Seadrill defers delivery of two drillships from DSME

Seadrill Limited announced on Friday (Jan 15) that an agreement with DSME shipyard has been reached to
defer the delivery of two ultra-deepwater drillships, the West Aquila and West Libra,
until the second quarter of 2018 and first quarter of 2019 respectively.

Under the terms of the original construction contracts, the units were to be delivered by the end of the second quarter
of 2016 and the total final yard instalment for both units of over $800 million was due at that time.

This agreement significantly improves the Company's near term liquidity position by deferring these
capex commitments to 2018 and 2019 with no further payments to the yard until that time.

This information is subject of the disclosure requirements pursuant to section 5-12 of the Norwegian Securities Trading Act.

Bibby Marine Services orders first-ever Damen Service Operations Vessel

On 15 January, Bibby Marine Services Limited, part of Bibby Line Group, signed a contract with the Damen Shipyards Group for delivery of its first Service Operations Vessel (SOV) with walk-to-work access. The vessel, Bibby WaveMaster 1, will undertake offshore wind project work in the North Sea. It is the first vessel purpose-built for the transfer and accommodation of offshore personnel and aims to maximise working time and staff retention. The design guarantees fast, safe and comfortable access to turbines, at lower cost, up to 80% of the time, including in worst case scenario Central North Sea conditions, resulting in a vessel capable of providing access up to 3.1 metre Hs.

In line with wind farms being constructed farther from shore, the SOV with walk-to-work access is able to remain at sea for periods up to one month. Accommodation is provided on board for up to 45 turbine maintenance personnel and 15 crew members.

Damen Business Development Manager Peter Robert described the thinking behind the concept, saying:

“This is much more than just a vessel – it is a total access and accommodation solution. The development of this vessel has started with a blank sheet of paper, as opposed to being an evolved version of an existing design. It has been tailored specifically to the needs of the offshore wind industry. This is the first time that a wind farm operations and maintenance vessel has been designed exclusively for this purpose. Great care has been taken, over 2 years of development, to ensure suitability to the tasks for which it is designed.

“As a result, the vessel will ensure the safety and comfort of all on board for increased workability. This, in combination with other design features aiming at optimal workflow, ensures that the Service Operations Vessel offers a revolutionary performance in terms of cost-efficiency."

The attention to detail can be seen throughout the design. For example, the hull, at 90 metres, is longer than that of a conventional platform supply vessel and the bow section has been lowered by 1.5 metres to create a V-shape. This feature offers significantly reduced slamming and facilitates inclusion and improved offshore operation of the bow thrusters.

The aft ship has been adapted specifically to the tasks that the vessel is designed for, including stern to waves operations. The most pronounced features that have been included are the strong V-shape in the frames in the aft ship to reduce the slamming occurrence and loads and the concentration of volume in the mid-ship region to achieve a slender aft ship. Both features should make stern to weather operations more comfortable than on a common PSV design.

Comfort onboard stems also from ergonomic design application, which sees interior spaces grouped together into similar task areas. This not only separates ‘clean’ and ‘dirty’ tasks, but ensures short lines of communication and smooth workflow. The accommodation has been placed midships for additional comfort – the location reducing vertical acceleration by as much as 15%.

Efficiency is another key feature. The design includes a diesel-electric main propulsion system, which powers twin azimuth thrusters. Thanks to careful development, the vessel requires less installed power than a conventional PSV. This results from two factors – a symmetrical wind profile and use of a four split main switchboard.

Mr Robert: “The symmetric profile is created by locating the superstructure amidships instead of bow mounted. Because of this, the wind induced moment is less, resulting in lower required bow thruster power. The four split configuration of the main switchboard enables us to divide the generator sets more efficiently than in conventional arrangements with two switchboards. In the event of a failure only one of four switchboards would be out of action, as opposed to one of two. That leaves proportionally more power available, again requiring less total installed power.”

A high-performance, motion-compensated access gangway and active heave compensated crane are located to port side, close to the centre of gravity. The management systems of both features are aligned with the vessel’s DP system.

Proven to Master the weather

The DP capabilities have already been proven, with a first-of-its-kind scale model test at the Netherlands-based leading research institute, MARIN. During these tests, the scale model of the vessel was pitted against North Sea wind, wave, swell and current simulations.

The target was a 30-minute cycle, during which the vessel deploys the gangway and then transits in AutoTrack mode, several hundred metres, at speeds up to and beyond 6 knots to the following turbine without having to wait for an ideal weather window or having to rebuild the DP model at every turbine.

Flexible & versatile

The vessel will be used by Bibby Marine Services to serve the offshore wind industry although the design can just as easily be applied to the offshore oil and gas sectors.

A host of options are available for the vessel, including an additional deck crane with up to 24 tonnes capability, tanks arrangements suited to liquids such as glycols, tanks suited to low flashpoint liquids with separate delivery intakes and facilities for dive support and ROV operations.

Nou ja Ron, als je nagaat dat Zapata 'm in 1976 of daaromtrent in gebruik heeft genomen heeft ie toch bijna 40 jaar dienst gedaan. Niet verkeerd voor spul wat heel rap veroudert, want in diezelfde tijd zijn de technieken en inzichten wel iets veranderd. Goed, hij heeft ook wel (een paar keer?) een upgrade gehad, maar toch. Wie weet gebruik ik ooit nog Zapata Semac-1 scheermesjes :mrgreen:

Aker Solutions Awarded Two MMO Contracts From ConocoPhillips in Norway

Aker Solutions' maintenance, modifications and operations (MMO) business in Norway secured two contracts for work at North Sea fields
operated by ConocoPhillips.

The company received a framework agreement for a fixed period of five years to become ConocoPhillips' main supplier of maintenance
and modifications work offshore Norway.
The agreement may be extended by up to three years and covers work on all installations at the Ekofisk and Eldfisk fields offshore Norway, starting in February.

The contract value depends on how much maintenance and modifications work is undertaken over the next five years and
could range between NOK 1 billion and NOK 3 billion in that period. The range neither represents a minimum nor a
maximum amount but serves to illustrate a realistic, yet uncertain range.

Aker Solutions was also one of three companies awarded a contract to compete for work on large, complex modifications projects at these fields.
This contract has the same fixed period and option as the framework agreement.

"We're very pleased to secure these two major agreements with ConocoPhillips,
which build on the strengths of our operations in Norway and our expertise in complex modifications
," said Luis Araujo, chief executive officer of Aker Solutions.

Work on both contracts will be managed and executed by Aker Solutions' MMO unit in Stavanger and fabrication yard in Egersund.
The agreements will also provide work for offshore employees.

"The Ekofisk and Eldfisk installations comprise one of the largest maintenance and modifications portfolios offshore Norway
and these contracts will help secure jobs in key parts of our Norwegian MMO business
" said Per Harald Kongelf, head of Aker Solutions' Norwegian operations.

ABB technology to help vessels operate safely 5 kilometers below sea level.

ABB, the leading power and automation technology group, will provide the technology that will help
three vessels safely carry out construction and maintenance tasks up to 5 kilometers underwater.
The vessels will be equipped with ABB’s OCTOPUS software that uses sensors and the Internet of Things,
Services and People (IoTSP) to interpret weather conditions, allowing the crew to make informed decisions during sensitive operations.
The ships will be built for Ultra Deep Solutions at CSIC Huangpu Wuchang Shipbuilding Company Limited and China Merchants Heavy Industry.

The largest vessel’s apparatus will include two remotely operated underwater vessels (ROVs), that will dive up to 3000 meters,
and a 400 ton crane that can drop 5 200 meters. It will measure 142 meters in length.

The OCTOPUS suite of products is a powerful tool that provides onboard decision support and operational advice during
weather-sensitive offshore operations by monitoring and forecasting vessel motions.
When working in deep-water without mooring or anchoring lines,
an important part of the set-up is the OCTOPUS-Operational forecast function.
This extension within OCTOPUS makes it possible to define an optimal operational window during weather sensitive operations on DP.

Juha Koskela, Managing Director of ABB’s Marine and Ports business, said,
“The broad scope of supply we have on these vessels is a demonstration of the wide range of solutions we have to offer the maritime sector.
These vessels will benefit from some of the most established software and hardware technologies in the shipping industry.”

The vessels also will feature ABB generators, motors, drives and switchboards.

Jithu Sukumaran Nair, General Manager of Shipbuilding at Ultradeep Solutions said,
“We are proud to be the first offshore vessel operator in the world to install the OCTOPUS weather monitoring system on board high tech dive vessels”

Global OSV market to remain difficult into 2017: MMA Offshore

The global market for offshore vessels is forecast to stay challenging into 2017,
as operators continue to find it hard to achieve high utilisation and charter rates have fallen significantly in some markets, according to MMA Offshore.

Marine service provider MMA noted that market conditions in the offshore oil and gas industry continue to be difficult with oil prices at 12 year lows.

“The international market for offshore vessels remains very difficult with large numbers of vessels competing for limited work.
Maintaining utilisation remains challenging and rates have now come down by up to 50% in some markets,” said Jeffrey Weber, managing director of MMA.

“The Middle East is holding up slightly better in terms of utilisation and MMA is focused on growing its operations in this region,
” Weber adder.

MMA shared that vessel operators in the Southeast Asian market continue to price at close to breakeven rates to maintain utilisation,
with day rates now approximately 40-50% lower than June 2014 levels.

The Middle East market continues to hold up better with utilisation relatively stable but rates down over 30%.

Fremantle-based MMA owns and operates over 60 OSVs throughout Australia and internationally.
Reduced construction activity in Australia will impact its vessels and supply based businesses and lower activity is expected globally as well.

The tough operating environment has led to MMA posting a net profit of AUD6.46m ($4.67m) in the first half ended 31 December 2015,
down 82.8% from AUD37.71m in the previous corresponding period.

Revenue for its first half of financial year 2016 also fell by 32.2% year-on-year to AUD309.33m.

“At this stage, we anticipate market conditions will remain challenging for the remainder of FY16 and into FY17.
We expect second half earnings to be significantly lower than the first half as a result of reduced Australian construction activity,
the seasonal impact of the Southeast Asian monsoon period and ongoing depressed market conditions,” Weber said.
