The elite saturation divers of the Navy, set a new national record for the deepest ocean dive when they dived to 257 meters on 9th January in the Arabian Sea about 35 nautical miles off Kochi.
The Divers from INS Nireekshak – Lieutenant Malkeet Singh, Mukesh Kumar Leading Seaman, BS Bora Leading Seaman, Rithesh Kumar Leading Seaman, M Kumar Leading Seaman and Satender Sharma Leading Seaman exited on 19th January from the Diving Compression Chamber in the presence of their Commanding Officer, shipmates and their families. The divers, who were ensconced in the Deck Decompression Chamber (DCC) since 7th January in preparation for the dive, were decompressed in the DCC on completion of the record breaking dive. Earlier, divers from the same ship had dived to 233 meters in February 2011.
Saturation dive is a highly technical and niche field which helps in providing longer duration dives at deeper depths to carry out specific operations like submarine rescue or salvage. It involves complex support systems from the Diving Support Vessel to enable the divers to explore the final frontiers in physical and mental endurance. Water pressure increases by 1 kg/cm2 on increasing of depth by 10 meters each time. Other complications of deep dives include physiological problems of bubbles formed by gas throughout the body causing “decompression sickness” as the divers come up to water surface. Saturation divers inhale a mixture of helium and oxygen gases under pressure which is prepared and monitored by a team of specialists from the control station. The divers after being compressed to the required depth in the DCC are transferred under pressure to the diving bell through a tunnel arrangement. The Diving bell with the divers is then lowered into the sea. The divers are provided heated gas for breathing and hot water for maintaining body temperatures at those depths where it is pitch dark.
Commander Sandeep S Sarna, Commanding Officer of INS Nireekshak expressed satisfaction and pride at the achievement of his men saying that such endeavours at testing the frontiers provides them greater confidence for future operations. INS Nireekshak had recently participated in a submarine rescue exercise with the US Navy. The ship was also deployed to raise the fishing boat Don I which had sunk off the Kerala coast last year after a collision with a merchant ship.

Hallin Marine has confirmed that its offshore support vessel Penrith sunk last week off the coast of Myanmar. In an e-mail sent to Offshore Energy Today, the company informed that all 42 crew members were rescued.
Hallin said that there were no injuries to personnel other than two minor first-aid cases caused by the initial impact.
“All safety procedures were implemented following the incident, our Emergency Response team is on site and will remain so until the situation has stabilised. We are convening an internal enquiry with the assistance of third-party specialists to establish exactly what happened,” the company said.
“Notwithstanding the fact that the inquiry is still in progress to determine the full facts, it initially appears that Penrith hit a rock while traveling at 10 knots offshore Myanmar.”

A fire occurred on an offshore oil and natural gas platform in West Delta Block 32 in the Gulf of Mexico Friday injuring several people, reported Houston’s KHOU TV, citing the U.S. Coast Guard. The fire has been extinguished.
According to the news station, four people were airlifted to a nearby hospital and were in critical condition. Two more people are said to be missing following the tragedy on the platform – operated by Houston-based and privately-owned Black Elk Energy Co.
Black Elk did not respond to requests for comment.
The Coast Guard has reported that production was not flowing from the well and at least 26 to 28 people had been aboard the platform. The workers were cutting into a line on the platform when sparks from a torch hit a storage tank, which then exploded, resulting in a two-by-a-quarter mile oil sheen around the site. The platform is located around 17 miles offshore Grand Isle, Louisiana in 21 feet of water.
The Coast Guard has activated a “command center” to investigate the incident, consisting of two helicopter teams, one from Mobile, Alabama and one from New Orleans to help with the search, reported KHOU. The government agency also called in two small boat stations out of Grand Isle and Venice to assist.
Black Elk hasn’t filed a recent work permit or exploration plan for that block. The most recent plan filed for the block WD 32 was Aug. 30, 2010 for Maritech to remove platform Caisson 3.

A collision that killed five sailors and sank the Baltic Ace car carrier on Wednesday evening was probably caused by a human error, Reuters informs citing Panagiootis Kakoliris, operations manager at Stamco Ship Management Co., Ltd. which managed the sunken ship.
The weather conditions were normal at the time of the collision, according to Dutch Defence Ministry and Greek manager. Mr. Kakoliris also excluded the possibility of a technical failure of the car carrier indicating that Baltic Ace was just five years old and that it had past the inspection in August.
The Dutch coastguard have located the wreck some 25-30 metres near the Noord Hinder shipping route.
Since the sinking lasted only 15 minutes it is assumed that the Baltic Ace was hit in the side and because of that a large amount of water entered the ship so fast.
The Corvus J owner, a German shipping company Juengerhans has offered its full cooperation into the investigation, but it did not comment or indicate a possible cause of the collision.
Due to bad weather conditions the chance of finding any of the six missing sailors are very slim, the Dutch coastguard said.

East Africa seen as new frontier for gas
Johannesburg - East Africa has emerged as the new frontier for natural gas production, boosted by offshore discoveries in Mozambique, Tanzania and Madagascar, an Ernst & Young report said on Tuesday.
According to the audit firm's report, "the most dynamic recent developments in the African natural gas sector have been in East Africa," despite most of the major players coming from further north.
In the last five years, energy firms including Italy's ENI and US group Anadarko Petroleum have reported several large-scale offshore gas finds in northern Mozambique's Rovuma basin and Mamba fields.
Recoverable gas reserves in Rovuma is estimated at three trillion cubic meters, the report said.
Leading global oil groups are getting in on the act as discoveries in Madagascar and Kenya have upped the ante.
In Tanzania, BG Group, Ophir Energy, Statoil and ExxonMobil have all found "major gas deposits."
The report described east Africa as the "next epicentre" for global natural gas, something which was "non-story" ten years ago.
"With the huge recent discoveries in offshore East Africa (in particular, Mozambique and Tanzania), the future of African gas is, however, expected to shift eastward," said the report.
Gas production in Africa since 2000 has been growing by about 4% per year, with exports destined for the Asian market.
"African gas production reached about 203 bcm (billion cubic metres) in 2011, with production led by Algeria, Egypt and Nigeria, collectively accounting for more than 88% of the continent's total," it said.
The report also noted untapped shale gas resources in South Africa which have been the subject of a controversial debate.
Environmentalists opposed exploration in the vast semi-arid region of Karoo, in the northern Cape, prompting the government to impose a moratorium on the technique known as fracking. The freeze was lifted last month however.
According to consultants Wood Mackenzie, the ease of access to Asian markets and a break-even point that is substantially lower than rival Australia could help natural gas exports.

Experts from joint integrity and engineering services company Hydratight found an innovative solution to a tricky repair for Statoil, by using a MORGRIP connector to repair a 6in super duplex pipe located within the constrained space of a subsea manifold, 340m under the surface of the North Sea.
Hydratight was called in to repair a damaged pipe on a subsea wellhead “Christmas tree” on the Troll C oil and gas platform, 100km north-west of Bergen, Norway.
A mandrel and its 6in supporting pipe were pulled out of position during an operation, overloading the pipe and forcing the shut-down of an associated 10in line, halting production.
“At that depth solutions were limited,” said Hydratight application engineer Mark Fisher.
A 6in super duplex MORGRIP end-connector had to be a specially engineered solution to fit within the significant physical constraints of the damaged manifold.
“The cracked pipe was partially inside the manifold, so we had to ensure that the MORGRIP’S overall dimensions were an absolute minimum to get it to fit,” explained Mark.
The pipe – which carries a mixture of water, oil and gas – was pressure-tested to 267bar after the procedure, and will be tested again from time to time to make sure the pipe hasn’t deteriorated further.
The MORGRIP successfully sealed the line in accordance with Statoil’s requirements. The pipe integrity was retained with no de-rating of the pipeline or deviation from original design.

LAGOS - Gunmen attacked a barge belonging to an oil services company off the coast of Nigeria on Saturday, killing two Nigerian sailors and kidnapping four foreigners, officials said.
The suspected sea pirates stormed the vessel in the Gulf of Guinea, an area that has seen a sharp spike in the number of reported marine attacks over the last six months. A spokeswoman for Sea Trucks Group, which provides support vessels to oil companies operating in Nigeria, told AFP that one of the company’s ships came under fire and that the firm’s employees were taken in the raid. “At this time Sea Trucks Group is making every effort to ascertain the whereabouts of its personnel,” the spokeswoman, Corrie van Kessel, told AFP.
Nigeria’s navy spokesman Commodore Kabir Aliyu said during the attack “four expatriates are reported to have been kidnapped from the vessel; two sailors were killed.”
He said those kidnapped were from Indonesia, Iran, Malaysia and Thailand. The attack, which also left two other seamen injured, took place at roughly 0100 on Saturday, 35 nautical miles off Nigeria’s oil-rich Niger Delta coastal area, the navy and company said.
Aliyu told AFP that the motive of the attack had not yet been established and that so far there has not been any communication with the gunmen.
The volatile area was for years crippled by armed insurgency, largely made up of militants from the Delta who claimed that the region’s people were not benefitting from its vast oil wealth, while crude production devastated the environment.
Armed groups in the Delta were notorious for kidnapping oil workers. A 2009 amnesty deal greatly reduced the unrest, but sporadic incidents have continued to occur including robberies and, most prominently, piracy.
The International Maritime Bureau (IMB) said in a report released last month that there had been 32 piracy incidents recorded in the Gulf of Guinea in the first half of 2012, up from the 25 attacks in 2011.
Many of the raids have involved “high levels of violence,” kidnappings, and were increasingly occurring further offshore, the report added. An IMB official said attacks in the area have been under-reported for several years.
On July 27, suspected sea pirates attacked a vessel transporting workers for Italian firm Agip in the Delta’s Bayelsa state, leaving at least one person dead.
Aliyu told AFP that six naval personnel were stationed on board the Sea Trucks Group vessel following a security request from the company.
Van Kessel explained that Sea Trucks Group is heavily involved in the oil and gas sector in the Delta, but declined to comment on the specific activities of the fired-on ship.
She further said that two of the company’s vessels came under attack, although the navy insisted only one ship was involved. Sea Trucks Group, which also operates in Australia and East Asia, was founded as a Nigerian firm in 1977 before expanding and currently has a “corporate support office” in the Netherlands, according to its website.
Years of unrest in the Delta had curbed oil production in Nigeria, Africa’s top oil producer and the world’s eighth largest, but output has recovered since the amnesty.
On Friday, Nigeria said oil production had hit its highest level ever, reaching 2.7 million barrels per day.

Epic divers and marine has cut beginner saturation rates from 750 and day to 450 a day, and has also lowered its entry level wages for tenders from 16 and hour to 14 an hour, but surely havent cut there rates for clients. This is pretty sad these wages are only obtained by being offshore in which the company is making the same amount of money but they believe since it is so slow in the industry that they can lower the pay standards of the diving industry. These problems are also partly to blame on the younger generation and or inexperianced workers we bring into this industry that will do the same job for less everytime one of us settles for less we are cutting our own throughts.
this was not the first straw companies cut safety, incentive, and retierment programs across the board everyone was upset but when the phone rings everyone is eager to go to work at some point the risk will not be worth the reward and hopefully employees will stand together agaist these type of disrespectfull cuts no diving personnel in the GOM available and able to work the entire year should be making under $60,000.00 a year

Be very aware of a Nigerian scams offering Job Opportunities for mainly senior personnel like Client Reps. They are very Good and must have integral knowledge of the business or even be on the inside. The are using Shell, Chevron, Nigerian Immigration and Nicon Insurance names to make it look very legit. They are also using Agip Oil and are coming from a UK based Engineering company , yes very professional so look out for this.

Additional Items for Contractors and Operators to Consider
Recent events in the Gulf of Mexico have forced all industry stakeholders to reevaluate how they approach operations, as a result of the Deepwater Horizon Spill. For Diving Contractors, this means devoting greater attention to:
· Evaluation of site plans for dealing with a contaminated diver
· Evaluation of whether 5 minute surface intervals can be met, if diving Sur 'D' O2
· Possibly limiting dives to "No Decompression"
· Reinforcement to personnel of their "Stop Work" authority
· The need for hydrocarbon monitors in saturation diving bells
· Need for a dedicated decontamination / wash down station on vessels for surfacing divers
Additionally, certain waterways that have been normally available to vessels and mariners are now restricted. This has increased vessel traffic, as fisherman and other boaters now look for new and accessible areas. This translates into an increased risk of vessel encroachments. As such, contractors are encouraged to stay vigilant in their monitoring of vessel traffic, when conducting underwater operations. There are several web sites which outline areas that vessels are encouraged to avoid, and track the spread of the oil spill.
Another new dynamic for industry personnel to take note of is the increased presence of personnel, enlisted to aid in the spill response and cleanup. Many of these individuals (new employees or volunteers) are not familiar with offshore safe practices and operations. This is probably most prevalent at the ports throughout the Gulf coast that have been dedicated to deploy personnel for spill cleanup.
In short, the items mentioned above are just a snapshot of the different challenges facing contractors and operators. There is much going on in the Gulf of Mexico, which will require a greater level of attention to detail by all.
This Information was sent to further the communication of all industry stakeholders. Safety is the primary concern of the ADCI. Remember: a real-time Job Safety Analysis is important, but nothing can replace good common sense.
