Firms submit bids for Ruwais sulphur terminal expansion

5 September 2024

Register for MEED's 14-day trial access 

Contractors have submitted technical bids for an Adnoc Gas project to expand the second sulphur handling terminal (SHT-2) at Ruwais.

The Ruwais SHT-2 terminal receives 22,000 tonnes a day (t/d) of solid sulphur granules from the Habshan gas processing plant and about 11,000 t/d from the Shah sulphur station through the Etihad Rail network.

Contractors submitted technical bids for the project by the deadline of 30 August, according to sources.

MEED previously reported that Adnoc Gas, the natural gas processing business of Abu Dhabi National Oil Company (Adnoc), issued the main engineering, procurement and construction (EPC) tender for the project in August. 

The main objective of the project is to increase the sulphur handling capacity of SHT-2 to 27,000 t/d, along with other upgrades to the unit.

The granulated sulphur received at Ruwais SHT-2 is shipped to Adnoc’s customers worldwide via ships, with ship loaders available at its jetty facilities.

The facilities at Ruwais SHT-2 are experiencing high levels of sulphur dust because of the breakage of the solid granulated sulphur.

Adnoc Gas, in its expression of interest (EoI) document for the project, attributed this "to various reasons like multiple handling of the products, inadequate dust suppression and extraction systems in place that affect HSE [health, safety and environment] aspects as well as the facilities integrity and reliable operation”.

Adnoc Gas issued the EoI document for the Ruwais SHT-2 expansion project to contractors on 29 February, with contractors submitting responses by 14 March, MEED previously reported.

The scope of work on the Ruwais SHT-2 expansion project covers the following:

  • Dust collection and wet scrubber system – Replacement of eight wet scrubber systems
  • Rail car unloading building dump hopper modification – Upgrade of the system is required
  • Magnetic separator – Installation of new magnetic separators and demolition of existing magnetic separators
  • Metal detectors – Installation of new metal detectors
  • Fire and gas system upgrade – Implementation of recommendations of fire and gas systems mapping study performed during front-end engineering and design
  • Rail car unloading building drainage upgrade – Provision of new drainage system and modification for diverting effluent to appropriate existing systems outside the building.

Adnoc Gas manages a sulphur-handling facility in the Ruwais industrial area located 240 kilometres southwest of the city of Abu Dhabi.

The terminal consists of two sulphur handling units, SHT-1 and SHT-2, designed to receive liquid sulphur from trucks, pipelines and ships; produce granulated sulphur; and export granulated and liquid sulphur by ship.

Adnoc Gas has, separately, undertaken a project to expand the capacity of Ruwais SHT-1. Contractors submitted commercial bids for that project on 1 July, MEED previously reported, with the project operator presently evaluating those bids.

The project aims to increase the sulphur granulation capacity of the two SHT-1 berths from 8,750 t/d to 9,900 t/d. 

The overall SHT-1 expansion project is valued at an estimated $400m, according to sources.

  • Fluor wins feed contract for key Bahrain aromatics facility

    22 July 2026

    Bahrain’s Gulf Petrochemical Industries Company (GPIC) has awarded US-based consultant Fluor a contract for front-end engineering and design (feed) on an aromatics facility in the country.

    The project will be an expansion of GPIC’s existing petrochemicals facility in Bahrain’s downstream complex in Sitra, which produces ammonia, urea and methanol.

    The new aromatics facility will utilise “commercially-proven process technologies” to produce approximately 1.2 million metric tonnes a year (t/y) of paraxylene and 500,000 metric t/y of benzene, Texas-headquartered Fluor said.

    Paraxylene and benzene are critical building blocks for plastics, polyester fibers and packaging materials, supporting global demand for high‑performance consumer and industrial products.

    Founded in 1979, GPIC is a joint venture of Bahraini state energy enterprise Bapco Energies, known at the time as Nogaholding; chemicals giant Saudi Basic Industries Corporation (Sabic); and Petrochemical Industries Company – a subsidiary of state energy conglomerate Kuwait Petroleum Corporation. The three partners hold equal stakes of 33.3% in GPIC.

    GPIC utilises locally available natural gas as feedstock to manufacture high-quality chemicals and fertilisers for domestic consumption and export, including 1,200 metric tonnes a day (t/d) of ammonia, 1,200 metric t/d of methanol and 1,700 metric t/d of granular urea.

  • Riyadh seeks contractors for Expo Icon structure

    22 July 2026

     

    Expo 2030 Riyadh Company (ERC), which is tasked with delivering the Expo 2030 Riyadh venue, has asked contractors to express interest in the construction of the Icon, one of the key landmarks at the site.

    The structure will be located at the entrance of the Expo 2030 Riyadh site, within the Collaboration Precinct.

    ERC issued the expressions of interest notice on 20 July. The deadline for submissions of interest is 23 July.

    The structure will be connected to the metro station and will serve as a gateway to the event.

    It will be 66 metres tall and will comprise an observation platform, food and beverage outlets and other features.

    The total built-up area will be approximately 16,279 square metres and it will be able to accommodate more than 1,450 visitors an hour during the event.

    The contract duration is 29 months from the start of construction.

    ERC tendered the contract for the construction of the Saudi Arabia pavilion at the site in May.

    The pavilion is a major asset located within the venue's KSA District, on the eastern side of the Expo 2030 Riyadh masterplan, within the Loop of Nations district.

    Construction progress

    The tendering of the pavilion structure followed swift progress on the site’s infrastructure development works.

    In April, ERC awarded two contracts for the next phase of infrastructure works at the site to local firm Al-Yamama Company.

    The scope covered the construction of road networks and infrastructure for water, sewage, electricity, telecommunications and electric vehicle charging.

    These awards followed ERC’s January award of an estimated SR1bn ($267m) contract for initial infrastructure works at the site to local firm Nesma & Partners. That scope covered about 50 kilometres of integrated infrastructure networks, including internal roads and essential utilities such as water, sewage, electrical and communications systems, and electric vehicle charging stations.

    The overall infrastructure works – covering the construction of main utilities and civil works at Expo 2030 Riyadh – are split into three packages:

    • Lot 1 covers the main utilities corridor;
    • Lot 2 includes the northern cluster of the nature corridor;
    • Lot 3 comprises the southern cluster of the nature corridor. 

    The masterplan encompasses an area of 6 square kilometres, making it one of the largest sites ever designated for a World Expo event. Situated to the north of the Saudi capital, the site will be located near the future King Salman International airport and will provide direct access to landmarks within Riyadh.

    The Public Investment Fund, Saudi Arabia’s sovereign wealth vehicle, launched ERC – a wholly owned subsidiary – in June 2025 to build and operate facilities for Expo 2030.

  • EtihadWE tenders $150m Ajman substation project

    21 July 2026

    The UAE’s Etihad Water & Electricity (EtihadWE) has tendered a contract to build three new substations in Ajman.

    Estimated to cost $150m, the project involves the construction of three new 132/11kV substations in the Bahya, Rumaila and Liwara districts. It also includes associated 132kV underground cabling works to connect the substations to the existing transmission network.

    The bid submission deadline is 10 August.

    According to tender documents, the project will add distribution capacity to support load growth and improve the security of electricity supply in the emirate.

    The scope of work includes site preparation, construction of three substation buildings and foundations, installation of 132kV GIS/AIS switchgear, 132/11kV power transformers and 11kV switchgear, as well as protection, control, Scada and telecommunications systems.

    Etihad WE is responsible for electricity and water services in Ajman, Umm Al-Quwain, Ras Al-Khaimah, Fujairah and parts of Sharjah. The utility has been investing in new substations and transmission infrastructure as electricity demand continues to increase across the Northern Emirates.

    This includes a 132/33/11kV substation project on Al-Marjan Island in Ras Al-Khaimah. Construction work is ongoing on the project, with Maetal Dubai serving as the main contractor.

    EtihadWE is also finalising a new masterplan that will cover network capacity requirements and expansion priorities for the next 10 to 15 years.

    In June, Abdulla Al-Khemeiri, chief operations officer, told MEED: “We are currently reviewing it, and we need to obtain shareholder approval first. Once it is approved, it will be released, hopefully by the end of the year.”
