Overview

CTS was contracted by a leading oil and gas major to conduct a Routine Major Service HVAC M-101 A at the PHE-5 area. The service required that acceptable environmental conditions were maintained with respect to temperature, pressurisation, ventilation rate, fresh air requirements, vibration noise level for comfort of occupants, equipment functionality, module integrity and safety.

We supplied detailed construction designs for installation and arranged the procurement of the required equipment. To ensure satisfactory functionality we expertly verified the system to ensure its safe operation including good accessibility to all parts and components for later inspection, repair and maintenance.

Project Brief

CTS was invited by the owners to inspect and execute the retrofit on a Turnkey basis for a series of 5 container vessels to increase the refer carrying capacity by 20 percent. The client required ship specific adaptation and fabrication/installation of the new ducts & fans based on CFD calculations.

The CTS team was deployed to the vessel to execute following-

• Inspect and produce ship specific execution duct designs and plans.
• Arrangement of steel team with material and equipment to make openings for duct insertion and required strengthening of the deck.
• Exhaust air flow analysis and drawings for new mushroom vents.
• Fabrication and installation of ducts.
• Execute on plans and drawings for new fan installation and old fan exchange.
• Testing and commissioning of the system.

All works were inspected and approved by classification society.

Results

CTS adhered to timelines and varying requirements of the project to achieve the desired result. In view of the complexity of the project clients recognised CTS capabilities and put us in charge to lead other contractors to achieve deadlines, often working in conjunction and providing practical solutions.

Project Brief

Our client called upon CTS to analyse and provide a solution for the HVAC issues faced on-board their jack-up rig. CTS provided expertise with certified personnel to give a custom EPC solution within time.  

• Transformer room: in the peak summer in UAE, the transformer room temperature was going higher than the safe operating conditions.
• Galley System: in the peak summer, outside temperature reaches 48C DB / 30C WB. With the existing system on-board the temperature inside the galley went up to 36 °C.
• PLC Room: cooling was not sufficient, on inspection rust and damage was found on the condenser fins which obstructed optimal heat exchange.

Results

The works were completed and tested to the satisfaction of the C/E well within time and in concurrence to the other ongoing shipyard works.

Project Brief

Anglo Eastern Group, the leading and independent provider of ship management services to ship owners around the world, invited CTS Offshore and Marine to identify and provide an effective solution for the worn out AC units cooling the rider cabin. It was observed that the heavy lift vessel encountered extreme weather conditions which had caused wear down of the AC units.

CTS evaluated the heat-load with respect to weather conditions encountered and presented client with suitable VRV system and work plan to ensure minimum downtime for complete installation, commissioning and testing.

Results

With full support from the technical superintendent and vessel crew, we were able to complete the job in time, safely and with prolific result.

Project Brief

CTS Offshore and Marine Limited was contracted by Prosafe, world’s leading owner of semi-submersible accommodation vessels to provide a turnkey solution for the supply, installation & upgrade of the HVAC system as part of the living quarter’s upgradation in the Rig Safe Concordia.

CTS objective was to deliver the project in time while providing safety and quality to the client. A group of very skilled ex-shipyard mechanical and electrical workers with excellent knowledge mobilized for the project.

Detailed analysis of existing systems and heat load calculations were done to come up with a solution consisting of upgrade and new bespoke containerized blocks to fulfil client requirement.

Results

The complex project came with its own logistical challenge as the system components coming in from all over the globe. It was safely concluded within strict timelines. Project Mechanical Superintendent together with Project Supervisor performed various inspection of the work area during and after the project to ensure that all work done as per ABS rules, regulation and under Prosafe QC satisfaction.
