NTSB Recommends Pipeline Operators Implement Safety Management Systems
Safety Board (NTSB) is recommending new notification alarms and procedures for potential incursions on pipelines and a change to an anchorage off the California coast following a crude oil release in 2021 caused by ship anchors damaging an underwater pipeline.NTSB investigators determined that the oil leak, which began on October 1, 2021, in San Pedro Bay, resulted from an anchor strike on the pipeline that occurred eight months earlier, when anchors from the containerships Beijing and MSC Danit dragged and contacted the pipeline during high winds and seas caused by a cold front. The proximity of

a restricted area and dragged a Pertamina pipeline causing it to burst. In Port O’Connor, Texas, a dredge caught on fire after hitting a subsea gas pipeline, and in the Straits of Mackinac, on The Great Lakes, a dragging anchor dented a major pipeline and damaged electric cables causing a mineral oil leak.On December 23, 2019, Malta lost power for 3 hours after a vessel’s anchor cut a power line to the country. The cost of repair and mitigation is estimated to be over 20 million euros.As recently as January 9, 2020, 14 countries in West Africa experienced massive telecom disruption when the
Hydrex Response Repairs Stern in Record Time
the flow of lubricating oil from the stern, but the Port would not let the ship continue on her schedule before a dive team had inspected the propeller shaft seals. At the request of the shipowner, Antwerp-based Hydrex mobilized a dive team which found the temporary fix had not completely stopped the oil leak. All four stern tube seals needed to be replaced. However, because the vessel had just been fully loaded, trimming the vessel was not an option so the repair had to be carried out in-situ, underwater. Hydrex Production Executive Dave Bleyenberg said: “We have been replacing seals underwater
Four Petrobras Platforms Halt Output Due to Oil Leak
Four Petrobras oil platforms off the northeast coast of Brazil have halted production after a leak of about 7,000 liters of oil was detected coming from a pipeline linking them, a local oil workers union head said on Friday. Brazil's oil regulator, ANP, confirmed the leak in the Camorim field, 16 kilometers (10 miles) off the coast of the city of Aracajú, and said it had already been contained by Petrobras. The director of the Sindipetro oil workers union for Alagoas/Sergipe Basin, Stoessel Chagas, said the leak was detected coming from a pipeline linking the PCM-5 and PCM-6
Sunken WW II Ship Oil Leak Plugged
Atlantic Coast Marine Group, Inc. successfully responds to World War II era motor tanker leaking massive cargo of oil into the Atlantic Ocean's waters. Beaufort, North Carolina-based Atlantic Coast Marine Group, Inc. (ACMG), a marine salvage, emergency towing and environmental services provider, was recently contracted to provide an initial survey and fast response pollution mitigation to a World War II era vessel believed to be the SS W.E. Hutton. As ACMG explained, motor tanker W.E. Hutton was underway in 1942 from Texas to Pennsylvania with a cargo of 65,000 barrels of oil when it was sunk

drydock-like conditions was created. This is essential for any permanent seal replacement. The divers removed the first seal and replaced it with a new one which was then bonded. This procedure was repeated with the other two damaged seals. All seals showed cuts at the underside, which had caused the oil leak. The operation ended with succesful leakage tests, the reinstallation of the rope guard and the removal of the flexible mobdocks. During the operation representatives of both the manufacturer of the shaft seals and the bow thruster OEM were present. They followed the operation and gave their
"Soil Shift" Shuts Down Statoil Snorre B Platform
Statoil shut oil production at its Snorre B platform in the North Sea and evacuated a quarter of the personnel there after detecting a soil shift under a drilling template and then oil leak, the company said on Monday. The Snorre field in the northern part of the North Sea is Norway's fourth-biggest oil producer with output averaging 88,000 barrels of oil per day in 2013, data from Norwegian Petroleum Directorate (NPD) showed. The field has two production platforms but Statoil declined to provide a breakdown between Snorre B and Snorre A, which is operating normally. Production at Snorre B
Hydrex Divers Perform Underwater Repair
A Hydrex diver/technician team carried out underwater stern tube seal repairs on a 157-meter dredger in Montevideo, Uruguay in April. The ship was suffering from an oil leak, making an on-site repair necessary. Using a Hydrex flexible mobdock the team was able to carry out the entire operation on-site and underwater, saving the owner an expensive and time-consuming trip to drydock. Hydrex has carried out on-site, underwater repairs and replacements on all types of seals for a number of years now. A dry environment is created underwater in which the divers can work. Several major classification
Hydrex Performs Underwater Repair in Trinidad
Last month a Hydrex diver/technician team carried out underwater stern tube seal repairs on a 148-meter container vessel in Port of Spain, Trinidad. The ship was suffering from an oil leak, making an on-site repair necessary. Using one of the company’s flexible mobdocks the team was able to carry out the entire operation onsite and underwater, saving the owner an expensive and time-consuming trip to drydock, Hydrex said. Every Hydrex office has a fast response center, equipped with all the latest facilities, equipment and tools. These centers were designed specifically to increase speed of
