The world’s most advanced and largest ultra-deepwater semi-submersible drilling rig has been delivered by China’s Yantai CIMC Raffles Offshore shipyard.

The DP3 rig Bluewhale 1 has an operating depth of up to 12,000 feet (3,658 meters) and a drilling depth to 50,000 feet (15,240 meters), making it capable of drilling in any waters around the world. It is 387 feet (118 meters) high, equal to a 37-story building.

CIMC Raffles says the 42,000 ton vessel uses 10 percent less fuel than comparable rigs.

SeaOwls and Ulstein conceive ballast water free heavylift jack-up concept

Netherlands-based SeaOwls and Norwegian shipyard Ulstein have launched a pioneering heavy lift jack-up vessel design concept, the Soul. The cruciform structural lay-out is claimed to make the patent-pending solution more than 10 per cent lighter than conventional jack-up vessel designs, yet, all loading and installation operations can be performed without the need of ballast water.

In combination with a high capacity crane, the SOUL enables operators to take the next step in developing offshore wind farms. The concept aims to install the next generation wind turbines (10-12 MW) in the same time frame as currently used for installing 6-8 MW units, a significant efficiency gain over any jack-up vessel design currently available in the market.

DNV GL presented its new standard for assessing the station keeping capability of dynamic positioning (DP) vessels at the European Dynamic Positioning Conference which was held in London in February.

The ability to assess and compare the dynamic positioning capability of a ship equipped with DP technology is vital during the planning and design phases, and provides valuable operational decision support. The DNVGL-ST-0111 standard is the first to provide a unified approach to these assessments, ensuring verifiable results and increasing transparency in the market.

Denmark-headquartered coatings specialist Hempel is introducing two new coatings; Hempadur Quattro XO 17820 and 17870.

They are being introduced to increase the service life and reduce on-station maintenance requirements of offshore assets. The new high-performance pure epoxy uni-primers presented are claimed to combine excellent corrosion protection with construction flexibility.

Hempadur Quattro XO 17820 / 17870 are part of a series of two-component epoxy primer coatings which provide advanced crack resistance using Hempel’s patented fibre technology. They can be applied in immersed and non-immersed areas of any offshore asset, from offshore platforms and drilling rigs through to support vessels.

Workers on drilling rigs and offshore wind farms can hopefully look forward to a more pleasant commute to work with considerably lower risk of seasickness thanks to a special, innovative ship built by VEKA Group. VEKA will be building two trimarans intended specifically for transporting personnel and freight to offshore wind farms. These are the first hybrid trimarans in the world. Transporting offshore personnel takes place mainly by catamaran. These will be VEKA’s first trimarans.

Most of the innovations are intended to make the so-called workboat more stable and more comfortable, thereby reducing the risk of seasickness. For example, the ships have lower windows than is customary, so that the passengers have a better view. The third bow is designed to ensure additional stability and comfort. There are also innovative stabilisers built into the hull.

DNV GL reveals the patterns behind incidents and accidents

Learning from failures and incidents is essential in a lean and cost effective organisation and is often a fundamental requirement in regulations. However, incidents should not be seen in isolation as the broader view and key industry learnings might get lost. DNV GL has investigated over 2000 incidents and failures globally, identifying trends among the data and invites the oil and gas industry to join and share experiences. To further strengthen DNV GL’s global lab capabilities for failure investigation, a new lab in Bergen is opening, including one of the world’s largest tensile testing machines.

As the oil and gas industry strives for cost effective execution in projects and operations while maintaining a high focus on safety and environmental footprint, innovative and smart solutions are needed more than ever. By extracting data and knowledge from all the detailed incident investigations performed over the years, solutions might be just around the corner.

Automated Ships Ltd from the UK and Norway’s Kongsberg Maritime have signed a Memorandum of Understanding to build the world’s first unmanned and fully-automated vessel for offshore operations. In January 2017, Automated Ships Ltd will contract the ‘Hrönn’, which will be designed and built in Norway in co-operation with Kongsberg.

Sea trials will take place in Norway’s newly designated automated vessel test bed in the Trondheim fjord and will be conducted under the auspices of DNV GL and the Norwegian Maritime Authority (NMA). The Hrönn will ultimately be classed and flagged, respectively.

BAM International has achieved a worldwide first having been awarded a contract to design, fabricate and install five full-size gravity base foundations for wind turbines off the Northumberland coast in the UK. The contract has been awarded to BAM by EDF Energy Renewables via SPV Blyth Offshore Demonstrator Ltd and utilises leading edge technology, the first of its kind to be built in the world.

The foundation design will utilise ‘self-installing’ technology, which has been developed by two BAM companies, BAM Nuttall and BAM Infra. The design is being undertaken by BAM Infraconsult.

Leading international classification society Bureau Veritas has approved in principle the repair of offshore structures using the bonded composite product Coldshield, developed by Paris based Cold Pad. Coldshield is a composite structural reinforcement specifically developed for the harsh environments of offshore units.

Matthieu de Tugny, Senior Vice-President and Head of Offshore, Bureau Veritas, says, “Coldshield offers a long awaited solution for the repair of corroded offshore structure without the need for welding or downtime. We have combined our expertise in marine composites and bonding with our experience of the hydrodynamic loadings and constraints of offshore units to assess Coldshield. We believe that Coldshield is the first non-welded structural repair method available for an FPSO hull.”

Machinery, what is the underwriter’s problem?

We are haemorrhaging money! Machinery is the biggest cost in terms of overall claims amount that insurers pay. Machinery incidents amount to over 40% of the overall claims paid by underwriters. To give some background, insurers cover the cost of replacing machinery which has broken as a result of negligence by the crew providing such loss or damage has not resulted from want of due diligence by the
insured, owners or managers. This is very wide coverage and effectively acts as warranty insurance for the machinery. Obviously it is open to abuse and insurers trust the owners to be open and honest when presenting a claim for machinery damage.

I have been in the insurance industry for over 30 years and have benefited from the Braemar’s, previously the Salvage Association, monthly reports. The top four causes of casualty are always machinery, grounding, fire and collision in that order. This is also backed up by the International Union of Marine Insurers (IUMI), where the data is kindly provided by Lloyd’s List Intelligence.

The UK Maritime & Coastguard Agency has issued guidance note MGN 543 to highlight issues that need to be taken into consideration when assessing the impact on navigational safety and emergency response (search and rescue, salvage and towing, and counter pollution) caused by offshore renewable energy installation developments. It applies to proposals in United Kingdom internal waters, Territorial Sea and Exclusive Economic Zone.

Offshore Renewable Energy Installations (OREI) include offshore wind farms, tidal energy converters (including tidal range devices), wave energy converters and any associated infrastructure with the potential to affect marine navigation and emergency response, proposed in United Kingdom (UK) internal waters, Territorial Sea and Exclusive Economic Zone (EEZ).
