March 2017 Issue

Six-Month Delay for New
Offshore Financial Rules

BOEM issued a note to stakeholders announcing a six-month delay in the implementation of strict new financial assurance requirements, NOIA reported. The stay allows offshore operators who share liability for decommissioning of wells and facilities more time to come up with additional insurance, bonding, set-aside funds or other safeguards to ensure that they can meet the cost of decommissioning.

In December, NOIA, LMOGA and OOC sent a joint trades letter to BOEM Director Abigail Hopper summarizing critical industry concerns regarding the financial assurance requirements. NOIA also helped shape letters from 31 U.S. House representatives and 14 U.S. senators that urged Interior Secretary Sally Jewell to suspend implementation of the financial assurance requirements.

Development of UK
Offshore Drone Guidelines

Cyberhawk Innovations, which conducts aerial inspection and survey using drones, has welcomed Oil & Gas UK’s new guidelines on the use of drones in offshore environments. Cyberhawk was the first company to operate drones in the North Sea, back in 2012.

Cyberhawk played a key role in drafting the Unmanned Aircraft Systems Operations Management Standards and Guidelines, which were produced by Oil & Gas UK in conjunction with a working group, including drone operators and industry and aviation safety experts. These guidelines recognize that adoption of drone technology will continue to grow.

InterDam Tests Fire-
Blast-Resistant Panel

InterDam, supplier of fire and blast doors, walls and windows to the offshore oil and gas and renewable sectors, is in the final stages of testing a new prefabricated fire- and blast-resistant panel, the Generation V, in response to the industry’s desire for using fully fit-for-purpose prefabricated walls that fit modular and standardized building designs. InterDam has tweaked the panels’ insulation material by realigning the layers of fibers and optimizing the panel support structure to absorb more energy. This new concept was field tested using three sample positions. These tests included damaging the panels to study their breaking point and proving that they are gas-tight after a blast pressure of 0.8 bar. Further testing will be carried out at a fire test lab in the U.K.

Analysis of offshore accidents indicates a combination of a blast and a fire in more than 50 percent of cases.

EES to Provide Service
To Prevent Marine Growth

Evoqua Electrochlorination Services (EES) has been established to provide a total after-sales service solution for all electrochlorination marine growth prevention systems (MGPS), regardless of the manufacturer or design. This provides a single supplier for more cost-effective, expedient means of supporting MGPS maintenance requirements. The new service is available for all marine, oil and gas, and power industry customers.

The prevention of marine growth in offshore oil and gas rigs, drillships, FSPOs, FSOs and FSRUs is critical to operations. If, for example, untreated water is injected into an oil well and there is buildup of marine organisms, production can stop. Reliquefaction processes can also be affected, resulting in considerable downtime for operators and owners.

Charter Extension for
Bibby DSV in North Sea

Bibby Offshore announced the long-term extension to the charter of its dive support vessel (DSV) Bibby Topaz, owned by Volstad Maritime. This charter extension allows Bibby Offshore to maintain and grow its share in the North Sea DSV market. The new contract runs through December 2019, with options to further extend the charter to the end of 2024.

GE MV7-5L Drive for
FPSO in Greater Enfield

GE Energy Connections was chosen to supply its MV7Series 5 Level (MV7-5L) drive, which will sit topside on an FPSO unit for the Greater Enfield project. Located 60 km off Exmouth in western Australia, the project aggregates production from the Laverda Canyon, Norton over Laverda and Cimatti oil accumulations. The MV7-5L drive with ultimate waveform configuration supplied by GE’s Power Conversion sub-business will help start and control two multiphase pumps operating in parallel 32 km away from topside the FPSO. The smaller footprint means less weight, giving room for 15 to 20 more tons of equipment.

Approval for Roxtec
Inspection, Maintenance

Roxtec Services AB has been audited by Lloyd’s Register and has received an official approval for inspection and maintenance services of cable and pipe transits. Roxtec Services AB is part of cable and pipe sealing solution provider Roxtec Group. The company offers services for the marine and offshore industries, including on-site inspections, repair recommendations, supervision and maintenance work concerning cable and pipe transits on ships and offshore units.

ITF Seeks Participants
For Pipeline JIP

The Industry Technology Facilitator (ITF) is welcoming additional participants to a new joint industry project (JIP) to develop pipeline anchoring and monitoring systems to mitigate the risk of pipeline walking and cut pipeline anchor installation costs in half.

Pipe-walking, or axial ratcheting, has been observed on a number of pipelines and can cause integrity concerns. In some cases, this has resulted in tie-in connector failures or subsea intervention to mitigate or control high rates of walking.

The Anchoring Pipeline Technology (APT) JIP currently involves Shell. The initial phase of the project will run for eight months and will bring together major global operators and pipeline installation companies to collaborate with ITF and Crondall Energy, an independent oil and gas consultancy. It aims to investigate alternative and less costly solutions and create a roadmap on how to manage and mitigate the pipe-walking challenge.

The potential overall savings from the deployment of optimized distributed anchoring systems is expected to be up to 50 percent of a typical installed cost.
