have related to produced
water disposal are welcome.
Take the challenge!
8. The challenge:
Remote monitoring and control
In our industry, knowledge is power. But placing monitoring and
control systems further from command centers brings out a range
of new challenges over reliability and accuracy.
9. The challenge:
Remote monitoring and control
Temperatures. Flowrates through pipelines. Precise quantities of oil and gas
in the wellstream. These variables, as well as many others, require constant,
accurate monitoring. And yet, at the extremes of the subsea environment,
conventional means of measurement may not always be the most durable.
But what are the alternatives?
The control systems we employ have typically been connected using copper
cable. These are gradually being replaced by fibre optics as a more effective
means of transmission. But there may be other solutions, and the question
of how to power these systems over increasing distances remains.
Do you have any answers to the above, or any other good ideas related to remote
monitoring and control? Please let us know.
Take the challenge!
11. The challenge:
Long distance power transmission
Over longer distances, the principal challenge is how to maintain a stable
power supply to the remote production facilities, which in some cases can
be more than 100 km from land.
In addition, to install electrical equipment such as compressors, pumps and
the necessary electrical controls and switchgear at even greater water
depths is to place them in a particularly hostile environment. One solution
has been simply to encase equipment in a pressure chamber. However,
particular challenges remain – not least how to maintain the integrity of the
chamber, and the electrical connections, especially where power cables
penetrate the chamber walls. What are the solutions that will allow electrical
equipment to keep on working at increased depths?
Your answer to this, or any other good ideas you might have regarding long
distance subsea power transmission are welcome.
Take the challenge!
12. The challenge:
Local power generation and storage
It may be possible to power smaller installations and control
systems using localized sources. But what form could these power
sources take?
13. The challenge:
Local power generation and storage
To avoid the problems presented by the increasing length of power feeds,
one solution would be to use power generated locally to run equipment on
the sea bed. Known means of generating power could include water
turbines, or windmills on the sea surface. But what are the alternatives?
Also, what is the best way to store energy from these power sources? Are
there batteries that could be used at increased depths? Or systems for
storing energy using a flywheel?
We are open to any ideas related to local power generation and subsea storage.
Take the challenge!
14. The challenge:
New materials
Working at extremes of pressure and temperature, subjected to
corrosive and abrasive forces, traditional materials rapidly reach
the limits of performance. But what are the materials that can
replace them?
15. The challenge:
New materials
The environments we work in and the operating conditions we're forced to
deal with place equipment and materials under extreme pressure. Sand
content in the wellstream flowing through pipelines under pressure is
highly abrasive. Sea water and the fluids extracted from subsea wells are
inherently corrosive. Wax and hydrates can form and adhere to pipelines at
low temperatures, causing blockages. In each of these scenarios, and
others, the choice of materials we use could provide a more effective and
durable solution.
But which materials? All good ideas are welcome.
Take the challenge!
