Five Reasons to Lay Zap-Lok™ and MPS® Pipelines

A vast volume of subsea pipelines are planned and built
every year to bring the world’s energy supplies from the seabed to the surface.  In an industry continuing to adjust to new
norms, its vital we work together to drive the adoption of ingenious technology
to make the process smarter.

Welding is the predominant method for fabricating pipe
systems across the sector.  But there are
several applications where traditional welded pipe connections become
inefficient, uneconomic or impossible.  Cortez
Subsea works with NOV-Tuboscope to pioneer Zap-Lok™ mechanical connectors into
new markets for pipelay which is faster, stronger and cheaper. 


The Zap-Lok™ technology is proven with more than 7000km of shallow-water,
subsea hydrocarbon pipelines installed worldwide and zero recorded failures in
operation of over 70,000 joints.  That’s
further than from Singapore to Sydney.


You can lay 3.5 – 5km of pipeline in 24 hours using Zap-Lok™
in comparison to a typical welding method which achieves 1 to 1.5km a day.  This means less boat time and less crew.


Zap-Lok™ will dramatically reduce your costs.  When used in conjunction with the Cortez
Subsea designed and patented Modular Pipelay System (MPS®) savings of up to 40
per cent become reality.


The International Maritime Organisation (IMO) has adopted
regulations and mandatory energy-efficiency measures to address the emission of
air pollutants from ships.  Among many
other efficiencies, Zap-Lok™ and MPS® reduce vessel time to shrink our carbon


As an alternative to welding, this method takes advantage of
semi-automation to result in a safer work environment, free from hot-work and

We challenge the conventional to take the design and development of technology from the spark of an idea to through planning to clever application.  If you are interested in Zap-Lok™ mechanical connectors and the MPS® pipelay system contact:

Team Boost for Cortez Subsea

Cortez has more than doubled its team across Aberdeen and
Kuala Lumpur (KL) after being awarded a contract to lay the first ever subsea
pipeline using mechanical connectors offshore Malaysia.

The work will be jointly executed with Alam Maritim Resources
Berhad under our consortium agreement and Cortez will deliver the engineering,
procurement and operational activities from our office in KL.

Cortez Subsea Limited Contract Award in support of the Pipeline System for Tembikai Non-Associated Gas Development

1st April 2019 –
Cortez Subsea Limited have been
awarded a contract by Alam Maritim Sdn. Bhd. to support their recently awarded Pipeline System for Tembikai Non-Associated
Gas (TNAG) Development by Vestigo Petroleum Sdn. Bhd.

Subsea, under its consortium agreement with Alam Maritim will jointly execute
the project scope of work covering the engineering, procurement and operational
activities from their offices in Kuala Lumpur. The work starts immediately and
is targeted for completion in Q4 2019.

TNAG gas pipeline system will be installed from the new TNAG unmanned wellhead
platform via a 60 km, 12” pipeline and fibre optic control cable. The rigid
pipeline will be the first in offshore Malaysia installed using mechanical
connectors, and specifically the NOV-Tuboscope Zap-Lok™ connection, tied into the existing processing
facilities on the Berantai Floating Production, Storage and Offloading (FPSO)
and the Well Head Platform (WHP) with flexible risers connected to the rigid
pipeline with diverless connections.

Cowie Managing Director of Cortez Subsea said, “This is a fantastic achievement
for Cortez Subsea and our partner Alam Maritim. We have worked over several
years with National Oilwell Varco (NOV)-Tuboscope to deliver the Zap-Lok™ mechanical connector into the Malaysian oil & gas
offshore market. Our partnership with Alam Maritim enables us to deliver our
first subsea pipeline project offshore Malaysia, and we look forward to working
together in the future.” Further he added

Bin Rahmad, Group Chief Operating Officer of Alam Maritim Resources Berhad said,
“We are delighted to have been awarded a contract on a project by Vestigo
Petroleum and the confidence they have in us to work on their TNAG pipeline
system.” “Our partnership with Cortez Subsea has brought the ability for us to
apply new technologies and methods for the subsea pipeline installation to the
Malaysian offshore environment and the first subsea pipeline to be installed
using mechanical connectors,” he added.

Line Pipe Product Director, Dr Benjamin Chapman said “the foresight of Vestigo
Petroleum in implementing Zap-Lok and associated services has proven to be successful
and is a key project for NOV. This will demonstrate for the first-time in
Malaysia, tried and tested technology and expertise practised offshore in other
parts of the world.”

Cortez Subsea Coiled Tubing Pipelay Project

Cortez Subsea recently completed the laying of 80 km of 4.5" coiled tubing pipe (CTP) in the Baltic Sea for Lotos Petrobaltic to facilitate the transportation of gas from the B8 field platform to the Energobaltic CHP Plant in Wladyslawowo

The Cortez Subsea scope consisted of pipeline installation engineering plus supply of installation equipment, all offshore personnel and management of the pipeline installation operation

This project showcased Cortez Subsea's ability to deliver not only our Zap-Lok pipelay product but also more conventional methods in a fast and very cost effective manner

Cortez Subsea takes delivery of first Modular Pipelay System (MPS®)

Cortez Subsea have recently taken delivery of their patented and first in series Modular Pipelay System (MPS®). The MPS® offer a key differentiator versus traditional offshore pipelay, it allows the use of mechanical interference connectors, including the NOV Zap-Lok™ to be used in place of traditional welding, allowing a pipeline to be laid from a standard DP 2 vessel thereby eliminating the cost of a specialist pipelay vessel and significantly decreasing installation time. The MPS® comprises all the equipment necessary to perform pipelay on standard pipe sizes of 4-inch to 16-inch in an S-lay configuration in water depths up to 150mtr. The nature of the MPS® means it is adjustable in width and length to cater for available deck space and the amount of product to be installed. Cortez Subsea intends to develop further MPS® systems by 2020, enabling us situate MPS® systems in various global locations and allow quicker mobilisation for pipeline installation projects.
