Groningen gas production falling faster than planned -Dutch gov’t

GRAPHIC DOES NOT APPEAR IN REUTERS ARTICLE

FEBRUARY 8, 2019

AMSTERDAM, Feb 8 (Reuters) – Gas production at the Groningen field in the north of the Netherlands is falling faster than planned, the Dutch government said on Friday.

Output at the field will fall to 15.9 billion cubic metres (bcm) in the year ending October 2020, the government said, which is 1.5 bcm lower than originally planned.

The Dutch government last year said it would end production by 2030 and lower it as quickly as possible in coming years, as decades of extraction have led to a series of damaging earthquakes in the region. read more

Safety strife for Shell’s LNG giant Prelude

The Prelude project will be fired up 475 kilometres north-east of Broome, ready to liquefy natural gas straight from the ocean floor and ship it around the world.

Peter Milne: The West Australian: 

Shell has struggled through a series of safety missteps as it readies its cutting-edge Prelude floating LNG vessel for production.

Shell reported 17 incidents to the offshore safety regulator NOPSEMA between May and October 2018 that the regulator classified as dangerous occurrences.

The reports, obtained by WestBusiness through a freedom of information request, show the challenges facing hundreds of WA workers that have helicoptered about 500km back and forth between Broome and the 488m-long giant since it arrived from South Korea in July 2017.

One difficulty with floating LNG vessels is that an LNG carrier must berth alongside as the two vessels bob about in the sea, unlike floating oil production facilities that offload oil to a tanker a safe distance away through long flexible hoses.

In early May 2018 Shell tried to bring the LNG carrier Gallina alongside.

A tow rope to a tug failed when the 290m-long carrier was just 50m from Prelude and the operation had to be aborted.

That problem was caused by a tow rope that was incorrectly assembled.

Nine days later something as trivial as wrongly shaped plastic thwarted another attempt to load LNG on to Prelude.

It was thought the Gallina was safely secured to the Prelude by 16 mooring lines that ran through guides on the Prelude called fairleads. As the crew prepared to connect the LNG loading arms a mooring line failed and the Gallina was released and pulled away.

Afterwards it was found that all 16 lines had been significantly damaged by rubbing against sharp edges of nylon liners in the fairleads.

This seemingly trifling detail could have caused a “complete mooring failure” with “potential for serious consequences” if it had occurred later while LNG was being transferred.

Two weeks later the Gallina successfully offloaded its LNG and Prelude had gas to power itself and test its processing plant.

However, having gas on board the Prelude increased the risks Shell had to manage.

A flange leaked near the LNG loading arms as super-cold -162C LNG sitting at the bottom of a pipe caused it to contract and bend.

Another type of gas, hydrogen sulphide, was released when construction debris from the Korean shipyard was being removed from a tank and the area was evacuated.

In July a fire damper intended to keep gas from entering the air-conditioning system for the accommodation quarters failed to close when tested but was repaired quickly.

In August, Prelude lost all its power supply when a pump sending water to a gas-fired boiler tripped.

All workers on the Prelude and the attached 750-bed Posh Arcadia floating hotel went to their muster stations as the diesel emergency generators powered up to supply essential services.

But a transformer failed and the system to cover the deck with firefighting foam was left without power and unable to operate.

Other problems included a test of a system to cover the top of LNG tanks with a deluge of water in an emergency that found it delivered only half the planned amount of water as the system used undersized valves.

There was a small fire when dust in an oxygen cylinder valve ignited, leading to a muster of all personnel.

Newly installed insulation on a hot high-pressure steam line was seen smouldering and when the insulation was pulled away it caught fire. The insulation had been secured by combustible tape.

A Shell spokeswoman said the company had a rigorous program on Prelude to identify and manage risk in a controlled way.

“It is not unexpected for issues to arise during this phase of a project and it is standard practice to notify NOPSEMA,” she said. “We are proud of our safety and reporting culture.”

She said Shell encouraged workers to raise safety concerns.

TEETHING PROBLEMS

2017

July: Prelude arrives from Korea

2018

May: Tow line to tug fails, mooring lines fail

June: LNG loaded onto Prelude, gas leak, flood detection not working

July: Hydrogen sulfide leak, flooded machinery room, fire dampers did not close

August: No power to fire-fighting foam

September: Smouldering insulation

October: Small fire

December: 750-bed accommodation vessel for additional workers leaves, wells opened and gas flows to Prelude.

2019

February: Preparing for first export of condensate

Shell deal ‘huge step’ for Cluff’s North Sea growth, says CEO

Written by

The chief executive of Cluff Natural Resources (CLNR) has said the company’s farm-out deal with Shell will be “transformational” in its North Sea growth plans.

Yesterday CLNR announced it will farm-out 70% of its P2552 licence to Shell, along with the option for the energy giant to acquire a 50% stake in the P2437 licence.

CLNR saw its share price surge following the announcement, and CEO Graham Swindells said it gives them “clear line of sight” with Shell set to bear most of the costs.

He believes the deal will raise the profile of the company and offers a platform for growth as it aims to take on more licences in the next round from the Oil and Gas Authority (OGA).

He said: “This takes us from a company with a portfolio of highly prospective assets to a company that’s trying to position ourselves as one of the leading independent exploration and appraisal-focussed companies in the North Sea.

“A big part of this is it provides a platform for us from which to work and build on these assets that we have farmed out.

“We have the intention to further expand and diversify our portfolio when the 32nd licensing round is opened up, hopefully in the summer of this year.” read more
