70-Man LQ Complex for Sapura Energy

Specialist Services, a Centurion company, successfully completed a 70-Man Living Quarters Complex for Pegaga Development Project

Sapura Energy awarded Specialist Services an EPCC (Engineering, Procurement, Construction and Commissioning) contract for a 70-Man Modular Living Quarters Complex for Mubadala Petroleum, for the Pegaga Gas Field Project in Malaysia.

Project: 70-Man Living Quarters Complex for Pegaga Development Project
Client: Sapura Energy
End User: Mubadala Petroleum
Location: Block SK320 offshore Sarawak, Malaysia
Project Completion: June 2021

Project requirements

Sapura Energy required a complete turnkey solution for a 70-man living quarters (LQ) complex to be installed on their platform, including design, engineering, procurement, construction, outfitting, installation of equipment, third party approvals, testing and pre-commissioning. The Pegaga Development Project consists of a manned Integrated Central Processing Platform (IPCC), where the LQ needed to be integrated. Based on decades of experience, expertise and track record in providing turnkey LQ projects, in October 2018 the Client awarded the project to Specialist Services.


This permanent offshore 70-man LQ project was executed in modular construction, in lieu of the conventional stick-build construction method. Optimising the size of the modules during engineering offered the full benefits of offsite fabrication, lower shipping costs as well as integration resources required onsite.

The project involved interface between Sapura Energy and Mubadala Petroleum in Malaysia, and Specialist Services teams based in Dubai, India and Singapore, on engineering, project management, techno-commercial, transportation, installation and delivery support.

With total dimensions of 39.16m x 11.8m x 19m, the LQ was constructed in 4 levels and with a helideck on the top.


The modules were completed and shipped in Q2 of 2020 amidst the restrictions during the pandemic. The situation affected the overall subsequent installation schedule at site in Malaysia, especially due to mobilization of personnel required for the supervision, as well as Client’s own overall installation schedule.








From commercial and technical negotiations to contract award in October 2018, from engineering to completion of modules in 2019 and 2020, and from the supervision at site in Malaysia during a pandemic to the project completion – this project involved extraordinary coordination and efforts by the different teams to complete this full turnkey modular LQ project.

Modular Firing Range

CoverSix Shooting Training Range interior

Specialist Services has successfully completed a 2-lane x 15m Modular Firing Range project

CoverSix Shooting-Training RangeSpecialist Services were awarded a contract to design, manufacture, install and commission a 2-lane x 15m Modular Firing Range.

Project: Modular Firing Range
Client: Confidential
End User: Confidential
Location: Abu Dhabi, United Arab Emirates
Project Completion: November 2019

Project Requirements

Specialist Services were awarded the project for the design and manufacture of a modular firing range with the following specifications:

  • 2 firing positions (lanes)
  • 15m firing distance
  • 100% ballistic containment with a Zero Surface Danger Zone
  • 100% fresh air ventilation system
  • Overhead retrievable targetry
  • Bullet Trap
  • Integration of judgemental / use-of-force simulation for laser and live fire training
  • Integration of visual and audio effects systems to create an immersive training environment


Specialist Services proposed a Modular Firing Range (MFR), fully compliant with the specifications and requirements provided from the Client. The MFR consists of two (2) CSC certified modules, joined to create a 100% ballistically-contained indoor firing range, capable of supporting both static and tactical training exercises.

CoverSix Shooting Range Ballistic ContainmentBallistic Containment

To ensure ballistic containment of the MFR, we utilized proven and successfully tested techniques, material, and equipment, which provide 360° ballistic containment with a zero surface and vertical danger zone (SDZ/VDZ). This was achieved through lining the interior walls, floor and ceiling with 12mm thick SSAB Hardox AR500 steel plates. We combined these with BSW Regupol E43 shredded rubber tiles, which were offset from the steel plate to prevent ricochet or backsplash towards the origin of fire, even in the event of a negligent discharge.

CoverSix Shooting Range Bullet TrapBullet Trap

The Client opted for a Granulated Rubber Bullet Trap, which is located directly behind the 15m target position, to capture the majority of rounds fired downrange. The bullet trap consists of a mild steel frame supporting a sheet steel platform, with a thick layer of rubber granules placed on top of the platform. The rubber granules provide a 60cm thick layer on the platform, which is positioned at an angle of 37 degrees. Due to the layer of rubber granulate, when rounds are fired into it, the friction between the granules and the rounds decelerates the rounds, bringing them to a complete stop.

CoverSix Shooting Range TargetryTargetry

Each of the MRF’s firing positions includes an overhead retrievable target. To enhance training value, the targets move 15 meters downrange, can be programmed to stop on time or in a preloaded scenario, and stop or move with intervals of 1m. To help create an immersive training environment, the targets also have back and front lighting, strobe and distraction lighting.

Air Conditioning and Mechanical Ventilation

A key component of the MRF is the Air-Conditioning and Mechanical Ventilation (ACMV) system. The MFR was delivered with a pre-packaged and fabricated ACMV system, designed to ensure a minimum airspeed of 0.38m/s at 1.5m above finish floor level, and a laminar airflow along the length of the range with no eddies or backflow of ventilation air allowed. To comply with environmental regulations and best practices, the ACMV system was fitted with a three (3) stage filter system for the exhaust air. The system consists of MERV 6 – 2″ pleated pre-filters, MERV 14 stiff pocket bag filters, and high-efficiency particulate air (HEPA) 99.97% at 0.3- micron filters, ensuring that all contaminants and toxins generated during firing are not discharged into the atmosphere.

Specialist Services has successfully completed the ETR and ICR Buildings project awarded by Tecnicas Reunidas

Tecnicas Reunidas (TR) awarded Specialist Services the contract for the supply of an Electrical Technical Room (ETR) and an Instrument Control Room (ICR) to be used on the ADOC’s Hail Oil Field offshore Abu Dhabi.

Project: Supply of ETR and ICR buildings for Hail Oil Field Development Project
Client: Tecnicas Reunidas
End User: Abu Dhabi Oil Company – ADOC
Location: Hail Oil Field offshore Abu Dhabi
Project Completion: 17th April 2017
ETR dimensions: (L) 34 x (W) 11 x (H) 10.8 m
ICR dimensions: (L) 21 x (W) 8.3 x (H) 9.4 m

Project requirements

Abu Dhabi Oil Company (ADOC) intend to develop the Hail Oil Field located approximately 10km South of Mubarraz Island in the shallow water areas of the Arabian Gulf and 100km West of Abu Dhabi. This development aims to achieve a peak in oil production of 21,000 BPD from the Hail Oil Field. The oil shall be produced from the Thamama Zone A, B and F reservoirs and require some gas injection and gas lift for oil recovery. Tecnicas Reunidas (TR) had been awarded a project of the Hail Oil Field development Early Production Scheme (EPS) phase.

In order to facilitate the above, the prefabricated containerised type Electrical Technical Room (ETR) and Instrument Control Room (ICR) were required and TR awarded the project to Specialist Services. The scope of work included design, engineering, manufacturing, installation of equipment, interconnection cabling, inspection, testing, pre-commissioning, packing, shipping and supply of ETR and ICR buildings.

The buildings were required to be prefabricated, self-contained, skid-mounted, factory manufactured, completely assembled, wired and tested at the factory prior to being mobilised to the site. Other requirements included the provision of the HVAC system, for the buildings mounted on skids in non-hazardous areas, false floors, HSSD and NOVEC Firefighting systems, a minimum of 2 hours fire rating for external walls, roof, floor and doors, and also to be blast-resistant.


The ETR and ICR buildings have been designed, manufactured and supplied in line with ADOC’s requirements. At the beginning, our engineering team worked exceptionally hard to engineer the solutions that would satisfy client’s specifications, and additional design change requests from the client were also successfully implemented during project execution.

The structural design of the buildings was frozen by the end of October 2016. Detailed engineering and fabrication had to be done in tandem to complete the project on time, as required by the contractor at Hail Field. We timely achieved this through close cooperation with the contractor and third party inspectors.

The project was challenging due to the unusual completion schedule for both buildings: 22 weeks for ICR and 26 weeks for ETR. Specialist Services Mussafah yard team in Abu Dhabi worked tirelessly for three months to complete the project in this short lead time, demonstrating outstanding dedication and excellent work.

In-land transportation of ETR to Mussafah Port Jetty was a major challenge due to its width and height. However, Specialist Services, together with their transporter, managed the operation well with proper planning and utmost care. Prior permissions from Abu Dhabi Municipality, Road Transport, Traffic and Mussafah Port authorities were obtained for smooth operations.


The project required complex engineering, coordination and construction due to the specific requirements related with existing interfaces and characteristics of the Hail Oil Field Terminal. A number of specifications and design changes were requested by the client, which resulted in additional works.

The pre-commissioning of the installed systems lasted around 20 days under close vigilance and inspection by TR, Mott MacDonald (PMC) and ADOC staff deployed at the Specialist Services yard in Abu Dhabi.

After a successful site acceptance test of the ETR and ICR buildings by TR and ADOC, these heavy structures were weighed using hydraulic jacks & load cells arrangement at the Specialist Services yard in Abu Dhabi. ICR weighing operation was carried out on 13th April 2017 using 10 load cells, while ETR used 18 load cells on 16th April 2017. ICR and ETR weighed 114 Ton and 237 Ton respectively.

We completed the project and handed it over to TR at Mussafah Port Jetty, Abu Dhabi, on 16th and 17th April 2017 in line with the agreed completion schedule. Both buildings were transported to Mussafah Port with the help of SPMTs in-land transportation.
