We want to make it Simple to Be Safe.

Simple to Be Safe

Maersk Drilling truly wants to bring our people Out Of Harm’s Way. We are challenging the way we work with safety, not only as a priority but as a commitment.

This starts with asking our frontline colleagues what they need to stay safe and efficient. We are thinking out of the box for ways to eliminate risk. Nobody should ever be in doubt as to how to perform a task safely.

We are removing complexity and reducing administration so we have more time for safety conversations. We are innovating new solutions to digitise and make our work processes more visible.

Smarter Drilling for Better Value is Maersk Drilling’s response to this. It combines innovative technologies with new commercial models to reduce waste and inefficiency across all the activities delivered on a well.

We provide solutions that plan, orchestrate and integrate the services involved in a drilling campaign. By improving co-ordination and simplifying

interfaces across the supply chain, we aim to reduce overall NPT, increase efficiency and improve safety for our customers.

We’re also building new types of alliances with our customers that take a longer-term time horizon, align incentives and create value for the partners. Together, we’re lowering the cost per barrel and improving the competitiveness of offshore oil and gas.

Offshore oil and gas is in a race to produce the most competitive barrel of oil. With dozens of different suppliers and multiple interfaces involved, the process of delivering a well safely, on time and within budget has become more complex for operators than it needs to be.

Non-productive time (NPT) is often 20–25% across all

suppliers on a well

20–25% NPT

It can take over 60 suppliers and 6,000 invoices to drill

an offshore well

60+ suppliers

Every hour spent on a well counts – there’s a lot to play for

Our joint challenge:


Rig capabilities

Maersk Highlander8


A flat main deck with conventional cantilever box and derrick. The cantilever and derrick can be skidded between well locations with minimum rig up and rig down. This also allows for full drilling loads, irrespective of movement from centre line to port or starboard.

The NOV drilling package enables offline handling of all tubular types and incorporates automated sequencing of operations as well as anti-collision systems. Specifically designed material handling capabilities allow for deployment of XMTs and the ability to handle HP risers.

The Maersk Highlander is a 400ft Friede Goldman jack-up 2000E rig, with design optimisation inputs from Maersk Drilling.

Operating in MPD modeDuring the start-up phase the rig was modified to be able to operate in MPD mode. This conversion was installed and tested within budget and time.

The drill crew were trained on the MPD techniques on the Highlander simulator at RGU (Robert Gordon’s

University) along with Maersk Training centre and 3rd party personnel. By applying this method, the rig and crew successfully drilled four ultra HPHT 12¼” and 8½” well sections in the Culzean field.

Culzean first gas – 10% below initial budgetIn June 2019, a milestone was reached by Maersk Highlander and Total at the Culzean platform when the first gas started to flow. The achievement was delivered well ahead of schedule and with capex savings of more than £390m.

This is just the latest of a long list of accomplishments since Maersk Highlander commenced operations

in August 2016. Since arriving at Culzean, the rig has successfully drilled 3 HPHT wells, and performed major upgrades to Well Control and Mud systems, all supported by a safe and efficient performance from the rig crew. By June 2019, the rig was 889 days LTI free and 9-10 months ahead of the planned schedule.

Well control equipment

The Highlander is designed so that handling and operating of well control equipment has minimum impact on the well delivery and time schedule. Handling systems and hoses remain connected, minimising installation time.

Cameron 18¾” 15,000psi, double BOP

Cameron 18¾” 10,000psi annular

1 x 125MT BOP forklift crane

Cameron control system

NT2 connector rather than bolted flange connection for reduced nipple uptimes

BOP can be tested offline to full working pressure as hoses are connected at all times

Glycol unit installed at the choke manifold

15K BOP hoses and control hoses are permanently rigged up to reduce nipple up/down time

Equipment


Drill floor

Maersk Highlander is fitted out with an NOV topside and driller’s cabin, a design that allows offline handling of tubulars to be carried out at the same time as main well centre operations. It incorporates anti-collision systems.

NOV TDX 1000, 907MT capacity link-tilt and block retract system, with pipe handler

Max continuous torque of 91,000ftlbs at 100rpm, intermittent torque of 84,800ft-lbs

NOV Amphion integrated drilling control system, with the ability to read and store casing make-up graphs

Driller and AD in the same driller’s cabin enables better communication. Redundancy within controls since driller and AD chair are identical

2,000,000lbs capacity NOV 4,600HP draw-works grooved for 2” drill-line

Dual pipe handling. While one string is working at the main well centre, offline casing, tubing, drillpipe and bottom hole assembling can be built or laid out from the mouseholes, reducing the time spent on the critical path

Derrick max setback load: 475MT. Dimensions: 170ft x 40ft x 45ft (52m x 12m x 14m)

Extra Drillers chair for MPD operations

NOV auto iron roughneck ST-160 tubular size range: 3½”–9½” DC. Fitted with automatic MUD Bucket system. As well as 1 x ST120 Iron roughneck. Pipe racking system consisting of two NOV PRS 4i automated hydrarackers, adjustable casing fingerboard, DP/ DC fingerboard and bellyboard with tubular capacity of 4”–14”

Pipe transfer system consisting of NOV raised catwalk to transfer tubulars to the well centre and mousehole

Smart zone management system


Maersk Highlander18


Fluids system

Three high-efficiency gear-driven mud pumps, fitted with p-quip type fastening, provide a high-quality working environment.

The pumps are NOV 14-P-220, 2,200HP triplex pumps rated for 7,500psi with anti-sync mode, which obtains better signals from downhole tools back to surface.

The mud mixing system consists of:

Mud system partially auto/remote operated

Dust collector/recirculation system for bulk system

Cell feeders and controls for automatic dosing from surge tanks

Sack cutting machine with dust extraction

Mud mixing hopper with manual sack table and venturi mixer

Big bag station with dust extraction and metering screw for automatic dosing

Liquid skid for automatic dosing of liquid additives to mixing system

Roller table for internal handling of sacks to manual sack table

6 x NOV VSM 300 high-performance shale shakers located in the cantilever deck to minimise the flow distance from the well centre, with up to 1,800gpm capacity and two vertical degassers

Accommodation

Accommodation is wrapped around the bow leg with office space overlooking the main, cantilever decks and drill floor.

Port block is a quiet area with cabins, while starboard block holds all offices, recreation rooms and service facilities. Maximum POB is 137 persons. The layout allows separation between offices and accommodation, leading to a better working and sleeping environment for the rig crew.


Material handling

Highlander has two distinct handling zones; the cantilever and the main deck. The cantilever, equipped with a pipe deck pipe handler (KBC), allows drilling equipment to be handled by the drill crew while the rig cranes accommodate the rest of the equipment.

Cranes:

NOV PC1891 KCE knuckle boom crane with a lifting capacity of 12MT to transport tubulars from pipe deck to the tubular feeding machine. The KBC can supply the drill floor during heavy weather, as most equipment is stored in the cantilever, reducing dependence on deck cranes. It also has a greater operability criterion than a lattice boom crane (up to 70 knots)

3 x Seatrac deck cranes with 131MT boom, 75MT maximum hoist capacity and 13MT whip line capacities

Hamco support deck Hinged and fixed in one position Load capacity of 0.9T/m2 Footprint 45 m2 Starboard aft. side of the rig

The conductor tensioning unit, which consists of splittable tension support ring and lateral support device (currently not in use, removed due to over platform operations)

Power supply

6 x Caterpillar Model C175-16 diesel engines and AVK 3508B generators, each producing 2,340kW

Power management system has prioritisation and increased black-out prevention built into it

Having six large, powerful engines provides flexibility and redundancy
