20 Man Accommodation Extension for SBM

Specialist Services has successfully completed the 20 man accommodation extension project awarded by SBM

On 2nd May 2013, SBM awarded Specialist Services the contract for EPC works for the 20 Man Accommodation module to be installed on a Floating Production Storage and Offloading (FPSO) for deep-water exploration and production offshore Brazil.

Project: 20 Man Accommodation Module for BC-10 ESP Rig-less Intervention System (RIS) Project
Client: SBM Malaysia
End User: Shell Global
Location: Victoria, Brazil
Project Completion: 19th September 2014

Project requirements

SBM had been awarded a project for the implementation of a vertical intervention approach utilizing a purpose built intervention facility mounted on to the BC-10 FPSO production facility. The function of the Rig-less Intervention System (RIS) is to facilitate replacement of worn or failed caisson based artificial lift systems deployed in the BC-10 field.

In order to facilitate the above, an additional modular accommodation for 20 persons was required and SBM awarded the project to Specialist Services. The scope of work included engineering, construction, outfitting, installation of equipment, testing and pre-commissioning of the 20 man modular accommodation. The project was required to be installed on the FPSO meeting the necessary interfaces with the existing accommodation block as well as the vessel itself.


The 20 man accommodation extension was engineered as five separately constructed but formable A60 rated modular accommodation units, each comprising two 2 man cabins with individual toilet / shower facility, split A/C unit, lockers, life jackets, desk, chair and a sofa. The project also included the supply of a sewage treatment plant module (STP), a potable water skid, a 1 meter high master skid as a foundation for the accommodation and STP modules, a walkway enclosure to protect the entrance walkways against blast and vertical and horizontal bumpers to facilitate installation offshore.

In line with SBM’s requirements, the modular accommodation has been designed and manufactured taking into account the essential interfaces between the unit and the existing accommodation block as well as between the unit and the vessel. Considered interfaces included fresh water, sewage, ventilation, electrical power and control systems, personnel access, fire detection and safety.

The accommodation unit is A60 certified with the design review and product certification approved by ABS. The modular accommodation with all installed equipment is compliant with:

  • Hazardous Area Classification – Class I Zone 2, Gas Group IIA
  • Brazilian regulatory compliance (NR13, NR 30 and NR 10)
  • ABS class rules Guide for Crew Habitability on Offshore Installations
  • Bahamas regulations on crew accommodation
  • IMO resolution A.468 (XII), SOLAS Chapter III Regulation 9


The project required complex engineering, coordination and construction due to the specific requirements related with existing interfaces and characteristics of the FPSO production facility. A number of specification and design changes were requested by the end user, which required additional works for vertical and horizontal bumpers, Telecom / PA system installation, walkway enclosure and other elements that were added to the contract during the project execution.

The pre-commissioning of the installed systems lasted around 50 days under close vigilance and inspection by the end user deployed in Specialist Services yard in Abu Dhabi. After successful site acceptance test of the accommodation module by SBM and Shell, the module was weighed and loaded out from the waterfront facility in Mussafah, Abu Dhabi on 19th September 2014.

The modules are planned to be installed and integrated on the Shell Global BC-10 FPSO Espirito Santo, Brazil offshore by March 2015.

The accommodation modules will cater to meet the additional capacity of persons that will be on board during the intervention function of the RIS on the BC-10 field.

48 Module 224 Man Accommodation Extension

Specialist Services announces the successful completion of the 48 module 224 man accommodation extension project for Sea Trucks Group within the agreed 16 weeks production period

In November 2013, Sea Trucks Group awarded Specialist Services the contract for a 48 module accommodation extension required on one of their DP3 offshore construction vessels deployed for accommodation support on the Arkutun-Dagi Project in Sakhalin, Russia.

Project: 48 module 224 man accommodation extension
Client: Sea Trucks Group
Project Completion: 5th March 2014

Project requirements

Sea Trucks Group required a temporary increase in capacity of the accommodation and associated facilities onboard of their offshore construction vessels to support the project in Sakhalin and has subcontracted the provision of the required 48 module 224 man accommodation extension to Specialist Services. With the project expected to commence in Q2 of 2014, an extremely tight production deadline of 16 weeks was agreed, with project completion by 5th March 2014. Considering the limited time available for the production and installation of the accommodation units, Sea Trucks Group has demonstrated a confidence in our capabilities to deliver this project on time. In fact Specialist Services ability to provide an overall solution for accommodation units on a sale and/or hire basis gave us a unique solution which assured the client that the installation was guaranteed to be completed on time.


The project was challenging from the very beginning with the production schedule reduced to 16 weeks and Maritime Labour Convention (MLC) with ABS Ship Rules to be complied with. In order to complete the project on time, engineering and fabrication had to be done in tandem and this could be achieved only through the close cooperation between client, contractor and surveyor. Our in depth knowledge and experience in building such projects allowed us to take on such risk.


Our team worked exceptionally hard throughout all stages of this project. 50 staff and an average of over 200 men in the yards worked daily on the project during the production period, while the Engineering Team prepared and issued over 400 drawings to the client, ABS and shop floor. In the end we completed the project and handed it over to Sea Trucks Group in line with the agreed completion date with the units dispatched within 2 days to the Jebel Ali Port for shipping.



All 48 units are fully compliant to ABS, SOLAS A60 and Maritime Labour Convention (MLC) requirement for Temporary Accommodation and have been completed in line with Sea Trucks Group requirements to be installed on the vessel in four levels. The accommodation extension includes 28 modules with 56 four man accommodation units, 6 modules with conference room and 10 four man office units, two recreation rooms, a galley and mess, as well as locker rooms, laundry units, common wet units, chiller and freezer units, dry stores and a linen store. The design was made to allow eased integration along with flexibility where these units are used. Design head of the structure will allow modules to be placed on Sea Trucks Group entire fleet of vessels and are not just project specific.

The installation of the accommodation extension on the vessel in Batam, Indonesia, has been completed end of May 2014.
