He found himself on the vessel seduced by the romance of the sea.To preserve the fish and mollusk breeding areas and not to muddy the bottom waters all the sludge as well as other waste is taken away in containers to a special onshore disposal base. We are going home, while the drilling rig crew is to finish the construction of the exploratory well at the Yuzhno-Kirinskoye field.There are four lifeboats on the SSDR to carry 64 people each. Currently, Severnoye Siyaniye is drilling its first exploratory well 3,200 meters deep.Before getting onboard the Fos Universe ship of a Panamian company we had to go through customs and border control as well as all the procedures required for crossing the state border, as the operations area we were heading for was located outside the Russian territorial waters. That is why all sorts of dishes are cooked here with no emphasis on anything particular, as the crew is multinational. It takes from 2 to 4 days to install such an SSDR depending on the conditions, and the process is very painstaking.

We visited the Severnoye Siyaniye (Northern Lights) semi-submersible drilling rig (SSDR) – one of the several rigs constructed over the last years on Gazprom’s order at Vyborg Shipyard. However, Severnoye Siyaniye is designed to operate in harsh climatic conditions, and that is why it doesn’t stop its operation even China Check Valves Manufacturers https://www.xiervalve.com/product/upvc-one-way-valve-butterfly-valve/upvc-new-check-valve/check-valves.html when the sea is very high. As the floating rig is power-propelled, it can also move by itself.The aim of drilling is to prove the reserves and update the geological structure of the Yuzhno-Kirinskoye field.By the way, before our arrival one of the vessels couldn’t unload because of the high sea and had to float nearby for several hours waiting for the sea to calm. The annular space at the wellhead is sealed with the help of special sealing rings. Although during the whole drilling process there is drilling fluid in the well, which creates back pressure in the wellbore. He was invited specially for the Russian shift workers whose stomachs are not used to Asian cuisine. It serves as a safety valve allowing no gas discharge like a cork in a bottle of champagne.At first, a pilot wellbore of the smallest diameter is drilled (215. Our journey started from the port of Korsakov not far from Yuzhno-Sakhalinsk.After the safety meeting we got acquainted with the operating process.Once the well is drilled and geophysical research is conducted, the production column is set and well testing begins.Severnoye Siyaniye is managed by two men.With the help of the tugs the SSDR is positioned in relation to cardinal points based on the results of meteorological studies and is fixed by 8 anchors weighing 15 tons each – two anchors for each of the platform angles. Ships do not moor at the platform – they need to have the system of dynamic positioning. The photo shows 8th grade driller Evgeny Tkachenko controlling the exploratory well drilling process. That is to say, there are twice as many places available compared to the permissible number of people on the platform in order to evacuate the personnel from one of the boards if necessary. For the moody Sea of Okhotsk force 8 storms are not uncommon, and sometimes there are even force 10 storms. The photo shows the master control room or, as sailors call it, the captain’s bridge.Once the drilling is finished and all the necessary data is obtained, cement plugs are placed in the spots where the perforator worked, drilling fluid is pumped into the well and a corrosion cap is placed on the wellhead.Photo: Chief Engineer for Shipboard Equipment Yury Chernov and Auxiliary Operator for Boiler Equipment Viktor Grigoryev monitoring the operation of respective SSDR systems. In our presence drilling tools were lowered 1,750 meters deep with the help of DP stands.A huge crane takes pipes from racks and delivers them to the rig floor.During the drilling process much sludge is brought to the surface from the soil together with the drilling fluid which is then desludged through a special vibrating shaker (in the photo).At first, it all seemed to be a fascinating sea cruise.Ready to leave the platform, we suddenly saw a smiley face in the engine space where the main diesel-driven power generators are situated. It was a bit scary – after all, it is not a ride in an amusement park where such baskets are securely fixed.Deputy Chief Engineer Roman Okishev (Gazprom Geologorazvedka) says that sea soils are not more complex than, for instance, in Western Siberia. Photo: 8th grade drillers Sergey Makarov (front) and Evgeny Tkachenko (back).Yury cooked the most delicious dishes for us. This problem, as we have already mentioned, is solved by remotely operated vehicles that make it possible to see everything under the sea on the drilling rig monitors.But it turned out to be nothing of the kind… After departing the Aniva Bay and entering the Sea of Okhotsk the ship started rocking back and forth.The gas of the Yuzhno-Kirinskoye field, with its current C1+C2 reserves estimated at 563. Marine operations start (towing, mooring and weighing, independent relocation) and the SSDR Captain Valery Solomatin (center) takes the lead. In case of alarm every crew member has to put on a drysuit and a life vest and before boarding a lifeboat to turn over a tag with its vessel number so that once the crew has boarded the lifeboats, it would be clear who is to be searched for on the platform before the evacuation. Then the column is lowered down the hole and is cemented in place, and drilling for a smaller diameter column starts deeper, and so on.All the blowout prevention equipment nippled up on the wellhead rises from 1.

Photo: 5th grade cook Yury Gomenyuk serving lunch at the SSDR galley.A lifeboat is basically a capsule that can go through fire. The pipes are made of a very thick metal specially used for deep-well drilling. During the 2013 navigation period Gazprom is drilling two exploratory wells at the Yuzhno-Kirinskoye field offshore the Sea of Okhotsk (Sakhalin III project).Before the SSDR is installed, the seabed is investigated by remotely operated vehicles (ROV), or robots in other words, in order to exclude the presence of scrap metal, shipwrecks, boulders and gravels that could appear in the time period between the survey procedure and the rig installation.An offshore well geometry is represented by casing columns run in and cemented consecutively from a bigger diameter to a smaller one. It all takes place during two minutes approximately. On the left is Chief Mate Dmitry Karpov, on the right – Second Mate Andrey Nikolichev.In addition, there are 8 inflatable liferafts to carry 35 people each.The storm (which, in fact, can hardly be called a storm in terms of the Sea of Okhotsk) was rated by the local seadogs at about force 3. The cooks work around the clock in two shifts.And so our tour to Severnoye Siyaniye ended.A lifting crane picked up the basket, raised it high in the air……and delicately put it down in the center of a helideck where we were heartily welcomed by the crew. It is aimed at proving the presence of near-bottom gas and determining the setting depth of the first casing column.We had to ascend from the ship to the platform almost as big as a football field and as high as a 43-storey house (the platform height from the lower part of the pontoon to the top of the derrick is 128 meters) in a six-seat basket. All of them were very friendly and we had no difficulties communicating even in our broken English. After the end of testing the drilling fluid is pumped into the well and gas is squeezed back into the formation.Different diameter casing pipes are used during well construction (the deeper into the well, the smaller the pipe diameter, as the well design resembles that of a telescope).The platform arrived at the drilling site from the port of Kholmsk (Sakhalin Region) with the help of two tugs.The platform also acts as a mini-port serving up to 3–4 vessels a day.

When the drilling rig changes its location, the whole drilling crew goes ashore, and only the runner crew stays.These robots are engaged in the drilling process, too. The main difficulty is that in the sea one can’t see either a downhole (well bottom), or a well mouth (its top).

It was conducted by Second Mate Andrey Burkov.The crew was mostly Indonesian. Specialists accurately locate the positioning point by satellite according to the preset coordinates that are determined as part of a survey procedure. Then well pressure is reduced, gas inflow is induced and equipment onboard the SSDR records the gas flow rate (volume of gas produced from the well per unit time) and gas parameters.September 27, 2013Gazprom has a unique experience of operations on the Russian continental shelf. Unfortunately, we didn’t want to eat that much due to the ship motions. There is a lounge, a gym, a cinema hall, a sauna and, of course, a medical room.When desludged, the drilling fluid is once more pumped into the well with the help of the pumps you can see in the photo. Its fuel tank is sufficient for 24 hours of run-time without refueling, and it can move at a speed of 6 knots and tug rafts, too.During this process the platform is towed into position by two steamships.6th grade driller assistants Shamil Uvaisov and Sergey Potapov are pulling down the hand-held slips that additionally clamp the pipe in order to fix it in the rotor. Today we would like to acquaint you with a complicated process of marine drilling.8 to 2 meters above the sea level. It can drill wells up to 7,500 meters deep at sea depths from 70 to 500 meters.

Every day about 200 meters is drilled.The Severnoye Siyaniye SSDR is capable of constructing exploratory and production wells in the temperature range between −30 to +45 °C.And somebody was watching movies in the local cinema hall.First off is a safety meeting. If there are several potentially productive horizons in the formation, the testing is conducted from bottom upwards. In addition, anti-sweep protection is installed on top in case of vessels passing, boulders and stones hitting.We got to the site in the same way, as do the shift workers who work there.Their task is not to miss indicators of abnormal gas blowout.Drilling data is displayed in the driller’s cabin where looking at the monitors he controls the bit (a rock destruction tool) load, the desired drilling speed, etc. They are also used for continuously monitoring the wellhead condition.The photo shows the so-called spider, which holds one pipe with one ‘tentacle’ and grabs another one with the second ‘tentacle’ twisting them together. The SSDR Head Alexander Demchenko (right) manages the crew from the moment of positioning the SSDR at a drilling site till the moment of repositioning. There are all the things needed in a lifeboat, namely, a survival kit, an emergency kit, a wireless station, etc.A special mood was set by our seacook Yury Stakhov who appeared to be an artist by trade.And finally this immense facility appeared on the horizon like a mirage. Perforators are lowered into the column to chamber holes in its sides.Drillers control the process with a joystick as if playing a computer game and talking on the two-way.We were to ride this ship for a bit more than a day, as the way from the port of Korsakov to the Yuzhno-Kirinskoye field is long, namely 824 kilometers or 445 nautical miles.

Updated clutch-cable routing minimizes engine heat on the cable and decreases the force required to pull the lever, something that every rider will appreciatelap in, lap out. In the case of the 2015 CRF motocrossers, that meant putting in long hours at motocross tracks across Southern California, helping to determine the final suspension and powercurve settings. For simplicity ’s sake, both compression adjustments are on the left side, while the rebound clickers are on the right, and all are convenientlylocated at the top of the fork legs. THAT ’S BETTER FOR AVERAGE RIDERS BECAUSE THEY ’RE NOT ALWAYS ABLE TO MAINTAIN MOMENTUM IN THE CORNERS, SO THEY TEND TO ACCELERATE FROM THE BOTTOM QUITE OFTEN. The first thing I noticed wasthat the motor is stronger—you feel it right away," he says. All adjustment clickers are located at the top of the shock body and are easily accessed via a cutout in the right side panel. For many riders, the three basic ECU map options will be plenty, but there are some who will want further customization. BEYOND THE ENGINE, I LIKE THAT THE SUSPENSION ADJUSTERS ARE MORE SENSITIVE, SO CUSTOMERS WILL DEFINITELY BE ABLE TO FEEL IT EVEN IF THEY JUST MOVE THEM A CLICK OR TWO. The ability to quickly and easily change a bike to suit track conditions or riding style is a key to dropping lap times, and thanks to a motocross-first Engine Mode Select button and a latest-generation KYB PSF2 air fork, the new CRF makes it simpler than ever for owners to customize their ride experience. With the CRF450R, changing the fork ’s spring rate is as simple as altering the unit ’s air pressure, and since a standard Schrader valve is used, the operation can be done with a basic airpump and pressure gauge—as straightforward (and affordable) as changing tire pressure.Building Character PROFILE: HONDA R TEST RIDER TIMMY WEIGANDDuring his 14-year career as a professional racer, Timmy Weigand has done it all, competing in various disciplines in both the U. PACKAGING The exhaust system is now shorter and closer to the bike ’s center of mass,resulting in improved handlingBRAKES To slow the CRF450R, Honda added wave-style brake rotors front and rear." While the standard mode can ’t be altered, modes 2 and 3 can be reworked via laptop computer and an available HRC® fuel-injection setting tool (customers who own last year ’s tool only need update their software). Often it ’s the small things that can make or break a rider ’s experience, and the new CRF450R is more than the sum of its parts. TIRES Derived from AMA Supercross experience, Dunlop ’s new-generation Geomax MX52 tires come stock on the CRF450R. Of course, it has always been feasible to compensate for rider weight and track conditions by swapping out coil springs or adjusting preload, but in practice, some owners were dissuaded by the expense and complexity.Never before has experimenting with EFI mapping been so user-friendly. A new heat treatment of the piston increases strength and durability, and new Nickel Chrome Molybdenum transmission gears (10% stronger than the Steel Chrome Molybdenum partsthey replace, with no weight penalty) add to Honda ’s legendary reliability.Engineering SpotlightWITH THE 2015 HONDA CRF450R, CHANGING POWER CURVES IS ACCOMPLISHED WITH THEPRESS OF A BUTTON Simultaneous with the advent of electronic fuel injected motocross bikes (2009, in the case of the Honda CRF450R) was the possibility for tuners to change the engine ’s power curve. To switch between modes, press the EMS button (located next to the throttle) and hold for about a second (throttle must be closed and the engine idling).. Meanwhile, a number of other calculated updates have further improved performance and Honda ’s renowned reliability, ensuring that the bike ’s status as the class benchmark is maintained. THE OVERSIZE FRONT DISC ADDS STOPPINGPOWER AND BETTER FEEL TO THE BRAKE.S.Whether you ’re a pro like factory Honda racers Trey Canard and Cole Seely or an amateur vet rider at your local track, one thing that all motocrossers value is adjustability that makes a difference, which is why the 2015 CRF450R is bound to be a big hit. Fuel-injection settings have been updated as well, while new radiators boost engine cooling. OTHER CHARACTERISTICS OF THE KYB PSF2 SYSTEM: Redesigned 32mm cartridge is in the conventional, upright position, resulting in half-pound weight savings over previous KYB PSF Self-lubricating system utilizes a check valve that distributes working fluid between the inner and outer sections during the compression stroke, keeping the bearing well-lubricated and reducing the Friction is reduced by approximately 10% and operability improved through a design that uses internal-charged pressure, eliminating the sealing material Meanwhile, the rear suspension has been upgraded as well, with the KYB shock now featuring both high- and low-speed compression damping for 2015 (in addition to the single rebound-damping adjustment). The rear features patented blockon- block technology that offers improved traction, while the front also boastsbetter cornering feel. Apart from his two years Down Under, the Southern California native has ridden Hondas his entire career, whether as a privateer supercross/motocrosser, a member of the Moto XXX motocross team, or with the Johnny Campbell Racing off-road squad, which dominated Baja for years.For 2015, that ease of adjustability has been extended beyond the spring rate to the damping.I NEVER REALLY TRIED TO GO FIND ANYTHING ELSE. Betterpower, shifting and braking culminate in an unrivaled ride experience.THE COMPLETE PACKAGE: UPDATES ABOUND ONHONDA ’S CRF450R While the big news for the 2015 Honda CRF450R is the EMS switch and updated suspension, Honda didn ’t stop there. That means less weight for the damping system to contend with whenever the stanchions change direction (frequent on rough motocross tracks!). The internal structure is completely different for 2015," explains KYB technician Kaz Chiba. As a result, the engine delivers more top-end power and over-rev, while an increase in flywheel mass helps to maintain predictable low-end torque and make the engine less prone to stalling. With an air spring, it ’s possible to change spring rates without changing any parts," Chiba says. I ALSO THINK HAVING THE DIFFERENT POWER MODES IS COOL BECAUSE THE BIKE OFFERS SOMETHING FOR EVERYBODY. STYLING Accompanying the CRF450R ’s technical improvements are aesthetic updates, including a Renthal handlebar pad, new CRF graphics on the radiator shrouds and a number of blacked-out accents, including the rear-brake disc guard, rearcaliperguard and radiator grills. In addition, the fork is even lighter than on the 2014 bike. Because the cylinder is larger, there ’s more damping control," Chiba says. For 2015, that trend continues, with the 450 coming standard with KYB ’s latest-generation 48mm PSF2, which offers more suspension-adjustment options (including four-way independent damping adjustment) that are simple to engage.THE CHANGES TO THE POWER CURVE LET YOU GET TO THE TOP OF THE POWER RANGE QUICKER. The number of flashes emitted by the button ’s blue LED corresponds to the selected mode, so getting areminder is as simple as giving the button a quick push. And of course once the modes have been modified, actuating them is easy with the EMS button. You can change the fuel map and also the ignition-timing map," says HRA Senior Engineer Hide Hanawa." One of the main advantages of air-sprung suspension has always been reduced mass, thanks to the elimination of metal coil springs. In addition, the newest PSF has clickers for no fewer than four damping adjustments: high- and low-speed for both compression and rebound. If a customer buys an aftermarket exhaust, it ’s easy to adjust for that. Weigand was hired on a contractual basis as a test rider for Honda R, where he works with HRA Senior Engineer Hidenori Hanawa.Weigand ’s new position means he ’s one of the first riders to try new Honda models, and he liked the CRF450R immediately. I made a list of companies that I had longtime relationshipswith and thought it might be nice to work for," Weigand says.The most common situation for selecting mode 2 would PPR Ball Valve Company https://www.xiervalve.com/product/upvc-compact-ball-valve/ppr-ball-valve/ be when traction is limited and superior throttle control is most useful, while mode 3 could be chosen if soil is loamy and traction plentiful. A new throttle-return spring also has a lighter pull. I ’ve been with Honda forever," says Weigand, who often purchased hisbikes through the manufacturer ’s race-support program. There ’s a new four-valve Unicam cylinder head and exhaust routing (the header pipe now exits to the right and no longer winds around the frame ’s down tube), along with a larger internal diameter for the twin tail pipes. Time to adjust your concept of what ’s possible. HONDAS ARE GREAT FOR PRIVATEERSBECAUSE THEY LAST FOREVER!"That loyalty paid off after Weigand finally decided to retire from racing at the end of last season. Another important attribute of the PSF is increased (and easier) adjustability.Editorial Narratives Assets STORYLINES AND TOOLS SOMETHING IN THE AIR: IMPROVEMENTS TO KYB ’S PNEUMATIC FORK, SIMPLIFIED ADJUSTMENT HEADLINE THE CRF450R ’S SUSPENSION UPDATESEver since outfitting the 2013 CRF450R with KYB ’s Pneumatic Spring Fork (PSF), Honda has been at the forefront of the current air-suspension wave. It offers better out-ofthe- crate performance and more trackside adjustment than ever before. For future CRF year models, he ’ll be involved earlier in thedevelopment process as well. Several other updates improve the rideexperience in ways that are easily overlooked: POWER PLANT The 449cc engine offers improved performance throughout its expanded power spectrum. With less unsprung weight, the front tire is on the ground more often, increasing rider control. Now the fork has a self-lubricating, open-bath system, which makes damping action smoother. and Australia. Until now, such adjustments necessitated connecting a computer via a special adapter, but with the 2015 CRF450R, actuating different power curves is as simple as pressing a handlebar-mounted, three-way Engine Mode Select button (EMS)—an industry first formotocross machines.IN STOCK FORM, THE CRF COMES WITH THREE DIFFERENT EFI/IGNITION MAPS: STANDARD (MODE 1),SMOOTH (MODE 2) AND AGGRESSIVE (MODE 3)."Weigand ’s new stint as a Honda employee is off to a good start, with early signsindicating it could last even longer than his stretch as a Honda racer. The front rotor is also 20 millimeters larger (260mm) for better stopping power andHonda ’s signature linear feel.
