A diving support vessel is a ship that is used as a floating base for professional diving projects.^[1]

• 1History

History[edit]

Commercial Diving Support Vessels emerged during the 1960s and 1970s, when the need arose for offshore diving operations to be performed below and around oil production platforms and associated installations in open water in the North Sea and Gulf of Mexico. Until that point, most diving operations were from mobile oil drilling platforms, pipe-lay, or crane barges. The diving system tended to be modularised and craned on and off the vessels as a package.^{[citation needed]}

As permanent oil and gas production platforms emerged, the owners and operators were not keen to give over valuable deck space to diving systems because after they came on-line the expectation of continuing diving operations was low.^{[citation needed]}

However, equipment fails or gets damaged, and there was a regular if not continuous need for diving operations in and around oil fields. The solution was to put diving packages on ships. Initially these tended to be oilfield supply ships or fishing vessels; however, keeping this kind of ship 'on station', particularly during uncertain weather, made the diving dangerous, problematic and seasonal. Furthermore, seabed operations usually entailed the raising and lowering of heavy equipment, and most such vessels were not equipped for this task.^{[citation needed]}

This is when the dedicated commercial diving support vessel emerged. These were often built from scratch or heavily converted pipe carriers or other utility ships. The key components of the diving support vessel are:

• Dynamic Positioning - Controlled by a computer with input from position reference systems (DGPS, Transponders, Light Taut Wires or RadaScan), it will maintain the ships position over a dive site by using multi-directional thrusters, other sensors would compensate for swell, tide and prevailing wind.
• Saturation diving system - For diving operations below 50m, a mixture of helium and oxygen (heliox) is required to eliminate the narcotic effect of nitrogen under pressure. For extended diving operations at depth, saturation diving is the preferred approach. A saturation system would be installed within the ship. A diving bell^[2] would transport the divers between the saturation system and the work site lowered through a 'moon pool' in the bottom of the ship, usually with a support structure 'cursor' to support the diving bell through the turbulent waters near the surface. There are a number of support systems for the saturation system on a Diving Support Vessel, usually including a Remotely Operated Vehicle ROV and heavy lifting equipment.

Modern diving support vessels[edit]

Most of the vessels currently in the North Sea have been built in the 1980s. The semi-submersible fleet, the Uncle John and similar, have proven to be too expensive to maintain and too slow to move between fields.^{[citation needed]} Therefore, most existing designs are monohull vessels with either a one or a twin bell dive system. There has been little innovation since the 1980s. However, driven by high oil prices since 2004, the market for subsea developments in the North Sea has grown significantly.^{[citation needed]} This has led to a scarcity of Diving Support Vessels and have driven the price up. Thus, contractors have ordered a number of newbuild vessels which are expected to enter the market in 2008.^{[citation needed]}

These Vessels are built and designed nowadays not only to Support Diving Activities but they also support Remotely Operated Vehicles (ROV's) operations with Dedicated Hangar and LARS for ROV's, Support Seismic Survey Operations, Support Cable Laying Operations, etc. Owing to these nature of the modern day vessels, they may have at any time 80 to 150 Project Personnel onboard including Divers, Diving Supervisors and Superintendents, Dive Technicians, Life Support Technicians and Supervisors, ROV Pilots, ROV Superintendents, Survey Team, Clients Personnel, etc. For all these Personnel to carry out their contracted job with an Oil and Gas Company, a Professional Crew Navigate and Operate the Vessel as per the requirements and instructions of the Diving or ROV or Survey team Superintendents. However, Ultimate responsibility lies on the Master of the Vessel for the Safety of every Personnel onboard. In expanding the Utility of the vessel, just like Liveaboard Dive Boats, these vessels in addition to the usual domestic facilities expected by hotel guests, the vessel will have specialised Mix Gas Diving Compressors and Reclaim systems, Gas Storage and Gas Blending Facilites, as well as purpose built Saturation Chambers where the Divers in compression live. These Vessels are designed to be hired by Diving Service Providing Companies or directly by Oil and Gas Contractors who then will also hire a Diving or ROV or Survey Service Providing Company which will then utilize the Vessel as platform to carry out their activities.

SBM Offshore N.V. (IHC Caland N.V. prior to July 2005) is a Dutch-based global group of companies selling systems and services to the offshore oil and gas industry. Its constituent companies started their offshore activities in the early 1950s and SBM subsequently became a pioneer in single point mooring (SPM) systems.^[2] The firm leases and operates Floating Production Storage and Offloading vessels, and is involved in the design and engineering, the construction, the installation, the operation and the life extension of floating production solutions for the offshore Oils and Gas industry. It is a main board listed company on the Euronext Amsterdam stock exchange and has been a member of the AEX index since 2003. It has been engulfed by a massive corruption scandal in Brazil, where it bribed officials in the state oil company Petrobras in order to secure contracts. SBM Offshore has avoided criminal prosecution in the Netherlands by paying a record settlement of $240 million to the Dutch Public prosecutor 'While in Brazil the Petrobras corruption affair — and SBM Offshore’s major role in it — is inexorably building to a climax, the temperature in Netherlands appears to have dropped after a record settlement was reached with the Dutch Public Prosecutor (OM) in November last year. The biggest corruption case in the Dutch history was bought off by SBM for a record $240 million in exchange for which no court case followed and no admission of guilt was entered. To the OM it was important the company had implemented major reforms to prevent re-offending. 'We are now a white swan in a pitch-black sea,' said a relieved and proud SBM director Sietse Hepkema in an interview with leading Dutch newspaper NRC Handelsblad last December. The man hired to clean up the company said he didn’t expect further fines in Brazil. 'I really think we paid our dues, 'he said. And 'I refuse to be Brazil’s smelly kid in the classroom.'^[3] In order to be able to take part in Petrobras contracts in the future, SBM has also agreed to a R$1 billion settlement with the Brazilian government.^[4] Nevertheless, many of SBM's executives still face criminal charges in Brazil.^[5]

Operations[edit]

The company was the first to offer an integrated oil and gas production service through the investment in a Floating Production Storage and Offloading (FPSO) unit. The lease and operation of FPSOs has become a large component of the company's activity and SBM Offshore now owns and operates the world's largest fleet.^[6] Other activities include design and engineering, turnkey supply, and specialised services such as maintenance and offshore installation. The most recent addition to the product line is midscale LNG (liquefied natural gas) FPSOs for a capacity in the range of 1 and 2 MTPA (Million Tonne Per Annum) with Nitrogen expansion liquefaction technology, developed in collaboration with The Linde Group.^[7]

The firm operates from five main execution centres: the global headquarters in Schiedam, Monaco, Kuala Lumpur, Houston and Brazil. The company employs over 8,000 individuals worldwide.

On 18 August 2009, SBM Offshore announced the signing of a framework agreement with Shell for the supply of turret mooring systems for Shell's floating liquified natural gas (FLNG) project. The deal covers the supply of turret mooring systems for a period of up to 15 years. The 3.5-million-tonne-per-annum FLNG facility will produce liquefied natural gas offshore and will be moored with an internal and permanently connected freely weather-vaning turret mooring system. SBM Offshore said the turret mooring system is expected to be the largest in terms of diameter with capability to handle mooring loads in excess of current systems.
