CHC Wins Contract with Providence Resources PLC

CHC Group (the "Company" or "CHC") today announced it has signed a new contract with Providence Resources plc ("Providence") to provide helicopter services in support of its Exploration well program on the Druid/Drombeg prospect in Frontier Exploration Licence 2/14 of the southern Porcupine Basin, Offshore Ireland, some 215 kilometers off the southwest coast of Ireland. The contract will see a dedicated Sikorsky S-92 flying out of Cork Airport beginning this June and will once again see CHC work in conjunction with Lloyd’s Register ("LR") as the wells project management company."We are delighted that Providence and LR have, once again, selected CHC as its aviation partner," said Mark Abbey, CHC Regional Director for Europe, Middle East and Africa (EMEA). "With our extensive experience transporting offshore workers in the oil and gas industry, dedication to safety, and reputation for the highest quality service, we look forward to building on our relationship with the Providence team in Ireland,""This is a great continuation of our relationship with both Providence and LR," added Karl Fessenden, President and CEO of CHC Helicopter. "We look forward to supporting this operation and providing the global standards for safety, logistical support and efficiency that customers around the world expect from CHC."

Licence Update Frontier Exploration Licence 2/14 Southern Porcupine Basin

Providence Resources P.l.c. (PVR LN, PRP ID), the Irish based Oil and Gas Exploration Company, provides an update on the Frontier Exploration Licence (”FEL”) 2/14, which lies in c. 2,250 metre water depth in the southern Porcupine Basin and is located c. 220 kilometres off the south west coast of Ireland. The licence is operated by Providence Resources P.l.c. (“Providence”, 80%) on behalf of its partner Sosina Exploration Limited (“Sosina”, 20%), who are collectively referred to the “JV Partners”. FEL 2/14 contains the Paleocene “Druid” and the Lower Cretaceous “Drombeg” exploration prospects. The Minister of State for the Department of Communications, Climate Action and Environment has given his consent to the progression to the second phase of the licence, subject to the completion of the agreed work programme which includes the drilling of the 53/6-A exploration well on the Paleocene Druid prospect and the subsequent integration of the well data into a comprehensive assessment of the petroleum potential of the licence. In November 2016, the Company signed a drilling contract for the provision of the Stena IceMAX drill-ship to drill an exploration well in FEL 2/14 during 2017. The drilling contract provides for one firm well, plus an additional option, which is electable at the discretion of the JV Partners for the drilling of a second follow -on well. Other key service contracts are now being finalized for the drilling operations for the planned 53/6-A exploration well. Based on the latest project timeline and, subject to standard regulatory approvals and consents, the 53/6-A exploration well is currently planned to spud in June 2017.

CNSOPB permits resumption of drilling with conditions

The Canada-Nova Scotia Offshore Petroleum Board (CNSOPB) today permitted Shell Canada to resume drilling with restrictions at its Cheshire L-97 exploration well. Drilling was halted on March 5th after an operations incident on the Stena IceMAX drillship. After securing the exploration well with two barriers and successfully disconnecting to ride out heavy weather, the riser was accidentally dropped to the seafloor. No one was injured and no well fluids or synthetic oil-based drilling fluids were spilled to the environment. The CNSOPB review confirmed that the crew of the Stena IceMAX appropriately prepared for heavy weather in the days leading up to the incident on March 5th by suspending drilling, installing two barriers to secure the well (a downhole plug and the closing of the Blowout Preventer, BOP), and displacing drilling fluids in the riser to sea water. When vessel motion exceeded the operational limits, the decision was made to disconnect and ride out the weather with the riser attached to the vessel through the tensioner riser system, a standard procedure. To maximize the distance between the bottom of the riser and the BOP so as to protect the integrity of the well, the tensioner system holding the riser was fully retracted. The key factors in the cause of the incident were the heave of the vessel andthe inability of the riser tensioner system to compensate for the difference in the movement between the riser and the vessel with the tensioner system in a fully retracted position and with the Riser Anti-Recoil System (RARS) inactive. For the past three months the CNSOPB has thoroughly reviewed the incident and investigation report. It engaged independent, outside, world-class expertise in deep-water drilling to provide additional oversight. Aberdeen Drilling Management (ADM) worked with the CNSOPB in the review of the incident, the work procedures, the investigation report and an assurance plan that CNSOPB required from Shell Canada, to determine whether drilling can be safely resumed, and, if so, under what conditions. “This has been a rigorous and exhaustive review of the incident,” says CNSOPB CEO Stuart Pinks. “We are satisfied that the cause of the incident has been properly determined and that appropriate corrective actions have been taken so that drilling may resume safely. As an additional safeguard, the CNSOPB has introduced a condition further tightening operating limits under which drilling may occur.” Until such time as the CNSOPB completes further reviews, Shell Canada is required to lower its well disconnect criteria on the Stena IceMax based on vessel heave of five metres. The previous criteria was eight metres. Before permitting a return to drilling the CNSOPB sought and received assurance on a number of matters arising from the review of the incident and the investigation report. These included: Equipment – That all repaired and replacement equipment is certified, installed, commissioned, tested and compliant. Procedures – That procedures and operational criteria are reviewed and amended, where applicable, with specific focus on updated disconnect procedures and the use of weather forecasting. Training and competency – That people are trained and fully aware of changes to procedures, their roles and responsibilities, and are specifically aware of weather related disconnect criteria. In addition, disconnect drills and simulations are conducted to ensure that personnel in positions critical to the disconnect process are fully conversant with revised procedures. Risk Management – That a review of the incident investigation findings and learnings related to equipment, work procedures, and personnel competency be conducted to ensure risks are ALARP (as low as reasonably practicable). Pinks says the CNSOPB continues to review the incident, including the investigation report, to determine if future regulatory actions or changes are required. No decisions have yet been made with respect to the riser that remains on the seafloor.

Fairmount Fuji Assisted Stena Icemax

Fairmount Marine’s multipurpose support vessel Fairmount Fuji has assisted drill ship Stena Icemax while making a stop-over at Cape Town. On request of the owner of Stena Icemax the Fairmount Fuji carried out several cargo runs from the port of Cape Town to the anchorage. Stena Icemax was under way from the Far East to French Guiana and required to make a stop-over at Cape Town for crew change and replenishment. Stena Icemax is a 228 meters long new build drill ship designed for deep water operations in harsh environments. Fairmount Fuji is a multipurpose support vessel with a spacious aft deck of 280 square meters and with towing capabilities. Directly after assisting Stena Icemax the Fairmount Fuji was prepared for her next assignment in West Africa region, where she will act as an accommodation and general support vessel for an offshore operator.
