Happy Hour with Zupt

Happy Hour with Zupt

We’ve recently discovered that we have a microbrewery right around the corner from our office. On Thursday nights they have sampling, so being the good neighbor we are – we decided to host ZUPT HAPPY HOURS!

We are taking a break waiting for the weather to cool down and will resume Zupt sponsored happy hours in early October!

If you’re in the Houston area and would like to join us for a beer, please drop us an email at sales@zupt.com – we will then send you a Zupt coupon that gets you free beer tokens for the evening. We are not sure what they will have on tap – but it is an excuse for a beer and a chat. Local food trucks rotate through if you get hungry!.

11 Below are located at 6820 Bourgeois Rd, Houston, TX 77066.

No matter where and when you enjoy a beer – please drink responsibly. We will arrange a ride for you if you decide you should not drive.

A First for Inertial Metrologies in Mexico

A First for Inertial Metrologies in Mexico

In a joint effort, Zupt and Harkand carried out the first deep water diver based inertial metrology in Mexico’s waters at a record-setting 380 fsw in the Bay of Campeche. The completed survey project was in support of the installation of an expansion spool piece for a new pipeline and platform campaign.

The efficiency of Zupt’s inertial solution, combined with the skill and expertise of Harkand’s personnel, allowed the client to have results within 12 hours and fabricate the expansion spool piece in two days.

The Right Technology for the Job

The Right Technology for the Job

Due to the unpredictable nature surrounding offshore survey operations (think: low visibility, ROV failures, vessel changes), it is imperative that operators can count on survey solutions to work, and to work every time. Emerging technologies such as LiDAR are appropriate for some applications, but they also have inherent shortcomings that impose major financial risks on operators. Zupt’s inertial solution provides reliable, accurate, and efficient metrology operations, with quick delivery turnaround.

Visibility – Reliability:
LiDAR surveys are extremely vulnerable to the effects of high turbidity and low visibility. In the event that visibility goes south after the survey crew has been mobilized and vessel time committed, operators risk losing hundreds of thousands of dollars waiting to collect metrology survey data. Zupt’s C-PINS is always able to deliver metrology results even in the most extreme low visibility situations, without any loss of accuracy.

Attitude Accuracy:
Laser surveys deliver hub attitude data based on a one-sided, sparse, point cloud data set that is then “cylinder fit” onto a very small vertical cylinder (highlighted in below image). It is still uncertain what quality metrics are used to support the data that is delivered by subsea LiDAR for hub attitude. Zupt delivers metrology surveys with attitude specification of as little as 0.5° (2 sigma). We are able to prove our accuracy (often less than 0.1°) with known quality metrics. If the connectors need precise hub pitch, roll and heading data, inertial is the optimal solution.

Efficiency:
Mobilizing LiDAR equipment onto the ROV requires splicing into the fiber can of the ROV which will easily take 6 hours with the ROV on deck. Often, due to operational or ROV issues, we have to move from one ROV on board to another at short notice. C-PINS is up, running and the ROV is in the water within 30 minutes. This will not be the case if you need to break into the fiber bottle on the second vehicle. What if you need the metrology team to move to the rig to complete the survey? In many cases rig ROV support personnel will not have the skills needed to interface survey equipment through the fiber channels on the ROV.

Timely delivery:
Once data collection is complete, the LiDAR data set (as much as 200MB) has to be sent ashore and a substantial amount of time is necessary to process the data into a deliverable. Metrology isometrics are on the critical path to first oil. Zupt’s skilled offshore survey teams make the delivery offshore within 12-24 hours of recovering the ROV after data collection.

Consistency:
With nearly 140 metrology surveys to date, Zupt and C-PINS continue to provide the deliverables for jumper fabrication within the tightest deadlines and to the highest quality.

Zupt to Give Away a BMW M3 at Ocean Business 2015!

Zupt to Give Away a BMW M3 at Ocean Business 2015!

April Fools! We admit it’s a bit mean to pull an April Fool’s prank a week after the fact, but we had to get your attention somehow!

Zupt will be at stand M3 at Ocean Business 2015, and unfortunately, no – there will not be a BMW M3 giveaway. Sorry about that. But while we still have your attention, we’d like to point out some scientifically-proven, consumer-tested comparisons between the stylish and very cool 2015 BMW M3 and the equally stylish, and equally cool Zupt C-PINS.

Horsepower:
The BMW M3 boasts 425 horsepower to get you from point A to point B in no time flat.
Zupt C-PINS consumes only 75W and will give you the precise position of both Hubs using our inertial navigation technology for a quick and reliable metrology.

Fuel Economy:
The M3 gets 26 mpg, which for a sports car is pretty darn good.
Zupt C-PINS doesn’t even take gas, but the efficiency doesn’t end there. With no need to set up an array before metrology surveys, C-PINS makes marine construction surveys more efficient.

Technology:
The M3 has M TwinPower Turbo Technology. Whatever that means. It sounds really cool.
Zupt C-PINS utilizes ultra-cool inertial technology that requires no line of sight, and noise is not an issue in busy marine construction operations.

Service:
The M3 comes with no-cost maintenance for 4 years, apparently.
Zupt C-PINS comes with service from the best inertial surveyors around who can provide offshore deliverables within 12 hours from the completion of a metrology.

In all seriousness, we’d love if you would pay us a visit at our stand. We’ll be there to talk about our inertial metrologies and other C-PINS applications, as well as the progress of our video mosaicking technology. Big things are happening at Zupt, and we’ll be at stand M3 to talk all about it.

See you there!

Specialized Tooling for Your Metrology

Specialized Tooling for Your Metrology

We’re all aware of the complexity of subsea structures. With different types of wellheads, manifolds, PLETs and FLETs come different types of connectors. Having dealt with horizontal, vertical, stab and hinge over (SHO), slip flanges and many other hub types, Zupt has developed a variety of tooling specific to each connector. Our focus is not only on precise and accurate data being collected for metrology surveys, but also operational efficiency during data acquisition.

Zupt’s subsea inertial navigation system, C-PINS, has been interfaced to a large variety of receptacles. From our experience, we felt the need to develop a standardized receptacle for most of these operations. This design was based on the commonly used smart wire receptacle (SWM). To achieve higher accuracy in heading pitch and roll, we made the footprint slightly larger than the SWM receptacle and modified the original receptacle design to increase operational efficiency. This drawing set is available free of charge from Zupt.

In addition to the receptacle, Zupt has optimized our standard rotating stab to provide easy 360 degree rotation while stabbed. This stab locks into place every 90 degrees of rotation to allow us to remove any instrument mounting offsets from the attitude data collected by C-PINs.

When a standard receptacle is not available custom tooling is used. Some examples of this tooling:

If receptacles are not available on the structure, we can install temporary tooling to establish known offsets to reference points on the structure such as this trouser plate below:

These examples are just a few ways Zupt utilizes different tooling to allow C-PINS to interface to a variety of subsea structures. Zupt excels at providing custom solutions to unique tooling issues.
