About

We proudly serve a broad range of clientele including the leading oil majors, offshore contractors and state-owned oil companies, providing underwater maintenance and repair services to drilling rigs, semi-sub operators, FPSO owners, flotels, and more.

With over 200 full-time diver-technicians, supported by project managers and specialist engineers, we have the depth of in-house expertise to safely handle a wide range of maintenance and repair tasks. We undertake this in full class compliance and cooperation with overhaul specialists around the world to provide a simple, complete safe turn-key solution for your project, minimizing down-time and any associated costs.

FADLAN is well known for generating direct savings in scheduled thruster overhauls and repairs, with de-mounting and re-mounting via our proprietary technology thereby minimizing the cost and time required.

In addition, as the leading underwater class A wet-welding specialists and underwater project managers we can also provide asset integrity repair work for assets to deliver strategic, long-term life-time extension repair projects on older FPSO’s and other units in locations like Africa, Brazil, the Caribbean, Americas, Singapore and Asia-Pacific. Helping our clients to extend the safe and useful utilization time of their assets (via fully class approved permanent wet-welding techniques) and avoiding allocation of high capex budgets for asset renewals.

Specialized Underwater Maintenance and Repairs

FADLAN is also able to offer our specialist underwater ROV hull cleaning and inspection services for the offshore floating production sector. Using in-house proven technology, we have cleaned offshore FPSO and FSO units in Europe and other locations, over a wide range of biofouling conditions- both micro and macro-fouling.

This ROV hull cleaning can also serve as a useful condition monitoring role and this can often be combined with other services like class in-water survey inspections by either diver or inspection ROV services, anode replacement maintenance, or repairs to overboard like sea chests or scrubbers.

In the event you have an offshore underwater requirement that is not mentioned above, please contact us to discuss your specifics.

Services

Underwater Scrubber/Sea Chest Installations & Repairs

FADLAN has developed solutions for ships needing to install scrubber system afloat at lay berths where dry docking is not available, expensive or time consuming.

FADLAN has developed solutions for ships needing to install scrubber system afloat at lay berths where dry docking is not available, expensive or time consuming. New sea chest and overboard discharges can be installed while the vessel is still in service as a pre-planning step for scrubber installation in a lay berth. New spool pipe can be installed and coated to protect spool pipe from corrosive scrubber wastewater afloat while the vessel is in service or during the off-hire time when scrubber is being installed to meet classifications society’s requirements as permanent fixing.

Underwater Rudder/Stabilizer Exchanges & Repairs

FADLAN has revolutionized the underwater methods of repair of rudders and stabilizers. By using underwater cofferdams (either atmospheric or hyperbaric), fully approved mechanical or weld repairs can be performed to rudders and stabilizers. If underwater removal or extraction is required for a rudder or stabilizer, FADLAN floats damaged stabilizers or rudders away from the vessel using the aqueous environment as a crane. Buoyancy control solutions have been developed for underwater lifts up to 300 tons. Underwater seal replacement, including bonding of new seal rings, is possible for stabilizers without taking the vessel out of service.

Permanent underwater wet weld repairs to eroded rudder surfaces and weld seams, dewatering of rudder blades and mechanical repairs to Hi-Lift rudders is all available globally through the expert technicians of FADLAN.

Permanent underwater wet weld repairs to erosion or cavitation damage, after a case by case class approval

Prior to a new sea chest being installed and welded to the hull internally FADLAN can attach a heat bearer on the shell plate as required by class so the internal welding can be done afloat. On completion and pressure testing of the new sea chest FADLAN diver / welded using pre-made negatives of the sea chest grating and with a hydraulic track saw can precision cut the hull opening for the gratings. The grating mounting hardware can then be targeted and welding in place using class approved wet welding procedures. Since the first scrubbers started coming online in 2012 in the cruise ship industry FADLAN has been solving the issues of new sea chest and overboard instillations afloat.

In addition to new overboard spool pipe installation for scrubber discharges, C has also been involved with repairing and replacing existing spool pipes that were not properly protected when first installed. This can require a renewal of the spool pipe as a permanent repair to remove conditions of class or a blasting, built up welding in pitted areas and building up the pipe section with specialized coating depending on the vessel’s next scheduled docking. The customer has options to keep the scrubber in operation using the most cost-effective solution.
