DAV MX Controls Cement
Delivery, Streamlines Ops

The DAV MX circulating sub from Churchill Drilling Tools, has been used to significantly cut process time and costs for two challenging deepwater cementing operations, without compromising string functionality.

The DAV MX runs on Churchill’s MX Smart Dart technology. The valve assembly operates on a piston and spring mechanism, which is activated when a dart is pumped down the drillstring. A range of robust darts are pumped at high speed into a simple sub and catcher.

In a deepwater well in the Gulf of Mexico, following the deployment of several failed lost circulation material pills at 28,000 ft., a heavy cement 250-bbl slurry of 16.6 ppg was directed into the formation via the DAV MX ports. This protected the lower bottom hole assembly (BHA) and delivered the cement straight into the loss zone. The latch-and-seal ability of the DAV MX prevented ingress into the lower BHA, while the lock-open feature permitted bypass at low flow rates to restrict dynamic losses. The controlled cement delivery and the ability to avoid tripping out of hole proved to be a major time and cost-saver for the operator.


Fugro’s New Survey Vessel
Racks Up Work Backlog

Fugro Venturer is the new Fugro purpose-designed, standardized survey vessel. The 72-m vessel is a platform for technological innovation, where Fugro’s trademark technologies, such as OARS (centralized command centers with direct access to offshore survey projects), Back2Base (enabling large amounts of survey data to be sent from offshore vessels to onshore processing centers and clients) and ROAMES (a powerful asset management solution streamlining subsea operations) are radically changing information delivery.

Fugro has secured a significant confirmed work backlog for a campaign of site and pipeline route surveys, for clients including Aker BP, following commissioning and survey trials. Fugro Venturer is contracted to conduct simultaneous analog/digital surveys, 3D high-resolution seismic and environmental sampling and shallow geotechnical operations.


Agreement for New UK Maritime,
Offshore Training Facility

The trade representative body Mersey Maritime announced an agreement to develop a brand new maritime and offshore training facility in the northwest U.K. The cluster organization for the maritime sector in the northwest U.K. has been instrumental in initiating discussions and lining up potential partners from across the region’s public and private sectors to secure the business connections and support needed to bring Glasgow-based Stream Marine Training to Merseyside.

Stream Marine signed an agreement with Wirral Council to invest up to £1.5 million in new facilities at Tower Quays and a new fire training ground along Duke Street, Birkenhead. The investment could also have a significant broader economic impact.

Using the Wirral Waters Investment Fund, Wirral Council has put together a compelling package of support as part of a strategy to strengthen the maritime and low-carbon sectors on the Wirral peninsula. The opening of the new facility in the Mersey Waters Enterprise Zone is set to create up to 25 new jobs.


Pharos Combo to Recover
Subsea Products, Cables

Pharos Offshore Group has paired its trenching and deburial systems with a rugged cable retrieval grab to aid the offshore industry in recovering damaged subsea products and out-of-service cables. Two of the company’s cable recovery spreads were sent out recently to work on the recovery of an array cable within an offshore wind farm in the Irish Sea and the recovery of a section of an interconnector off the coast of Iceland.


Aquaterra to Work on Subsea
Abandonment in North Sea

Aquaterra Energy has won a major contract to supply subsea high-pressure riser (HPR) equipment and services for a subsea abandonment project in the central North Sea. Aquaterra will facilitate the abandonment of 10 subsea wells via deployment of a subsea HPR system from a jack-up rig. The scope of work could be extended to include two further subsea wells, bringing the total number of abandonments to 12.

Riser analysis was completed in-house by Aquaterra and validated by Bureau Veritas. It has confirmed a 50-year return storm operating envelope after HPR and rig optimizations were implemented. This has simplified the project operationally and reduced costs to the operator overall.


LUX Assure Appoints
Partner in Malaysia

Oil and gas technology firm LUX Assure has strengthened its presence in Malaysia with the appointment of a regional partner, Borneo Seaoffshore Engineering SDN BHD.

Borneo Seaoffshore will support LUX in educating the local market on corrosion management best practice, while promoting its CoMic technology, an on-site deployable corrosion inhibitor monitoring kit, which is used to inform better corrosion inhibitor management and to identify if the optimum level of inhibitor is being dosed.


Bluestream to Conduct ROV
Subsea Structural Inspections

Bluestream Offshore has secured a five-year contract, plus two-year extension, with ONEgas, the combined business unit of Shell UK and the Nederlandse Aardolie Maatschappij (NAM) for gas production in the southern North Sea. The contract is for ROV subsea structural inspection services and includes 69 of ONEgas’s offshore platforms and subsea completions in the southern North Sea, U.K. and Dutch sectors.

The contract covers subsea inspection services for which Bluestream teamed with Vroon Offshore Services in Den Helder as a maritime partner for supplying the offshore support vessel during the entire contract duration. For the 2017 campaign, Bluestream is using a DP2 vessel fitted with Bluestream’s own inspection system and fully equipped inspection-class Saab Seaeye Tiger ROV and the compact work-class Seaeye Cougar XT ROV to perform the subsea structural inspections.
